Problems solved by technology

[0003] The disadvantage of this method is that it is necessary to repeat the above process many times to make the test color film consistent with the sample after aluminum plating, resulting in a lot of waste of manpower and material resources, and the efficiency is very low. Color is more difficult and will reduce efficiency

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 golden aluminum film includes the following steps of (1) detecting the data of the color detecting values for at least more than two different positions on a golden aluminum film sample; (2) calculating the average value of all the color detecting values for the golden aluminum film sample; (3) coating and coloring on a coating color film;(4) padding a special strapwasher under the coating color film and detecting out the data of the color detecting values for at least two different positions on the coating color film;(5) calculating the average value of all the color detecting values of the coating color film;(6) comparing the average value of the color detecting values of the coating color film with the average value of the color detecting values of the golden aluminum film sample and finishing if the average value of the color detecting values of the coating color film and the average value of the color detecting values of the golden aluminum film sample are in an allowable error range, or switching to the step (3). The invention can quickly determine the hue of the golden film for a coating layer, reduce the consumption of manpower and physical resources in vast scale, have a higher effect and can also correct color under the situation that the ray is poor such as at night, etc.

Description

technical field [0001] The invention relates to a color correction method of a golden aluminum film. Background technique [0002] The color correction method of existing golden aluminum film is: 1, white film (coating white film) trial-coating coloring. 2. Take the aluminum film under the test color film and compare it visually with the sample, and repeat the color test until the subjective judgment is that the hue of the test color film after aluminum plating is consistent with the sample. This process is only based on the color test experience of the color matching personnel. 3. Coating and coloring hundreds of meters. 4. Aluminum plating. 5. Take the aluminized film sample and the target sample for visual comparison or color measurement. 6. If there is a deviation, continue to repeat steps 1-5 until the test color film is consistent with the sample after aluminum plating. [0003] The disadvantage of this method is that it is necessary to repeat the above process ma...
