Acrobat Pro 7 won't output a trapped PDF using the same method and settings as Indesign.
Both programs identical trap preset dialog and option to print to Adobe PDF with settings for Color: "In-Rip Seps" and Trapping: "Adobe Built-in".
Indesign outputs a nice trapped trapped file with these setting but Acrobat Pro does not.
In testing, same file(s) were attempted to be trapped from Acrobat Pro and Indesign. The reason to desire trapping in Acrobat is it is a one step process. Indesign won't trap placed PDF's so we use Illustrator to open them and copy and paste the objects into Indesign.
InDesign then traps beautifully.
Background- customer is a screen printer working with small spot color vector files requiring relatively large (.5pt - 2pt.) overlap between adjacent colors. In the past, they have manually applied traps in the illustration program rather than employ a trapping solution do to simplicity of much of our output and the control it gives us. Of course, when the file with 1,500 object arrives, they need another way to go - which is to use the Adobe trapping.
Please advise - is this simply a fact, or is there some update upgrade or some hard to find setting the customer is missing ?
Personally I've never tried generating a trap via Acrobat but I can indeed see the requirement. I'm sure this will only work when outputting a postscript stream down to an output device and not Distiller but I could be wrong.
I'm not even around a RIP at the moment (not even an AGFA one [smile]) so I can't check unfortunately.
