Dear List, A lot of you guys helped me through the process of setting a little booklet and I have to say I was proud of the result (44 full color pages with a lot of pictures and texts). Thanks for that. I'm now in the process of printing that booklet. I was happy to send my beautiful pdf to the printer for 250 copies, pdf file that has been refused because not in a PDF/X-1A format. I googled a bit and learned a bit about that: wikipedia has a good article [0] on the topic and there is LaTeX package (pdfx) for pdfTeX that has a good doc about that [1]. In short, PDF/X-1A is a set of rules and subset of PDF that ensures that the document will be see exactly the same for the editor and the printer (embed every fonts, use only CMYK and son on). Here is my question: is it possible to produce such documents with ConTeXt? It is quite frustrating to provide my printer with huge jpeg files. Thanks for the reply, -AJ [0] http://en.wikipedia.org/wiki/PDF/X [1] http://gentoo.chem.wisc.edu/tex-archive/macros/latex/contrib/pdfx/pdfx.pdf

the pdf code produced by pdftex/luatex is rather stupid in the sense that it is rather compliant you can control color to some extend using settings like \setupcolors[rgb=no] also, you can avoid interactive features what does the pdf validator of acrobat say? maybe the printer is bit picky on aspects that don't really matter (like having some specific key in a dictionary telling thisorthat) ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

The OP should also control the color model (cmyk) and the size/resolution of every picture included. These points are often causes of errors. -- Sébastien http://edilibre.net

And what exactly should I check that is related with the size / resolution of the pictures I included in the document? By the way, is there any way to check PDF/X-1A compatibility without a proprietary tool? All the best, -AJ
By the way, is there any way to check PDF/X-1A compatibility without a proprietary tool? AFIK none. BTW pitstop and adobe are the most important players in this area, so a certificate made from pitstop/adobe has more credibility than that one make from an open source tool

I'm not sure that simple is a synonym of complient in that case...

\setupcolors[rgb=no]
Okay I did it but it is still not accepted by my printer (with no other details than 'not pdf/x-a1...').
what does the pdf validator of acrobat say? maybe the printer is bit picky on aspects that don't really matter (like having some specific key in a dictionary telling thisorthat)
I have sadly no such tool. And I can't give the pdf to the world because of some information that it contains... (adresses and phone numbers of kids). I'll povide them with jpg. But that's not really cool. A+ -AJ

just ask him for a printed report; validators can do that Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Example command is: gs -dPDFX -dBATCH -dNOPAUSE -dNOOUTERSAVE -dUseCIEColor -sDEVICE=pdfwrite -sOutputFile=out-x3.pdf PDFX_def.ps input.ps If I understood it correctly, one can also replace "input.ps" by "input.pdf". (Note: Completely untested.) Tobias

Maybe you could use this shareware programm: http://www.pstill.com/ Info from this site: \startquotation "Convert to PDF, PDF/X and PDF/A Easy and high-quality EPS, PS, PDF and several raster image formats to PDF conversion _on Windows and MacOS X_, able to concat multiple files of all types in the output, also as mixed set. You can just drop in some PS, PDF and e.g. JPEG files and PStill will create one PDF from the input set. PStill can output also to PDF/X-1a and PDF/X-3, a focused subset of PDF for 'pre-press' work. PStill knows about CMYK and spot colors and can handle overprinting. Starting with version 1.72.18 PStill also creates PDF/A-1b, a special version of PDF for archiving purposes." \stopquotation \startquotation "The Linux, FreeBSD, Solaris, IRIX, AIX and HPUX versions are free only for personal/private and educational use. Commercial users (means: any for-profit use) must register and order a commercial type license key. The software will run without any functional restrictions but will display a notice on the console." \stopquotation From the above the impression could be raised that conversion to PDF/X-1a only works on Windows and MacOS X, but according to this post it seems to work on linux as well (?): http://www.stone.com/stoneforum/viewtopic.php?t=171 Note: Completely untested by me. Please inform us if it worked. You could also try one of these more commercial services: http://www.pdfxreport.com/doku.php?id=en:tools Thanks, Adriaan.
