USING INKJET PRINTER TO APPLY PROTECTIVE INK

摘要

A method of determining and applying a protective ink amount (p(x,y)) to be printed in addition to a plurality of colored ink amounts (h(x,y,c)) to make colored pixels in an image including determining multitoned colored ink amounts (h(x,y,c)) using a multitoned (50) processor responsive to colored ink amounts (i(x,y,c)), determining a first protective ink amount (pl(x,y)) responsive to the multitoned colored ink amounts (h(x,y,c)) and determining a second protective ink amount (p2(x,y)) responsive to the colored ink amounts (i(x,y,c)). The method also includes determining the protective ink amount (p(x,y)) responsive to the first protective ink amount (pl(x,y)) and the second protective ink amount (p2(x,y)) to provide adequate durability for the image, and applying using an inkjet printer the colored ink amounts and the protective ink amount to make the colored image pixels.
