Increasing dpi in a submission?
I recently tried to submitted my art, but I got a message back telling me it was declined because the image quality was too poor. The message said to submit a 72dpi copy of my artwork, so I did. Then yesterday I got another email telling me the same thing. I scanned the original submission at 300dpi. The image submission is currently 4.12M with a width and height of 1200 pixels, 16.667x16.667 inches, and a resolution of 72dpi or pixels/inch. After trying and trying again, I seem to not be getting something right. Could someone please tell me what am I doing wrong so that it may be accepted?
