problem with transparency Indesign

[TXPinky]

Problem I have since yesterday: If I put a free-standing image over a frame border and then create a PDF, the frame will be shown as a cut-out; you can see it disappear in acrobat, but a customer of mine printed it and the frame edge has been cut out everywhere where a logo or a free-standing image has been placed over it. We've both seen that for the first time since yesterday. He has an older version and I have the latest version.

A guess is that you used PDF/X1-a or some other flavor of Acrobat 4 compatibility or the customer is using something other than Acrobat. If that's not the case, please post the PDF.

What should I use instead? I always use PDF/X1, it always worked

I always use PDF/X1, it always worked

Are you viewing in AcrobatPro with Output Preview urned on?

Can you share the ID file and image?

[BobLevine]

A further guess now that you've confirmed that is that this time you used a spot color. When you do that, InDesign uses white set to overprint to handle the transparency flattening.

You will notice that the full preset is PDF/X1-a: 2001. 2001 is the year. This is an absolutely archaic method of PDF creation that has no support for transparency or color-managed RGB workflows.

should I use PDF/X4?

[TXPinky]

With PDF/X4 it is ok! Thanx!!!

It looks like a Blending Mode Effect getting rendered differently in the PDF reader, Check to see if there is a Blend Mode applied to any of the interacting objects.

It is solver it was caused by the Adobe PDF preset PDF/X-1 which one always worked until now ha ha I switched now to X-4

Rob, as I mentioned above, I'm betting it's a spot color that involved here.

No spot color used! Just cmyk border color and rgb png on top; I changed nothing like I use to do the last years, but yesterday it suddenly didn't work and one of my clients had the same issue yesterday; strange!

So there’s no transparency being applied? Is this an Export from CC2023? I’d be curious to see the file, that shouldn’t be happening.

[TXPinky]

I know that shouldn't be happening! But it did since yesterday! Don't know what is changed ha ha I am a real pro user so I know what I am talking about!

Only over that border or also if you place it above the text?

My guess would also be a blend mode in the image itself (Check in Illustrator)

Also try turning on 'Overprint Preview' in Indesign.

It is solved, it was the PDF/X1 Adobe preset, what always worked, but now I switched to a higher one
