PRINT METHOD, PRINT APPARATUS AND PRINTED UPON MEDIUM

摘要

A print method, print apparatus and printed medium include forming a black portion of an image from two inks. The first ink (62) includes first carbon black pigment units (66) and a first binder (68). The first carbon black pigment units (66) have a median dibutylphthalate absorption (DBP) of at least 95cc/100g. The first ink (62) has a first ratio of the first carbon black pigment units to the first binder. The second ink (64) includes second carbon black pigment units and a second binder. The second ink has a second ratio of the second carbon black pigment units to the second binder less than the first ratio. The first ink and the second ink together have a median total weight per unit area of at least 70 percent of an absorptive capacity of the print medium and overlap one another, wherein the second ink is at least 54 percent of the total weight per unit area.
