People will inevitably read in their lives to entertain and entertain, but their good mood will always be affected by some fuzzy printing or unclear writing. Occasionally, the writing may be dim and unclear. This is often related to the brightness of the ink, that is, the gloss. So ink manufacturers always use gloss tester to measure. Those who do not understand may have questions about all aspects of the  ink products gloss. Here is a simple science.
      Ink glossiness refers to the ability of a printing sample to reflect the amount of light in one direction when illuminated by light. The first thing we need to understand is the classification of inks, which are mainly divided according to use and solvent composition:
      Industrial inks: printing inks for stationery, paper printing
      Edible ink: mostly used for printing of food packaging, temporary replacement of ink when there is no medicinal ink
      Solvent classification
      UV ink, ceramic ink, glass ink, offset ink, gravure ink, flexo ink
      In view of the difference in the above ink classifications, there are also differences in the requirements for glossiness in practical applications. For example, for newspapers, the gloss of ink is low, because too strong gloss can irritate the human eye, which is not good for reading. For picture books or color printing books, high gloss ink is needed to improve the aesthetic effect of the work. Stimulate the desire to appreciate.

1. Factors affecting ink gloss

(1) Influence of ink properties on ink gloss

The important ingredient in the ink-the binder determines the basic gloss of the ink. The type and nature of the binder generally affect the speed at which the ink enters the paper. The faster the printing speed, the less the amount of binder enters the paper. The gloss of the ink decreases.

(2) Effect of printing conditions on ink gloss

When printing, it is necessary to ensure the surrounding environment and temperature changes. Generally speaking, the higher the printing temperature and humidity, the easier the pores of the paper will be opened. The binder and pigment in the ink will easily penetrate.

(3) The effect of paper properties on ink gloss

As the carrier of the ink, the nature of the paper will affect the ink gloss from another aspect and then affect people's perception. In theory, the smoother the paper, the higher the gloss. If the paper has poor smoothness, the gloss is low.

2. How to detect the gloss of the ink?

This requires relevant practitioners to use the gloss tester LS192 from Linshang Technology for measurement.
