The use of pearl printing technology skills

Pearl printing technology is in recent years in the label printing and packaging and printing of the more popular a new anti-counterfeiting printing technology, his master If use pearl ink. Pearl is a pearl luster ink ink, when print pattern change Angle, will change the color of the ink, from And can identify authenticity.

  The use of pearl printing technology skills

  1, the relationship of pearl pigment between the diameter size and flash effect. Used in packaging and printing is the pearl pigment in the plate shaped, usually diameter is flash Source is, the distance between flash effect; On the other hand, the piece of small diameter, flash source spacing is small, flash effect is concentrated.

  2, the relationship of pearl pigment between the diameter size and intensity of flash. Pearl pigment piece of the larger the diameter, and its surface by multiple reflection, refraction to the light more, the intensity of the flash is stronger; On the contrary, the strength of the flash is weak.

  3, pearl pigment diameter size and the cohesion and the link of the relationship between the suspended settling. Usually diameter yue xiaoyue easy condensation, the piece of pearl pigment Grain of aspect ratio of the smaller, thus in the links of material also prone to settlement, otherwise easy to a slurry.

  In order to make the paint evenly dispersed in the link of material, must be on the basis of mastering the three relations, according to link of material to choose the suitable diameter and density of vertical and horizontal Than pearl pigment. In the deployment of ink, can also by adding thickener to prevent the settlement of pearl pigment; Or scatter again after pearl pigment wetting in advance Links in the material, it also can avoid to produce particles condensed cluster and settlement.

  Pearl ink mixing method is:

   (1) generally, per 100 g ink to add 10 to 20 g of pearl pigment;

   (2) the pearl pigment directly with this link material in a ratio of 1:1, conform to the requirements of the printing ink flow concentration;

   (3) mixing color pearl ink can also add some trace organic pigments in order to reduce costs. Generally adopt the method of white pearl pigment with other pigments , such as adding 1% carbon black in the white pearl pigment, you can get the ancient silver effect.
