At the same time as checking according to the acquired creation rule B, it is checked whether the data size of the table obtained from this component Aa matches the data size of the acquired color conversion table data A, and the color conversion table data A The validity is determined (S104). When the developer selects new creation in step 103, although not shown in particular, the download ID C is created by adding the management ID to the color conversion table data A, and this processing is terminated.

  As a result of the determination in step 104, when the validity determination means 17 determines that the color conversion table data A is valid, the sample data reading means 21 determines whether there is a confirmation sample (S105). If there is a confirmation sample, the confirmation sample is read (S106), and confirmation data D is created (S107). If there is no confirmation sample, confirmation data D is created without reading the confirmation sample (S107).

  On the other hand, when the validity determination unit 17 determines that the color conversion table data A is not valid in the step 104, the determination result display unit 19 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 (S108).

  Next, with reference to FIG. 10, a processing procedure when performing a confirmation operation in the image forming system according to the embodiment of the present invention will be described.

  Next, the sample data reading means 24 determines whether there is a confirmation sample (S203). If there is a confirmation sample, the sample data reading means 24 reads the confirmation sample (S204). Advances to the next step 205 without reading the confirmation sample.

  In step 205, the data comparison means 25 determines whether or not the confirmation data D and the data body of the download data C match (S205). As a result, when the data comparison unit 25 determines that they match, the comparison result output unit 26 outputs a comment (check data) indicating that both data match (S206). At this time, if it is determined in step 203 that there is a sample for confirmation, the sample is also output at the same time.

  On the other hand, if the data comparison means 25 determines in step 205 that the confirmation data D and the data body of the download data C do not match, the comparison result output means 26 gives a comment that both data do not match. The confirmation data D including (check data) and the data body of the download data C are output together with version information and identification information of the download data (S207). At this time, if it is determined in step 203 that there is a sample for confirmation, the sample is also output at the same time.

  As described above, according to the image forming system according to the above-described embodiment, whether or not the data body of the color conversion table data A desired by the developer is used can be confirmed by the confirmation data. Download data C can be provided, and the time required to correct the download data C can be shortened and the cost can be reduced.
