subject: Deployment Of The Basic Principles Of Color Ink [print this page] Whether dark or light color ink, the allocation should follow the basic principles, the basic principle is based on science and color printing based on printing technology. The main contents include the following ten points:
(1) as far as possible with the same type of ink and type of supporting material. In addition, two primary color inks can be used to deploy into the use of three primary colors is not the color of ink. Similarly, if the need for some inter-color matching, and also between the color with the original ink, so as not to reduce the brightness of ink, affecting color and brightness. Deployment of dark ink, the ink in accordance with the weight of the primary color ink into the ink transfer tray, and then gradually add complementary colors and the necessary supporting materials.
(2) Where the agent to dilute the main, secondary colors, or dark ink, the ink deployed collectively referred to as light-colored ink. Light-colored ink and transfer method to deploy in the dark ink is slightly different light color ink in the ink gradually joined the dark. Cut can not first get together after dark ink light ink, because the light-colored ink color is weak, if the light in the dark ink in the ink by adding methods to deploy easy alignment hue, often make more ink more tone.
(3) deployment of deployment of spot-color ink before a small sample. It is said that the initial judgments based upon the hue of the ink color to be used, and then in proportion to the balance from the colored ink used to take a little ink, said, accurately weighed, placed in the deployment stage, even after the transfer ink, scraped with a scraper and a small color samples stood inspection, and make relevant records be kept.
(4) deployment of complex color spot color ink, the use of complementary color theory correct the color cast. For example: when a color ink in the purple complex flavor emphasis, it can be corrected with yellow ink; if the emphasis on flavor of red, blue ink can be added (such as peacock blue or sky blue ink) to correct; Another example is printed with black ink yellowish blackness not enough, they can shoot light blue with small amounts of pigment, as mentioned, because the radio light blue is blue with red ink, printed with black ink will help improve the blackness.
(5) control the hue characteristics of ink used. In actual operation, we must grasp the common characteristics of ink hue. For example, Lake in the deployment of light green ink, the appropriate use of sky blue or peacock blue, should not have to deploy with a dark blue, dark blue ink with red because of taste, after adding the color gray but not necessarily bright, the same token, nor can use the deep reddish yellow ink, while the blue side of the yellow ink with good effect, another example, the deployment of orange-red ink red ink as far as possible to use gold because the gold hue of red ink is red yellow light, bright increase the level of ink. In addition, some inks used to be according to the picture effect, such as portraiture and landscape printing ink selected should be different.
(6) Note that the proportion of different ink. The proportion of ink in general is different, the proportion of similar ink easy to mix, while the proportion of the huge difference will cause the printing ink spacious disease, for example, with the proportion of lead chrome yellow and peacock blue ink ink ink deployment of green, put for a long time, the proportion of small color ink will go up, than the major who will sink, so there "floating colors" spacious disease. If the use made of yellow pigment ink to deployment, the spacious, there is no disease. Besides, given the proportion of white ink, in addition to covering the requirements and need a small amount of color add some things, try not to use white ink diluted (if Film is another matter of live parts) to prevent overlapping color bad, fade and other quality problems.
(7) reasonable choice of diluent to dilute the degree to master. When the hue and the use of ink is determined, must be a reasonable choice diluent, such as offset printing paper and coated paper used in different diluent. In addition, it is important to dilute the degree of technical aspects, if the dilution ratio is small, easy to blur the surface of printing, ink is not really shriveled, color is not bright; if the ink is too powerful to dilute, only to increase the printing ink to achieve the required thickness of Hue This low-key region of the layout is easy to paste version, which can not distinguish the depth level. At the same time, the phenomenon will occur through India. Also, for non-light-fastness, tiring easily oxidized to avoid discoloration of the original ink for the deployment of light-colored ink, so as not to cause color instability.
(8) deployment of spot-color ink scraping like paper and printing paper to be consistent, avoid paper of different colors caused by differences.
(9) deployment of spot-color ink density when the same kind of attention and India. In general, when just tuned the new ink-printed with the offer of the color close, when the new ink color change will occur after drying, so just tuned the new ink in color printing can not be light at the sample.
(10) both finishing characteristics. Select ink, consider finishing, and if printed materials need to polish, you can select general printing ink, printing ink if you choose a good abrasion resistance, not only cost, but also affect the polishing effect.
