The complementation emergence data matrix is obtained by following formula:
P '=E-P
Wherein, E is the unit matrix, and the element in the unit matrix is all 1, P ' for the complementary emergence data square Battle array, P are the emergence data matrix.
The first emergence print data matrix is obtained by following formula:
M1=M × P
Wherein, M be the first print data submatrix, × be matrix point multiplication operation, M1 be it is described first sprout wings printing Data matrix；
The second emergence print data matrix is obtained by following formula:
M2=M ' × P '
Wherein, M2 is the second emergence print data matrix, and M ' is the third print data submatrix.
