Description
Technical Field
The invention relates to the technical field of packaging printing, in particular to a special process capable of enabling offset printing pearlescent ink to be synergistic.
Background
The pearlescent pigment is also called pearlescent material or pearlescent powder, is a special brightness material for improving the added value of products, can improve the brightness of the product color and can also change the color generation effect, and is widely used in the printing industry, the larger the pearlescent particle size is, the stronger the pearlescent powder glossiness is, on the contrary, the smaller the particle size is, the weaker the pearlescent powder glossiness is, the stronger the covering power is, therefore, in order to obtain better visual effect, most of the pearlescent inks adopt pearlescent pigments with thicker particle sizes, and are generally applied to silk screen printing and gravure printing modes, and the offset printing mode is used only in a few special cases without brightness requirements.
The existing printing process is based on the principle shown in fig. 1:
a first part: adding 40-50% of pearl essence into the UV ink fountain oil, wherein the grain size of the pearl essence is less than or equal to 10 mu m;
a second part: after printing color, on-line printing on the ink fountain seat of UV offset press, printing a layer of UV ink fountain oil (the ink amount is about 3 g/m) added with pearl powder by PS plate2) Curing by a UV lamp between the open seats;
and a third part: in the printing machine, the full-plate UV oil or water oil (inking quantity ≈ 5 g/m) is online coated by an anilox roller (general 100 lines)2) The printing paper plays a role in protecting and brightening the printing paper, and the surface of the printing paper presents a visual weak pearlescent effect.
The pearlescent ink with different printing modes is characterized in that:
1. and (3) silkscreen pearlescence: the pearlescent pigment with large particles can be used, the edge is rough, when the surface is irradiated by light, more light can be reflected, the color is enhanced, the glittering effect is generated, the production efficiency is low, the overprinting precision is not high, and the material use cost is increased.
2. Gravure pearling: the pearlescent pigment with larger particles can be used, the reflection effect is better, the production efficiency is high, but the plate-making cost is high, the period is long, and the overprinting precision is general.
3. Offset printing pearlescence: the small-particle pearlescent pigment is used, so that the covering performance is high, the production efficiency is high, the overprinting precision is high, but the reflection effect is weak, and the pearlescent effect is not obvious.
Therefore, it is necessary to provide a special process for enhancing the effect of pearlescent offset ink in the existing packaging printing technology.
