[Problems to be Solved by the Invention]
Appropriate color measurement of patches is necessary to accurately approximate the strong non-linear output characteristics of color printers and printing machines and to create profiles that enable highly accurate color reproduction. An object of the present invention is to reduce the load on the user for acquiring the color measurement result of an appropriate color patch. In particular, the purpose is to facilitate confirmation of whether or not color measurement has been performed properly.
本発明は、カラーパッチを測色することで得られる測色値を取得し、カラーパッチに対応する標準値を取得し、測色値と標準値に基づき、測色にエラーが生じたか否かを判定し、エラーが生じたと判定したカラーパッチをユーザに報知することを特徴とする。 In the present invention, the color measurement value obtained by measuring the color of the color patch is acquired, the standard value corresponding to the color patch is acquired, and whether or not an error occurs in the color measurement based on the color measurement value and the standard value. Is determined, and the user is notified of the color patch for which it is determined that an error has occurred.
また、測色機を用いてカラーパッチを測色することで得られる測色値を取得し、カラーパッチに対応する標準値を取得し、測色値と標準値に基づき、測色にエラーが生じたか否かを判定し、エラーが生じたと判定したカラーパッチを測色機に再測色させることを特徴とする。 In addition, the color measurement value obtained by measuring the color of the color patch using a colorimeter is acquired, the standard value corresponding to the color patch is acquired, and an error occurs in the color measurement based on the color measurement value and the standard value. It is characterized in that it is determined whether or not it has occurred, and the color patch for which it is determined that an error has occurred is remeasured by a colorimeter.
また、互いに色が異なる複数のカラーパッチを測色することで得られる測色値を取得し、複数のカラーパッチそれぞれに対応する複数の標準値を取得し、複数のカラーパッチに対応する複数の許容色差を取得し、測色値、標準値および許容色差に基づき、測色にエラーが生じたか否かを判定することを特徴とする。 In addition, the color measurement values obtained by measuring the colors of a plurality of color patches having different colors from each other are acquired, a plurality of standard values corresponding to each of the plurality of color patches are acquired, and a plurality of color patches corresponding to a plurality of color patches are acquired. It is characterized in that the permissible color difference is acquired and it is determined whether or not an error has occurred in the color measurement based on the color measurement value, the standard value, and the permissible color difference.

【The invention's effect】
According to the invention of claim 1, since the color patch determined that an error has occurred in the color measurement is notified to the user, it is possible to easily confirm whether or not the color measurement result is appropriate, and further, it is inappropriate. The color patch that was the color measurement result can be easily confirmed. According to the invention of claim 8, the color patch determined to have an error can be easily recolored. According to the invention of claim 11, since a plurality of allowable color differences corresponding to a plurality of color patches are acquired, the allowable color difference can be set according to the type of the color patch. Therefore, it is possible to perform error determination according to the importance of the user for each color patch.
