Hello everyone, I'm about creating a DIN Lang Folder brochure with ConTEXt. I got everything set up the way I'd like it to. Now that I'm done with the work, I've been told the output pdf should have a CMYK Color profile embedded for the on demand printing service to be able to deal with the file... I am unsure what steps I have to take to make my output pdf compliant with CMYK. I don't even know how I could verify it does indeed have CMYK. Evince doesn't seem to show that info... So if anybdy of you could give me some hints, that's be wonderful. Cheers De Benny

Hi Benny, if you can read German you might find some hints in my articles about creating din lang folders https://www.hasecke.eu/post/werbemittel-mit-context-gestalten/ On colors read the second part: https://www.hasecke.eu/post/wie-wir-bei-hostsharing-mit-context-arbeiten/ Search the mailing list for color profile questions because I had to ask often to make my things work. ;-) The wiki contains some hints, too. What you can do is to create a mode like this: \startmode[fogra39] \doiffileelse{CoatedFOGRA39.icc}{}{\farbprofilnichtgefunden} % This will be printed in log if context does not find the profile for % some reason \definecolor [hs-logoblau] [c=1.000, m=0.735, y=0.279, k=0.160] \definecolor [hs-dunkelblau] [c=0.844, m=0.544, y=0.070, k=0.000] \definecolor [hs-hellblau] [c=0.468, m=0.220, y=0.086, k=0.002] \definecolor [hs-orange] [c=0.127, m=0.832, y=1.000, k=0.042] \setupcolors[cmyk=yes,rgb=no,] \setupbackend[ format=PDF/X-3:2003, intent={Coated FOGRA39 (ISO 12647-2:2004)}, ] \stopmode If you call context with --mode=fogra39 you will get these color definitions and the defined pdf format with the right profile (intent). If you download additional icc profiles (eg. the fogra one is missing in the context distribution) put them here: context/tex/texmf-local/colors/icc In this folder they won't be overwritten by an update. There are some limitations in ConTeXt concerning colors as embedded images are not converted, so RGB images are converted only by the print shop during printing, which can lead to strange results. I think the only way to control the output is to convert all images to CMYK by hand. By doing this you can modify them to get the best results. I hope that helps juh

makes sense what you write, but as I am not sure about the whole issue, I won't bet. ;)

Hi Jan,
yes, I've read these texts once and they played a role in thinking about getting into ConTEXt.
Thank you for your answer, now I have something to investigate.
Another follow up question on background colors:
I try to setup the background color by
\setupbackgrounds[page][backgroundcolor=blue]
This works for the actual flyer, but the bleed remains white.
I also tried replacing 'page' with 'paper', but then the whole document has white background...
I saw your Hostsharing flyers do also have colors/graphics reaching the edge of the flyer, so I figure you ran into the same problem once.
Thanks a lot
De Benny

Here's the example. It's basically the code from DIN Lang Folder in the Wiki plus a setupbackgrounds command. It works with `page` but fails to work with `paper`: %% This is a template for a Din lang Folder. %% The folded page of such a flyer is shorter (97mm) than the other pages (100mm) %% This measure shows how much shorter the folded page is. \definemeasure [shortfold] [3mm] %% The bleed measure is necessary if you have colored page backgrounds %% or images in the bleed. %% Different print shops need different bleeds. \definemeasure [bleed] [1mm] %% This is the pagesize of the final PDF. %% The bleed size is added two times to width and height. \definepapersize [A4-flyer] [width=\dimexpr297mm+2\measured{bleed}\relax, height=\dimexpr210mm+2\measured{bleed}\relax] %% The size of a normal page. \definepapersize [flyer-page] [width=100mm, height=210mm] %% The size of the folded page. \definepapersize [flyer-page-small] [width=\dimexpr100mm-\measure{shortfold}\relax, height=210mm] %% Imposition: With the following two commands we arrange the six pages %% on the final PDF print sheet. %% The flyerpages are imposed on the printed sheet. \setuppapersize [flyer-page] [A4-flyer] %% The pages are arranged as a tryptichon. \setuparranging [TRYPTICHON] %% Because of the shorter folded page and the bleed the pages has %% to be shifted horizontally on the printed sheet. %% The values are calculated here. \definepageshift [flyer] [horizontal] [\dimexpr\measure{bleed}-\measured{shortfold}\relax, \measure{bleed}, \measure{bleed}, \dimexpr2\measured{shortfold}+\measured{bleed}\relax, \measure{bleed}, \dimexpr\measure{bleed}-\measured{shortfold}\relax ] %% The vertical pageshift is simple. \definepageshift [flyer] [vertical] [\measure{bleed}] \setuppageshift [paper] [flyer] %% We define some measures to construct the page layout. \definemeasure [small] [3mm] \definemeasure [big] [\measure{small}*2] %% Each page has a slightly different page layout. %% The named layouts (1. bracket) inherit values from other layouts %% which are assigned in the second bracket. \definelayout [first] [page] [page=flyer-page, topspace=2\measured{big}, backspace=2\measured{small}, width=\dimexpr\paperwidth-4\measured{small}\relax, height=\dimexpr\paperheight-4\measured{big}\relax] \definelayout [second] [first] [topspace=2\measured{big}, backspace=2\measured{small}, width=\dimexpr\paperwidth-2\measured{big}\relax] \definelayout [thirdandfourth] [second] [backspace=\measure{big}, width=\dimexpr\paperwidth-2\measured{big}\relax] \definelayout [fifthandsixth] [first] [backspace=\measure{big}, width=\dimexpr\paperwidth-2\measured{big}\relax] %% We assign the layouts to the pages. \definelayout [1] [first] \definelayout [2] [second] \definelayout [3] [thirdandfourth] \definelayout [4] [thirdandfourth] \definelayout [5] [fifthandsixth] \definelayout [6] [fifthandsixth] %% Some setups \setupmakeup [doublesided=no] \setuptolerance [verytolerant] %% We want to see page and layout borders. %% COMMENT THIS OUT BEFORE YOU PRINT! \showframe \setupbackgrounds[paper][background=color,backgroundcolor=blue] \starttext \starttitle[title={First page}] \input lorem \stoptitle \starttitle[title={Second page}] \input lorem \stoptitle \starttitle[title={Third page}] \input lorem \stoptitle \starttitle[title={Fourth page}] \setuppapersize [flyer-page-small] [A4-flyer] \input lorem \stoptitle \starttitle[title={Fifth page}] \input lorem \stoptitle \starttitle[title={Sixth page}] \setuppapersize [flyer-page] [A4-flyer] \input lorem \stoptitle \stoptext
When stupidity strikes, no one's safe. Turns out \setupbackgrounds has an option called backgroundoffset, and this is the solution. The not colorized part was the bleed part of the document, so the background command would be: \setupbackgrounds [paper] [ background=color, backgroundcolor=blue, backgroundoffset=\measured{bleed} ] wonder if this would be handy in the DIN lang folder template in the wiki, as most such brochures will supposingly have a colored background...?
