Abstract

A method of printing a high density image. An image is accessed, wherein the image has a plurality of pixels, and each pixel has an r,g,b value. For each pixel, each r,g,b value is separated into separate grayscale components and color components. A lookup table is applied to each grayscale and color component to generate an ink value for each of the print heads. The ink values are combined to produce a final ink output value for each pixel, and the final ink output values are employed for printing on medium using an ink-jet printer.

Claims (17)

1. A method for printing on medium using an ink-jet printer having a plurality of print heads, comprising:

accessing an image having a plurality of pixels, each pixel having an r,g,b value;

for each pixel, separating each r,g,b value into separate grayscale components and color components;

applying a lookup table to each grayscale and color component to generate an ink value for each of the print heads;

combining the ink values to produce a final ink output value for each pixel; and

employing the final ink output values for printing on medium using the ink-jet printer,

wherein the ink-jet printer includes 10 print heads (K,Light K,LLK,C,Lc,M,Lm,Y,O,G), the grayscale and color components are R,G,B,C,M,Y,K, and the final ink output value for each pixel for each of the print heads is determined by the formulas:

K =Grayscale K

Light K =Grayscale LK

LLK =Grayscale LLK

C →Grayscale — C+ 255−( G — C+ 255−( M — C+ 255−( B — C +(255− C — C ))))

Lc →Grayscale — Lc+ 255−( G — Lc+ 255−( B — Lc+ 255−( C — Lc+ 255−( M — Lc +(255− Y — Lc )))

M →Grayscale — M+ 255−( R — M+ 255−( B — M +(255− M — M )))

Lm →Grayscale — Lm+ 255−( R — Lm+ 255−( B — Lm +(255− M — Lm )))

Y→Y — Y+ 255−( C — Y+ 255−( G — Y +(255− R — Y )))

O→R — O

G→G — G.
