Label Printing Ink

Kagem ink has been paying attention to the label printing market for many years. According to the different quality requirements of cosmetics, luxury and industrial labels, Kagem ink has developed different label water-based ink products. We have accumulated rich experience in this demanding industry and can provide all kinds of bright or matte inks, varnishes or special effect inks for different requirements. With the development of economy, labels are more and more widely used in commodities, which drives the rapid development of label printing industry.

There are many kinds of label printing inks. According to the different solvents used, they can be divided into three categories: aqueous label printing inks, solvent label printing inks and UV label printing inks. The label ink produced by us is safe, hygienic, pollution-free, meets the requirements of environmental protection and is conducive to human health.

Solvent based label printing ink has strong adaptability to label materials, stable performance and high printing quality; However, there are environmental pollution problems, and some volatile solvents are harmful to human body. UV label printing ink has excellent performance, reliable quality and wide application range; However, the price is on the high side, special drying equipment is required, and there are certain requirements for supporting materials. When selecting label printing ink, we should comprehensively consider the types of printing materials, printing methods and printing conditions, special requirements of customers, post printing processing technology, use and use conditions of labels, cost and other factors.

The properties of label printing ink mainly include hue, fineness, saturation, gloss, adhesion, viscosity and dryness. These properties have an important impact on the printing process and printing quality.

During the storage and management of label printing ink, the following problems should also be paid.

Attention to:

1. Safety first, store the ink away from fire and heat source as far as possible to prevent accidents.

2. It is better to keep constant temperature in the ink warehouse, and the temperature difference between the ink warehouse and the printing workshop should not be too great. If the temperature difference between the two is large, the ink should be put into the printing workshop in advance, which is not only conducive to the stability of ink performance, but also ensure the high efficiency of production.

3. In some areas in the north, it is cold in winter. Avoid storing the ink outdoors to prevent the ink from gelling at low temperature. In case of gelation phenomena, transfer it to the warehouse with high temperature or put it into hot water to restore the insoluble matter to its original state.

4. The principle of "first in, first out" shall be followed in ink storage and management, that is, the ink purchased first shall be used first, so as to prevent the ink from affecting its use effect due to long storage time.

5. The ink also has a certain shelf life. If it is stored too long, various components in the ink will separate and precipitate. Therefore, the ink should not be stored for a long time. The general storage period is 1 year.

Viscosity of label printing ink

Viscosity is one of the important quality indexes of water-based ink, and it is also an important factor determining the printing quality. The ink viscosity is too low, which is easy to cause poor transferability, insufficient ink supply, uniform strip of printed products, insufficient amount of transferred ink, white exposure and so on; If the viscosity is too high, the printing text is not clear, the plate is pasted, and the amount of transferred ink is too much, resulting in too thick ink film, which is prone to color fading, ink transfer difficulties and other disadvantages.

The viscosity of label printing ink has generally been standardized in ink products according to the categories suitable for printing, and there is no need to allocate before use. Personalized products can be customized or deployed on site according to the actual situation of users. In the application of ink, some users have a certain misunderstanding about the viscosity of ink. They mistakenly understand that the ink with high viscosity can be diluted in a high proportion, which can reduce the printing cost, resulting in a series of quality defects.

How to eliminate bubbles generated by label printing ink?

The blistering problem of label printing ink has been perplexing the printing ink factory. Due to the serious foaming of label printing ink, the equipment will not operate normally. The equipment manufacturer also added additional attention in the design, but the foaming problem of water-based ink has not been solved perfectly. Nowadays, printing ink factories have been using water based ink Defoamers in solving the problem of water-based ink foaming, because this printing ink defoamer has the advantages of good stability, convenient use, good dispersibility of water, good solubility with water-based ink, little foam removal, less consumption, no influence on film-forming property and no fish eye or needle eye.
