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.

Abstract: Example systems and related methods may relate to error detection in multi-threaded systems. Namely, a computing device includes a processor and a memory. The computing device also includes program instructions, stored in the memory, that upon execution by the processor cause the computing device to perform operations. The operations include receiving, by the processor, a communication signal. The communication signal initiates a first thread of at least two threads. The operations include sending, by the first thread via the processor, an inter-thread communication message to a second thread of the at least two threads. The operations include storing, in a trace log in the memory, information related to a state of the first thread and the inter-thread communication message. The operations include identifying an error location based on the information stored in the trace log.
