Object color management using raster image processors and object detection and semantic segmentation

A printing system, comprising:

• at least one computer processor configured to execute instructions to cause the printing system to:
• receive, by a raster image processor, text and an image for printing on a substrate,
• wherein the image comprises at least one object;
• perform, by an object detection and semantic segmentation module, semantic segmentation on the image to extract the at least one object from the image;
• produce, by the object detection and semantic segmentation module, at least one spot color for the at least one object;
• generate, by the raster image processor, (1) at least one process ink layer based on the text and a portion of the image lacking the at least one object, and (2) at least one specialty ink layer based on the at least one spot color;
• generate, by the raster image processor, print data based on the at least one process ink layer and the at least one specialty ink layer;
• and
• a printing mechanism communicatively coupled to the at least one computer processor and configured to:
• print the text and the image on the substrate using the print data.

A non-transitory computer readable medium storing computer instructions that when executed by one or more computer processors, cause the one or more computer processors to:

• receive, by a pre-flight module, an image for printing on a substrate,
• wherein the image comprises at least one object;
• provide, by the pre-flight module, at least one spot color corresponding to the at least one object by performing semantic segmentation, using an object detection and semantic segmentation module, on the image to extract the at least one object from the image;
• generate, by a raster image processor, at least one process ink layer based on the image;
• generate, by the raster image processor, first print data based on the at least one process ink layer and second print data based on the at least one spot color;
• and
• send, to a printing mechanism, the first print data and the second print data for printing the image on the substrate.
