Patent ID: 8474934

Claim:
An inkjet printing system, comprising: a plurality of reservoirs, each configured to house one of a plurality of different colored inkjet inks of an ink set; an inkjet fluid ejector fluidically coupled to the plurality of reservoirs, the inkjet fluid ejector being configured to deposit one or more of the different colored inkjet inks as ink drops onto a print surface during printing; and a processor selectively and operatively connected to the inkjet fluid ejector, the processor configured with a non-transitory computer readable medium embodying computer readable code for controlling micro-coalescence of the ink drops when the ink drops are deposited onto the print surface during printing, the computer readable code including: i) computer readable code for controlling depositing of the ink drops onto the print surface according to a predefined order of color based upon solids content so that an ink with a lower solids content is printed prior to an ink with a higher solids content; and ii) computer readable code for reducing a number of printing passes to three printing passes, four printing passes, or five printing passes to increase an ink flux per printing pass, the computer readable code for reducing the number of printing passes including: computer readable code for depositing a yellow ink alone during one of the three, four, or five printing passes; computer readable code for depositing a magenta ink alone during an other of the three, four, or five printing passes; and computer readable code for depositing any of a light cyan ink, a cyan ink, a light magenta ink, or a black ink during one additional pass of the three printing passes, during two additional passes of the four printing passes, or during three additional passes of the five printing passes.
