In general, the choice of label printing ink should take into account the types of printing materials, printing methods and printing conditions, the customer's special requirements, post-press processing technology, the use of the label and the use of conditions, costs and other factors.

1, the type of printing materials and performance

The type and performance of printing materials is one of the most important factors in determining label printing inks. Different substrates need different inks. For example, paper labels can be printed using aqueous inks, while film labels are usually printed using solvent inks. In addition, it is worth noting that even the same type of printing materials may use different inks if they have different types, grades or surface properties.

2, printing methods and printing conditions

Printing methods and printing conditions are also one of the important factors affecting the selection of label printing inks. Different types of printing inks generally cannot be used or mixed, and the speed of printing, the type and performance of the printing equipment also have a certain influence on the choice of label printing ink.

3, the customer's request

In the selection of label printing inks, customer requirements must also be fully considered. Sometimes the customer may require the label to have some special effects, such as ice flower effect, sanding effect, anti-counterfeit effect, etc. At this time, it may be necessary to consider how to meet the special requirements of customers and products from the perspective of label printing ink.

4, special process requirements

Does the label have to go through some special processing processes along with the product it is pasting? What are the special requirements? This will also have a certain influence on the selection of the label. For example, in the processing of some products, the label attached to it may be To withstand the test of high temperature, or to contact with certain chemical reagents, this requires the label printing ink must have excellent high temperature resistance, chemical resistance, etc., otherwise it will cause the label deformation or damage.

5, the use of labels and use of the environment

The use of the label and the use of the environment is also a factor that can not be ignored when choosing the label printing ink. For example: the label used on daily chemical cleaning products usually requires its printing ink to have good acid and alkali resistance, oil resistance and the like. Another example: In the outdoor use of the label, due to withstand the wind, sun and rain test, therefore, in the choice of label printing ink must pay attention to the ink in the light, water, high temperature, acid and alkali performance.

6, cost factors

The goal of the company is to pursue the maximization of profits, which inevitably involves cost issues. In general, UV label printing inks have the highest prices, followed by water-based label printing inks, and solvent-based label printing inks have the lowest prices. Of course, the costs and costs of transportation, storage, etc. must also be considered.
