Focus on thin film switches!

On the panel layer of the film switch, in addition to children's toys and other decorative strong products on the use of ink color types more, usually there will only be 3 ~ 5 kinds of ink. Although the market can buy a variety of ink has been mixed colors, however, not the color of the ink you need can be purchased in the market, and even if you do, the price may not be acceptable. Usually, film switch manufacturers only buy several main colors (three primary colors and black, white, etc.) back to the factory to deploy their own ink. If the film switch manufacturers can use computer color matching is the most ideal. But more membrane switch manufacturers still use manual color matching process, manual color matching to match the color required by the customer is very difficult or almost impossible. Because, in addition to knowing the theoretical knowledge of ink chromology, toning and matching personnel also need to have rich toning and matching experience, but even if there is a rich toning and matching experience of the "old master" to allocate ink color can only be roughly close to the color specified by customers. Now, what are the differences between traditional matching technology and modern computer matching technology? Artificial traditional color matching: < BR >1: watch the color sample (sample), judge the approximate ink proportion of the color sample according to experience, or check the color card to find the closest color, according to the formula proportion on the color card < br > 2: because of the complexity of color changes, the artificial experience have been the first formula will color difference is very big, partial to the naked eye can see well, but can not be accurately calculated to join, the weight of the ink can only add ink mixing, while allocation side by hand to pressure or by exhibition show color to color machine, less is 3 ~ 5 times, much is to add ink to a dozen times, ink f be, the more time-consuming, laborious and even distribution Without a qualified spot color, the final color difference of the spot color is still not accurate computer color matching control, whether the existence of heterochromia spectrum is impossible to know < BR >(experienced (5 + years) artificial color matching approx. 2.5 hours per spot color) Computer color matching: < br > 1; Measure color sample or standard color card (if it is Pantone spot color call optical data directly from color matching software) < br > 2. Measure printed material, previously used or existing printed material directly call data < br > 3; Selection of ink series used to calculate formula, according to a variety of different conditions filter formula, selection of a qualified formula calculation < br > 4. According to the formula ink type number to join the deployment of samples, adjusted after the display of color machine display color samples, measured by spectrophotometer < br > 5; There may be color difference (generally, the first color difference is about CMC 2:1 de△=1~3.5), and then use color matching software to correct the formula 6; The calculated modified formula is added and measured. Generally, the color difference is about 0.5~1.5 after 1~3 times of correction. In most cases, it has been done (1 month skilled in color matching software, about 0.8 hours on average to match a spot color) < BR > Science and technology is the first productive force, film switch computer color matching with artificial unmatched speed and precision, high reliability, can save a lot of manpower, material and financial resources for the enterprise, can guarantee the quality of your products, can strive for greater space for the enterprise in the new competitive environment!!
