YBW3800 Type Three-color Printing & UV glazing machine for edge band
(Designed for offline)
1. Design condition:
① This line is used to printing patterns and coating UV lacquer on the surface of wider PVC/ABS edge band.
② It can coat different UV varnish to get different effect like Matt, shine and high gloss, but high gloss effect is not good to slit, so better use it by whole sheets.
③ The effective printing width is 100~760mm, thickness of rolling material is: 0.3-1.2mm.
④ It adopts solvent printing ink and UV lacquer
⑤ Total 3-colors, one is background color, 2 is wood grain designs colors.
⑥ Speed V=2-15m/min.

Part Three: Background Printing Station
► it is used to printing base/background color on the bottom of PVC edge bands. Normally the extruded EB could not match the design wooden color very much, so it needs to printing base color on the EB, which can make top wooden grain design more vivid like true wood grains.
► we adopt double-roller station to printing base color, it can complete cover white color of EB into other colors like brown, black, red and etc. Just for EB, it’s better to make extruded EB with some colors which is near its printed designs, that will look more vivid. At that time, you can adopt one-roller station to printing base color, it’s more flexible.
