Hello Friedrich,
effects you are describing are so called overprint and trapping. Both can be specified directly by application (e.g. Adobe Illustrator), but in automated production it is better to delegate this step into RIP (if in-RIP trapping is available). It can even avoid possible mistakes, e.g. wrong setting for negative text. There are several workflows used in print production like Heidelberg Prinect, Agfa Apogee, Kodak/Creo Prinergy etc. which enable to 'normalize' source document, strip ICC profiles, correct line widths, and among these also discard any present trapping or create new one using sophisticated algorithms. It is very important to know used toolchain as your settings can be modified or totally ignored at the end.

Before I can respond, our development team would need to evaluate how difficult it is to do -- the first step in our requirements analysis. once they provide me with estimates to accomplish a specific task, I can schedule that into the development sequence. and of course, RenderX also balances this with customer need and even paid-for extension development.
Let me get estimates based on your requirement specification and I will get back to you.

Kevin:
Thanks a lot for your fast answer.
How can I increase the priority for my rx:overprinting extension?
I plan to create tens of thousands of high quality phone book advertisements (in PDF format) with renderx solution till end of this year.
I plan to spread this solution to many other european publishing houses.
Most of these ads have colored backgrounds.
With other words: Overprinting is a very important feature in my media world.
Why loosing the chance to conquer the european phone book advertising market this year?
Can you promise me the rx:overprint extension till end of this year?
Fritz

Betreff: RE: XSLFO and overprinting
Friedrich:
We can add that to the future requirements list. I am currently working on the list for the next version but I can say I'm pretty sure this will not make it. Currently I would like to target enhancements to the PDF Forms capabilities to support adding Javascript (for data validation and other actions) as well as expanding PDF capabilities to include embedding other forms of multi-media like Flash, MPEG, AVI, MP3. I have also requested an ability to add attachments to the PDF (like attaching an Excel spreadsheet).

Hi Kevin,
If you print on coloured backgrounds, normally the background-color is not printed on the areas directly underneath the text-characters.
This guarantees the foreground and background colours not to be mixed.
But in case, when a printing studio is not able to print the foreground colour exactly on the intended places, there are small gaps between the background-colour and the foreground-character, where you can see the paper shining through.
That's why my printing department wants me to force black text (and only black text) to overprint background colours.
How can I do this with XSLFO and RenderX?
As far as I know, there is no overprint-attribute in XSLFO-spec.
But as far as I know, there is a overprint attribute in the PDF-spec.
What do you think about a RenderX extension?
Kind regards
Friedrich Kirch
