Choose the print face
Start with a smooth cotton jersey for fine type and small line work. Test piqué and textured fleece before selling a detail-heavy design. Print the smallest size first to make sure your platen and artwork clear the seams.
Check light and dark garments separately
Dark garments may need a white underbase to keep the top colours visible. Compare hand feel and opacity with a single-colour print where that suits the design. Check colour migration on polyester blends and keep samples of different garment colours.
Measure cure and check the result
Use the ink supplier’s instructions for your ink system and test the print itself. A dryer set point does not establish that the ink film reached its required cure conditions. Wash the approved sample and check edges, opacity and adhesion.
