Nowadays, electronic reading materials are all the rage, far away from the traditional printing, but electronic packaging is impossible, and virtual packaging is not considered. The development of various new technologies will not affect the development of carton printing, but will also greatly promote the development of carton printing. In this sense, Jinan packaging printing is a printing industry that will never decline.
Here are some common carton printing methods:
Offset printing is mainly used for printing paper materials. The size of the sheet fed offset press can be changed for greater flexibility. At present, most web offset presses have fixed printing sizes. Its application is limited. With the development of science and technology, web offset press is also improving. Now we have developed a rotary offset press which can change the printing format.
At the same time, a seamless web offset press is developed. The drum of the web offset press is seamless, just like the web gravure press. The offset press is also improving its printing function. Corrugated board can be printed after improvement and adding some parts. After the improvement and installation of UV drying device, UV printing part can be printed out. These improvements continue to expand the use of offset presses in the field of packaging and printing. Offset water-based ink is about to enter the practical application stage. Offset printing is another step.
The main advantages of flexographic printing are:
1. The equipment is simple in structure and easy to form a production line. In offset, gravure and flexo printing equipment, flexo printing machine structure is the simplest. Therefore, the price of flexographic press is relatively low, and printing enterprises invest less in equipment. At the same time, because the equipment is simple, easy to operate and maintain. At present, the vast majority of flexo printing machines, such as grinding, polishing, cutting, die-cutting, indentation, drilling, windowing and other processing lines, forming a production line. Labor productivity has been greatly improved.
2. Extensive applications and substrates. Flexographic printing can print almost all printed matter and use all substrates. Especially in packaging printing, corrugated printing is unique.
Water based inks are widely used. In offset, gravure and flexographic printing, only flexographic ink is widely used. It is non-toxic, pollution-free, environmentally friendly, especially suitable for packaging and printing.
Low cost. The low cost of flexography has been widely recognized abroad.
Gravure printing, full of three-dimensional ink, a variety of printing methods, good printing quality. Stable printing quality. Printed board life. Suitable for mass printing. Gravure printing can be used to print extremely thin materials, such as plastic films. However, the gravure printing process is complex, high cost, its benzene ink pollution environment. These two problems affect the development of gravure printing. Especially with the decrease of the number of printing parts, short printing needs a large number of low-cost printing parts, which makes the gravure printing lost its market.
