Image edges leaking from placed Ill files?

[Scott.Olling]

So, I've placed Illustrator files into InDesign.

The boxes they're placed in have no fill/stroke/transparency. 

The Ill files have white backgrounds.

In ID there's no halo around the box - at first. Then they show up, and go away on restart, but then appear again.

I'm using my GPU performance display - these are set to Typical.

So, on the client's PC, these edges in their view of the Acrobat file are GIGANTIC as well as PERSISTENT.

What gives? meaning, why are they there? If I put a white stroke (1pt) on the box they go away.

What's the fix? How do I stop this cancer gnawing at the root of civilization etc.? I look forward to your collective, always sagacious, council - THANKS! -sno

Did you place the Illustrations using File>Place (the recommended method) or did you copy and paste them from Illustrator? If you placed them did you place them directly or did you import them into a graphic frame that you'd drawn in InDesign? If you did the former then try the latter method. In either case try selecting the frame and pulling in on the edges of it to eliminate the possibilty that the ghosting is actually coming in from the Illustrator files.

[Scott.Olling]

File>Place, however, the boxes are of different lineages. Some have had Placed files pasted from inside InDesign. I've also placed files over previous placed files.

They don't seem to follow a pattern. There should not be any image where the lines appear - there is no specification for the area.

What happens if you switch to High Quality Display? If you turn off GPU Performance?

[Scott.Olling]

going to Overprint Preview from Typical to Overprint Preview causes the lines to show. I get a spot color alert.

turning off Overprint Preview they go away.

going in the drop down from Typical to HQD the edges show. going back they go away.

now going to destroy all my spot colors and go again.

this is progress - great - but why do these lines show in the PDF? this is just display hijinks - is the PDF made from the GPU output? where's PostScript in this?

[Scott.Olling]

four spot colors converted

all in RGB space

made new PDF - result attached.

entertaining new conjectures - not sure where to go here. do I really put a white stroke on all these boxes? it's 2025 I've got my jetpak right here next to me

[Scott.Olling]

I guess I'll just put the white stroke on there - adding a specification for the unspecified area

takes me back to the days of white boxes before masking - ah, those heady days of the last century

any suggestions still welcome

Hi @Scott.Olling , Try setting your [Paper] or white stroke alignment to either Center or Outside

[Scott.Olling]

Thanks - I will if I have to - but I'll walk the streets with a cloud overhead

This has always happened—it’s a screen resolution artifact and should not show in high res print. The lines in my example do not print from my laser printer at 1200dpi. Setting a centered stroke alignment would be the safest approach

Also, Acrobat has more Page Display Rendering options than InDesign. Here’s what I get with Acrobat’s Enhance thin lines checked and unchecked

Remove the white background, make it transparent. 

[Scott.Olling]

unfortunately the white backgrounds are in Illustrator, and they're knocking out elements that are very complex to mask.

my boxes are set to no fill no stroke
