what is the correct safest file size set up for designed images/logos in photoshop
Hi community.
I'd like to understand regarding file size set up, if I am to design a logo or enhance a logo/image in PS. For example if I am to design a logo in Illustrator or 3D software, as vector or PNG, and import it into PS, I know for printing it has to be 300DPI Cmyk, but how about the file dimensions which would be enough for large scale printing, that would look crisp and not pixellated.
Thank you
