Abstract

A system to produce print data corresponding to a multi-level value of a pixel includes a first determining step to determine a first amount of low-penetration black ink corresponding to the multi-level value, a second determining step to determine a second amount of high-penetration black ink corresponding to the multi-level value and a printing step to print the pixel using the first amount of low-penetration black ink corresponding to the multi-level value and the second amount of high-penetration black ink corresponding to the multi-level value.
