[科å°ç½‘() News] The so-called spot color refers to the color printed by a specially formulated ink when printing , not by printing yellow, yellow, black, and black inks. Spot colors are used in prints very much, so regardless of the size of the printing company, regardless of whether there is a professional tinner in the company, the printing equipment operator should learn to manually adjust the ink, otherwise it will be difficult to improve work efficiency. In this regard, the author has a very deep understanding, and now through a successful case of rapid deployment of spot color inks, explain the experience and skills.
Once, our company's four-color machine station printed a batch of printed products using yellow-grey spot colors. The author first carefully analyzed the composition of the spot color ink according to the chromatogram. It is estimated that the ratio of yellow ink, black ink and dilute agent is about 2:1:2, then the yellow group is selected, and the spot color is directly proportioned in the ink fountain. Ink, and evenly apply 50g of black ink and 100g of thinner on the yellow rubber roller, and start the printing and debugging work. When 100 pieces of discarded paper were printed and the crosshair calibration of the plate was completed, it was found that the printed color of the spot color was close to the original, but it was a little deeper, so the author immediately rolled a piece of paper into the rubber roller. After sucking off the excess ink, after re-testing, confirm that the color of the printed product is basically the same as the original, and then officially start production.
After work, the deputy on the machine is somewhat puzzled: Why can I adjust the spot color ink in such a short period of time? Why can I boot directly without cleaning the rubber roller? I believe this is also a question for many printing operators. After a long period of careful study, the author summed up the three essentials of deploying spot color inks, and share them with colleagues.
Feel the heart, "seeing the color"
If you want to match the spot color ink, you must have the ability to "discover color", but this skill is not born, but through the constant understanding of life and work.
In life, always be a thoughtful person everywhere, carefully observe the color changes of various natural scenes, so that your memory of color is more accurate and true. For example, the leaves of spring are light green, the proportion of yellow ink should be more; the leaves of summer are dark green, the proportion of cyan ink should be more; the leaves of autumn and winter are dry yellow, and the proportion of yellow and magenta ink should be more. The proportion of cyan ink should be less.
In the work, we should always compare the colors of various printed products, select the samples that best match the original, the most suitable and the most natural, and retain them for analysis and research, often self-evaluate, and discuss and communicate with colleagues. To continuously improve their color discrimination ability.
If we can persist in this way for a long time, we will be able to practice the "discovering the color" without knowing it. The so-called practice makes perfect, the water drops are worn, the reason is here.
Master the law of ink color change
To master the changing law of ink color, we must learn the basic theory of light color and learn the "basic ten-color map" (including three primary colors, three colors, four complex colors) introduced in the printing professional book. According to the principle of color reduction method, after the three primary color inks are mixed and blended, an approximate black color can be obtained; after the three primary color inks are mixed and mixed in different proportions, various different complex colors can be obtained; after the two primary color inks are mixed and blended, An approximate standard color is obtained; the brightness and saturation of the ink can be changed by adding different proportions of the thinner.
At the same time, it is necessary to accurately grasp the color characteristics of various primary color inks, and to understand the degree of color cast of various primary color inks. Only the impression in my mind is deep. When the ink is blended, the closest and least original ink type can be selected to quickly complete the ink adjustment work. For example, orange red → golden red → red → deep red, the degree of yellowing is getting smaller and smaller; pale yellow → medium yellow → deep yellow → orange, the degree of redness is getting bigger and bigger; hole blue → sky blue → medium blue → product Blue, the degree of redness is getting bigger and bigger.
