What Challenges Exist in Adhesion and Drying When Using Water-Based Pre-Printed Ink?

The global printing industry is currently undergoing a significant transformation, driven by stringent environmental regulations and a growing demand for sustainable manufacturing practices.

How can we prevent sedimentation and stratification of corrugated cardboard ink during storage?

The sedimentation and stratification of corrugated cardboard ink during storage are mainly due to density differences or insufficient dispersibility of pigments, binders, and additives in the ink.

What durability improvements does the superior adhesion of corrugated cardboard ink bring?

Corrugated cardboard ink, as a crucial element in giving corrugated cardboard its beautiful appearance and displaying key information, significantly improves the durability of corrugated cardboard packaging due to its excellent adhesion.

What are the methods for controlling the penetration of corrugated cardboard ink on multi-layered corrugated surfaces, and what are their effects?

Water-based inks are the mainstream choice for corrugated cardboard printing. Their binders are usually formed by resin and water in the presence of surfactants to create an oil-water miscible system.

How can the insufficient water resistance of water-based pre-printed ink be improved through formula adjustments?

For demanding applications, chemical crosslinking and physical protection can be combined. For example, crosslinking agents can be used to enhance the cohesion of the film layer, and then water-based varnishes can be used to enhance the surface hydrophobi

How to optimize the drying speed of corrugated cardboard ink during high-speed printing to avoid paper deformation and ink smudging?

If the ink in the ink fountain does not circulate sufficiently for a long period of time, it can easily lead to uneven solvent evaporation, increased viscosity in some areas, affecting the uniformity of the transfer and causing drying differences.
