There are marks and pictures on the carton. How are they printed? In addition to ink, carton printing machine also needs auxiliary raw material ink (ink).
So what are the raw materials used in water-based printing press? Now, we (carton machinery) have a brief understanding of the following:
1. Pigment ink is to provide color and color concentration, can not be directly attached to the paper;
2. In order to control the function of water-based ink, resin can affect the adaptability of water-based ink to printed matter and directly affect the quality of printed matter;
3. Additives are for the convenience of application, and have special requirements for the characteristics of ink, such as anti friction, inhibition of foaming, color stacking, etc;
4, water is used to dilute the water-based ink, now most of the water-based ink do not contain alcohol, can only rely on water to reach the viscosity of the machine. (pay attention not to add water directly in the production process)

How often does the mechanical cleanliness of the carton need to be checked?
It is true that in the process of repairing carton machines, we must pay attention to their practicability and do a good job in the accurate protection and maintenance of funds, but it can also effectively improve productivity, and carton machines also have various key points, but we can't ignore them. It requires lubricating some equipment to check the carton machine in real time every day. If you want to lubricate these carton machines, you can clean them anytime and anywhere, and others have
Zhongshan carton printing machinery slotting roller unreasonable how to solve?
In the paperboard line the use of convex concave more. Because of the influence of paper and production environment, the thickness of paperboard is different, and the structure of roller is also different. The main parameter is that the width of the upper and lower roller should be appropriate, and the step transition arc of the roller should be adjusted according to the depth of the pressing line and the depth of the applicable paperboard. Generally speaking, the thicker the paperboard, the wid
Carton brush machine: what is the ink material of water-based printing press?

Influence of Zhongshan carton printing machine on compressive strength
With the development of printing technology in recent years, some enterprises think that the impact of printing on the compressive strength of cartons is getting smaller and smaller, even negligible. In this regard, the inspection and quarantine part of the special corrugated box before and after printing compressive strength of the comparative sampling test. A group of prepress and Postpress carton samples were randomly selected from 9 export corrugated carton enterprises, totally 9 groups. Eac
