Abstract

PROBLEM TO BE SOLVED: To provide a method which shortens the time needed confirm a color from toning request time to toning end time. SOLUTION: A 'confirmed-side' spectral colorimeter reads a color to be confirmed and computes spectral reflectance at 16 or 32 discrete points, for example, in the wavelength range (380 to 780 nm) of visible lights (step S101). Then, a 'confirmed-side' computer computes three stimulus values X, Y and Z from the spectral reflectances that the spectral colorimeter has computed. The three stimulus values X, Y and Z which have been computed are transmitted by a 'confirmed-side' communication terminal to a 'confirming side' through a communication line (step S103). When a 'confirming-side' communication terminal receives the three stimulus values X, Y and Z, a 'confirming-side' color printer reproduces the color to be confirmed based on the three stimulus values X, Y and Z (steps S104).

It is necessary for the “color matching request receiving party” to confirm the color requested by the “color matching request ordering side”. Therefore, at this time,
Is the “color matching request order receiving side”, and the “confirmed side” is the “color matching request ordering side”. Also, at the end of the toning request, the “toning request ordering side” needs to confirm the color toned by the “toning request receiving side”. Therefore, at this time, the "confirmation side" becomes the "toning request ordering side", and the "confirmed side" becomes the "toning request receiving side".

Next, from the calculated spectral reflectance R (λ), the spectral colorimeter 201 calculates the tristimulus values X,
Y and Z are calculated (step S102).

The calculated tristimulus values X, Y, and Z are transmitted from the communication terminal 203 to the communication terminal 204 via a communication line (step S103). When the communication terminal 204 receives the tristimulus values X, Y, and Z, the color printer 205 prints the color indicated by the tristimulus values X, Y, and Z (step S).

In the first embodiment, it is not always necessary to use a color printer to reproduce the confirmation color in step S104, but it is sufficient if the confirmation color can be reproduced by a device or method capable of outputting colors. For example, instead of a color printer, a digital color copying machine, a color fax machine, or the like may be used, or the base material may be toned based on the tristimulus value or the Lab value to reproduce the confirmation color. When the confirmation color is reproduced by the toning of the base material, for example, at the time of the toning, the tristimulus values X, Y, and Z of the confirmation color and the tristimulus values X and Difference between Y and Z (hereinafter, color difference) Δ

First, the digital color copying machine 401 reads the confirmation color and the standard color, calculates a tristimulus value (step S301), and outputs it to the communication terminal 402. Here, the correction value calculated by the calculator 404 becomes more accurate as the color of the confirmation color and the color of the standard color are closer, so the standard color read in step S301 is:
It is desirable to be close to the confirmation color. The calculated tristimulus values are transmitted from the communication terminal 402 to the communication terminal 403 via a communication line (step S302).

When the communication terminal 403 receives the tristimulus values,
The computer 404 compares the tristimulus value of the standard color received by the communication terminal 403 with the true tristimulus value of the input standard color to calculate a correction value, and the correction value and the digital color copier 401 From the calculated tristimulus values, a true tristimulus value of the confirmation color is calculated (step S303). For example, the tristimulus values of the confirmation color calculated in step S301 are (X1,

Z1 + (Z3-Z2)).

The color printer 405 prints the color indicated by the tristimulus value output from the computer 404 (step S30).

In the second embodiment, it is not always necessary to use a color printer to reproduce the confirmation color in step S304, but it is sufficient if the confirmation color can be reproduced by a device or method capable of outputting colors. For example, instead of a color printer, a digital color copying machine, a color facsimile, or the like may be used, or the base material may be toned based on the tristimulus values of the check color to reproduce the check color. When the confirmation color is reproduced by the toning of the base material, for example, at the time of toning, the tristimulus value of the color of the base material is calculated from time to time using a digital color copier, This is a method in which the color of the substrate when the difference between the value and the tristimulus value of the color of the toned substrate (hereinafter referred to as the color difference) becomes equal to or less than a predetermined value is regarded as the confirmation color.
