Heat Press Settings & Batch Time Calculator

How it works

cycle = press time (+ second press) + handling + pre-press · pieces per hour = 3,600 ÷ cycle · cost per piece = (hours × wage + hours × press kW × duty × $/kWh) ÷ pieces

Every transfer chemistry has a window: heat-transfer vinyl needs its adhesive melted into the fibres without scorching, sublimation needs the dye to turn to gas and the polyester pores to open, DTF needs the powder adhesive to cure, and plastisol needs firm pressure to force the ink film into the weave — which is why temperature, time and pressure come as a set. Fabric shifts that set: polyester dyes migrate at high heat, so temperatures drop and blocker layers appear, and nylon melts. Once the settings are known, a production run is arithmetic on the cycle time, and handling — not pressing — is usually the larger half, so shops speed up by overlapping dressing with pressing rather than by shaving seconds off the press.

Worked example

Standard HTV on cotton: 150 °C (302 °F) for 12 seconds at medium pressure, warm peel. With 45 seconds of handling the cycle is about 61 seconds, so a single press does 59 shirts an hour; 60 shirts take about 1.0 hour, costing roughly $0.31 each in labour at $18/h plus well under a cent of electricity from a 1,500 W press.
