Matters needing attention in printing of thermal transfer paper

Lithographic offset printing uses the principle that oil and water are incompatible with each other for printing. Therefore, the paper generally stretches after printing, while shrinkage becomes less common. In order to eliminate this type of failure, the relevant printing process is now discussed.

Paper is a material containing variable plant fiber tissue. It has the function of absorbing moisture and releasing moisture. When the moisture in the air is constantly changing, it will adjust and balance with the air humidity. When the air humidity is higher than the moisture content of the paper, it will absorb the moisture in the air and expand and expand; otherwise, it will release moisture and shrink and shorten to achieve a relative balance with the environmental humidity.
