Problems solved by technology

The first problem is that since the user's printing conditions (combination of printer and paper) are not known, the amount of colorant that can be absorbed by the paper that is the target of image printing, that is, the amount of colorant such as ink, cannot be properly controlled.
The second problem is that the color development characteristics of the paper are not known, so the optimal color separation cannot be achieved taking the color development characteristics into account
The third problem is that the image cannot be printed in the satisfactory color expected by the user
[0011] However, with the prior art, since the color development characteristics of the paper whose profile is not prepared are not known, and optimal color separation cannot be achieved, there is a possibility that the printing effect matching the paper cannot be reliably achieved, and there is also the possibility that the Possibility to print images in the colors desired by the user

[0043] Now, a first embodiment of the present invention will be described with reference to the drawings.

[0044]1 and 4 are block diagrams of an image printing system according to a first embodiment of the present invention. The image printing system includes: a PC 101 for controlling; an image display device 102 such as a monitor for displaying images; and an image forming device 103 such as a printer for printing images. Reference numeral 104 denotes a test chart printed by the printer 103 using paper on which the user wishes to print an image. The test chart 104 is, for example, a printout of printing image data in 9 levels (729 colors in total) in each of RGB. Here, it is required that the image data can provide color reproduction characteristics under the printing environment (including printer and paper) where the user wishes to print the image. The image printing system further includes: a profile server 105 for sending a printer profile to a printer driver through ...

[0074] When professional photographers and painting and calligraphy artists utilize large-scale printers (represented by 805 in FIG. 8 ) to produce works, if they repeatedly print dozens of printed products according to the trial and error method, the cost of paper will be significantly increased, and the printing time will be prolonged. Utilizing the second embodiment of the present invention, by first using a small-format printer (indicated by 803 in FIG. 8 ) to generate a reduced work, and then profiling the large-format printer, the same color reproduction as the small-format printer is guaranteed. steps to avoid this problem.

[0075] Next, a second embodiment will be described with reference to FIG. 8 .

[0076] Fig. 8 is a block diagram of an image printing system according to a second embodiment of the present invention. This image printing system includes a PC 801 for control, which is the same as the PC used in the image printing system according to the first embodi...

[0079] The third embodiment of the present invention can easily form a profile that can provide the color reproduction characteristics of the paper that the user usually uses when another paper is used. Next, a third embodiment will be described with reference to FIG. 9 .

[0080]Fig. 9 is a block diagram of an image printing system according to a third embodiment of the present invention. This image printing system includes a PC 901 for control, which is the same as the PC used in the image printing system according to the first embodiment. In addition, the image printing system further includes: an image display device 902, such as a monitor, for displaying images; and an image printing device 903, for example, a printer, for printing images. Reference numerals 904 and 905 denote test charts printed by the printer 903 in cooperation with different types (A and B) of paper required by the user to finally print images. The test charts used in this third embodiment are respec...

Abstract

A profile forming method includes a category obtaining step of obtaining a category of a printing medium, a profile obtaining step of obtaining a profile corresponding to the category of the printing medium, a total colorant amount obtaining step of obtaining a total colorant amount corresponding to the printing medium, and a profile forming step of forming another profile adapted for the printing medium based on both the profile obtained in the profile obtaining step and the total colorant amount.

Description

technical field [0001] The invention relates to a profile forming method and a printing system. Background technique [0002] The widespread availability of digital still cameras and scanners has increased opportunities for users to print images for artistic appreciation and long-term preservation. Therefore, there is an increasing demand for printing images in higher-quality colors. In addition, for example, since higher resolution and higher precision printers suitable for printing on large-sized paper have been developed, professional users such as calligraphers and photographers have increased to employ printers as tools for producing works of art. These professional users produce works using various (types) of paper including fine art paper and thick paper. In order to meet the demands of these professional users, printer manufacturers have increased the number of paper types specifically for that printer. [0003] However, it is very difficult for printer manufactur...
