We'll take just about any editable electronic format, as we can convert most files into the formats our printers use. For the fastest possible service, send your art in vector/print-ready format, art in in other formats will require additional time for optimization. For exact color matching, PMS is preferred. Art must be submitted upon order confirmation, by simply attaching it to a response to the confirmation email. Non-electronic art may incur additional costs to coax onto a computer.
