quick question. I've got a bunch of illustrations from the 1400's-1500's, and I would like to know how to figure out how large I can print this on art paper.
The purpose is for art prints, they're all multiple sizes and most came to me in the size of a book page. I am aware they should be around 300ppi and I should divide W&H by PPI to get the optimal size, however, I've seen much larger versions of these images on prints (an image that was 3000x2500 pixels on a print of about 40x60 cm) which looked good.
Right now I've been just resizing the images with PS, keeping the PPI at 300 and increasing the size in cm (at cost of file size), however, I have no way to corroborate how good or bad these prints will look and how large should I actually be printing them at.
Thank you all for your help!
