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,

In addition to what Ton said, I believe they is a resampling = downsampling of the two images somewhere along the way.

Edit: Ton, are we posting rather late or rather early?

Outside of the fact that the icons to the left and right are not vectors, I'm not sure I'm following the responses to be honest. Opening the icons.pdf file doesn't show the icons in poor quality even though the ones to the left and right are in image format. Yes, I understand if you zoom in, it will be in poor quality, but you have to really zoom in for that to happen. If you change the size of the icons in the icons.pdf file, the quality still stays the same.

I would assume if there's an issue with the icons to the left and right, it would show in poor quality when opening the icons.pdf file as well (not just the other file I uploaded which is what happened when I pasted the icons into that file).

The issue comes in to play when you paste them into another file. Something is happening in the transfer, but I don't know what I'm doing wrong or how to avoid the quality loss. Can someone please help with this part?

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?
