Every time I want to export my InDesign file to pdf (print), the layout of some of the shapes changes and I have no clue how to fix it. The left row of bars is a print screen from In design the right row of bars is a print screen of the pdf file. As you see, some bars in the pdf file have become thicker than others.
This is what I did: I've created 10 small identical rectangles (copies), some have an opacity of 100% others of 50%. The small rectangles were aligned by the function "align spacing". After that I duplicated the 10 rectangles 5 times and pasted them below eachother.
This is what I've tried to fix it: I've grouped all bars together with some of the surrounding text (that doesn't change) . I've pasted a white square on the bottom layer of my page. I created a compound path of all squares with the same opacity I exported the file to an interactive pdf instead of print. And I changed the output to another random setting. Non of these sollutions did the trick
I'm using InDesign 2015 on Windows 10 my file uses CKYM colours
Does the problem disappear if you zoom in?
If I zoom in a lot (400%) it does disappear. It is important though that the file looks good when read on a computer screen as well.
This is only a screen issue, as small objects have to align to the screen's pixel grid. You cannot avoid it on screen as it is the same with thin lines. On print is this not a problem.
If this causes you a problem on screen and if you have to use the document on screen you will have to consider a different design as there is no solution which would be applicable to you and the multitude of PDF reader devices and applications out in the market and you have no chance to get control over it.
