How It Works

HP Indigo's 4-hit white ink system allows variable opacity printing. Each HP White layer (1-4) can carry any opacity value from 0-100% per pixel. Coverage is additive: 4 layers at 100% = 400% total coverage.

Sequential Fill: HP White 1 fills first, then 2, 3, 4
Even Distribution: Coverage split equally across all 4
True opaque white on dark substrates needs 300-400%
