The Adobe PDF Settings page shows the conversion settingsthat you can specify for your sources to use. You can use any ofthe predefined PDF settings or create your own. The PDF settingsdetermine precisely how files are converted and their resultantPDF structure and features. Adobe PDF settings were previously known asDistiller® parameters or job options.

On the Adobe PDF Settings page, you can do the following tasks:

View the predefined PDF settings. (See About the predefined PDF settings.)
Create a PDF setting or edit one that you created previously. (See Add or edit PDF settings.)
Specify default PDF settings. (See Change the default settings)
Upload a PDF settings file to the server. (See Upload PDF settings.)
Delete customized PDF settings. (See Delete PDF settings.)
Upload and download prologue and epilogue files. (See Uploading and downloading prologue and epilogue files.)

Adobe PDF settings are applicable only to the PDFMaker basedconversions. These include the following conversions:

Microsoft Word document (DOC, DOCX, RTF, TXT)
Microsoft Excel document (XLS, XLSX)
Microsoft PowerPoint document (PPT, PPTX)
Microsoft Project document (MPP)
Microsoft Visio document (VSD)

Note:

On using OpenOffice to convert above formats, Adobe PDF settingsare not applied.

PDF Generator provides several predefined PDF settingsfor your use. You cannot modify these predefined settings; however,you can create a setting based on an existing one by editing thesetting and saving it under a new name.

Creates PDF files for high-quality output. This setting:

downsamples color and grayscale images at 300 dpi
downsamples monochrome images at 1200 dpi
prints to a higher image resolution
uses other settings to preserve the maximum amount of informationabout the original document.

These PDF files canbe opened in Adobe Acrobat 5 and Adobe AcrobatReader® 5 or later.

Creates PDF documents that are suitable for reliable viewing andprinting of engineering drawings that are larger than 200 x 200inches. Created PDF documents can be opened in Adobe Acrobat Professionaland Acrobat Standard, version 7 or later, and Adobe Reader 7 orlater.

Checks incoming jobs for compliance to the ISO standard for long-term preservation (archival) of electronic documents and creates PDF/A files only if compliant. These files are primarily used for archiving. Compliant files can contain only text, raster images, and vector objects; they cannot contain encryption and scripts. In addition, all fonts must be embedded so that the documents can be opened and viewed as created. PDF/A-1b uses PDF 1.4 and converts all colors to either CMYK or RGB, depending on which standard you choose. PDF files that are created with this settings file can be opened in Acrobat 5 and Acrobat Reader 5 and later. For more information about PDF/A, see Adobe and industry standards.

Checks incoming jobs for PDF/X-1a compliance, and creates PDF files only if compliant. PDF/X-1a is an ISO standard for graphic content exchange. PDF/X-1a requires all fonts to be embedded, the appropriate PDF boxes to be specified, and color to appear as either CMYK or spot colors. PDF files that meet PDF/X-1a requirements are targeted to a specific output condition, such as web offset printing according to Specifications Web Offset Publications. For more information about PDF/X, see Adobe and industry standards.

Checks incoming jobs for PDF/X-3 compliance and creates PDF filesonly if compliant. Like PDF/X-1a, PDF/X-3 is an ISO standard forgraphic content exchange. The main difference is that PDF/X-3 supportsdevice-independent color.

Creates PDF files for high-quality print production (forexample, on an imagesetter or platesetter). In this case, file sizeis not a consideration. The objective is to maintain all the informationin a PDF file that a commercial printer or prepress service providerneeds to print the document correctly. This set of options:

downsamples color and grayscale images at 300 dpi
downsamples monochrome images at 1200 dpi
embeds subsets of all fonts used in the document
prints to a higher image resolution,
does not automatically rotate pages based on the orientationof the text or document structuring conventions (DSC) comments
uses other settings to preserve the maximum amount of informationabout the original document.

Print jobs fail ifthey have fonts that cannot be embedded. These PDF files can be openedin Acrobat 5 and Acrobat Reader 5 and later.

Note: Beforeyou create a PDF file to send to a commercial printer or prepressservice provider, determine the output resolution and other settings,or request a .joboptions file with the recommended settings. Youmay need to customize the Adobe PDF settings for a particular providerand then provide a .joboptions file of your own.

Creates PDF files for displaying on the web or an intranet,or for distribution through an email system for onscreen viewing.This set of options uses compression, downsampling, and a relativelylow image resolution. It converts all colors to sRGB and does notembed fonts unless necessary. It also optimizes files for byte serving.These PDF files can be opened in Acrobat 5 and Acrobat Reader 5.0and later.

Creates PDF files to print to desktop printers or digitalcopiers, publish on a CD, or send to a client as a publishing proof.This set of options uses compression and downsampling to reducethe file size. It also embeds subsets of all fonts that are usedin the file, converts all colors to sRGB, and prints to a mediumresolution to create a reasonably accurate rendition of the original document.Notice that Microsoft Windows font subsetsare not embedded by default. These PDF files can be opened in Acrobat5 and Acrobat Reader 5.0 and later.

PDF settings determine precisely how files are convertedand their resultant PDF structure and features. Define a new PDFsetting or edit one that you created previously. You cannot modifypredefined settings, but you can create a setting based on an existingone by editing the setting and saving it under a new name.

In administration console, click Services > PDF Generator> Adobe PDF Settings.

Either click New or click the name of an existing setting.

On the New/Edit Adobe PDF Setting page, complete the requiredinformation in these sections:

To go to another section, click its linkon the web page or use the Next and Previous buttons.

After you complete the information in all sections, clickSave or Save As and provide a name for the setting.

You can have PDF settings available on the PDF Generatorserver by uploading them from a local computer or a network location.

In administration console, click Services > PDF Generator> Adobe PDF Settings, and click Upload.

On the Upload Adobe PDF Setting page, click Browse, locatethe PDF settings file, and click Open.

You can permanently delete PDF settings if they are nolonger required.

In administration console, click Services > PDF Generator> Adobe PDF Settings.

Select the check box beside the setting to delete. You canselect multiple settings.

Click Delete and, on the Delete Confirmation page, clickDelete again.

Use the general options to specify the version of Acrobatto use for file compatibility and other file and device options.For instructions about accessing the General options, see Addor edit PDF settings.

The compatibility level of the PDF file. For documents that will be widely distributed, consider selecting Acrobat 4 (PDF 1.3) or Acrobat 5 (PDF 1.4) to ensure that all users can view and print the document. If you create files by using Acrobat 5 compatibility or later, they may not be compatible with earlier versions of Acrobat. The following subsections show some of the differences between PDF files that are created using different levels of Acrobat compatibility.

Adobe Reader Dc Registry Settings

Consolidates small objects (each of which are not compressibleitself) into streams that can then be efficiently compressed.

Does not compress any structural information in the PDF document. Selectthis option if you want users to view, navigate, and interact with bookmarksand other structural information by using Acrobat 5 and later.

Compresses structural information in the PDF document. Usingthis option results in a PDF file that can be opened and printedby using Acrobat 5. Users cannot view any accessibility, structure,or tagged PDF information in Acrobat 5 or Acrobat Reader 5.0, butthey can view this information in Acrobat 6 and Adobe Reader 6.0.

Sets the automatic rotation of pages based on the orientationof the text or DSC comments. For example, some pages (such as pagesthat contain tables) may require the user to turn them sidewaysto read them. Select Individually to rotate each page based on thedirection of the text on that page. Select Collectively By Fileto rotate all pages in the document based on the orientation ofmost text.

Note: If Process DSC Comments is selectedin the Advanced settings and if %%Viewing Orientation comments areincluded, these comments take precedence in determining page orientation.

Specifies whether to display a PDF file with left-side orright-side binding. This setting affects the display of pages inthe Facing Page - Continuous layout and the display of thumbnailsside by side.

Sets the emulation for the resolution of a printer for inputfiles that adjust their behavior according to the resolution ofthe printer they are printing to. For most input files, a higherresolution setting results in larger but higher-quality PDF files,and a lower setting results in smaller but lower-quality PDF files. Mostcommonly, resolution determines the number of steps in a gradientor blend. You can enter a value from 72 to 4000. Keep this settingas the default unless you plan to print the PDF file to a specificprinter and you want to emulate the resolution defined in the originalinput file.

Note: Increasing the resolution settingincreases file size and may slightly increase the time requiredto process some files.

Specifies which pages to convert. Leave the To box emptyto create a range from the page number you enter in the From boxto the end of the file.

Restructures the file for page-at-a-time downloading (byteserving) from web servers. This option compresses text and lineart, regardless of what you selected as compression settings onthe Images tab. Compression results in faster access and viewingwhen downloading the file from the web or a network. By default,this option is not enabled.

The Default Page Size options specify the page size touse when one is not specified in the original file. Typically, AdobePostScript files include this information,except for Encapsulated PostScript (EPS) files, which give a boundingbox size but not a page size. The maximum page size allowed is 15,000,000inches (31,800,000 cm) in either direction. These options configurethe default page size:

Width of the page

Height of the page

Units to use for the width and height settings

The Images options specify compression and resampling forimages. You can experiment with these options to find an appropriatebalance between file size and image quality. For instructions aboutaccessing the Images settings, see Add oredit PDF settings.

These options configure color, grayscale, and monochrome images:

Set a value for each type of image. To downsample color, grayscale,or monochrome images, PDF Generator combines pixels in a sample areato make one larger pixel. Provide the resolution of your outputdevice in dots per inch (dpi) and enter a resolution in dpi in theFor Images Above box. For images with a resolution abovethis threshold, PDF Generator combines pixels, as needed, to reducethe resolution of the image (pixels per inch) to the specified dpisetting. To turn off downsampling, select Off. Here are the options:

Averages the pixels in a sample area and replaces the entirearea with the average pixel color at the specified resolution.

Uses a weighted average to determine pixel color and usuallyyields better results than the simple averaging method of downsampling.Bicubic is the slowest but most precise method and results in the smoothesttonal gradations.

Selects a pixel in the center of the sample area and replaces the entire area with that pixel at the specified resolution. Subsampling significantly reduces the conversion time compared to downsampling, but it results in images that are less smooth and continuous.

The resolution setting for color and grayscale should be 1.5 to 2 times the line screen ruling that the file will be printed at. (Providing you do not go below this recommended resolution setting, images that contain no straight lines, or geometric or repeating patterns, are not affected by a lower resolution.) The resolution for monochrome images should be the same as the output device. However, be aware that saving a monochrome image at a resolution higher than 1500 dpi increases the file size without noticeably improving image quality.

Also consider whether users need to magnify a page. For example, if you are creating a PDF document of a map, consider using a higher image resolution so that users can zoom in on the map.

Note: Resampling monochrome images can have unexpected viewing results, such as no image display. If this problem occurs, turn off resampling and convert the file again. This problem is most likely to occur with subsampling and least likely to occur with bicubic downsampling.

This table shows contains types of printers and their resolution measured in dpi, their default screen ruling measured in lines per inch (lpi), and a resampling resolution for images that are measured in pixels per inch (ppi). For example, to print to a 600-dpi laser printer, enter 170 for the resolution to resample images at.

Printer resolution	Default line screen	Image resolution
300 dpi (laser printer)	60 lpi	120 ppi
600 dpi (laser printer)	85 lpi	170 ppi
1200 dpi (imagesetter)	120 lpi	240 ppi
2400 dpi (imagesetter)	150 lpi	300 ppi

Set a value to apply to color, grayscale, and monochromeimages. For color and grayscale images, also set the image quality:

For color or grayscale images, select ZIP to apply compressionthat works well on images that have large areas of single colorsor repeating patterns. Examples are screen shots, simple imagescreated with paint programs, and monochrome images that containrepeating patterns. Select JPEG, quality minimum to maximum, toapply compression that is suitable for grayscale or color images,such as continuous-tone photographs that contain more detail thancan be reproduced on the screen or in print. Select Automatic (JPEG)to automatically determine the best quality for color and grayscaleimages.
For monochrome images, select CCITT Group 4, CCITT Group3, ZIP, JPEG200, Automatic (JPEG2000), or Run Length compression.

Makesure that monochrome images are scanned as monochrome and not as grayscale.Scanned text is sometimes saved as grayscale images by default. Grayscaletext that is compressed with the JPEG compression method is notclear and may be unreadable.

Configures the image quality for color and grayscale images. Theoptions are minimum, low, medium, high, and maximum.

Smooths jagged edges in monochrome images. Select 2 bit, 4bit, or 8 bit to specify 4, 16, or 256 levels of gray. (Anti-aliasingmay blur small type or thin lines.)

Note: Compressionof text and line art is always on.

Set a policy for color, grayscale, and monochrome images.If the image resolution falls below the specified resolution, youcan still select to proceed (Ignore), provide a warning message,or cancel the job.

The Fonts options specify which fonts to embed in a PDFfile and whether to embed a subset of characters that are used inthe PDF file. For instructions about accessing the Fonts options,see Addor edit PDF settings.

Note:

When you combine PDF files with the same fontsubset, PDF Generator attempts to combine the font subsets.

Embeds all fonts that are used in the file. Font embeddingis required for PDF/X compliance.

Subset Embedded Fonts When Percent Of Characters UsedIs Less Than:

If you select this option, specify a threshold percentageto embed only a subset of the fonts. For example, if the thresholdis 35 and less than 35% of the characters are used, PDF Generatorembeds only those characters. Only fonts with appropriate permissionbits are embedded.

Specifies how PDF Generator responds if it cannot find afont to embed when processing a file. You can have PDF Generatorignore the request and substitute the font, warn you and substitutethe font, or cancel processing of the current job.

The location of the fonts that PDF Generator uses.

In administration console, click Services >PDF Generator > Adobe PDF Settings.

From the Font source list, select a font source and clickGo to refresh the list of fonts in the box on the left.

Click a font in the box on the left. Then click Add besidethe appropriate box to move it to the Always Embed list or NeverEmbed list. Repeat for each font. Use Ctrl-click to select multiplefonts to move.

To remove a font from the Always Embed or Never Embed list,select it and click Remove beside the appropriate box. This actiondoes not remove the font from your system; it just removes the referenceto it in the list.

If the font you want to specify does not appear, type itsname in the Add Font box, and then click Always Embed or Never Embed.Font names cannot contain alphanumeric characters.

Note:

A TrueType font can contain a setting that thefont designer added that prevents the font from being embedded inPDF files.

Note:

Fonts are picked from the Windows system font cache and asystem restart is required to update the cache. After specifyingthe Customer font directory, ensure that you restart the systemon which AEM forms is installed.

The Color options set all color management informationfor PDF Generator. For instructions about accessing the Color options,see Addor edit PDF settings.

This list contains a list of color settings that are alsoused in major graphics applications, such as Adobe Photoshop andAdobe Illustrator. The color setting you select determines the otherAdobe color settings on this page. For example, if you select asetting other than None, all options other than those for Device-DependentData are predefined and dimmed. You can edit the Color ManagementPolicies and Working Spaces settings only if you select None for SettingsFile.

If you selected None for the Settings File, the Color ManagementPolicies area specifies how PDF Generator converts unmanaged colorin a PostScript file.

Leaves device-dependent colors unchanged and preserves device-independentcolors as the nearest possible equivalent in PDF. This option isuseful to print shops that have calibrated all their devices, usedthat information to specify color in the file, and output only tothose devices.

Embeds an International Color Consortium profile when distillingfiles and calibrates color in the images, which makes colors inthe resultant PDF files device-independent if you selected Acrobat4 (PDF 1.3) or later compatibility. However, device-dependent color spacesin files (RGB, Grayscale, and CMYK) are converted to device-independent colorspaces (CalRGB, CalGray, and LAB).

Embeds ICC profiles only in images, not text or graphics,when distilling files if you selected Acrobat 4 (PDF 1.3) compatibility.This option prevents black text from undergoing any color shift. However,device-dependent color spaces in images (RGB, Grayscale, and CMYK) areconverted to device-independent color spaces (CalRGB, CalGray, andLAB). Text and graphics are not converted.

Convert All Colors to sRGB or Convert All Colors toCMYK:

Calibrates color in the file, making the color device-independent,similar to Tag Everything for Color Management. If you selectedAcrobat 4 (PDF 1.3) or later compatibility and convert to sRGB,the CMYK and RGB images are converted to sRGB.

Regardlessof the compatibility option you select, grayscale images are left unchanged.This usually reduces the size and increases the display speed ofPDF files because less information is needed to describe RGB imagesthan to describe CMYK images. Because RGB is the native color spacethat is used on monitors, no color conversion is necessary duringdisplay, which contributes to fast online viewing. This option isrecommended if the PDF file is for use online or with low-resolutionprinters.

The method to map colors between color spaces. The resultof any particular method depends on the profiles of the color spaces.For example, some profiles produce identical results with different methods.These options are available:

Note: In all cases, intents may be ignored or overriddenby color management operations that occur after the creation ofthe PDF file.

Means that the intent is specified in the output device ratherthan in the PDF file. In many output devices, Relative Colorimetricis the default intent.

Maintains the relative color values among the original pixelsas they are mapped to the destination gamut. This method preservesthe visual relationship between colors, although the color valuesthemselves may change.

Maintains the relative saturation values of the originalpixels. This method is suitable for business graphics, where theexact relationship between colors is not as important as havingbright saturated colors.

Remaps the white point of the source space to the white pointof the destination space.

Disables the matching of white and black points when convertingcolors. This method is not recommended unless you must preserve signaturecolors, such as those used in trademarks or logos.

For all values in the list under Color Management Policies,other than Leave Color Unchanged, select from the lists in the WorkingSpace area to specify which ICC profiles are used for defining andcalibrating the grayscale, RGB, and CMYK color spaces in distilledPDF files. These options are available:

Defines the color space of all grayscale images in files.This option is available only if you chose Tag Everything for ColorManagement or Tag Only Images for Color Management. The defaultICC profile for gray images is Gray Gamma 2.2. You can also selectNone to prevent grayscale images from being converted.

Defines the color space of all RGB images in files. The default,sRGB IEC61966-2.1, is generally a good choice because it is becomingan industry standard and many output devices recognize it. You canalso select None to prevent RGB images from being converted.

Adobe reader preferences registry settings

Defines the color space of all CMYK images in files. Thedefault is U.S. Web Coated (SWOP) v2. You can also select None toprevent CMYK images from being converted.

Note: SelectingNone for all three of the working spaces has the same effect as selectingLeave Color Unchanged.

Preserve CMYK Values For Calibrated CMYK Color Spaces:

When selected, device-independent CMYK values are treatedas device-dependent (DeviceCMYK) values, device-independent colorspaces are discarded, and PDF/X-1a files use the Convert All ColorsTo CMYK value. When deselected, device-independent color spacesconvert to CMYK if the color management policy is set to ConvertAll Colors To CMYK.

These options apply if you work with documents that arecreated with high-end documentation and graphics applications, suchas Adobe Illustrator and Adobe InDesign. For more information, seethe documentation that came with the application.

Transfer functions are used for artistic effect and to adjustfor the specifications of a specific output device. For example,a file that is intended for output on a particular imagesetter maycontain transfer functions that compensate for the dot gain thatis inherent with that printer.

Preserve Under Color Removal And Black Generation:

Retains these settings if they exist in the PostScript file.Black generation calculates the amount of black to be used whenyou are trying to reproduce a particular color. Undercolor removal(UCR) reduces the amount of cyan, magenta, and yellow componentsto compensate for the amount of black that the black generationadded. Because it uses less ink, UCR is generally used for newsprintand uncoated stock.

Uploading and downloading prologueand epilogue files

Prologue files are used to add custom PostScript code thatexecute at the beginning of every PostScript job being distilled.Epilogue files are used to add custom PostScript code that executeat the end of every PostScript job. You can download prologue andepilogue files from the server to save them locally. You may wantto download the files to configure them independently or to upload themto another location or to another computer.

These files have many purposes. For example, prologue files canbe edited to specify cover pages; epilogue files can be edited toresolve a series of procedures in a PostScript file. You can alsoselect and upload the prologue and epilogue files to send with eachjob.

In administration console, click Services >PDF Generator > Adobe PDF Settings.

Click Advanced and then, beside the Use Prologue.ps and Epilogue.psoption, click Download.

On the Download Prologue and Epilogue Files page, click Prologue.psor Epilogue.ps and click Save.

In administration console, click Services >PDF Generator > Adobe PDF Settings.

Click Advanced and then, beside the Use Prologue.ps And Epilogue.psoption, click Upload.

On the Upload Prologue and Epilogue Files page, click Browseto select a prologue or an epilogue file.

To use the file, ensure that Use Prologue.ps And Epilogue.psis selected in the Advanced area of the New/Edit Adobe PDF Settingpage.

Note:

PDF Generator supports prologue and epiloguefiles only for conversion of PostScript and Encapsulated PostScriptfiles to PDF.
