Patent ID: 8305409

Claim:
A method for forming a plurality of non-contiguous features on a receiver element, the method comprising: operating a first multi-channel imaging head to direct imaging beams along a scan path to transfer a first non-contiguous feature and a second non-contiguous feature from a donor element to the receiver element by a thermal transfer process wherein the first and second non-contiguous features are spatially separated from one another at least in a sub-scan direction; operating a second multi-channel imaging head to direct imaging beams to transfer a third non-contiguous feature from the donor element to the receiver element by the thermal transfer process, wherein the third non-contiguous feature is between the first and second non-contiguous features and is spatially separated from each of the first and second non-contiguous features at least in the sub-scan direction; and wherein each of the non-contiguous features is screened with at least one of a halftone screen and stochastic screen.
