UV on Leather (UV)

UV Printing on Leather (UV)

UV prints on leather without the heat damage a heat press causes, which matters for PU and coated leathers.

Substrates: PU leather, finished genuine leather

Settings that work

Temperature	No heat
Press time	3–6 minutes
Pressure	N/A
Peel	N/A
Wash care	Dry wipe

Settings are a starting point, not gospel. Film batches, ink lots and press calibration all shift the ideal number — always pull-test a sample before a paid run.

What goes wrong, and how to fix it

Problem	Fix
Ink cracks at flex points	Finished leather flexes. Keep prints small and away from folds.
Oils repel the ink	Wipe with IPA and use a primer on oiled leather.

Good fit

Wallets
Bag panels
Patch-style logos

Where it fails

Suede, nubuck, oiled leather

What to buy for leather (uv)

Weekly volume	Machine class	Why
Small items (cases, pens, keychains)	A5 / A4 flatbed	One object at a time. Enough for gift orders, too slow for batch retail.
Up to 30 × 45 cm (plaques, tumblers with jig)	A3 flatbed	The default size for gift and promo work. Add a rotary jig for cylinders.
Signs, panels, batch cases	4060 / 6090 flatbed	Bed size decides throughput. A 6090 prints a full panel in one pass.

Volume bands assume one operator and a standard 38 × 38 cm press. Verify with a sample before committing to a machine size.
