ghostscript

I am having much trouble to get ImageMagick's identify to, well, identify a PDF as CMYK. Essentially, let's say I'm building this file, test.tex , with pdflatex : \documentclass[a4paper,12pt]{article} %% https://tex.stackexchange.com/questions/13071 \pdfcompresslevel=0 %% http://compgroups.net/comp.text.tex/Making-a-cmyk-PDF %% ln -s /usr/share/color/icc/sRGB.icm . % \immediate\pdfobj stream attr{/N 4} file{sRGB.icm} % \pdfcatalog{% % /OutputIntents [ << % /Type /OutputIntent % /S/GTS_PDFA1 % /DestOutputProfile \the\pdflastobj\space 0 R % /OutputConditionIdentifier (sRGB IEC61966-2.1) % /Info

I need to use ghostscript for concatenating several PDFs into a single pdf file. The help I need from you is what command do I have to use, in order to edit the output page, so that it fits 4 pages of the input files, into 1 of the output. What I am using so far is this command: gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite \ -sOutputFile=ALL.pdf plot_1.pdf plot_n.pdf Input files are A4 landscape, and the output have to be the same format. Thanks to all, Cristian This is a program I wrote some time back to do 2-up imposition from PDF. This is not a general purpose PostScript program, it will only

I convert PDF -> many JPEG and many JPEG -> many PDF using ghostscript . I need to add watermark text on every converted JPEG (PDF) page. Is it possible using only Ghostscript and PostScript? The only way I found: gswin32c -q -sDEVICE=pdfwrite -dBATCH -dNOPAUSE -sOutputFile=output.pdf watermark.ps input.pdf But this will insert watermark.ps watermark on first separate page in output.pdf . Can I do this on output PDF pages directly? Can I do this on output JPEG pages directly? << /BeginPage { gsave /Helvetica_Bold 120 selectfont .85 setgray 130 70 moveto 50 rotate (Sample) show grestore } bind

I need to convert RGB PDF into CMYK PDF. I need to have pure black color for texts. It seems (thanks to comments below) term "black point compensation" is wrong. I took it from Adobe Acrobat where it works exactly how i need. I thought gs has same feature. I use ghostscript 9.16 If i got it right there is -dBlackPtComp option, but it does not work for me. Ghostscript command I have tried is: "c:/Program Files/gs/gs9.16/bin/GSWIN64C.EXE" -o testing_black_cmyk.pdf -sColorConversionStrategy=CMYK -sDEVICE=pdfwrite -dOverrideICC=true -sOutputICCProfile=c:/Windows/System32/spool/drivers/color

Background: I have PDF's I am programmatically generating. I need to be able to send the PDF directly to a printer from the server (not through an intermediate application). At the moment I can do all of the above (generate PDF, send to printer), but because the fonts aren't embedded in the PDF the printer is doing font substitution. Why the fonts aren't embedded when generated: I am creating PDF's using SQL Reporting Services 2008. There is a known issue with SQL Reporting Services in that it will not embed fonts (unless a series of requirements are met - http://technet.microsoft.com/en-us

Is it possible to write a script for Adobe Illustrator or some other tool that will read the contents of a number of PDF files and convert all the RGB colours to CMYK? If so, could somebody please point out some of the steps involved, or where to find more information on this? This answer is not for Illustrator, but for 'some other tool' , namely Ghostscript (download gs871w32.exe or gs871w64.exe ). Ghostscript allows you to 're-distill' PDFs ( without an intermediate conversion to PostScript, the dreaded 'refrying' detour). Try this command: gswin32c.exe ^ -o c:/path/to/output-cmyk.pdf ^

Is Ghostscript the best option if you want to optimize a PDF file and reduce the file size? I need to store alot of PDF files and therefore I need to optimize and reduce the file size as much as possible Does anyone have any experience with Ghostscript and/or other? command line exec('gs -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/screen -sOutputFile='.$file_new.' '.$file); Kurt Pfeifle If you looking for a Free (as in 'libre') Software, Ghostscript is surely your best choice. However, it is not always easy to use -- some of its (very powerful) processing
