The printing color of light color ink mixing method

Light-coloured ink is to add thinner in the original ink deployment into the ink, or give priority to with white ink add other color is blended into the ink. The match method is thinner or white ink is given priority to, other color is complementary principle, the first scale take appropriate ratio of thinner or white ink, add in and the color, so that side stir uniform ink, observe changes hue, dilute degree is appropriate, by comparing with original paper scraping the ink samples, switch to the right.
Dilute the color from color to distinguish, is divided into primary, three, and multicolor. All with color ink mixing diluent, add in as long as the original color. But if three, multicolor, lack of ink experience, had better look about the original ink deployment into the color of dark ink, then add the thinner.
Mixing light ink, master good ink dilution degree is an important technical link. If the dilution ratio is not enough, will cause the ink roller surface enough ink, the print layout of ink used flowers, dry ink layer is not solid, colour is not bright; If ink diluted too much, only increase the ink layer thickness can achieve printing the color, so that ink paste version, easy to make the layout of a low profile area appears confused depth level. At the same time, also easy to cause print bottom phenomenon.
Deployment of light-coloured ink according to product quality requirements, and the characteristics of paper, choose appropriate to the ink and thinner. Such as offset paper printing ink printed general with 10 products, can choose thinner 915 (d), or 554 transparent oil.
If printing coated paper adopts 05 type ink printing fine products, should choose 05-90 light pulp removed light agent or 8011, 8015. Blending light-colored ink should also note that for light resistance, oxidation resistance, easy to change color of the original ink, try to avoid to allocate light color, lest cause the color is not stable.
In addition, because white ink than major, in addition to have covered the requirements and need to color and a small amount of add some used to invoke, as far as possible don't have white ink diluent. In order to prevent weight problems such as improper folding color, rub off.
When the deployment of ink, but also should pay attention to the proportion of different ink, such as the use of lead chrome yellow ink than major and peacock blue with green ink, put for a long time, so the "floating color", if the use made of organic yellow pigment yellow ink to deployment, won't appear the phenomenon.
To sum up, only to learn to master color knowledge and understanding of printing ink, auxiliary materials relevant situation and use characteristics, to scientifically allocate out all sorts of color, in order to meet the requirements of improving printing quality and production efficiency.
