UV-Printed Medals: Why the Colors Pop and How to Keep Them 🌈

UV ink cures hard within seconds, sits flat on metal, and renders gradients that traditional enamel cannot touch. Three rules keep those colors looking new for years.

Specify Two-Pass Printing

Single-pass UV looks fine until you photograph it under flash — the ink is translucent and the metal base shows through. Two-pass printing (white underlayer + color top layer) gives full opacity and lab-perfect color match. The upcharge is small (about ฿4–6/medal) and the difference in photos is night and day.

Clear-Coat the Print Layer

UV ink is hard but it is still a polymer — fingernails, keys, and other medals scuffing in transit will leave marks within months. A clear UV varnish over the print layer locks the color in and adds a subtle sheen that reads premium. Standard practice for premium running medals; ask for it by default.
