Screen Printing API
Screen-printing maths as an API, computed locally and deterministically — the ink-usage and cost numbers an apparel printer or print shop quotes a job by. It all turns on “ink mileage”, the printed area a unit of ink covers — in² per pound, with plastisol commonly 12,000–18,000 depending on mesh and deposit. The ink endpoint sizes a run: ink = (print area × prints) ÷ mileage, so a 100 in² design printed 150 times at 15,000 in²/lb takes exactly one pound (454 g, about 3 g a print); pass the design as area or as width × height. The prints endpoint runs it in reverse — how many shirts a tub of ink will do: prints = (ink weight × mileage) ÷ print area, so a pound of plastisol covers 15,000 in², roughly 150 prints of that design before waste, and it takes pounds, kilograms or grams. The cost endpoint puts a price on it: ink pounds × price per pound gives the run’s ink cost and the per-print figure, usually just a few cents — ink only, before screens, garments and labour. Everything is computed locally and deterministically, so it is instant and private. Ideal for screen-printing, apparel-decoration, print-shop and merch app developers, quoting and job-costing tools, and production-planning software. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. Ink only; add screens, garments and labour for a full quote.
