Thermal transfer process printing method is divided into two major parts: transfer film printing and transfer processing, transfer film printing using dot printing (resolution up to 300 dpi), the pattern pre-printed on the surface of the film, the printed pattern layers are rich, bright colors, varied, small color difference, good reproducibility, can achieve the effect of the design pattern requirements, and suitable for mass production; transfer processing through the thermal transfer machine a processing ( Heating and pressure) will be transferred on the film of the transfer of exquisite patterns in the product surface, forming the ink layer and the product surface into one, realistic and beautiful, greatly improving the grade of the product.

For many years, book pages have been an important part of the paper industry. Nowadays, the continuous increase in the production capacity of book pages has become a reality through new technologies that can satisfy product quality. The development of multi-layer headboxes provides opportunities for the simultaneous use of different primary fibers and secondary fibers in the production of book pages, making the final product versatile. In a multi-layer headbox, two types of ingredients or three fibers are typically combined to form a single paper layer.
In addition to the use of a multi-layer headbox, the concentration-diluted distribution technique can reduce the quantitative change of the sheet. This technique can be easily retrofitted to existing paper machines. Especially for multi-layer headboxes, the use of concentration-diluted distribution techniques can reduce quantitative distribution changes from 2.0 to 2.5% to 1%. Reduce fluctuations in the amount of paper, copy out the uniform paper.
Mr. Lao Jiaxuan of Northwestern Institute of Light Industry introduced some of the current developments in providing world paper book production technology. The summary is as follows:
