White shapes in InDesign used to cover arrow edges are visible in the PDF

Hi, I’m having an issue with white areas appearing between the arrows. These are just standard white shapes, but they remain visible in PDF/X-4 and "small size" PDF files. I’ve tried various methods to remove them, but nothing has worked. How can I resolve this?

@Stefanie Langwerden White-filled frames were used to cover the arrows and they don’t align properly to the large shapes. I refilled them with yellow so you can see them. File attached.

If you’re going to do it that way, draw them all the way out to the full width.

If I understand this correctly the problem is that the background area to the right of the white paths is actually 10%k so your [Paper] line will always show.

The Paper swatch is a “knock out all ink here” color, so it’s leaving a gap., Change the path color to 10” [Black] and it will blend with your gray text background.

It’s not a path, @Peter Spier, the OP is using small white boxes to knock out the lines to form the arrows. I posted a version of it where I changed the color to yellow so you can see it.

Ah. I misinterpreted which white line was the problem.

Thanks

Hi @Stefanie Langwerden , Have you tried proofing the PDF/X-4 page to a high resolution printer? If I check the Y positions of the white mask and black boxes they match.

When viewing in Acrobat, check your PDF/X-4 at a high magnification— 800%+. Acrobat’s anti-aliasing for screen output can affect the PDF preview. Acrobat has a Page Display Rendering preference, which can affect the alignment of objects at relatively low screen resolutions.

Personally, I would have created the bars in Illustrator where you have better options to control the shapes, but another way you could do this in InDesign is to create the bar shape as a frame, then Cut all the objects (Group them first) and then Paste Into the new shape to create a clipping mask.

Not sure what the problem is from your description. Can you post side x side pics with InDesign and Acrobat?

First, can you please indicate on your screenshots what white areas should not be there.

How do these elements look in InDesign and what settings are applied to them?
