Need help with Illustrator workflow

[mike5E6D]

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.

Mike,

Exactly how do you save those smaller icons as PDF > Which preset are you using (Smallest File Size, custom preset (with which resolution/downsampling), or which other)?

Thanks for your continued support @Jacob Bugge. I've a screenshot to show you all the settings before saving.

Mike,

There seems to be only a limited downsampling, nothing to explain the issue. You can see a real downsampling issue here,

Still pondering.

I hope someone else will, too.

Someone?

rather late, Jacob 🙂

Looks like you have View > Pixel Preview turned on.

[mike5E6D]

I checked and I did not find it to be turned on.

Try to get the vector version.

[mike5E6D]

I can't get the vector version.

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

[Jacob Bugge]

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.

[Ton Frederiks]

Good to hear that helped.

[Jacob Bugge]

Thank you for sharing, Mike.

It is good to see that it was a downsampling issue after all, and to see a justification of my disliking downsampling, which Ton has now proved to be an unruly beast lurking in the shadows, only waiting for an unusual workflow to strike.
