摘要
Provided is a printing method for multi-pass printing with column thinning in which the multi-pass number is not restricted to being a multiple of the column thinning number. A mask pattern of a size corresponding to the number of printing elements in use is prepared, and divided into blocks 1 to P. Taking R(x) to be the mask pattern for the region corresponding to block x (where x=1 to P), these P block mask patterns satisfy the following condition. Namely, for all integers s obtainable between the values from 1 to M, the arrangements of printing pixels exist in a complementary relationship with each other in the combination of mask patterns R(s), R(s+M), R(s+2M), and so on to R(s+N×M). However, for all s, N is taken to be the largest integer satisfying s+N×M≦P.
