The deployment of ink is an important task in the color printing process. How this work is done is directly related to the printing quality of the product. Because the color is bright, the brightness is good, and the hue is accurate is the basic requirement of the color printing product, in order to realize this requirement, the printing ink must be well-distributed. Therefore, the operator must master the color knowledge and the ink transfer process.
First, we must master the changes in the three primary colors in order to achieve accurate ink deployment We know that any color can use the three primary colors mixed with different proportions. The hue of ink changes, it is to use this rule. If the three primary inks are mixed in equal amounts, they can become black (approximate). Tricolor inks are mixed in the same amount and added with different proportions of white ink to be formulated into light gray inks of various shades. If the three primary inks are blended in various proportions, they can be blended into a variety of different hue inter-colors or complex colors, but their hue is biased towards a large proportion of the primary color hue. If the two primary inks are mixed in the same amount, they can become standard inter-colors; after the two primary inks are mixed and mixed in different proportions, they can be mixed into a plurality of different hue inter-colors, but their hue tends to a large proportion of the primary color hue. In addition, in any color ink, the hue becomes brighter after adding the white ink. Conversely, after adding black ink, the hue becomes dark. The above-mentioned use of primary color inks to prepare a variety of colors is based on the theory of subtractive color of three primary colors.
Second, when the ink transfer should first analyze the hue of the draft, and use the complementary color theory to correct the color cast, improve the setting effect. When receiving the print, first of all, the various colors in the manuscript should be seriously appreciated and analyzed. The proportion of ink hue to be adjusted. The analysis of color drafts is to grasp a basic principle, that is, the primary colors are to match any black basic color. In general, applying the changing rules of three primary colors, in addition to gold and silver colors, any complex color can be deployed. However, in the process of the process, it is not enough to rely on the three primary colors of ink to deploy an unlimited number of ink colors. Because, in fact, because the pigments used to make inks are not very standard, even each batch of ink produced will inevitably have a certain degree of difference in color. Therefore, in the actual work, the color inks such as medium blue, dark blue, light blue, light blue, medium yellow, dark yellow, light yellow, gold red, orange red, dark red, light red, black, and green should be added. In order to achieve the desired ink hue. There are many kinds of ink, but in any case, other than the three primary colors, other colors are used to supplement the deficiencies of the three primary colors. Any complex color is always changed within the scope of the three primary colors. As long as this principle is mastered, the transfer of ink will not be a problem. When the color analysis determines the main color and the auxiliary color ink and this example, it can be prepared. However, if there is a deviation in the hue allocated, the complementary color theory can be used to correct the hue. For example, a hue with a green hue can be corrected by adding a small amount of red ink. On the contrary, the red taste is too heavy to be corrected by adding blue ink.
Third, the deployment of the color and complex color The so-called inter-color, is the mixture of the two primary colors ink mixture. Such as: the color of the color is red and yellow after the hue is orange; yellow plus blue can get green; red and blue can become purple. Different proportions of the two primary colors can be mixed and mixed, and many kinds of inter-colors can be prepared. That is, the primary colors of pink and yellow are mixed with 1:1 to obtain a large red phase; if they are mixed with 1:3, dark yellow can be obtained; if they are mixed with 3:1, a reddish phase can be obtained; if the primary colors are yellow and blue, etc. Mixing quantity can get green color; if you mix with 3:1, you can get emerald green color; if you mix with 4:1, you can get apple green; if you mix with 1:3, you should get dark green. If the primary colors of pink and blue are mixed in a 1:3 ratio, a deep blue-purple color can be obtained; if the color is mixed with 3:1, an approximate color of pink can be obtained. The complex color is derived from the mixing of three primary inks. If they are mixed in different proportions, many kinds of complex colors can be obtained. For example, the primary colors of pink, yellow and blue can be similarly adjusted to obtain approximately black; 2 parts of pink and 1 part of yellow and blue can be mixed to obtain brown red; 4 parts of pink can be mixed with yellow and blue to obtain red. Brown phase; if the pink, yellow, 1 and 2 blue, can be transferred with olive; 1 pink, yellow, 4 mixed with blue, get a single room green hue, and so on.
Fourth, deployment of black operation essentials When deploying ink, according to the original analysis of the hue, determine which ink should be used to deploy the appropriate. For example, to adjust the lake blue ink, based on visual experience and practical experience, it can be determined that white ink and peacock blue should be mixed and blended. White ink is the main color, and peacock blue is the auxiliary color. If you want to deeper, you should add more blue. If you want to adjust the olive yellow-green ink, you can determine the main white ink, add light yellow and peacock blue and slightly pink can be. As long as the main color is determined, the other colors are auxiliary colors, which should be added gradually and gradually and evenly. Afterwards, use two pieces of paper (same as printing paper), one of which is coated with a little of the adjusted ink, and the other paper is used to scrape it to the thickness of the printed ink, that is, if it is compared with the original. . When comparing samples, it is necessary to look at the relatively thin and light parts of the ink layer on the paper surface in order to see accurately. To adjust the ink, one must also master a principle, that is, use less different colors of ink, that is to say, can be tuned with two kinds of ink, do not use three kinds of ink to adjust, so as not to reduce the gloss of the ink. On the other hand, scraping crickets is slightly more rigorous than the original color, so that the printed color swatches can be more accurate. After the sample's ink hue is quasi-premeditated, it can be batched to adjust the ink according to its respective proportion of ink, so as to ensure the quality of the ink transfer and improve work efficiency.
To sum up, as long as we master the changing laws of the three primary colors, apply good knowledge of color, and practice and analyze it, we can quickly and quasily deploy excellent colors that are accurate, colorful, bright, and printable. Ink, lay a solid foundation for improving product quality. (Author: Kang Qilai, Printing Factory, Putian County, Fujian Province)

The most common types of couches are the two-seater, designed for seating two persons, and the sofa, which has two or more cushion seats.A Couch consists of the frame, the padding and the covering. The frame is usually made of wood but can also be made of steel, plastic or laminated boards. The wood used under the upholstery is made from kiln-dried maple wood that is free of knots, bark or defects. The show wood of the legs, arms and back can be maple, mahogany, walnut or fruitwoods. Sofa padding is made from foam, down, feathers, fabric or a combination thereof. Sofa coverings are usually made out of soft leather, corduroy or linen fabric coverings. Some outdoor sofas are made from specialist reticulated foam. Due to its highly advanced open cellular structure, water freely passes through it making it highly resistant to soaking.Many modern sofas are filled with fibre cushions or low density foam. This is largely due to a massive cost saving by the manufacturer in using a fibre material rather than a solid foam cushion.
