subject: How To Ink Ink Deployment Options [print this page] Any color by hue, lightness and saturation of the three characteristics that result in the matching process must consider these three factors. Although in theory the black is the complete absorption of light, but still glossy printed with black ink. Ink is a pigment (dye) and grinded resin binders, and pigment particles wrapped around a layer of almost transparent resin oil, this oil layer of resin on the light refraction and reflection with the role, so we can feel printed with black ink Print Substrate still has some luster. In the ink color process, according to the actual printing process, ink thickness, printing substrate and other conditions to determine the ink. In the choice of ink, we should consider their own ink gloss, hue, color strength, hiding power.
1. Gloss measuring instrument can only, they can determine with the naked eye, usually in color during the visual observation alone. Gloss actually refers to the ink-like suspension after irradiation direction of reflected light to the same degree of ability to size. Its direct impact on the appearance of printed matter is a very important indicator. At the same time, the choice of ink, the ink to distinguish itself is light, half light or matt inks, to avoid mixing errors.
2. Hue is the color of the basic features, for the qualitative difference. Color, first to consider whether the same hue, the detection method is usually scraping by scraping kind of paper to simulate the color or print, with the eye of standard samples and the samples were observed and compared.
3. Hiding is the ink cover the background level. The worse the better the hiding power and transparency, the transparency of the level of impact on the efficiency and chromatic ink printing substrate by the impact.
4. Ink color strength is that the concentration of a method. The determination is based on a certain amount of ink then add a certain number of standard white ink to dilute the mixture, further comparison with the standard sample method. Color force strength difference reflects the level of ink mixing, affecting the thickness of printing ink.
Identified by the color of paper scraping scraping color color test (Drowdown), the sample can be compared with the standard ink-like in luster, hue, opacity difference between the three areas. Specific method: put the top left corner in the identification of standard ink on paper, color ink top right, between about one centimeter apart around with Scraper Color paper with shaving nearly vertical force flattening the angle of deposition of thin section and gently to rapidly launch angle apply part of the thickness.
The surface to be dried ink, you can apply part of the observation of thin ink hue, ink in the Black Belt part of the identification of hiding power, transparency in the thick part of the judge apply the difference between the gloss and observe the color appearance. Usually black and color ink color with white scratch paper, and white ink is scraped with black and color on paper.
