Benefits of technology

The technical benefit described by this inventor lies on quick determination of how much gold-coating will look like compared to previous methods while reducing labor costs or materials usage. This results in more efficient production processes for both good quality products and low cost solutions during poorly lit conditions such as overcast weather.

Problems solved by technology

The technical problem addressed by this patented technology involves how to improve the accuracy and effectiveness of testing gold films without requiring repetitive manual adjustments made during previous processes.

Embodiment Construction

[0017] The color calibration method of the golden aluminum film in this preferred embodiment comprises the following steps:

[0018] 1. The color measuring instrument directly measures the color value of the target sample (golden aluminum film), and measures 5 data at the same time.

[0019] Use L, a, and b to represent the brightness value, red value, and yellow value of the hue, respectively. The larger the L value, the greater the brightness; the larger the a value, the redder; the larger the b value, the more yellow.

[0020] For example: L1=86.66, a1=10.28, b1=50.27; L2=86.38, a2=10.19, b2=50.01; L3=86.66, a3=10.25, b3=49.77; L4=86.50, a4=10.63, b4=50.87; L5=86.64, a5=9.97, b5=49.33.

[0021] 2. Calculate the color measurement average value of the target sample,

[0022] L=(L1+L2+L3+L4+L5) / 5=86.56

[0023] a=(a1+a2+a3+a4+a5) / 5=10.26

[0024] b=(b1+b2+b3+b4+b5) / 5=50.05

[0025] As the color measurement target value in the color matching process.

[0026] 3. The whit...

Abstract

A color correction method for a golden aluminum film, comprising the following steps: (1) measuring data of colorimetric values ​​at at least two different positions on a golden aluminum film sample; (2) calculating the average of all colorimetric values ​​of the golden aluminum film sample (3) Apply color to the test color film; (4) Place a special backing plate under the above test color film to measure the color measurement data of at least two different positions on the test color film; ( 5) Calculate the average value of all the color measurement values ​​of the test coating film; (6) compare the average value of the color measurement value of the test coating film with the average value of the color measurement value of the golden aluminum film sample, if the color measurement value of the test coating film is If the average value of and the average value of the colorimetry value of the golden aluminum film sample are within the allowable hue error range, then end, otherwise go to step (3). The invention can quickly determine the hue of the coated golden film, greatly reduces the consumption of manpower and material resources, has relatively high efficiency, and can also match colors at night when the light is bad.
