Abstract
A printing system includes a terminal device, a plurality of printers, a first server, and a second server. The first server calculates a round-trip accuracy of each printer using a color conversion profile supplied from the second server with respect to target color information included in a printing command provided from the terminal device, and selects one or more printers among the plurality of printers according to the round-trip accuracy to cause the printers to execute printing.
Claims6
A printing system constituting a network, comprising:
- a terminal device;
- a plurality of printers;
- a first server that receives a printing command including image data to be used for printing and target color information indicating a target color for color reproduction from the terminal device, and selects one or more printers among the plurality of printers according to the printing command to cause the printers to execute printing;
- and
- a second server that stores a color conversion profile indicating color reproduction characteristics of the plurality of printers, wherein
- the first server includes
- a calculation unit that calculates a round-trip accuracy with respect to each printer of the plurality of printers using the target color information and the color conversion profile supplied from the second server, and
- a selection unit that selects a printer to be used for printing according to the printing command depending on the round-trip accuracy, and
- the calculation unit executes
- (a) processing for obtaining a first color value indicating the target color in a device-independent color system from the target color information,
- (b) processing for converting the first color value into a second color value using a first color conversion profile for converting a color in the device-independent color system into a color in a device-dependent color system of each printer, and a second color conversion profile for converting a color in the device-dependent color system of each printer into a color in the device-independent color system, and
- (c) processing for determining a color difference between the first color value and the second color value as the round-trip accuracy.
A printing method using a printing system that constitutes a network and includes a terminal device, a plurality of printers, a first server that selects one or more printers among the plurality of printers according to a printing command provided from the terminal device to cause the printers to execute printing, and a second server that stores a color conversion profile indicating color reproduction characteristics of the plurality of printers, the method comprising:
- (i) receiving a printing command including image data to be used for printing and target color information indicating a target color to serve as a target for color reproduction from the terminal device by the first server;
- (ii) calculating a round-trip accuracy with respect to each printer of the plurality of printers by the first server using the target color information and the color conversion profile supplied from the second server;
- and
- (iii) selecting a printer to be used for printing according to the printing command depending on the round-trip accuracy by the first server, wherein
- the step (ii) includes
- (a) obtaining a first color value indicating the target color in a device-independent color system from the target color information,
- (b) converting the first color value into a second color value using a first color conversion profile for converting a color in the device-independent color system into a color in a device-dependent color system of each printer, and a second color conversion profile for converting a color in the device-dependent color system of each printer into a color in the device-independent color system, and
- (c) determining a color difference between the first color value and the second color value as the round-trip accuracy.
