High throughput inkjet printer with provision for spot color printing

摘要

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.
