Sublimation Blanks & Mugs Setup

Fading indicates low temperature or insufficient pressure. Muddy colors suggest overheating. Calibrate your heat press temperature with a laser thermometer, adjust pressure gradually (0.5 psi increments), and test on scrap blanks first.

Polyester-coated blanks have a synthetic polymer layer and require 350-375°F; ceramic blanks have a glazed polymer surface and need 385-400°F. Ceramic holds colors longer-term but is more expensive. Polyester offers faster turnaround.

No. Uncoated ceramic will not accept sublimation dyes—colors won't transfer and will wash off immediately. Always buy blanks explicitly labeled 'sublimation-ready' or 'polymer-coated.'

Ghosting happens when paper shifts during heating. Secure paper firmly with tape, ensure even pressure across the platen, and use a Teflon sheet on top to reduce friction. Test pressure with scrap blanks.

Yes, but wait 24-72 hours depending on blank type. Wash cold water with mild soap, avoid abrasive scrubbing, and don't use bleach. Machine washing may fade colors faster than hand washing.

Keep humidity between 35-55% relative humidity. High humidity (>60%) causes sublimation paper to absorb moisture and curl; low humidity (<30%) makes paper brittle and increases static. Use a humidifier or dehumidifier as needed.
