How to: File > Save As > .pdf
Color space: CMYK (RGB will be accepted, but we cannot ensure a precise color match).

DPI: At least 300dpi (less will be accepted, but we cannot ensure the highest print quality). Some large grand format products accept a lower DPI.
Dimensions: We recommend you upload files that match the same dimensions as the product you are printing.
Inside Margins: Keep all text at least 0.5" from the edge. Anything closer risks getting cut off.
