  There are many types of label printing inks. Depending on the solvent used, they can be classified into three main categories: water-based label printing inks, solvent-based label printing inks, and UV-curable label printing inks.

  ⑴ Water-based inks are safe, hygienic, and non-polluting, meeting environmental protection standards and promoting human health; however, they also have drawbacks, such as slow drying, limited color saturation, and poor stability. They are not suitable for printing large solid areas, and prolonged storage may lead to sedimentation and layering.

  (2) Solvent-based label printing inks exhibit strong compatibility with various label substrates, offer stable performance, and deliver high print quality; however, they pose environmental concerns, and certain volatile solvents can be harmful to human health.

  ⑶ UV label printing inks exhibit excellent performance, reliable quality, and a broad range of applications; however, they are relatively expensive, require specialized drying equipment, and impose certain requirements on supporting materials.

  Factors to consider when selecting ink:

  When selecting inks for label printing, it is essential to comprehensively consider several factors, including the type of substrate, the printing method and conditions, the customer’s specific requirements, post‑printing finishing processes, the intended application and operating conditions of the label, as well as cost.

  The performance characteristics of label printing inks primarily include hue, fineness, saturation, gloss, adhesion, viscosity, and drying properties; these attributes significantly influence both the printing process and print quality.
