Date: Jan 15 2024 From: Star Color
As an environmentally friendly printing material, water-based ink has been widely used in the field of carton printing.However, in the process of carton heat curing printing, water-based ink faces a series of technical bottlenecks.This paper will discuss these bottlenecks and propose possible breakthrough directions.
Technical bottleneck of water-based ink in carton heat-curing printing
Thermal stability: Water-based ink is mainly composed of water and resin, and its thermal stability is poor.At high temperature, it is easy to produce discoloration, crust and other phenomena, which affect the printing quality and product performance.
Viscosity control: The viscosity of water-based ink has a great impact on the printing effect.Too high viscosity may lead to uneven printing, and too low viscosity may lead to poor ink transfer.In the process of hot curing, the difficulty of viscosity control is increased, which affects the printing quality.
Drying speed: The drying speed of water-based ink is relatively slow, especially in high temperature environments, the drying speed will be further reduced.This may lead to adhesion, foaming and other phenomena in the thermal curing process of printed matter.
Adhesion and wear resistance: In the thermal curing printing process of the carton, due to high temperature, the water-based ink may shrink or deform, resulting in problems such as the surface of the printed matter is not smooth and the adhesion decreases.This may affect the appearance and service life of the printed matter.
Breakthrough direction and technology discussion
Research and development of new water-based inks: For the characteristics of heat-curing printing, research and development of new water-based inks with excellent thermal stability, viscosity control and drying properties.By improving the ink formula, the heat resistance, viscosity and adhesion are improved to meet the requirements of carton heat curing printing.
Optimize the thermal curing process: The influence of process parameters such as temperature, time and pressure during the thermal curing process on the water-based ink is deeply studied.By optimizing the process conditions, the problems of discoloration, crusting and adhesion of water-based ink in the heat curing process were reduced.

Environmental protection and sustainable development: Focus on environmental protection and sustainable development in the development of new water-based ink and optimization process.Use renewable resources, reduce energy consumption and reduce waste emissions to promote the process of green printing.
Strengthen industry-university-research cooperation: Through cooperation with universities and research institutions, we jointly carry out technical research and innovation of water-based ink in carton heat-curing printing.With the help of external resources, we will accelerate the breakthrough of technical bottlenecks and industrial upgrading.
Water-based ink is facing a series of technical bottlenecks in carton heat-curing printing, but these problems can be gradually solved by developing new water-based ink, optimizing the heat-curing process, introducing new drying technology, intelligent printing equipment, strengthening quality detection and control, focusing on environmental protection and sustainable development, and strengthening industry-university research cooperation and other breakthrough directions.This will help improve the performance and application effect of water-based ink in carton heat-curing printing, and promote the sustainable development of the industry.
