What Is Sublimation?
Sublimation is a way to print full-color designs onto products like mugs, tumblers, shirts, and keychains. You print your design on special paper using special ink, then use heat and pressure to transfer it permanently onto the product. The ink turns into a gas and bonds with the surface — it won't peel, crack, or fade like vinyl or iron-ons.
Why Cotton Doesn't Work
Sublimation ink only bonds with polyester or special coatings. If you try to press onto a 100% cotton shirt, the design will wash out almost immediately. Always use polyester shirts (or at least 65%+ poly blends) and poly-coated blanks.
Why 300 DPI Matters
DPI stands for "dots per inch." It controls how sharp your print looks. Always set your design to 300 DPI. If you use a lower number (like 72 or 150), your print will look blurry or pixelated. 300 DPI means your design has enough detail to look crisp and professional.
Why Mirroring Matters
Before you print, you need to flip your design horizontally ("mirror" it). Your design will look backwards on the paper — that's correct! When you press it face-down onto the blank, it transfers the right way around. If you forget to mirror, all your text will be backwards.
Why Test Prints Matter
Before using your expensive sublimation paper, print your design on regular paper first. Hold it up to your blank to check the size and position. This simple step saves money and prevents costly mistakes.
Why Moisture Ruins Prints
Moisture trapped in fabric or the paper will cause blotchy, spotty prints. That's why you pre-press shirts for a few seconds before applying your design. It drives out the moisture. Store your sublimation paper in a dry place — not in a damp garage.
Why Pressure Matters
The heat press needs enough pressure to keep the paper flat against the blank. Too little pressure and you'll get faded or uneven prints. Too much pressure on items like caps can cause creases. Medium to medium-high works for most items.
Important Reminder
Sublimation only works on polyester or poly-coated items. It will NOT permanently bond to cotton, wood, glass, or untreated metal. Always check that your blank is sublimation-compatible before ordering in bulk.
