Hatched Gradient Illustrator + Lines in Printing
contrariness Posted messages 17903 Registration date Status Member Last intervention -

Hello,
When printing my document, there are very thin white lines that correspond to the outlines of the images. They don't appear on screen, but they are visible when printed... Do you have any idea where this might be coming from, please?
Also, when I apply a gradient, it appears striped (see attached photo). Do you have any idea about that as well, please?
Thank you.

Either
your printer/computer is malfunctioning
or you’re out of ink
once I printed something and I barely had any ink left, result: there were purple streaks on my image.
I hope this answer will be helpful to you
Did you create a gradient or a transparency?
For the outlines of the images, this may come from a problem with flattening transparencies at the time of printing... unless you did a cutout with the pen tool and it's not perfect...
It's not a good idea to provide the AI file... although it's based on a PDF, it may not be well understood by other software.. versions change frequently!
For the striped gradient, I simply opened Illustrator, created a rectangle, and applied the black/white gradient background like in the attached photo. Before, I didn't have this... it was really very ugly.
For my other problem with the image borders, I had added some transparency... they are PNG files. Do you think that by cropping around them the problem will be resolved? Because they have square and rectangular borders.
For me, this doesn't seem to be a file design problem..
Is it printed in composite or color separation (Offset)?
This banding effect in the gradients occurs when the printer's RIP has been misconfigured... Normally in PS level 3, you can go up to 16,384 levels of gray in 1 inch (but this is still in relation to the resolution; a gradient is like an image).. Visually, you can't see the transitions.
It's at a professional printer...
