Abstract

A can imprinting device includes a blanket wheel having a plurality of blankets. Each blanket has a printing surface and at least two of the printing surfaces having a first part and a second part that each have raised and recessed portions. The first raised portion is configured to form a positive image on a can body of the plurality of can bodies. The first raised portion of at least one of the blankets is different in form from the first raised portion of at least one other of the blankets. The second recessed portion is configured to form a negative image on the can body. The negative image is inverse to the positive image. The first part and the second part are disposed relative to each other such that the negative image aligns with the positive image on the can body.
