System and method for detecting color conversion problems in a printed image

A system comprising:

• a printing device;
• a print server;
• a processor;
• and
• a memory storing instructions that, when executed by the processor, configure the system to:
• initiate a smoothness determination including:
• identify a region of interest on an image for a print job, wherein the region of interest comprises pixels;
• receive a pixel color value, for at least one color plane, for each pixel in the region of interest, and pixel color values for pixels immediately adjacent to the region of interest;
• calculate an average pixel color value, for a group of neighboring pixels immediately surrounding each single pixel in the region of interest;
• operate a comparator to compare the calculated average pixel color value of the group of neighboring pixels to the pixel color value of the single pixel corresponding to the group of neighboring pixels;
• calculate a number of instances where the pixel color value of the single pixel differs, by more than a first threshold value, from the average pixel color value of the group of neighboring pixels;
• determine if the number of instances is more than a second threshold value:
• on condition that the number of instances is less than the second threshold value:
• obtain a new image;
• on condition that the number of instances is more than the second threshold value:
• flag the print job for review.

A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a computer, cause the computer to:

• initiate a smoothness determination including:
• identify a region of interest on an image for a print job, wherein the region of interest comprises pixels;
• receive a pixel color value, for at least one color plane, for each pixel in the region of interest, and pixel color values for pixels immediately adjacent to the region of interest;
• calculate an average pixel color value, for a group of neighboring pixels immediately surrounding each single pixel in the region of interest;
• operate a comparator to compare the calculated average pixel color value of the group of neighboring pixels to the pixel color value of the single pixel corresponding to the group of neighboring pixels;
• calculate a number of instances where the pixel color value of the single pixel differs, by more than a first threshold value, from the average pixel color value of the group of neighboring pixels;
• determine if the number of instances is more than a second threshold value:
• on condition that the number of instances is less than the second threshold value:
• obtain a new image;
• on condition that the number of instances is more than the second threshold value:
• flag the print job for review.
