Abstract

The invention discloses a pearlescent ink which is especially used for intaglio printing of light-color substrates. The pearlescent ink is mainly prepared from the following raw materials in parts by weight: 25-65 parts of nitrocellulose resin liquid, 8-25 parts of pearlescent powder I, 3-12 parts of pearlescent powder II, 2-8 parts of pearlescent powder III, 0.1-3 parts of wetting and dispersing agent, 0.1-3 parts of anti-settling agent and 5-40 parts of n-propyl ester. Correspondingly, the invention also discloses a preparation method of the pearlescent ink and a printing method of the pearlescent ink. The pearlescent ink can satisfy the requirements for intaglio printing on light-color substrates, and has favorable printing effect.

Description

technical field [0001] The invention relates to the field of inks, in particular to a pearlescent ink, a preparation method and a printing method thereof. Background technique [0002] Pearlescent pigments are widely used in the printing of various packaging materials due to their soft and shimmering effects, but due to their light color and poor hiding power, it is difficult to print solidly on light-colored substrates (the so-called surface printing effect is "faint". The phenomenon). Therefore, it is necessary to print a thick and full pearlescent effect on light-colored substrates, which is usually achieved by thicker roller coating or screen printing, while thinner gravure printing is rarely used. In particular, the existing screen printing effect needs to be realized by gravure printing, which is more difficult. [0003] That is, the existing pearlescent ink cannot meet the requirements of gravure printing on light-colored substrates, especially the requirement that ...
