Analysis of the Effect on the Printing Resistance of Baking Plates from Printing

From the printing aspect, there are mainly three factors: printing plates, technical personnel, and offset printing machines.

1. Plates

The same is used for baked plates (in the case of the text version). In the face of different types of offset presses, the resistance to print will be different. If the machine is 08, the resistance of the unbaked plate will not be lower than about 60,000 impressions. If it is the same type of plate that has been baked, its resistance force will not be baked 2 - 3 times; and 01 machine, the non-baked printing plate of its resistance to force in the 2-30000 India, after baking, the printing plate of the India Force between 3 - 50,000 printing. From this we can see that the difference between the same type of printing plate is so great that the difference between different types of printing plate will be even greater.

Plates are generally divided into two types of textures and text plates. Their resistance to printing is also very different. In addition, human factors can also affect the printing force of the same printing plate, such as: the quality of the printing plate, the operator of the offset printing press, etc.

2. Technical staff quality

For the technical staff who study offset printing or plate making, due to their own understanding, different lengths of practice, and their different learning methods, the basic qualities of the operators are different, which also results in subtle differences in their work quality. .

3. Offset printing machine

Different offset presses vary in their respective pressure adjustments and use times are different. The degree of wear on the same type of printing plate is different, which is a factor of the machine itself. The same machine faced different types of printing plates and different operators, and the printing plate's resistance to printing force was also different. As for the 08 machine, in the printing of advertising, lines and the like of the printing plate, due to the layout of the solidified layer, the unit area is larger, its resistance to India will accordingly increase. In addition, with the offset press of type 02, for example, the offset resistance of the upper and lower printing plates is different. The pressure of the two rollers is difficult to adjust uniformly. This is also a common problem in the printing industry. Now.
