Solution to bubbles in water-based solid acrylic resin ink

1. Dust and oil stains adhere to the surface of the substrate. 2. During printing, the ink itself may have bubbles or uneven viscosity. 3. Printing speed is too fast or uneven.

What are the printing consequences of excessive separation of water-based acrylic resin oil ink?

The quality of offset printing products is inseparable from whether ink and water maintain a certain balance. During the printing process, excessive or insufficient water supply is often prone to occur, as the amount of moisture in the printing plate is reflected in the dirtiness of the plate. However, the so-called dirtiness is not only caused by a small amount of water, operators often mistakenly increase the water supply, causing the ink and water to lose balance, forming a vicious cycle.

What are the commonly used solvents for acrylic resin?

Solvent is an important component of acrylic resin. Good solvents can make the resin clear and transparent, reduce viscosity, and improve the film-forming performance of the resin and its coatings. According to the principle of similar solubility, toluene, xylene, alcohols, esters, ketones, etc. are commonly used solvents. When choosing, the cost, volatilization rate, toxicity, and other factors of the solvent should be considered.
