Commonly used in the production of air-cushion blankets and ordinary blanket two, when pressed into contact with the plate, due to the surface of the blanket has a certain degree of adsorption, the printing plate surface of a portion of the fountain solution transferred to the blanket surface. Loss of some of the fountain solution on the surface requires timely replenishment. The amount of replenishment will cause problems with balance and imbalance.
2 water roller
The water roller is the main component that directly contacts the printing plate and supplies the fountain solution at the same time. The excessive contact pressure with the printing plate will damage the image part, and the fountain solution cannot uniformly coat the printing plate. ". If the contact pressure is too light, the fountain solution on the surface of the printing plate will not be properly coated, resulting in a similar coating condition, and the “plate†phenomenon will appear on the surface of the printing plate.
3 plate area
The amount of fountain solution required on the surface of the printing plate is directly related to the area of ​​the graphic. The area of ​​the map is large, the area of ​​relative blank is small; the area of ​​the picture is small, and the area of ​​relative blank is large. Under normal circumstances, the printing plate with a large area requires less amount of fountain solution, whereas the amount of fountain solution is more.
4 ink thickness
The ink layer thickness of the print has a certain relationship with the size of the fountain solution on the surface of the printing plate. There are two ways to increase the thickness of the printing ink layer. First, the volume of the fountain solution is constant and the amount of ink is increased. First, the amount of ink is constant and the amount of fountain solution is reduced. The reason for these two approaches is the same. They both increase the ink content under "oil-in-water" conditions and reduce the content of fine water droplets in the ink on the plate surface, thereby achieving the purpose of increasing the ink layer thickness.
Carton
packaging is to promote the beautification of goods and improve the
competitiveness of the products with its beautiful shape and decoration. Since
the shape and structural design of the carton are often determined by
the shape characteristics of the packaged goods, there are many types, such as rectangular, square, polygonal, shaped carton,
cylindrical, etc., but the manufacturing process is basically The same, that is, the selection of materials - design icons - manufacturing templates - stamping - joined into boxes.
The
raw materials are coated paper, special paper, powdered ash, kraft
paper, corrugated paper, which are used to hold items and can be
recycled.
Paper product packaging is the most widely used type in packaging industrial products. Carton
is the most important form of transport packaging, and carton is widely
used as a sales package for various products such as food, medicine,
and electronics. With
the change of transportation mode and the change of sales methods, the
styles of carton and carton are becoming more and more diversified.
Almost every new type of non-standard carton is accompanied by a set of
automatic equipment, and the carton itself is also becoming novel. With
the means of merchandising promotion, we believe that the future carton
packaging will develop in the direction of environmental protection
economy, and there will be a new form to show us.
