As a color matching proofing technician, you should have a sufficient understanding of the types and properties of textile fibers and textiles, the selection of corresponding dyes, the basic properties of the selected dyes such as shade, hue, and strength, as well as the dyeing process corresponding to textile fibers. The effect of color matching between dyestuffs and the precautions when adjusting colors are fully understood, so that the dyes used can be correctly selected as soon as the samples are received from customers, and qualified dyeing formulas can be given in time to ensure The production was carried out in a timely and smooth manner.
Training of basic abilities
For a color matching proofing worker who has just entered the industry, he should first receive basic proofing ability training. The basic training is mainly divided into two steps: the production of the dye monochrome sample card and the production of the three primary color color matching pagoda map of the dye.
1 Production of monochrome sample card
Select a dye, dye the same grams of grey cloth according to a certain concentration gradient, cut out square pieces of dyed cloth and stick them on the card prepared in advance, and do this operation with all the dyes used in the proofing room After stringing together, you can get a single color sample card of the dye. Making a single-color sample card for dyes can help newcomers to understand the types of dyes used in the proofing room, the color light of the dyes, and the changing law between the color light and the dye concentration, which is conducive to the color matching.
2 The production of the pagoda diagram of the three primary colors of dyes
When making a three-color color matching pagoda diagram, a fixed dye concentration (such as 1% o.w.f) should be set first, and then starting from the three corners of the triangle, reduce or increase the dye according to a 10% concentration gradient along the three sides. Concentration, and calculate the content of the three primary color dyes at each position, the statistics can obtain a total of 66 samples of the three primary color matching pagoda map. After dyeing the cloth sample, cut out the fixed shape and paste it on the corresponding position of the pagoda map.
