An inkjet printer has process color printheads and spot color printheads each comprising a plurality of inkjet nozzles. The printheads are arranged such that the spot color printhead has fewer nozzles allocated for each spot color then the process color printhead has allocated for each process color. For areas requiring spot color printing the printing rate may be reduced or the dot size and/or the dot spacing may be varied for spot colors to enable printing at the same rate as for process colors.

High throughput inkjet printer with provision for spot color printing

An inkjet printer has an array of individual inkjet printheads to allow high-speed printing in standard process colors while also having additional nozzles that can be used to print spot colors. There are fewer inkjet nozzles allocated to each spot color than each of the process colors so that the printing speed for printed sheets containing spot colors may be less than for printed sheets only containing the process colors.
