Methods for transferring fluid droplet patterns to substrates via transferring surfaces

摘要

In accordance with the present invention, an inkjet pattern with high dot integrity is printed on a wide range of paper types with high reliability at speeds comparable to offset printing. The method consists of a combination of steps by which ink droplets, ejected from an inkjet array head with built in redundancy, are deposited in-line to avoid visual imperfections and are heated on a patterned intermediate transfer surface to decrease their size and increase their viscosity before being transferred to a printing surface. Dots immediately adjacent to one another in the pattern are printed in separate passes to retain dot integrity.
