A Collage I am working on will be 48" X 72". I was planning to make 24 X 24 collages and stitch them together. Based on software limitations, my maximum size is 5120 X 5120 Pixels. That would give me about 213ppi for a 24 X 24 print.
I am going to get this printed on glossy sheet paper. Does it make sense to use 213ppi, or should I use some round number like 200 instead?
300 is possible but a bit more work. I have to make more small collages and stitch them.
