  Next, a processing procedure of the image forming system according to the embodiment of the present invention will be described with reference to the drawings. Here, FIG. 6 is a flowchart showing a processing procedure of the image forming system according to the embodiment of the present invention. In the following description, the case of creating download data of color conversion table data for an RGB color image having 9 grids will be described as an example.

  First, the developer first reads the color conversion table data A created by himself (S101), and sets each item of the component Aa for the read color conversion table data A (S102). In the present embodiment, for each item of the component Aa, for example, RGB is set as the input color space, CMYK is set as the output color space, an image is set as the target object, and 9 is set as the number of grids. The setting of these component elements Aa may be directly input on the property screen, or may be read from a file.

  Next, the component data acquisition unit 2 acquires the component Aa from the color conversion table data A acquired by the table data acquisition unit 1, and the validity determination unit 4 inputs the input color, output color, Whether or not the number of grids is not set as a target is checked according to the creation rule B acquired by the creation rule acquisition means 3, and at the same time, the data size of the table obtained from the component Aa and the acquired color conversion table It is confirmed whether the data size of the data A matches, and the validity of the color conversion table data A is determined (S103).

  As a result, when the validity determination means 4 determines that the color conversion table data A is valid, the download creation means 5 adds the management ID to the color conversion table data A and creates download data C (S104). The determination result display means 6 displays the determination result together with the management ID (S105).

  On the other hand, when the validity determination unit 4 determines that the color conversion table data A is not valid in step 103, the determination result display unit 6 determines which component Aa of the color conversion table data A is not the target. Or whether the data size of the table obtained from the component Aa does not match the data size of the acquired color conversion table data A (S106).

  As described above, according to the image forming system according to the above-described embodiment, the illegal data is detected before the color conversion table data A is downloaded, and the creation of the download data C including the illegal data is surely prevented. Therefore, the download data C with high reliability can be provided to the operator. Therefore, it is possible to reduce the mental burden on the operator and the confirmation work, and it is possible to reduce the time required for processing the download data C.

  In the above-described embodiment, when the validity determination unit 4 determines the validity of the color conversion table data A, it is confirmed whether all items of the component Aa are set based on the creation rule B. However, this is merely an example. For example, only the data size is confirmed, or the data size and the input color space, or the data size and the output color space, or the data size and the number of grids are confirmed. Various changes can be made.
