Substrate for 2.5D / textured image (white relief then color) on ARTJET UV flatbed (XP600 multi-channel white)
guideSurface prep
Photoshop alpha/spot-color levels for gradient white height (not flat spot white)
Layer order
White relief (100–800% repeat passes) → Color on top
White layers
100%=1 pass; 200%=2; 800%=8; bottom White density must be 100%
CMYK layers
1 final color pass
Varnish
optional / not required for this texture method
Print mode
Same channel-repeat approach as braille; multi-channel white speeds height vs single-channel heads
Notes
White builds tactile 2.5D texture; color printed last. Gradient white via Photoshop alpha levels; Illustrator cannot do the gradient white method described.
