The performance of water-based ink printing.

Published by Jaker Chen April 09,2022

What are the main ingredients of water-based inks?

The water-based ink is composed of water-based acrylic resin, color paste, water and additives, and displays the pattern and text on the packaging product through printing. The quality of the ink affects the composite fastness of the composite packaging.

The main components of water-based ink are as follows:

1. The main component of the pigment
Colorants include pigments and dyes, which are colored substances with extremely fine particles. Pigments are generally insoluble in water or in the binder, while dyes are generally soluble in the binder. The pigment has a great influence on the ink. Its color determines the hue of the ink, and the amount used determines the concentration, which can affect the drying of the ink to a certain extent. The pigment can make the ink have a certain viscosity and dryness. Moreover, the durability of the ink in all aspects is also determined by the pigment.
2. The main component of the binder
The binder can be said to be the heart of the water-based ink, and its role is multi-faceted, a fluid with a certain viscosity and viscosity. The binder has a certain fluidity, and forms a uniform thin layer after the ink is printed. After drying, a film with a certain strength is formed, which protects the pigment and enables the pigment to adhere to the printed product. The binder to a large extent determines the viscosity, viscosity, yield value and fluidity of the water-based ink. The binder has a great influence on the fixing speed, drying speed, drying type and printing effect of the ink. Therefore, high-quality water-based ink determines the high-quality binder, and its quality determines the key factor of water-based ink printing.
