UV on Acrylic

UV Printing on Acrylic

Acrylic is UV printing's best surface: smooth, rigid and takes white ink with high opacity.

Substrates: Cast acrylic 2–10 mm, clear or colored

Settings that work

Temperature	No heat
Press time	3–8 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
Print scratches off	No adhesion promoter on bare acrylic. Wipe with IPA and add a primer coat, or print mirror-reversed on the back.
Visible banding on gradients	Print in unidirectional mode and slow the head speed.

Good fit

Signs and plaques
Awards
Keychains and ornaments
Menu boards

Where it fails

Extruded acrylic (lower adhesion than cast)

What to buy for acrylic

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.
