When I create seamless patterns (12 x 12 inch, 300 dpi), I end up with seams. Also for some reason, the final patterns are 3600 x 3600 pixels but 72 dpi even though I specified 300 dpi. I am not sure what I am doing wrong. Any insights would be appreciated.
I started with a 1024 x 1024 midjourney image. The goal is a 12 x 12 inch seamless pattern (300 dpi). I upscaled it x 2 and created the pattern in Photoshop which results in a seamless pattern but as soon as I modify the size to 12 x 12 inches, the seams appear. I'm stumped as to how I to achieve the desired result. Any guidance would be greatly appreciated!!
If the first screenshot is your pattern then yes, you will end up with seams because first and last cows are at the edge of repeating pattern. Omit cow in the first column if you want seamless pattern or space cows differently.
Regarding PPI. If you need pattern for Web do not change anything, on the internet PPI does not play any role, it will be ignored. Otherwise do not save using Export As or Save for Web but rather using Save a Copy.
