Ways to Improve Image Quality?
I have been using some AI tools to create some designs for me, but when I upload them to Printful it says that print quality is "ok" and "91 DPI" and it recommends a larger file size.
Now i dont need these designs to be flawless, so maybe "ok" will look more than good enough for my purposes, or maybe it wont ¯\_(ツ)_/¯. I guess the issue is that you dont really know until you print.
But anyhow, are there any good free services that I can use to both increase file size and quality of the images that the AI tools are generating?
Thanks so much for any help!
