Background
The printing machine is one of printers and is widely applied to the fields of textile, home decoration, building materials, decoration and the like.
In the fields of home decoration and textile, such as products like curtains, quilts, sheets and the like, the current main printing and dyeing mode is realized by adopting a roll printing mode, and the products with patterns are formed by sticking dye on the roll-printed die patterns and then printing on cloth.
The roll printing mode is relatively backward, the required ink quantity is large, more pollution is generated in the printing and dyeing process, the environment is not protected, in addition, the image units generated in the roll printing mode are small, the repeatability is too high, the product is relatively low, and the competitiveness is difficult to form.
Therefore, the application demand of the printing machine in the field is gradually improved, after the printing machine prints the pattern on the paper, the pattern is transferred to the cloth through a thermal transfer printing mode, and the printing machine has the advantages that the ink quantity demand and waste are small, the transferred pattern unit is relatively larger, the continuously-changed pattern can be transferred theoretically, the printing machine is not limited by equipment, the individuation capacity is greatly improved, and the product is relatively high-end.
However, in the thermal transfer process, the cost of the transfer medium-transfer paper becomes an obstacle limiting the application of the printing machine, in order to pursue profits and promote the competitiveness of the product, the material manufacturer makes the transfer paper thinner and thinner, the cost of the thin paper can be reduced, but the defect of the thin paper is quite obvious, the thin paper is easy to stretch and deform in the printing process, especially when the printing is finished and the ink permeates the paper, tiny wrinkles are easy to occur under the action of a certain tension of the paper, and the wrinkles are almost unavoidable.
The person skilled in the art proposes several directions for this problem, one to improve the performance of the printer nozzle, enabling jet printing to be finer, the second to improve the ink performance, reduce the impact on the paper, the third to improve the paper performance, strengthen the anti-wrinkle ability of the paper, and the fourth to upgrade and reform the printing equipment, reducing the impact of wrinkles to a minimum.
