UV on Signs & Plaques

UV Printing on Signs & Plaques

Small format UV flatbeds handle lobby signs and door plaques that sign shops used to outsource.

Substrates: Acrylic, aluminum composite, PVC

Settings that work

Temperature	No heat
Press time	5–12 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
Banding on large solid areas	Print unidirectional and slow the pass.
Edge chipping on cut acrylic	Cut and polish edges before printing, not after.

Good fit

Lobby and door signs
Awards
Wayfinding plaques

Where it fails

Outdoor signs needing 5+ year UV stability (use a dedicated outdoor ink)

What to buy for signs & plaques

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.
