`Preparing Adobe” PDF files
`for high—resolution printing
`
`Today's prepress workflow works, but it doesn't really flow
`
`Commercial printers and service providers are working hard to improve their ability to produce reliable,
`consistent, and predictable output on increasingly tight schedules. The current digital prepress process works,
`but it’s fraught with problems that challenge this goal. Most commercial printers and service providers re-
`ceive files in their native file format. These handoffs invariably have problems: missing components (fonts or
`graphics), missed deliveries (problems with modem or other electronic deliveries), accidental changes, un-
`predictable PostScript' language files (created from native applications), and enormous file sizes. In addition,
`service providers have to maintain different versions of many different applications to support the range of
`requests they get from you and other customers—a requirement that adds training and software/hardware
`compatibility issues to the mix. What they need is a more streamlined, PostScript-based process that’s robust
`enough to meet their high quality standards.
`
`Adobe Systems has a solution that addresses this fundamental problem. The solution is based on two core
`technologies: Adobe Acrobat‘ 3.0 software with its Portable Document Format (PDF) files and Adobe
`PostScript' 3"‘ printing technology. We developed these solutions by working with service providers and
`customers like you to identify how to streamline the printing process. The result is a portable, device-
`independent solution that overcomes many of the problems encountered in the old process. Here’s how it works:
`
`D Step One: You develop your illustrations or publications using your favorite software.
`
`P Step Two: Before handing off to your commercial printer or service provider, you use Adobe Acrobat
`Distiller‘ 3.0x to create a PDF file. This PDF file contains all of the font, graphic, and other layout infor-
`mation necessary to print a high—resolution version of your document.
`
`Note: You either create a composite or preseparated PDF file, depending on the content of your docu-
`ment. A composite PDF file contains all the information necessary for printing separations, but the
`actual separation occurs at the RIP your service provider uses. A preseparated PDF contains a page for
`each of the separations required by your document. For example, if you create a preseparated PDF file
`for a two-page, CMYK print job, the PDF file would contain eight pages—one for each separation re-
`quired. (For additional information see page 11, “Using a preseparated PostScript/PDF workflow.”)
`
`> Step 3: You hand off the PDF file to your service provider.
`PDF files streamline the printing process, while providing more consistent and reliable results. In particular,
`they reduce or eliminate delays from missing components or unstable files, better communication between
`you and your printer, and much smaller rework costs. Why? Because the PDF file format offers so many
`distinct benefits. PDF files are:
`
`P Complete—They contain all the fonts, graphics, and page layout information necessary to display
`and print the file exactly as you laid it out.
`
`P Compact—PDF supports a variety of compression methods (both lossy and lossless compression),
`creating smaller files that are easier to transmit and faster to print than the native application files.
`
`D Portable—One of the key benefits of a PDF file is its page, platform, application, and device inde-
`pendence. You can print high-resolution PDF files on any Adobe PostScript 3 output device with the
`same high-quality results from each. This gives you greater flexibility than in a PostScript workflow.
`
`D Reliable—Acrobat Distiller interprets the original PostScript file, creating cleaner, more reliable
`PostScript for final output.

`
`

`
`D Editable—If you create composite PDF files, you maintain editing control over the final file. You or
`your service provider can do simple late-stage text and graphic editing in Acrobat Exchange’ software
`using third-party plug-ins. PDF files are page independent—aHowing you to sort, extract, insert pages
`without returning to the native application file.
`
`P Extensible—You can add third-party plug-ins to your Acrobat toolkit to perform a number of
`supplementary tasks. (For details, visit the Adobe Web site at this URL: httpzz[www.pluginsource.com[.)
`
`In addition, your service provider will benefit from the following:
`D Adobe PostScript‘ 3"—providing in-RIP technologies (e.g., separations and trapping) enabling a
`smaller, more efficient composite PostScript workflow as opposed to a larger, less efficient “host-based"
`color separated workflow.
`
`P Direct PDF Printing—printing PDF files without having to select a print command through an
`application increases workflow productivity. Direct PDF printing also decreases operator errors by
`creating drop or hot folders defined with specific printing parameters and job specifications. (Check
`with your service provider or printing device manufacturer whether the direct PDF printing feature is
`supported. Not all Adobe PostScript 3 printing devices include the Direct PDF printing feature because
`it requires an actual hard disk for file storage.)
`
`This document guides you through the basic steps of producing high-quality PDF files for high-
`resolution output. It focuses mainly on the composite PDF workflow, but it also provides some basic
`information about the pros and cons of a preseparated PDF workflow. It explains the importance of
`producing good PostScript files for distilling (creating PDF files) and describes how to do this. The
`document also walks you through key Iob Options in Acrobat Distiller, and offers some baseline recom-
`mendations that will ensure optimal PDF files. We recommend working closely with your service provider
`to develop a smooth PDF-based workflow that works for all of you.
`
`Composite versus preseparated PDF files
`The first step in producing a high—resolution PDF file from your document is to decide whether to create a
`composite or preseparated PDF file. As a rule, we recommend choosing a composite PDF workflow because
`it offers these key benefits:
`
`D On-screen viewing (or soft proofing)—You and your service provider can review the file in its final
`form until it's output. You can double-check graphic placement, wording, and other file details. That
`way, you can catch problems before going to press and avoid costly rework.
`
`> Simple text and graphics editing—You or your service provider can edit the PDF file if you find a
`problem or have an eleventh-hour change.
`
`> Faster, more efficient file transfers—Composite PDF files are tiny by comparison to typical, high-
`resolution PostScript files. A typical PostScript file with an 8-up imposition with embedded high-
`resolution images can consume anywhere between 600 MB and 1 GB of disk space. In addition, your
`service provider has to transfer it over their network multiple times——once for each separation. A PDF
`file offers a compact, one-shot transfer—making it simpler for everyone.
`
`D The right use of in-RIP functionality—Your service provider can perform trapping, separations,
`and late binding and file editing, all at the RIP. Furthermore, page independence in PDF files supports
`the Adobe PostScript Extreme workflow. (For details on Adobe PostScript Extreme", see the Adobe Web
`site at this URL: http://www.adobe.com[print/main.html.)
`
`If you choose a preseparated PDF workflow, you’ll create larger files and lose the viewing, and editing capa-
`bilities. However, you must use a preseparated PDF workflow for documents that contain certain graphic
`file formats or features—specifically, duotone EPS files, colorized TIFF files, DCS images, and spot-color-to-
`spot-color gradients. These were designed to support a preseparated PostScript workflow, and don’t include
`the information necessary to color separate them from a composite PostScript file.
`
`Adobe is working with its industry partners to resolve this issue in the near future. In the meantime,
`using a preseparated PDF workflow offers you a more reliable and portable (device—independent) prepress
`process than you’ve had in the past. For details about creating preseparated files, see “Using a preseparated
`PostScript/PDF workflow” on page 11 of this document.

`
`Retaining high quality printing information in Adobe PDF files
`One of the challenges you face is understanding how to consistently create PDF files that retain the neces-
`sary information (e.g., fonts, color, links to high-resolution images, and overprint settings) for high-resolu-
`tion printing. The key is understanding the relationship between PostScript and Acrobat Distiller, and how
`this relationship affects the resulting PDF files. The PostScript imaging model is the heart of Adobe Portable
`Document Format (PDF) files. After all, Acrobat Distiller 3.0x only accepts PostScript or Encapsulated
`PostScript (EPS) files. You need to know what variables affect this relationship and how to handle them
`quickly and efficiently.
`
`Like a PostScript printing device, Acrobat Distiller interprets PostScript code. However, instead of
`creating printed output from that code on paper, film, or a printing plate, as a PostScript printing device
`would, Distiller creates a PDF file. Just as a document printed from a PostScript printing device is an exact
`representation of the original electronic document, so too is a PDF file. While Acrobat Distiller 3.0x is an
`Adobe PostScript Level 2 interpreter, Distiller does not actually “raster” the file, so it is not a PostScript
`raster image processor (RIP).
`As the Portable Document Reference Manual notes on page 8: “PDF files represent text and graphics
`using the imaging model of the PostScript language. Like a PostScript language program, a PDF page
`description draws a page by placing ‘paint’ on selected areas.” The quality of the page description drawing
`process is directly related to the quality of the PostScript file that Distiller interprets. If, for example, the
`PostScript does not include required fonts, proper paper sizes, or custom/spot color information, neither
`will the resulting PDF file.
`Producing quality PostScript files, and therefore quality PDF files, involves planning. A complete
`workflow for creating high-resolution PDF files is a five-step process:
`
` Peésrhrinins «
`
`'whether to use
`composite or
`preseparated ’
`PostScript
`
`Preflighting
`Prior to creating a PostScript file for distilling, you must start with a “print-ready" native application file.
`What do we mean by print-ready? This is a file that adheres to your service provider’s specifications for
`high-resolution printing. For example, the file:
`
`D doesn’t include any RGB images or colors in a four-color process job
`
`D maintains links to placed graphics and images
`
`D
`
`contains only high-resolution image data (no 72 dpi images)
`
`Preflighting is the industry—standard name for this process. Ignoring this step in the process can result
`in missed deadlines or unexpected charges for rework. We recommend you ask your service provider
`which software they recommend for preflighting files. This will ensure consistency throughout the
`production process. Make sure the recommended software opens your native application files, as well as
`PostScript, EPS, and PDF files. You’ll find the initial investment worthwhile——saving you valuable time
`and money.
`
`Creating composite PostScript files
`Creating efficient, composite PostScript files for high-resolution printing is not as simple as deselecting
`color separations in your native application’s Print dialog box. Here is a list of variables you need to consider:
`
`P Printer driver and PPD selection
`
`Paper size
`Font inclusion
`
`VVVVV OPI comments
`
`Spot-color information
`

`
`

`
`Selecting a printer driver and PPD
`
`For optimal results, we recommend using the Adobe PostScript printer driver (AdobePS"') and the Acrobat
`Distiller PostScript Printer Description (PPD) file. This will ensure you’re creating consistent, device-inde-
`pendent PDF f1les—after all, your PDF file may be printed on more than one device. When you create
`PostScript files for distilling, make sure you’re using the latest version of the AdobePS driver (version 8.51
`for the Macintosh, version 4.2.3 for Windows 95, and version 5.0 for Windows NT‘ 4.0). You can download
`the latest versions of the AdobePS printer drivers from the Adobe Web site at the following URLs:
`
`Macintosh:
`

`
`httpzi[www.adobe.comzsupportserviceicustsupport[LIBRARY[4f06.htm
`
`The Acrobat Distiller PPD file is included with the Acrobat Distiller 3.0x software and is installed in the
`
`Xtras folder in the Adobe Acrobat 3.0x folder (Macintosh) or Acrobat3 > Distillr folder (Windows). This
`
`PPD does not write device-specific information in the resulting Postscript file, so you’ll still be able to select
`certain high—end controls, such as custom paper sizes, for oversized jobs. The Acrobat Distiller PPD was
`originally written to create PDF files for on-screen viewing, so we recommend making the following modi-
`fications to ensure consistent, reliable results:
`
`} Change the DefaultColorSpace value from RGB to CMYK
`5 Change the DefaultResolution value from 600 dpi to 1200 or 2400 dpi (based on your final output device)
`
`To edit the PPD, perform these steps:
`1. Open the Acrobat Distiller PPD in a text editor and locate these lines of text near the beginning of the
`file:
`
`* % ==== Device Capabilities ===============
`*ColorDevice: True
`
`*DefaultColorSpace: RGB
`
`2. Change the DefaultColorSpace value from RGB to CMYK as noted below:
`*DefaultColorSpace: CMYK
`
`3. Locate these lines of text further on in the file:
`
`*% Multiple Resolution support for Distiller 3.0 ==============
`*OpenUI *Resolution: Pickone
`*OrderDependency: 50 Anysetup *Resolution
`*DefaultResolution: 600dpi
`
`4. Change the DefaultResolution value as noted below (or set the value to 1200 dpi):
`*DefaultResolut ion : 24 Oodpi
`
`5. Locate these lines of text near the beginning of the file:
`*PCFileName:
`"ADISTILL.PPD"
`*ShortNickName: "Acrobat Distiller"
`
`6. Edit the text to read as follows:
`*PCFileName:
`"CMYKDIST.PPD"
`*ShortNickName: "Acrobat Distiller CMYK"
`
`7. Save the edited PPD file in text-only (ASCII) format to the same location, using the file name
`CMYKDIST.PPD so that you can easily distinguish the edited PPD from the original.
`
`Specifying the appropriate paper size
`
`If your document’s page size (usually specified in an application’s Document Setup dialog box) does not
`account for image—bleeds or printer marks, you'll want to create a custom paper size using your
`application's Print dialog box. The Acrobat Distiller PPD, like an imagesetter PPD, supports custom paper
`sizes. So, specify a paper size that is large enough to accommodate the document’s page size, as well as any
`image—bleeds, printer’s marks, or printer information you want. As a general rule, increase paper size by one
`Revised 9/22/98
`inch when printing with crop marks.

`
`

`
`Note: If you choose the Export Adobe PDF command in Adobe PageMaker‘ 6.5x software (File > Export >
`AdobePDF) to create the PDF file, you may also need to customize the Printer Style you select. (For addi-
`tional information see page 415 in the Adobe PageMaker 6.5 User Guide.)
`
`Including all your document fonts
`
`When you create a PostScript file for distilling, make sure you include all PostScript Type 1 and TrueType
`fonts. This will ensure that the fonts will be available for viewing and printing. Unlike Type 1 fonts, Acrobat
`Distiller 3.0x can only embed TrueType fonts in a PDF file if they’re included in the original PostScript file.
`(See “Renaming the Acrobat Distiller font database file” on page 9 for additional information.)
`
`If you are considering using TrueType fonts for high-resolution printing, we recommend you discuss
`this with your service provider. They may have printing devices or post—processing applications that do
`not contain a TrueType rasterizer which is required for printing these fonts—resulting in your document
`fonts printing in Courier.
`
`Note: QuarkXPress' 4.0x and earlier do not include the document fonts when you save pages as EPS files (as
`opposed to printing a file to disk as a PostScript file).
`
`Spot-color information
`
`The ability to preserve spot-color information in your composite PostScript file depends on the software
`applications and graphic file formats you use. Page layout applications such as Adobe PageMaker and
`QuarkXPress do preserve spot colors applied to their native elements. However, if you’re using other page-
`layout applications or certain graphic files containing spot colors, they may not color separate properly
`from the resulting composite PDF file. For additional information on these file formats, see page 11.
`
`Including trapping information
`
`It is essential to include trapping information in the composite PostScript file for Acrobat Distiller to pre-
`serve it in the resulting PDF file. The page layout application you are using determines what document
`trapping information you can include in the composite PostScript file. (By “document trapping,” we are not
`referring to line art created in a graphics application and placed in a page layout application. Instead, we’re
`referring to trapping applied to native application elements, such as text and drawn elements.)
`QuarkXPress 4.0x and earlier include document trapping information only when creating preseparated
`PostScript files. On the other hand, Adobe PageMaker 6.01 and later include document trapping informa-
`tion in both composite and preseparated PostScript files. Therefore, if you are using QuarkXPress, you
`may need to modify your workflow (e.g., use a preseparated workflow, use a post~processing application
`to trap the file, or use an output device that supports in-RIP trapping). You can also download the Adobe
`In—RIP Trapping plug-in for Adobe PageMaker 6.52 for Macintosh and Windows from the Adobe Web site.
`
`Note: Some raster—based prepress workflows ignore application trapping information, so check with your
`service provider about trapping.
`
`Preserving OPI comments
`
`You can specify that Acrobat Distiller 3.0x read and preserve Open Prepress Interface (OPI) 1.3 comments.
`Acrobat Distiller 3.0x does not read OPI 2.0 comments because it was released before the OPI 2.0 specifica-
`tion was finalized. However, we plan to include support for OPI 2.0 comments in a future version of Acro-
`bat.
`
`If you or your service provider uses an OPI server that reads and writes OPI 2.0 comments, you will
`need to create “fat” PostScript files prior to distilling. This means that all the high-resolution image data is
`included in the composite or preseparated PostScript file. Fat PostScript fles produce larger PDF files, but
`ensure that Distiller uses the high-resolution image data, and not the sampled or low-resolution placeholder.
`
`Customizing Acrobat Distiller Job Options for high-resolution printing
`We’ve covered the variables associated with creating optimized, composite PostScript files. The next step
`in the process is to customize the Acrobat Distiller 3.0x Iob Options. To access these settings, start
`Acrobat Distiller 3.0x, (choose Distiller > Iob Options), or press Command + I (Macintosh) or Control + I
`(Windows). A dialog box appears with four tabs: General, Compression, Font Embedding, and Advanced.
`EVISE
`The selections you make affect how Distiller interprets PostScript files. For example, whether tl16RdQCl.:i]'I91/621;}/I98

`
`

`
`fonts will be embedded, how graphics and images will be compressed and/or sampled, and whether the
`resulting PDF includes high-end printing information such as OPI 1.3 comments.
`This section describes the Distiller lob Option settings and outlines our recommendations for a typical
`high-resolution printing press (2400 dpi/150 lpi). You may need to adjust these settings to suit your
`workflow processes and equipment. These recommendations are intended to give you a baseline from
`which to work—as opposed to the application default settings that are intended to create PDF files for on-
`screen viewing. These settings may differ from the researched, documented settings your service provider
`uses. Therefore, we recommend you work closely with your service provider to identify what your settings
`should be before creating high-resolution PDF files for final output.
`
`Note: When you create PDF files for high-resolution printing, you should always use Acrobat Distiller and
`not the Acrobat PDFWriter. PDFWriter enables you to convert documents to PDF files quickly, but it uses
`the on-screen display (QuickDraw commands on the Macintosh or GDI commands in Windows) to make
`this conversion. Acrobat Distiller, on the other hand, supports PostScript technology-based applications. It
`converts a document’s PostScript file, including its high-resolution printing and color information, into a PDF file.
`
`It is important to understand that the default Acrobat Distiller 3.0x Iob Option settings are designed to
`create very small PDF files—ideal for on—screen viewing. However, these settings will not produce PDF
`files optimal for high-resolution printing. To show the importance of customizing the Distiller lob
`Options, here is a simple table showing what happens when you use the default settings to create PDF files
`for high-resolution printing:
`
`General Job Options recommendations
`The general tab includes file settings and device settings options. Here you’ll specify compatibility, whether
`to use the ASCII format, default resolution, and the default page size.

`
`Compatibility—Select Acrobat 3.0 from the Compatibility popup menu, so your PDF file supports spot
`colors and other Acrobat 3.0x features, such as ZIP compression.
`
`ASCII Format—Leave the ASCII format option deselected so that Distiller saves the PDF file in binary format,
`creating a smaller file.
`
`Default Resolution—Enter the resolution (dpi) of the PDF file’s final output device in the Default Resolu-
`tion text box. The value you enter here affects only vector (object-oriented) EPS files. For example, Distiller
`may use this value to determine the appropriate number of steps for a blend in an EPS file.

`
`

`
`Default Page Size—If the PostScript file you're distilling includes paper size information (and most do),
`you can ignore the Default Page Size option. On the other hand, if you’re distilling an EPS file, enter a page
`size for the EPS file. (EPS files include a bounding box size, but not a paper size.) Distiller uses the values
`you enter in these text boxes when a PostScript file, such as an EPS file, doesn’t include a paper size.
`
`Compression Job Options discussion and recommendations
`The Compression tab includes compression options for text and line art elements. It also includes the
`downsampling and subsampling options, as well as the automatic and manual compression options for
`images. For color, grayscale, and monochrome bitmap images, you can choose whether Distiller samples or
`compresses your images. Selecting these options results in smaller files, but may affect the quality of your
`images.
`Acrobat Distiller 3.0x can subsample or downsample bitmap images. When Distiller subsamples an
`image, it records a pixel in the center of the sample area and replaces the entire area with that pixel; when
`Distiller downsamples an image, it averages the pixels in the sample area and replaces it with the average
`pixel color at the specified resolution.
`Downsampling reduces the amount of information in the image so that only the image data that the
`printer can use is included. We recommend using downsampling to create a baseline—catching those
`bitmap image files that have been scanned at a specific resolution, then scaled smaller in a layout or
`graphic application, unnecessarily increasing the image resolution, and sometimes causing printing
`problems. Acrobat Distiller determines how much image data to include based on the dpi value you enter.
`If the images in the PostScript file already include the appropriate amount of image data for the final
`output device, you don’t need to select a sampling option.
`You should, however, downsample your images when they contain more image data than your final
`output device can use. Higher image resolution is not always the better choice when you're working with
`images. If your printing device can’t use the information, the extra resolution only increases the time it
`takes the printer to process the image. Smaller PDF files are easier to transmit, take less time to RIP, and
`less space to archive. To determine how much image information is appropriate for your printer (or how
`much the printer can use), follow the guidelines we include here. The downsampling resolution you
`calculate using these formulas is the dpi value you enter for the Downsample To option in the Job Options
`dialog box.
`Downsample a color or grayscale image to 1.5 to 2.0 times the line screen ruling at which it will be
`printed. (Images that contain no straight lines or geometric or repeating patterns won't be affected by a
`lower resolution.) This table includes common printer types and their resolution measured in dots per
`inch (dpi), their default screen ruling measured in lines per inch (lpi), and a downsampling resolution for
`color or grayscale images measured in pixels per inch (ppi):
`
`
`
`When working with monochrome images, downsample it so that the resolution matches that of the output
`device but doesn’t exceed 1500 ppi. (Saving a monochrome image at a resolution higher than 1500 ppi
`increases its file size, but not its printed quality.)
`
`I/Vhile compression decreases the file size of images and produces smaller PDF files, it may also cause an
`image’s quality to decrease. The ZIP compression method is lossless (that is, it doesn’t eliminate data to
`reduce the file size and thus doesn’t affect the image’s quality), while the ]PEG compression method is
`lossy (that is, it does eliminate image data and so may decrease the image’s quality). Because it’s eliminat-
`ing image data, IPEG compression achieves smaller file sizes than ZIP compression.
`The IPEG compression options range from low to high. Higher compression options create smaller files,
`but affect image quality. The compression methods for monochrome images included in Distiller are
`lossless, so these compressed images retain their quality.

`
`

`
`Note: The IPEG settings in Acrobat Distiller are the opposite of those in Adobe Photoshop'software—where
`IPEG High means “high quality” and IPEG Low means “low quality.”
`
`For color and grayscale images, Distiller includes automatic and manual compression options. If you
`select the Automatic Compression option, Distiller uses JPEG compression for images with smooth color
`changes and ZIP compression for images with sharp color changes. If you select the Manual Compression
`option, you can specify the compression method you want Distiller to use.

`

`Manual Compression:
`
`Compress Text and Line Art—Make sure the Compress Text And Line Art option is selected (it’s selected by
`default). The compression method Distiller uses for text and line art, such as vector EPS graphics, is lossless,
`so it doesn’t affect the quality of these elements in your PDF file.
`
`Color Bitmap Images—If you want Distiller to downsample color images, select the Downsample To option
`and specify the appropriate dpi value. If you enter a value as we have done (300 dpi), Distiller doesn’t
`downsample the image until its resolution exceeds two times the value specified here. If all your images
`contain the appropriate amount of image data and the images have not been scaled smaller, deselect the
`downsample option. For compression, we recommend using automatic compression method set to
`(ZIP/IPEG Low).
`
`Grayscale Bitmap Images—If you want Distiller to downsample grayscale images, select the Downsample To
`option and specify the appropriate dpi value. If you enter a value as we have clone (300 dpi), Distiller doesn’t
`downsample the image until its resolution exceeds two times the value specified here. If all your images
`contain the appropriate amount of image data and the images have not been scaled smaller, deselect the
`downsample option. For compression, we recommend using automatic compression method set to
`(ZIP/IPEG Low).
`
`Monochrome Bitmap Images——Select the downsample option and enter the resolution of the final output
`device. Then, select Manual Compression and choose CCITT Group 4 for the greatest compression.

`
`Font Embedding Options recommendations
`
`In the Font Embedding tab, you can specify which fonts you want embedded in the PDF file to prevent font
`substitution at print time. Distiller never embeds the ITC Zapf Dingbats‘ and Base 13 fonts (Helvetica',
`Times“, Courier, and Symbol font families) because these fonts are included in all PostScript devices. When
`you select the Subset Fonts Below option, Distiller embeds only the font characters (glyphs) used in the
`document and ensures your fonts and font metrics are used at print time. (Subsetting fonts may limit your
`ability to do late-stage editing. However, you can use the EnFocus PitStop plug—in version 1.5, to add font
`characters for late-stage editing as long as the font is installed in your system.) For details, visit the Adobe
`Web site at this URL: http://wwwpluginsource.com[.
`
`The value you enter for the Subset Fonts Below option determines the point at which Distiller will include
`the entire font. For example, if you specify Subset Fonts Below 25%, and more than 25% of a font’s charac-
`ters are used in the document, Distiller will embed the entire font. If you want to subset fonts whenever
`possible, enter a higher value.

`Embed All Fonts—Select this option to prevent font substitution at print time. (Distiller embeds all
`PostScript fonts used in the document and all TrueType fonts included in the PostScript file.) This option
`also enables Distiller to subset fonts.
`
`Subset Fonts Below-—-Select the Subset Fonts Below option and specify 99% so that Distiller is most likely to
`embed only the font characters used in the document. Distiller renames subsetted fonts in a PDF file to pre-
`vent an available font with the same name from being used at print time. For example, if you’ve subsetted an
`older version of the Adobe Garamond' font in your document because you like the looser font metrics for
`letter and word spacing, but your service provider’s PostScript RIP contains a newer version of the font with
`tighter font metrics, the subsetted font will always be used for viewing and printing.
`
`Renaming the Acrobat Distiller font database file
`
`In Acrobat Distiller 3.0x, font substitutions can be managed through use of a font database (Superatm.db for
`the Macintosh and Distsadb.dos for Windows). These files list the font descriptions for several thousand
`commercially available fonts. Acrobat Distiller uses the font database to construct a document font that is not
`available when distilling the PostScript file. For low-resolution printing, the Distiller font database is useful;
`however, we recommend renaming these files (disabling them) if you are creating PDF files for high-
`resolution printing. The Superatm.db file (Macintosh) is in the Acrobat 3.0 > Fonts folder. The Distsadb.dos
`file (Windows) is in the Acrobat3 >Distillr >
