Printing with target color data
In one embodiment, a processor-readable medium stores code representing instructions that when executed by a processor cause the processor to print a print job, and determine target color data for each sheet of the print job while printing the job. The instructions further cause the processor to continually save the target color data to a server for each sheet of the print job as each sheet is printed.
1. A non-transitory processor-readable medium storing code representing instructions that when executed by a processor cause the processor to:
determine, by a first printer printing a print job comprising a plurality of sheets, target color data for each sheet of the print job while printing; and
continually save, by the first printer, the target color data for each sheet, as each sheet is printed,
wherein the continually saved target color data is received by a second printer to print a portion of the print job simultaneously with the printing by the first printer.
2. The non-transitory processor-readable medium as in claim 1 , wherein the instructions further cause the processor to:
save a job identifier to identify the print job, an identifier to identify the first printer that is printing the print job, and a sheet identifier that associates the target color data with each sheet.
3. The non-transitory processor-readable medium as in claim 2 , wherein the instructions further cause the processor to:
after all of the target color data for the print job is saved, receive a request for the target color data, wherein the request includes the job identifier;
retrieve the target color data associated with each sheet responsive to the request; and
control the first printer or the second printer to print the print job a second time using the retrieved target color data.
4. The non-transitory processor-readable medium as in claim 1 , wherein to determine target color data, the processor is to:
determine pre-calibrated color values;
print color outputs on media sheets using the pre-calibrated color values; and
determine the target color data based on the color outputs.
5. The non-transitory processor-readable medium as in claim 4 , wherein to determine target color data, the processor is to:
measure the color outputs with an image sensor; and
determine the target color data for each sheet based on the measured color outputs.
6. A method of printing with consistent color reproduction comprising:
determining target color data for each sheet of a plurality of sheets in a print job while the print job is printed by a first printer; and
continually saving, in a storage device of the first printer, the target color data for each sheet as each sheet of the print job is printed.
7. The method of claim 6 , wherein the continually saved target color data is received by a second printer to print a portion of the print job simultaneously with the printing by the first printer.
8. The method of claim 6 , wherein determining target color data comprises:
printing color outputs on media sheets using pre-calibrated color values;
measuring the color outputs with an image sensor for each media sheet; and
determining the target color data for each sheet while printing based on the measured color outputs.
9. The method of claim 6 , comprising:
saving identification information for the target color data;
receiving a request for the target color data, the request including the identification data; and
providing the target color data responsive the request for printing the print job a second time.
10. The method of claim 9 , wherein the identification information comprises at least one of a job identifier to identify the print job, a press identifier to identify a printing press that is printing the print job, and a sheet identifier for each sheet to associate target color data with each sheet.
11. A printer comprising:
an image transfer arrangement to print sheets of a print job comprising a plurality of sheets;
a storage device; and
a processor to:
determine target color data for each sheet of the print job while printing; and
continually save the target color data for each sheet in the storage device, as each sheet is printed,
wherein the continually saved target color data is received by a second printer to print a portion of the print job simultaneously.
12. The printer of claim 11 , wherein to determine target color data, the processor is to:
control the image transfer arrangement to print color outputs on media sheets using pre-calibrated color values;
measure the color outputs with an image sensor for each media sheet; and
determine the target color data for each sheet while printing based on the measured color outputs.
13. The printer of claim 11 , wherein to determine target color data, the processor is to:
save identification information for the target color data in the storage device; and
provide the target color data responsive to a request including the identification information.
14. The printer of claim 13 , wherein the identification information comprises at least one of a job identifier to identify the print job, a press identifier to identify a printing press that is printing the print job, and a sheet identifier for each sheet to associate target color data with each sheet.
15. The printer of claim 11 , wherein the target color data includes solids and gray level target data.
