Hi,

you should search for pstill : this tool can convert RGB PDF to CMYK ones, but it is not free.

For CMYK PDF with images, you must use CMYK images as input, so that FOP output the PDF already partially in CMYK. You can not actually produce CMYK pdf without using CMYK jpgs as input. I think that you should take a look at image magick for converting your images. This tool do pretty good RGB to CMYK conversion.

Hope this help

Hi olivier,

at first, you have nothing to do special to use CMYK jpg with FOP  0.20.5.  It should work the same as RGB jpg.

But you should know that FOP 0.20.5 as a bug with rgb color : if a  component is less that 12, it set it to 0. So that :

rgb(24, 12, 50) became rgb(24, 0, 50) inside PDF. Be aware of this  if you want perfect colors.

On my own, i've written a little java code that can replace RGB  colors by CMYK ones inside a PDF. You should find it at PDFBox  website. (PDFBox is a java library to manipulate PDF).

I'm currently using FOP 0.20.5 to produce CMYK PDF.

Thanks for your answer. I have already tested your code and it works  fine for texts elements. But do you import CMYK pictures on your  PDF ? If you don't, how produce CMYK PDF with RVB pictures ? That's  my last problem. We use FOP 0.91 maybe its a clue.

Someone was talking about free third part tools to convert RVB PDF to  CMYK PDF but I can't find one. An idea ?

Thank you
Olivier

Hey

We are evaluating fop solution to produce PDF with CMYK color- space use.
I have found a solution to convert RGB definition for text- element  (see : http://tinyurl.com/ewpxh) but when I import a CMJN  jpg I have  this error message :
"Invalid ICC profile: java.lang.IllegalArgumentException: Invalid  ICC  Profile Data java.lang.IllegalArgumentException: Invalid ICC  Profile  Data""

Is there any solution to have a PDF output with CMYK ?

Thanks a lot.
Olivier
