The print data transmission system of this embodiment includes a receiver computer 100 for receiving print data and a sender computer 200 for transmitting print data.

As shown in FIG. 1, a receiver computer 100 has a CPU 110 for performing various processes and controls according to a computer program, and an I / O unit for exchanging data and the like with various peripheral devices. 1

The CPU 110 operates as a transmission / reception control unit 111, an input processing unit 112, a display processing unit 113, and a print processing unit 114 by operating according to the computer program described above. The print processing unit 1

8, a color conversion unit 116, and a halftone processing unit 117
And Further, in the hard disk device 170, there are provided user interface data 171 for displaying a user interface for inputting print setting information corresponding to the printer 180, and when performing color correction processing on color image data as print data. The color correction destination data 172 to be used is stored in advance.

On the other hand, the sender computer 200 also has the CPU 210 in substantially the same manner as the receiver computer 100.
, I / O unit 220, memory 230, input device 24
0, monitor 250, communication device 260, hard disk device 270, CD-ROM drive device 290
And

The CPU 210 also operates in accordance with the above-described computer program, so that the transmission / reception control unit 211, the input processing unit 212, and the display processing unit 213
Function as The hard disk device 270 stores color image data 27 that is print data to be transmitted.
1 and color correction source data 272 used when performing color correction processing on color image data as print data.
And are stored in advance.

The color image data 271 stored in the hard disk device 270 is the same color image data as the color image data used for the monitor 250 (that is, the color gamut which can be reproduced on the monitor 250 as described later). , And is composed of, for example, RGB grayscale bitmap data.

Here, the color correction data 172 and 272 used when performing the color correction processing will be described. Generally, in a color space, for example, a color gamut reproducible on a monitor and a color gamut reproducible on a printer are different in size and position from each other. In some cases, the color cannot be reproduced, and conversely, even in the case of a color that cannot be reproduced on a monitor, the color may be reproduced in a printer. Therefore, when trying to print the color image displayed on the monitor with a printer, if the color image is simply printed as it is, the color of the color image obtained by printing is completely different from the color of the color image displayed on the monitor. It will be different.

In order to make the color of the color image obtained by printing as close as possible to the color of the color image displayed on the monitor, a color image used for displaying the color image on the monitor is usually used. The data is subjected to color correction processing (that is, color matching processing), and the printer is caused to print the color image using the color image data after the color correction.

The color correction processing is specifically as follows. For example, assuming that the color image data is RGB data, first, a color image device having an ideal color gamut as a reproduction range in a color space is imagined, and a color that can be expressed in a color gamut that can be reproduced on a monitor. Image data (that is, color image data used for a monitor) RGB is color image data R′G′B ′ that can be expressed in a color gamut that can be reproduced by the virtual color image device.
Is converted using the color correction source data (ie, monitor profile) (RGB → R′G ′).
B '). Next, color image data R'G'B 'that can be expressed in a color gamut that can be reproduced by the virtual color image device
Is stored in color image data (that is, color image data used in the printer) R "G" B "that can be expressed in a color gamut reproducible by the printer, and destination data for color correction (that is, a profile for the printer). (R'G'B '→ R "G" B ").

That is, the color correction source data (monitor profile) shifts all the colors present in the color gamut reproducible on the monitor into the color gamut reproducible on the virtual color image device in the color space. The destination data for color correction (printer profile) is used by the printer to reproduce all the colors present in the color gamut that can be reproduced by the transferred virtual color image device. This is conversion data used for shifting to a color gamut that can be performed.

In the above description, the color image data RGB is converted into the color image data R'G'B 'by the color correction source data, and the color image data R' is converted by the color correction destination data.
Although it has been described that G'B 'is converted into color image data R "G" B ", since the color correction data can be represented as matrix data, the color correction source data and the color correction destination The data may be used to directly convert the color image data RGB into the color image data R "G" B "without going through the intermediate color image data R'G'B '.

By applying the above-described color correction data to the present embodiment, in this embodiment,
Hard disk drive 27 of sender computer 200
The source data 272 for color correction stored in 0 is
Color image data that can be expressed in a color gamut that can be reproduced on the monitor 250 in the sender computer 200 (ie, color image data used in the monitor 250)
This is data (profile for the monitor 250) for converting RGB into color image data R'G'B 'that can be expressed in a color gamut that can be reproduced by the virtual color image device. On the other hand, the color correction destination data 172 stored in the hard disk device 170 of the receiver computer 100 is color image data R ′ that can be expressed in a color gamut that can be reproduced by a virtual color image device.
Data for converting G'B 'into color image data R "G" B "that can be expressed in a color gamut reproducible by printer 180 in receiver computer 100 (ie, color image data used in printer 180) (Profile for printer 180).

The color correction source data 272 is different for each display resolution and other parameters when displayed on the monitor 250. Similarly, the color correction destination data 172 is also provided for each of the print pixel density and halftone processing method (such as dither processing and error diffusion processing), color correction processing method, and other parameters when printing with the printer 180. Are different. Therefore, the color correction source data 272 stored in the hard disk device 270 is
A plurality of color correction destination data 172 stored in 0 are also prepared accordingly.
