The artists will need to upload a new file to be printed at 10x16, if a 10x16 file is not available the prints will have to be made at 10"x12.5". Also to re-address the 100 dpi issue a Kamori 5-stage is an offset printing press, our prints are made on a wide format digital printer, as the set-up costs on an offset press are prohibitive for runs under 250 pieces. Also the digital printing gives a larger color gamut for more vibrant reproductions. But nonetheless they are completely different processes and the same resolution rules do not apply. Hope this eases any concerns. Cody Design To Print
