Dilute ink to help you solve the problem of printing color

Some packaging and printing companies often have inconsistencies in the hue before and after the printed product. The probability of problems in the yellow, magenta, and blue primary inks is relatively small, and the problem often arises from some spot color inks that the user requires, such as complex colors. , Including light gray, light brown or dark tea, dark green, dark brown and other colors, some colors are the same when printed, so after a few days the ink will change, appear color cast, different shades, Problems such as lack of coverage. The main reason for this situation is that the ink brands used in printing plants are more complex, and some printing factories do not have colorimeters or reflective densitometers. They use three basic color tones, such as magenta, sky blue and medium yellow, and the ratio is inaccurate. . Moreover, the production conditions of the plants are different, the raw materials are not the same, there will be errors in the hue, such as magenta, some purple, and some red; another example is sky blue, some reddish, some greenish Medium yellow, some reddish, some greenish.

Dilution of the diluting agent used by the ink and the brightening effect of the bright paste are inconsistent. Diluting with the white ink improves the hiding power and makes the color shift more likely to occur.

Should pay attention to the use of ink orientation management and calibration, it may reduce the occurrence of the above situation.
