Whatever your customers are buying — a branded polo, five hundred pens, a photo book — the artwork problem is the same. Somebody has to turn an upload into a file a machine can print. FastEditor does that automatically, across every product category, from one integration.
Product categories differ in who buys them, what they cost and how they are decorated. They differ hardly at all in what has to happen to the artwork. Pick the cluster that matches what you sell.
Colour limits, minimum line thickness and output format differ per technique, not per product. These pages cut across all three clusters.
