On the panel layer of the membrane Switch , in addition to the variety of ink colors used in such decorative products such as children's toys, usually the ink has only 3 to 5 colors. Although a variety of inks that have been formulated with good colors can be purchased on the market, not all the inks of the color you need are available on the market.
Even if you buy them, the price may not be accepted. Usually, the Membrane Switch Manufacturer only purchases inks of several main colors (three primary colors, black and white, etc.) and returns them to the factory. It is ideal if the Membrane Switch manufacturer can use a computer to match colors.
However, many membrane switch manufacturers still use manual color matching technology. It is very difficult or almost impossible to manually match the color to match the color required by the customer. Because, in addition to understanding the theoretical knowledge of ink color science, the color of the color matching personnel also needs to have rich experience in color matching, but even the color of the ink that the " master " with rich experience in blending colors can only approximate.
It is close to the color specified by the customer. Now let's analyze the differences between the traditional color matching process and the modern computer color matching technology.
Artificial traditional color matching:
1. View the color sample (sample), judge the approximate ink ratio of the color sample according to experience, or check the color card to find the closest color, and mix according to the formula ratio on the color card.
2. Because a large color change of complexity, the initial human experience obtained formulation chromatic aberration, the naked eye can see the color shift, but cannot accurately calculate the weight of the ink to be added, while adding only ink formulations while stirring for hand pressure-spreading or color stripe color development machine, at least 3 to 5 times, as much as ten times to increase the ink, the ink is transferred, the more time-consuming, even with no qualified spot color, the spot color with the last The color difference is still not as accurate as the computer color control, and it is impossible to know whether there is metamerism.
(Experienced (more than 5 years) artificial color matching is about 2.5 hours a spot color)
Computer color matching:
1. measurement color sample or standard color card (if Pantone spot color directly calls optical data from color matching software)
2. Measuring printed materials, previously used or existing printed materials directly call data
3. Select the ink series to calculate the formula, filter the formula according to various conditions, choose a calculated qualified formula
4. Add the matching sample according to the number of formula inks, adjust the sample with the color display machine, and measure with the Spectro densitometer
5. The data of the sample may have a color difference (generally the first color difference is in CMC 2: 1de △ =1~3.5), and then the formula is corrected by the color matching software.
6. Calculated corrected recipe added good allocation measurement, generally after color difference correction in 1 to 3 times of about 0.5 to 1.5, in most cases it has
(The color matching work of the color matching software for 1 month is about 0.8 hours with a spot color)
Science and technology are primary productive forces, membrane switch computer matching with artificial unattainable speed and accuracy, high reliability, can save a lot of manpower and material and financial resources for the enterprise, to guarantee the quality of your product, for enterprises in the new competitive Strive for more space in the environment.
