- the measured sample color data is processed and organized.
- the color data of the sample color and the color data of the test coating film are compared, and color matching between the sample color and the test coating film is determined based on a predetermined criterion (color determination step S5). If the color match between the sample color and the test paint film meets the criteria, the work of creating the toning paint is completed, and multiple colors in the toning paint sprayed in the test paint film forming step S3 Are output assuming that the mixing ratio of the primary color paint is the mixing ratio for forming the desired toned paint.
- the provisional primary color paint ratio determined in the provisional ratio preliminary determination step S2 is corrected. (Mixing rate correction step S6). Then, in the test coating film forming step S3, a test coating film is formed again by spraying a toning paint prepared from a plurality of primary color paints on the test panel based on the corrected blending ratio. After that, the color data of the test paint film formed with the corrected toning paint is measured again in the test paint color measurement step S4, and in the color judgment step S5, the sample color matches the corrected test paint color. Sex is determined. In this way, the test coating film formation step S3, the test coating color measurement step S4, and the color determination step S5 are repeated until the determination criterion in the color determination step S5 is satisfied.
- a provisional correction value for the blending ratio of the primary color paint is determined based on the difference (color difference) between the color data of the sample color and the color data of the test coating film. For example, it is possible to obtain a correction value for the mixing ratio of primary color paints by computer color matching (CCM), and it is possible to modify the provisional mixing ratio of primary color paints based on a strong correction value.
- CCM computer color matching
- the toning paint can greatly reduce the number of tonings in the toning work and has very good color matching with a desired sample color. Efficiently obtain Can.
- the test coating film formed on the test panel in the test coating film forming step S3 is formed under substantially the same conditions as the coating conditions in the actual coating process. It is possible to prevent the finish of the paint film from being different due to the difference in the coating conditions with the coating process of the actual product, so the color of the product painted in the actual coating process is equivalent to the sample color. It is possible to efficiently produce a toning paint that becomes a color.
- the difference between the sample color data and the color data of the test paint film corresponds to the difference in the mixing ratio of the primary color paint, and other differences can be eliminated.
- a toning paint having a color equivalent to a desired sample color can be efficiently and reliably produced simply by correcting the blending ratio of the primary color paints of a plurality of colors.
- the cross-sectional area of the coating booth 22 is about 50 cm ⁇ 40 cm is shown. This size is a scale of about lZ 100 with respect to the cross section (about 5m x 4m) of a standard automatic painting booth (standard booth) in the painting process.
- the air whose temperature and humidity are adjusted by the air conditioner 10 (manufactured by Aviste) is supplied to the air supply chamber 21 of the coating apparatus main body 20.
- the air conditioner 10 controls the temperature output and the humidity sensor installed in the air supply duct so as to be in a constant temperature and humidity range while always feeding back the signal output from the humidity sensor.
- the air controlled to a certain temperature and humidity is supplied to the painting booth 22 through the air supply filter 24, resulting in a downflow with an average wind speed of about 0.3 mZsec, and through the dust collection filter 25, Exhaust from the exhaust system installed in 23.
- the transport jig 42 is installed on the dust collecting filter 25 force about 5cm!
- a water-based metallic base paint ("TB-510", manufactured by Kansai Paint Co., Ltd.) is diluted to a coating solid content of 23% by weight and used to obtain a target film thickness (dry film thickness) of 13 to 15 / zm.
- Table 1 shows the coating conditions in the standard booth at each stage for forming the coating film by two-stage coating (flash time of about 2 minutes). Table 1 also shows the coating formation profile conditions.
- the atomized particle size of the spray pattern at the coating distance position according to the above coating conditions is about 21 to
- the atomized particle concentration was about 0.25 cm3 / cm2-min, and the atomized particle velocity was about 7-8 mZsec.
- Table 2 shows the coating conditions for reproducing the coating film formed under these conditions by the coating film forming apparatus 1 according to the present invention.
- the coating conditions shown in Table 2 correspond to the two-time coating conditions with a flash time of about 2 minutes, and it is possible to reproduce the coating film profile conditions in the actual coating process by this condition. .
- coating was performed on a 5 cm x 5 cm test panel under the coating conditions shown in Table 2.
- the amount of paint sample required to form a coating film equivalent to the standard boot was about 12cc.
- the film thickness of (I) is about 12-15 ⁇ m and the IV value is 256-260.
- the film thickness of (II) is about 13-14 m and the IV value is 258-259. It was. In this way, it was possible to reproduce a coating film having a finish almost equivalent to the finish under the coating conditions in the actual painting process.
- IV value is an abbreviation of Intensity Value, meaning brightness, and in a coating film containing a bright pigment, such as orientation of the bright pigment, metallic feeling, etc. It is a characteristic value used as an index. The larger the IV value, the better the orientation of the glitter pigment and the higher the light S.
- the IV value can be measured using, for example, “Alcorp” manufactured by Kansai Paint Co., Ltd.
- Rotation speed 30000rpm (bell diameter: 70mm ⁇ ) Shaving air flow rate: 600nl / min Discharge rate: 240cc / min
- X-axis movement speed 285mm / sec (100mm / 0.35sec)
- Y-axis movement speed 25mm / sec (16mm / 0.65sec)
- the same coating film finish in the actual coating process is used.
- the paint used is a solvent-type silver metallic base paint (“SF420T” manufactured by Kansai Paint Co., Ltd.).
- Table 3 shows the coating conditions in the standard coating process at each stage to form a coating film with a target film thickness (dry film thickness) of 13 to 15 m using two-stage coating (flash time of about 2 minutes). Shown in Table 3 also shows the coating film formation profile conditions.
