To put it bluntly, the number of color stools will be two or so, or in addition to the main color, a small number of colors will be applied adjacent to each other to produce a color composition.

When the colorful ink is applied before the application, the color that is required to be produced on the color sample is first displayed alone, and the color of the paper (or original) is properly identified as the original color, the intermediate color, and still the complex color. If it is a color, a complex color, it is required to identify the market share of the basic color and the secondary color.

Secondly, it must be adjusted according to the color of the paper, and the sample should be adjusted. When the color difference is small or the same, it can be distributed in a large amount, and the time should be short. The adjustment is less, the production is stopped, the ink color is different, and the production and manufacturing are all carried out normally; too much will cause unnecessary waste.

Ink adjustment is generally carried out in areas where the light source is solid or the light source is not immediately reflected.

Glass ink tinting

Pay special attention to 3 points when screen printing ink color:

a. When adding ink, it is necessary to add less ink of different colors. The lower the color ink type, the higher the mixing effect.

b. Use the "step-by-step" standard, no matter whether you produce light or colorful bright and colorful inks, when the color is close to the pattern, it will not sound. Not the same manufacturer's inks, try not to mix and enable, try to use the same manufacturer's different color ink to carry out the color tone, otherwise it will cause the problem of uneven color, more serious when the agglutination and ink abolish.

c. Some silk screen printing inks are dried by air drying. The light colors are lighter and dry than the undried ones, and the dark browns are deeper after drying.

On the other hand, whether the color of the ink is different before and after drying in the package printing is a problem that is easily overlooked. Under normal circumstances, after the natural dry cognac (organic solvent evaporation ink), the printing process is plastic, metal material, paper type, laminated glass, etc., the color is not easy to change greatly; but if the color used for porcelain, because The coloring agent is only oxidized after the burning air, and only the color is experienced by personal experience. For silk screen printing inks that have undergone thermosetting and light solid drying, the color has changed in shade, as mentioned above. The amount of ink is large, and the ink adjuster can be applied to complete the color tone in a short period of time.

Glass ink coloring knowledge

Petroleum inks are mixed in different market shares and can be used with many colors of ink.

The assignment of light-colored inks is usually dominated by white ink, with appropriate colorful inks. Such as light blue, dominated by white ink, slightly dark blue (cyan); light red, dominated by white ink, slightly increased red; dark gray, dominated by white ink, slightly grayish black; dark gray, dominated by white ink, slightly Add silver paste, plus a small amount of black ink. To produce light-colored silk-screen printing inks (printing materials), it is necessary to add less white ink. Because white ink is specific, it is easy to cause other colors to lose color.
