Issue when rasterizing artwork in illustrator

[carlp31101002]

We have an issue that has been introduced in recent (past 12+ months) updates to illustrator.

When we rasterize artwork, illustrator is rasterizing in a white pin line a random spot in the artwork.

We can usually work around this by undoing and re-rasterizing with a small adjustment made to the resolution. It takes between 1 and 5 attempts to get a successfull result.

This is a timely work around and if missed the pinline is visable in our large format prints.

Does anyone hace a resolution to this issue?

When you Rasterize, what is your Anti-aliasing setting? If it's Type Optimized, switch it to Art Optimized

Thanks Brad. Yes our anti-aliasing setting is art optimized.

We have been rasterizing potential proplem files for print for 10+ without an issue.

This has been introduced in a recent update.

Hello @carlp31101002,

I'm sorry to hear about your experience. Would you mind sharing more details, like the OS/Illustrator version, a sample AI file, and the exported file after uploading them to a file-sharing service, so I can try to replicate this on my end?

Looking forward to hearing from you.

Do resolutions with a multiple of 72 (144, 288) ppi work better?

Rasterizing vector artwork and yielding good results can be a tricky process. Much of it depends on how the artwork is designed, sized and positioned in relation to the target pixel grid and its resolution level. This matters a great deal when designing graphics for things like LED-based variable message signs.

If you are doing large format printing work is there a reason why you're having to convert the vector art to pixel form before printing? What kind of large format RIP does your shop use?
