spiral yo book printing in color printing will have a special term called neutral gray balance, gray balance refers to the yellow, magenta and blue three color plates according to the different proportion of the total area of business outlets in the printing material into neutral gray. This is called neutral grey equilibrium, let's go to understand its other professional knowledge.

What are the provisions of neutral gray balance for ink?

1: High clarity: When the ink is sized into a symmetrical plastic film, the level of the background color of the chemical substance bearing the ink film, the clearer the background color indicates, the higher the clarity of the ink.

2, fine pigment particles: fine pigment particles for fine packaging and printing goods.

3, good coloring power: the coloring power of the ink is a quantity that indicates the compressive strength or content of the color of the ink, for the same color of the ink, the coloring power depends on the particle size distribution of the pigment on the interconnecting material, the higher the particle size distribution, the stronger the coloring power; It will also lie in the composition of the pigment, the higher the composition, the stronger the coloring power.

4, light resistance: under the effect of light, the color of the pigment will fade and fade at different levels, which is also a characteristic of light resistance.

5, color rate: color rate is a comprehensive index value of ink color and gray level.

6, good organic chemical stability: the color of the ink can be changed under the effect of some compounds, therefore, the ink has good organic chemical reliability, moisture resistance, corrosion resistance, resistance to Z alcohol and other characteristics.

Know the point below to explain the function of printing paper and neutral gray balance correlation

Different types of printing paper for the same ink coloring ability is a great difference, like screen printing common copper paper and coated paper for the three primary color ink gray balance of the main parameters are not the same. The fineness, smoothness, speed, smoothness, opacity and ph of the printed paper are also a major element of the harm to ash balance. The fineness of the white newspaper commonly used in colorful newspaper printing is very low and dark, and the information of its packaging and printing gray balance is greatly different from that of copper paper and coated paper.

Understand the neutral gray balance in color printing, know its needs and the association between printing paper and it, and pay more attention to it if it is effective in printing to prevent frequent errors and omissions, resulting in damage.
