Abstract

A method of generating control data for a printing system includes receiving image data comprising an image to be printed by the printing system, determining a presence of a control mark in the image data, and generating control data for the printing system based on the control mark, the control data including at least an indication of the presence of the control mark.

First claim

What is claimed is:

1. A computer-implemented method of generating control data for a printing system, the method comprising:
receiving image data comprising an image to be printed by the printing system;
receiving instruction data for a print job associated with the image data to be printed by the printing system;
determining a presence of a control mark in the image data in response to receiving a flag associated with the instruction data, wherein the flag indicates a digital front end is to determine the presence of the control mark; and
generating control data for the printing system based on the control mark, the control data including at least an indication of the presence of the control mark.

2. The method of claim 1 , comprising:
determining a location of the control mark in the image data;
wherein the control data further includes an indication of the location of the control mark.

3. The method of claim 1 , wherein the control mark is a component of the image to be printed.

4. The method of claim 1 , wherein the control mark is located in a region outside of the image to be printed within the image data.

5. The method of claim 1 , comprising:
receiving the instruction data for the print job associated with the image data at the digital front end of the printing system; and
determining whether the instruction data comprises the flag, the flag indicating that the digital front end is to automatically determine the presence of the control mark in the image data;
wherein determining the presence of the control mark in the image data is performed by the digital front end responsive to the instruction data comprising the flag.

6. The method of claim 1 , comprising:
generating print data comprising two or more sets of the image to be printed, the image data comprising a plurality of control marks;
wherein generating control data for the printing system comprises generating control data including an indication of the presence of a subset of the plurality of control marks.

7. A printing system comprising:
a digital front end comprising a processor and memory; and
a printing apparatus communicatively coupled to the digital front end;
wherein the digital front end is to:
receive image data comprising an image to be printed by the printing apparatus;
receive instruction data for a print job associated with the image to be printed by the printing apparatus;
determine a presence of a control mark in the image data in response to receiving a flag associated with the instruction data, wherein the flag indicates the digital front end is to determine the presence of the control mark;
generate control data based on the control mark, the control data including an indication of the presence of the control mark; and
transmit the control data to the printing apparatus.

8. The printing system of claim 7 , wherein the digital front end is configured to convert the image data to raster data for printing.

9. The printing system of claim 7 , wherein the printing apparatus comprises a printer to print the image, wherein the control data is used to calibrate the printing of the image.

10. The printing system of claim 9 , wherein the printing apparatus comprises at least one of:
a pre-print component arranged before the printer that is configured based on the control data; and
a post-print component arranged after the printer that is configured based on the control data.

11. The printing system of claim 7 , wherein the printing apparatus comprises electronic circuitry that implements an application programming interface to receive the control data.

12. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor, to:
obtain image data corresponding to an image to be printed by a printing system;
obtain instruction data for a print job associated with the image to be printed by the printing system;
parse the image data to locate a control mark in the image data in response to receiving a flag associated with the instruction data, wherein the flag indicates a digital front end is to determine the presence of the control mark;
generate control data based on the control mark, the control data including an indication of the presence of the control mark; and
transmit the control data to the printing system.

13. The non-transitory computer-readable storage medium of claim 12 , wherein the instructions, when executed by the processor, further cause the processor, to:
determine a location of the control mark in the image data; and
generate the control data to include an indication of the location of the control mark.

14. The non-transitory computer-readable storage medium of claim 12 , wherein the instructions, when executed by the processor, further cause the processor, to:
parse a portion of the image data to locate a control mark in the image data.

15. The non-transitory computer-readable storage medium of claim 12 wherein the instructions, when executed by the processor, further cause the processor, to:
determine whether the instruction data comprises the flag, the flag indicating that the processor is to automatically parse the image data to locate the control mark in the image data;
wherein parsing the image data to locate the control mark in the image data is performed by the processor responsive to the instruction data comprising the flag.
