Light border around exported JPEG/PNG

[davidh81484236]

Hello,

I have read through countless threads here about unwanted white or faded borders on exports from Illustrator to JPEGs or PNGs, but none of the suggestions have helped. I have tried the following options:

• Turned off anti-aliasing in the General options
• Selecting None or Art Sampling in the export options
• Export for Screens
• All artboards and objects are on whole numbers, no decimals
• The tiles are even numbers, (10x10 and not 4x8, incase that was a factor)

I am at a complete loss. This never used to be a problem before (I make seamless/repeating patterns), but recently it has completely ruined my work. I'm even desperately trying to import the objects into Photoshop to no avail. I don't know what else to do to get rid of this faint border. I've attached 2 photos of some tiles zoomed into the borders (the white has a red bg in photoshop just to clearly show what is happening). Please help, thank you!

Apologies, I forgot to add: I have seen suggestions to keep it to 72dpi, but the website I use to create these patterns needs them to be 150 or 300dpi as they are printed. Again, this was not an issue in the past so I'm not sure if something has changed on Adobe's end or what. Is there any way for me to maitain those dpi numbers without having to export at a 72 multiple and then resizing it?

Can you share a .ai file that gives the problem?

CC files sharing, Dropbox, Google, WeTransfer...

Here's a link to it on gdrive

Thanks, but that one does not give any border on export. No fractional pixels will be generated when exporting to to 288 ppi or 300 ppi (you are lucky).

Your artboard has 504 pixels wide and height

504/72=7

7x288=2016 px

7x300=2100 px

Hi Ton,

Thank you so much. I am honestly stunned because I copy/pasted this file I sent you from a file that had multiple patterns and it was exporting with the border before at 300ppi. I'm not sure what the difference was, but I'm glad it's somehow working now hahah.

So for any future patterns (because I've recently had quite a few doing the border), the key is to stick to the multiples of 72?

Good to hear that helped. Always check the Upper Left corner in the transform panel or Artboard panel for fractions.

And yes, multiples of 72 are safe, but sometimes (as you can see in my calculations) if you are lucky, 300 ppi will be good too. It is easy to calculate, divide the width or height by 72 and multiply the result by the requested resolution to check for fractional results.
