  • Patent number: 11422755
    Abstract: Systems and methods for pseudo spot color printing on a printing device include receiving a print job specifying a spot color at a printing device not accommodating ink corresponding to the specified spot color, determining and storing a plurality of process color planes associated with corresponding process color inks accommodated by the printing device, and storing the plurality of process color planes in a memory of the printing device. A single spot color plane is determined and stored for the specified spot color. A plurality of other common planes is determined and stored. Upon reaching an end of the surface of the print job, the single spot color plane is converted to a plurality of spot color planes, which is merged with the plurality of spot color planes prior to printing a corresponding portion of the print job.
