Question

Need help with Illustrator workflow

Hello,

I'm working on designing supplement labels and for some reason the logo is showing extra lines around it. I've included a couple of the supplement labels with yellow arrows pointing to the extra lines so this can be seen. You don't see the lines with the .ai version of the file, but they show in PDF and when the labels actually print on the supplement. I'm pasting the logo into the label as an image.

Since you can't see these lines in the .ai version of the file, how do you even remove them? Is there a way to remove these lines or am I missing something?

Thank you for the assistance.

Even with the default compression the result can be as horrible as you have encountered.

When scaled to a very smal size, resampled and jpeg compressed during PDF creation, I can replicate the result.

Try to save the PDF with Compression set to Do not downsample

Now that was a real answer, Ton.

@Jacob Bugge,

Indeed it was a real answer by @Ton Frederiks. It worked gentlemen. The trick lied in setting the color bitmap images in the compression section before saving to do not downsample. Thank you both for your patience and assistance with this. All good for now.

They are probably caused by resampling the logo when exporting the PDF.

This is just a circle - why is it even a raster image?

Thanks for replying @Monika Gause. It wasn't my intention to create a raster image, but rather redact details for privacy.

What do you mean by resampling the logo? Do you have any thoughts on how I can fix this and/or go about it differently? I need to include the logo as part of the label.

Mike,

I still believe there is a downsampling as I said.

This statement in your earlier post,

"The issue is when you take the icons from the icons.pdf file, put it in another file in .ai format, make the icons smaller and save as PDF. When you open that file then in PDF, you'll see the poor quality of the icons."

may hold the clue.

Exactly how do you save those smaller icons as PDF?

I believe you may limit the resolution/quality in that step, thereby downscaling the icons to a lower resolution and thereby a smaller size in pixels x pixels.

I copy the icons from the icons.pdf file (where the icons show fine regardless of the size) in .ai format, paste them in the file I'm working on in .ai format, make the icons smaller and save the file in pdf format (I click on file, save as and save it as a PDF).

In the icons.pdf file, you can make the icons smaller, save the file as a PDF and the quality will be just fine. For some reason, when you make them smaller in the other file though and save as a PDF, the quality goes bad.

How can I avoid this?

I dont see a logo, all I see is transparency indicated by checkerboard pattern, I there something wrong with your screenshots, or am I not understanding your issue?

Thanks for reply @Mike_Gondek10189183. The circle is part of the logo. Nothing is wrong with the screenshots. I have redacted the details for privacy.

If you notice the placement of the yellow arrows, you'll see the issue in terms of the lines on the circles. It's more clear in the other screenshot. Any thoughts on the issue?
