ARTJET UV flatbed (XP600 / Flexi RIP) / Substrate for tactile braille (White+Varnish stack)

Substrate for tactile braille (White+Varnish stack) on ARTJET UV flatbed (XP600 / Flexi RIP)

guide

Layer order

White+Varnish simultaneous layering then final Color (Black) contrast pass

White layers

Channels 7–12 at 400%; bottom White density 100%

CMYK layers

1 (final black contrast)

Varnish

Channels 13–18 at 400%; bottom Varnish density 100%; enable Light Oil / Varnish Mode

Print mode

Uni-directional; raise head height +0.3–0.4 mm above substrate (e.g. substrate 1.5 mm → head 1.8–1.9 mm)

Durability

Target braille height ~0.5–0.7 mm; 400% = 4 repeat passes (time ×4)

Notes

ARTJET guide: stack White+Varnish together for height; Light Oil Mode required so carriage keeps moving to cure final varnish; bi-directional risks edge scatter when head raised
