Apparently Application Built-in Trapping has been disabled. Since version 16, printing to PDF/PS with this option has failed.

Either disable/remove it or show a pop-up message recommending In-Rip Trapping whenever a user accesses this option. Although I would like it left as an option (and working) since I see some untrapped printed items, which means either the printer doesn't do trapping, or doesn't know how.

Hello, wondering if any of you discovered what the issue is with this. I recently encountered this problem again. I have a legacy version of Indesign, CS3, which I typically use for plate output; but it's currently not available to me. The issue with the "Adobe IN-RIP separations" setting is that you have no control over how the trap engine functions. The Indesign application would allow you to select and adjust for colors/black, etc.

I spent 2 hours on the phone with Adobe support yesterday troubleshooting this issue. Interestingly, they did not automatically kick me out and tell me 'sorry, that feature no longer works'....they remotely checked a bunch of stuff on my computer, and then told me they'd take it back to the design group and get back to me in a day or two.

Apparently there is no solution. I've tried it with ID 2021, 2022, 2023. Which is why I've stayed with ID 2020. Rob Day was patient enough to work with me through the problem, but nothing worked. It can't be a Windows problem, because it still works with ID 2020. While I appreciate the suggestion by industry experts to leave the trapping to the printer, I have to have the option available should the need arise.

In-app trapping only supports ID up to version 16.0....

I output plates for some of my work using an HP laserjet 5000 printer with a postscript driver, and there is no 'trapping software'...

Hi @spaktacular and @packaging specialist , Have you tried outputting a postscript file and Distilling using the Adobe PDF 9.0 PPD? That still works for me with CC2024 on MacOS Ventura. The problem might be with the HP postscript driver and not InDesign?

Here in CC2024 with the InDesign default trap to a large .01" and Saved a .ps file using the Adobe PPD, and the InDesign built-in trapping—same as the test I posted from CC2021 2 years ago:

The distilled PDF in the latest AcrobatPro, where you can clearly see the trap:

@rob day Hello, it's me again, same old problem. First off, thank you for your patience. Seeing your last post creating the trap in InDesign2024 gives me hope. Two years ago you showed me output from v16+. However, nothing has worked for me. I've installed and tried printing to Adobe PDF 9.0 PPD. I've cleared out the caches and recovery files and everything. I don't think it's a Windows problem either, because it still works with InDesign v15.

Hi @edy54443724 , I’m still using 16.4 and don’t see the problem. You have to chose Separations:

Hi Rob,

Thank you for the reply.

I have tried choosing Separations and In-Rip Separations, tried printing to PS and PDF, tried the Adobe PDF 9 PPD suggested elsewhere in the forum, and none worked. I get the message "Adobe has failed to print/output your data..."

The last time it worked for me was version 15 (2020). It didn't work with v16.4, v17.4, and v18.0. It can't be my setup, because it didn't work either on somebody else's computer, running v17. I'm surprised that it worked for you on v16.4.

Which is why it got me to thinking Adobe had disabled Application Built-in Trapping.

My thanks too, to Eugene Tyson for his input.

I have Separations and Application Built-In selected. Are you trying to output Separation plates, which is what I’m showing, or a composite page with traps?

Hello @edy54443724

Complex query this hour of the morning (for me anyway)

There's some documentation here if you have not already seen this

https://helpx.adobe.com/ie/acrobat/using/trapping-color-acrobat-pro.html

In my almost 25 years experience, I have worked in screen printing, as a lithographic prepress operator, graphic designer, and artwork specialist.

Trap settings are usually a requirement of the prepress processing of the document.

I assume Adobe have left Trap settings optional for export directly from the application - or applying custom trap settings in Acrobat for specific reasons.

But it's certainly something I've adjusted for when screen printing, definitely something I would adjust/fix in prepress - and definitely not something I've done in the last 15 years as a designer/artwork specialist.

Unfortunately, I may be behind the curve on Trap settings and how they are applied in modern or archaic workflows.

@rob day is very good with colour and things of this nature - perhaps can chime in with technical observations. As I'm sure many of the Community Experts involved here can.
