Abstract
A method improves transfer efficiency of ink images on an image receiving member that were formed with small ink drops. The method includes identifying image data that correspond to ink drops that have a mass less than a predetermined threshold and that fail to comingle with another ink drop ejected with reference to the image data, modifying the identified image data to generate ink drops that comingle with at least one other ink drop ejected with reference to the image data, generating firing signals for inkjet ejectors in a print head with reference to the image data and modified image data, and ejecting in response to the firing signals a plurality of ink drops from the inkjet ejectors for each identified image data to enable a coalesced ink drop to form on an image receiving surface that has a mass that is greater than the predetermined threshold.
