any prepress gurus out there that can with this one?

I seldom get this stuck on outputting a job, but i just cant figure it out.

i have a customer supplied indesign file, its an annual report, and there are several pages with grayscale photoshop files with black text on top.

when sending it to my RIP the black text is trapping into the grayscale image - making it look terrible, and even filling in.
ive tried several things, transparency flattener settings, manually telling black to overprint, changing the file type of the image, nothing is working.

ive never seen black trap into black!

Any suggestions???

Something is going screwy in the rip (which isn't uncommon).

My first course of action would be to eliminate any new variables and go with what has always worked. Maybe change the PSDs to Jpegs or tiffs or something and do a test run. If that clears it up, I'd then contact the RIP manufacturer and tell them about it.

Hope this helps.

Make sure the grayscale images are truly grayscale and not RGB. Next, make sure the color profile for the document is properly set up. And finally, you can try making the black type 99% black - this will force InDesign to flatten the type and image together, but at 99% it will still appear 100% black when printed.

Just check these images are right grayscale
Convert them in to tiff
Check in the RIP options Black overprint option ON..
or
type the text again in Idesign..delete from the images...

Did they create the indd document in an older version of InDesign? Maybe there's just something weird when it opens up in a newer version of InDesign if it was created in an older version. Or vice versa.

You never know.

I even created a test document, with several grayscale file types from photoshop, and placed black text on top of them in indesign, the same thing happens every time. if i turn of trapping in the RIP it doesnt trap, but it is still a two color job and there needs to be trap where it SHOULD be, on the SPOT colors!

if and when i find a solution... i will post it

Put the text in the photoshop files and create flattened CMYK tif files. Make sure the black is 100%K with no other colors. Then you're only using the black plate to screen for gray and at 100% for black.

If that isn't palatable then make sure your ID text is 100%K, not Registration or 100% of C,M,Y and K and export to PDF/X-1a from ID.

That is about the time i just tell the client it's something wrong with their files. :x

life is great; without it, you'd be dead.

so i did, and the client said "just change it to the pantone color, then the trap will be fine"

*sigh*
