[0001]

This invention relates to a color difference inspection jig for patterned articles.

[0002]

2. Description of the Related Art Conventionally, when managing the color difference of a patterned article such as a decorative board having a colored pattern, there is a machine for projecting the entire patterned article and measuring the color difference, but it is very expensive and cannot be easily carried. There was a drawback. Therefore, it is measured by visual judgment or by a color difference meter (for example, Minolta color measuring instrument CR200) which is widely used.

[0003]

[Problems to be Solved by the Invention] However, when measuring the color difference, the material manufacturer (manufacturing / delivery) side and the receiving side each measure arbitrary locations, so if, for example, light and shade are unevenly distributed like a wood grain pattern, There is a problem in that there are variations in the measured values, and there is a problem due to an error in the measured values between the manufacturer and the receiving side in the pass / fail judgment.

Therefore, an object of the present invention is to provide a color difference inspection jig for patterned articles which can unify the measurement positions and improve color difference management.

[0005]

A color difference inspection jig for a patterned article according to the present invention comprises a color pattern limit sample having a predetermined shape and a standard color pattern of the patterned article, and a color pattern of the color pattern limit sample. And a jig for color difference measurement in which a copy paper on which the surface is color-copied is provided on the upper surface and a plurality of reference holes are formed at predetermined positions.

[0006]

[Function] The color difference measuring jig is placed on the color pattern limit sample so that the color patterns match each other, and the color difference meter is set in the reference hole for measurement. The measured value obtained by this measurement is used as a reference value. Then, on the patterned article for which color difference measurement is to be performed, the color difference measuring jig is also overlaid so that the color patterns are identical to each other, the color difference meter is set in the reference hole, and the measurement is performed. Pass / Fail judgment is performed by comparing with. In this case, since the measuring positions of the patterned articles are unified by the color difference measuring jig, a certain color difference measurement evaluation can be performed on the manufacturer side and the receiving side, and color difference management can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A color difference inspection jig for patterned articles according to an embodiment of the present invention will be described with reference to FIGS. This color difference inspection jig for patterned articles comprises a color pattern limit sample 1 and a color difference measuring jig 2. As shown in FIG. 2, the color pattern limit sample 1 constitutes a part of a decorative board (vinyl chloride laminated board, etc.) having a standard color pattern among patterned products such as cypress pattern, and is handled as an attachment. It is formed in a predetermined shape for easy Using the color pattern limit sample 1, a color difference measuring jig 2 is constructed.

That is, when making the color difference measuring jig 2, first, the color pattern surface of the color pattern limit sample 1 is color copied. Next, as shown in FIG. 3, the color copy copy paper 3 and the mount paper (thick paper) 4 are bonded together (hereinafter referred to as copy mount paper 5). The size of the copy mount 5 is slightly smaller than that of the color pattern limit sample 1. on the other hand,
A punching gauge 7 having the same planar shape as the copy mount 5 and having a plurality of holes 6 at predetermined positions is prepared. Then, as shown in FIGS. 4 and 5, the punching gauge 7 is placed on the copy mount 5 so that the peripheral edges thereof are aligned, the punching jig 8 is fitted in the hole 6 and punched by the hammer 9. As a result, as shown in FIG. 1, a color difference measuring jig 2 having the same color pattern as the color pattern limit sample 1 and having the reference holes 10 formed at predetermined positions is prepared.

Next, the method of using the color difference inspection jig for this patterned article will be described. First, the color difference measuring jig 2 is placed on the color pattern limit sample 1 so that the color patterns match each other.
In this case, the cypress pattern annual ring pattern of the color pattern limit sample 1 arranged on the lower side can be confirmed through the reference hole 10 of the color difference measuring jig 2, or the color pattern limit can be seen from the peripheral portion of the color difference measuring jig 2. It can be confirmed by protruding the sample 1. Then, a color difference meter such as the color measuring instrument CR200 manufactured by Minolta is set in the reference hole 10 to perform measurement, and this measurement value is used as a reference value. Next, the color difference measuring jig 2 is placed on the patterned article for which the color difference measurement is to be performed in the same manner, and the color difference meter is set in the reference hole 10 to perform the measurement. Is compared with a reference value to make a pass / fail judgment.

In this embodiment, since the measuring positions of the patterned articles are unified by the color difference measuring jig 2, a constant color difference measurement evaluation can be performed on the manufacturer side and the receiving side, and color difference management can be improved. it can. In addition, it is rational because it is possible to perform color difference measurement with little error using a color difference meter that is widely used. The jig 2 for measuring the color difference may be provided with the reference hole 10 without using the punching gauge 7.

[0011]

According to the color difference inspection jig for a patterned article of the present invention, the jig for color difference measurement is overlapped on the color pattern limit sample or the patterned article to be subjected to the color difference measurement so that the color patterns of the two match. Thereby, the measurement positions of the patterned articles exposed in the reference holes are unified. Therefore, the color difference measurement and evaluation can be performed on a constant basis on the manufacturer side and the receiving side, and the color difference management can be improved. In addition, it is rational because it is possible to perform color difference measurement with little error using a color difference meter that is widely used.
