Yet More PDF/PostScript Info. from Dov - Acrobat 5, 6, and 7
>I copied this FAQ from a Post Dov made to a particular thread in the FrameMaker forum. It answers several regularly asked questions and (hopefully) puts some myths to bed.
This thread has had a number of FrameMaker/Windows printing problems and issues raised. On behalf of Adobe, I'd like to a provide a summary to separate fact from bubbameisers and urban legend:
(1) There is a known bug in Microsoft Windows 2000 and XP associated with support for Multiple Master Type 1 fonts. See
Dov Isaacs "UPDATE (2003-01-31) README!!! Multiple Master Font Printing Problems under Updated Windows 2000 and Windows XP" 10/29/04 6:05am for a description of the problem and the fixes available. Hint: It involves getting your Windows 2000 and XP systems up to the latest service packs!
(2) There is a known problem with FrameMaker under Windows only in which text may disappear from the output page (i.e., selective text dropout) when printing to PostScript devices, including Acrobat Distiller. Unfortunately, the problem is NOT reproducible from system to system or document to document either user sites or within Adobe itself. What we do know is that the larger the logical page size in combination with higher resolution settings aggravates the problems (i.e., makes it more likely that you will actually see the symptom). It is for this reason that we most strongly recommend that you NEVER use a Windows PostScript printer driver setting higher than 600 dpi with FrameMaker. If necessary to print to a higher resolution device, create PDF first (with the Adobe Distiller / Adobe PDF PostScript printer driver instance set to no more than 600 dpi) and then do the final print from Acrobat / Adobe Reader to the actual print device. In the rare instances where there is still selective text dropout, set the driver resolution to 300 dpi. We know of no situations in which the selective text dropout persists at the 300 dpi setting. What are the ramifications of the lower resolution settings? The resolution of image data is not downsampled or degraded by this resolution setting. Nor is any damage done to vector graphics or the quality of text. What it does control for FrameMaker is the granularity of spacing, especially of text. Setting 600 dpi permits "only" 600 starting positions per inch and interword spacing in 1/600 inch increments. Images and vector graphics positioning is likewise limited to such increments. At 300 dpi, the value falls to 300 starting positions and 1/300 inch increments. Anything under 300 dpi is absolutely not recommended and could yield some rather gnarly text spacing. Again, we recommend you start at 600 dpi and stay with that if you have no problems. (Note also that 600 dpi gets around another Windows GDI bug in which text formatted in larger point sizes is converted to unhinted outlines. 600 dpi allow for text in pointsizes up to approximately 100 points to remain as text for printing purposes.)
(3) FrameMaker under Windows generates RGB PostScript via the Windows PostScript driver, based on GDI except for PostScript passed through from EPS (or PDF which is internally converted to EPS) placed in a FrameMaker document. There is NO standard method or available "plug-in" to get around this limitation and produce CMYK plus spot color PostScript. There are third party PostScript preprocessors and Acrobat plug-ins that can convert the RGB back to CMYK prior to or after distillation. Acrobat 7 Pro will provide you the facility to automatically convert RGB in your PostScript from FrameMaker or other GDI applications (such as Microsoft Office) to CMYK within the Distiller using ICC color management profiles.
(4) There is no such thing really as "Generic PostScript." PostScript as generated via the Windows PostScript driver is device dependent and specific. If you are generating PostScript for distillation, you should use the Acrobat Distiller (Acrobat 5) or Adobe PDF (Acrobat 6 and 7) PostScript printer driver instance generated by Acrobat when installed to print directly and automatically to the Distiller. In the worst case, you should be generating PostScript with a PostScript printer driver instance setup with the Acrobat Distiller PPD appropriate to the version of Distiller you are using. Otherwise, if you are printing PostScript "live" to a printer, you must use a PostScript printer driver instance configured with the PPD file specific to the device being printed to. That damnable "Generic PostScript" PPD in fact is for a brain-dead, PostScript Level 2, monochrome, 300 dpi device with limited page size definitions, no custom page size capability, large page margins, no TrueType support, etc. One of the largest sources of problems we encounter on this forum and on various e-mail lists I monitor are about problems with direct printing and/or PDF files generated using that $*&#(*$ "Generic PostScript" PPD. Make believe it doesn't exist.
