Bad preview of placed vector file paths - jagged

[Juan Cano]

This is not the end of the world, but I am getting this terrible preview issue of placed vector logos into my document. I am in High Quality Display Mode. Happens with vector logos I am placing (EPS, SVG).

Working on marketing materials with sponsor logos, so I am using logos from other companies. 

I opened one of the EPS and re-saved it as both EPS and AI but didn't fix it. I don't see it in all the logos but see it in a bunch of them.

Mostly a pain in the butt since I know they will print correctly.

That looks more like a GPU hiccup than a low quality preview. If you're on a Mac, toggle GPU acceleration on or off. 

[Juan Cano]

Tried the toggle and didn't make a difference. Hmmm.

Hi @Juan Cano , Does it happen if you save the EPSs and SVGs as .AI format? EPS and SVG both have limited color mangement and live transparency capabilities, so for print .AI is a better format.

[Juan Cano]

Never had issues with EPS, that's a native format and not doing any transparency, but thanks for the tip. But I did save one as AI as curiosity. Here's the weird part which makes me think is a GPU issue like John Messinger said. In the screenshot attached, I resaved the logo as an .AI. I replaced it ON THE LEFT and suddenly the logo on the RIGHT was smooth. Figured I did it wrong. But I didn't. The one on the RIGHT was still the EPS but now it was smooth. And the one on the LEFT is the .AI and it's choppy. Just a silly issue. Will restart Mac and go from there. Thanks.

Does it happen if you only place .AI format?

EPS and AI

[rob day]

some vendors specifically ask for EPS

I meant don’t place any .eps files at all and see if that solves the problem.

There would be no reason for a printer not to accept placed .AI or .PDF for vector art—the .eps format is over 30 years old and includes a low res TIFF image for its preview, which might be causing the display problem.

Avoid EPS as itis an outdated file type. 
Avoid SVG for print or pdf. Use it for web applications and epubs. 

use PDF/X-4 or AI files in InDesign for vectors. 

[Juan Cano]

Will try; some vendors specifically ask for EPS. Good tip on SVG. This issue is happening with AI files as well.

[Juan Cano]

Thanks for the EPS tip; will avoid going forward.

Did you check the Outline View of the EPS files in Illustrator? Maybe there is a problem in the logo files which only shows in preview.

[Juan Cano]

Yep, files are fine, clean and smooth. It's happening on AI files as well. 

Restarted Mac, ran diagnostics etc. I can live with it, it's just extra annoying.

BTW, didn't realize EPS was outdated. Feel like I remember when it came out, LOL. Will stop using.

Can you share the problem eps? You can attach it to a reply.

[Juan Cano]

I FIGURED IT OUT!!!  Damn InDesign.

I have the logos rotated 90deg reading top to bottom. That creates the preview issue. If I rotate back to horizontal it disappears. The logos on the next page (These are 2-side feather flags) are rotated 90 degrees reading bottom to top and the preview looks fine. 

it's the rotating 90 deg in one direction that causes the issue.

This is definitely a bug. Just placed our company logo, looks fine, rotate 90deg pointing down, preview issue.  

Could you try recreating in your system? use the Ameresco logo attached.

You forgot to attach the file

[Juan Cano]

Somehow it didn't attach. But like I mentioned, it happens with ANY vector logo.  Try with these please but also try with a file of yours. Curious.

[Juan Cano]

It only attaches one at a time?

[rob day]

I’m not seeing a problem, so it might be specific to your graphics card hardware.

Does it happen with a file if you don’t outline the text and save as .AI? Outlining removes the font’s hinting.

.AI is based on PDF so besides supporting live transparency and embedded color profiles, you can also embed the fonts when font embedding is permited by the font vendor:

Does the attached sample work?

[rob day]

My .ai wouldn’t attach, try this:

Found another post. https://community.adobe.com/t5/indesign-discussions/problem-when-rotating-linked-ai-file-in-indesign...

It is a GPU issue. I went in and unchecked the GPU performance and it corrects it. Of course now I see these lines on my solid color fields..... it never ends does it? LOL.

My old Mac performed much better than this new M1. Very unhappy with it.
