Preparation method of anti-deformation water transfer printing film

Abstract

The invention relates to the field of water transfer printing films, in particular to an anti-deformation water transfer printing film preparation method which comprises the following steps: S10, equally dividing an original pattern into N strip patterns which are arranged in sequence in the transverse direction or the longitudinal direction; the same side of the S20N long-strip patterns is a connecting side, and the two ends of the connecting side of the long-strip patterns are sequentially connected to form a middle pattern; s30, a fan-shaped blank is formed between every two adjacent strip patterns, and the two sides of each fan-shaped blank are stretching sides; a plurality of compression rings of which the circle centers coincide with one another are arranged on the circumferential side of the S40 inner ring; and S50, the compression ring on the outermost side and the outer ring form a first compression area, a second compression area is formed between the compressed first compression area and the compression ring on the secondary outer side, and so on until the compression ring on the innermost side and the first compression area correspond to the part with the larger stretching degree in the transfer printing process, so that the water transfer printing effect is guaranteed.

Description

technical field [0001] The invention relates to the field of water transfer printing films, in particular to a method for preparing an anti-deformation water transfer printing film. Background technique [0002] At present, in the process of water transfer printing of cylindrical products, there are mainly two launching methods. Under the condition of ensuring that the pattern is not deformed, the rolling method is used for transfer printing, but the starting position and end position of the pattern will inevitably change. The appearance of coincidence lines will affect the appearance; moreover, the way of vertical water entry is adopted to avoid the appearance of coincidence lines. However, during the transfer process, the pattern is stretched in the vertical direction and squeezed in the horizontal direction. As the depth increases, the degree of pattern stretching and extrusion also increases at the same time, the pattern is seriously deformed, and the effect of water tra...
