With increasingly stringent global requirements for food safety and environmental protection, traditional solvent-based inks, containing volatile organic compounds (VOCs) and posing potential migration risks, are no longer sufficient to meet the printing

Driven by increasingly stringent environmental regulations and growing consumer awareness of green practices, traditional solvent-based inks are being rapidly replaced by more sustainable alternatives in flexible packaging printing.

Achieving high-quality printing results with gravity water-based ink on two vastly different materials—clothing and courier bags—requires not only carefully designed ink formulations but also appropriate substrate pretreatment measures.

To achieve stable and efficient curing of flexo UV ink with LED light sources of different power and wavelengths, a single technical approach is insufficient; a three-in-one solution of "broad-spectrum photoinitiation system + dynamic resin network + inte

If some monomers or resins do not react completely, unreacted "acrylic acid" components will remain, forming a pungent, sour odor. This is especially common with domestically produced raw materials.

Pigment dispersion also needs to be optimized. Highly dispersed pigments can reduce particle agglomeration and improve the density of resin coating, thereby reducing the risk of adhesion loss.
