Measure sellable square inches
Use the final printed width × height for each transfer, then separate customer quantity from the extra copies you plan to print for spoilage.
Calculate material cost
Combine film, ink, powder, maintenance consumables, and any pretreatment or finishing cost. Convert the total to a reliable cost per printable square inch from real purchasing and usage data.
Allocate labor and overhead
Add artwork review, RIP setup, printing, powder/cure, trimming, packing, machine time, rent, utilities, software, and maintenance. Allocate order-level work across the sellable quantity.
Model spoilage
If your measured spoilage is 5%, divide the required customer quantity by 0.95 and round up. Charge based on the total cost of the production quantity, not only the good units delivered.
Convert cost to price
For a 60% target gross margin, divide unit cost by 0.40. Markup and margin are not interchangeable: doubling cost is a 100% markup but only a 50% gross margin.
Set minimums and quantity tiers
Protect small orders with a minimum order or setup charge. Reduce unit price only as setup allocation and production efficiency actually improve.
Test against the market
Compare final prices with local service levels and online transfer vendors, then decide whether your advantage is turnaround, color control, pickup, file help, or specialty service.
