Overprinting 95% K

[DCurry]

Let's say I want to overprint all black objects tinted at 95% or higher - how would I do that in Apogee?

[DigitalCrapShoveler]

Render-Trap in the Renderer Workflow, under Black Trapping.

[DCurry]

I thought so, but can't seem to make it work. I set it as low as 80% and it no worky.

[DigitalCrapShoveler]

Hmmm, Okay, tell me more about the originating file.

[DCurry]

Nothing fancy -- in fact, I am just doing this as a test for future reference. File created in InDesign; I've got a magenta box with an overlapping 95% black box and some type that is also colored to 95% K. No transparency being used. I know how to get it to work if I set overprints in InDesign but I'm trying to see how to make Apogee to all the overprinting because I know of a future job that it would be handy to do on.

Export as PDF, using APPE (PDF Render) in Apogee.

Hmmmm, are you turning the Black Swatches to Overprint off in your preferences within InDesign? If you are, than InDesign is making a knockout in the PDF. Apogee X will make the black OP, but because there is a knockout, it appears not to. When viewing your PDF within Acrobat, does the Black KO, or OP?

[DCurry]

I've got my ID prefs set to OP black at 100% (can't change the %). The PDF has the 95%K  knocking out which is what I would expect -- remember, I want Apogee to take care of the overprinting.

[DigitalCrapShoveler]

Yeah, but if the knock out is resident in the PDF, you see the problem? X won't appear to OP it, because it's already knocked out. You will need to set up a Trapping Pref within InDesign, apply it and then have Apogee X honor it.

Hmmm... pretty sure I've seen Prinergy do that as well.

[DigitalCrapShoveler]

It would. InDesign sets the precedent for how a file gets trapped initially, so the key is to make it mesh with your workflow. I take one job at a time, I like setting auto features, but trapping in the various apps is different, and need to be handled differently. Dan, maybe you would be better off setting up an action in Pitstop to set the 95% k to OP. InDesign will do it, but you need to attack it from the PDF level before it hits the RIP.

[DCurry]

Yes, I know all the possible workarounds for accomplishing this task before it gets to Apogee. I'm just really surprised that you can't do such a simple thing in Apogee that I could do on ancient workflows like my old PSM rip. Brisque can do it, Prinergy can (I think).

Maybe I'll experiment tomorrow with using PostScript and the CPSI Render to see if it behaves any differently.

I'll do some testing tomorrow and see if I can come up with a solution for you.

[DCurry]

Switched to Render instead of PDF Render (CPSI vs. APPE) and no matter what I change it won't do it. Even tried submitting PostScript.

Oh, well, another disappointment! I'll keep investigating. Thanks for the help anyway.
