Carton gravure ink: Differences between high and low viscosity
Date: Dec 11 2023 From: Star Color
Water-based ink, as an environmentally friendly, non-toxic printing material, is widely used in the field of packaging printing.Among them,
Carton gravure ink, with its unique characteristics and excellent performance, has gradually become the mainstream ink for carton, paper bag and other packaging printing.In the process of production and use, the viscosity of water-based ink is an important parameter, which directly affects the printing effect and production efficiency.This article will give you a detailed overview of the differences between high and low viscosity Carton gravure ink to help you better understand this environmentally friendly printing material.
Carton gravure ink is a water-based ink that uses water as a solvent and is mainly composed of pigments, resins, additives and water.It has the advantages of environmental protection, non-toxic, non-combustion, in line with the green development trend of the modern printing industry.In the production and use of Carton gravure ink, viscosity is an important physical quantity, which reflects the strength of liquid flow.There are obvious differences between high viscosity inks and low viscosity inks in printing effect and production efficiency.
High viscosity and low viscosity characteristics
1.High viscosity ink features
High viscosity ink refers to water-based ink with high viscosity, which has the following characteristics:
Good printing effect: The fluidity of high-viscosity ink is poor, and the thickness and uniformity of the ink layer can be better controlled during the printing process, so as to obtain a clearer and fuller printing effect.
Good water resistance: Due to the high content of resins and pigments in the high viscosity ink, its water resistance is good, and it can meet the needs of some special prints.
Good storage stability: high viscosity ink viscosity is high, can maintain good stability in the storage process, not easy to stratification, precipitation and other phenomena.
2.Low viscosity ink features
Low viscosity ink refers to water-based ink with low viscosity, which has the following characteristics:
Good fluidity: The fluidity of low-viscosity inks is better and can better penetrate into the paper fibers, thereby obtaining a smoother and more uniform printing effect.
Fast drying speed: Due to the low content of resin and pigment in the low viscosity ink, the drying speed is faster, which can improve the printing efficiency.
Wide range of application: low viscosity ink is suitable for a variety of different types of paper and printing press, with strong adaptability.
3.Selection and use of high viscosity and low viscosity
In the production process, Carton gravure ink with high or low viscosity should be selected according to the requirements of the printed matter, the type of printing press, and production efficiency.
Print requirement
For some prints that require high definition and high gloss, such as high-end packaging boxes, albums, etc., high viscosity inks should be selected.For some prints that require rapid drying and low cost, such as ordinary cartons, labels, etc., you can choose low-viscosity inks.
Type of printing press
For some high-speed printing presses, such as rotary printing presses, multi-color printing presses, etc., low viscosity inks should be selected to improve printing efficiency.For some flatbed printers that require fine printing, you can choose high-viscosity inks to ensure the printing effect.
Production efficiency requirements
In terms of production efficiency, low viscosity inks have greater advantages.Due to its good fluidity and fast drying speed, it can greatly improve the printing speed and production efficiency.Therefore, in the case of fast printing on the production line, it is more appropriate to choose low-viscosity inks.However, high-viscosity inks have certain advantages in printing quality and storage stability, and are suitable for some special prints and fine printing requirements.In the specific selection, should be considered according to the actual production situation.
Carton gravure ink with high viscosity and low viscosity have their own characteristics and ranges of use.In the process of production and use, the appropriate viscosity should be selected according to the requirements of the print, the type of printing press and production efficiency.For prints that require high definition and high gloss or flatbed presses that require fine printing, you can choose high viscosity inks;For fast drying, low-cost prints or high-speed printing presses, you can choose low-viscosity inks.In practical applications, it is also necessary to select and adjust according to specific production conditions.
