Bug-Lines in Brush

[Nadezda_Kulikova]

Hello, Community!

When I creating a Pattern brush, such lines appear as in the screenshot. With what it can be connected? I restarted the program, it doesn't help. I am attaching the brush settings, everything is standard as I have done a thousand times already and this has not happened.

Need your help

They should not print, is just in the redraw. Have not seen that in awhile are you running an older version of Illustrator? You might see that n a pdf preview in acrobat if the smooth and enhance defaults are turned off.

Thank you for he screenshots, really appreciated. If thee hairlines prints, we will need to look at your pattern vector art brush construction. Did you use unfilled unstroked bounding boxes?

Thanks a lot, i'll try to print when i have an opportunity. But what do you mean "unfilled unstroked bounding boxes" – where this settings is?

You need to create those rectangles and then put them in the back of the brush artwork. If you don't create them, Illustrator do that automatically. If you create them yourself, you can design them exactly the way you need them.
