Method of reducing print pattern of bath towel

When two or more patterns (such as dots, lines, etc.) whose spatial periods differ from each other overlap, they interfere with each other to create another pattern of variation cycles, destroying the overall sense of the original pattern. This phenomenon is called moire. Common complaints in the printing industry. Less is involved in fabric printing, but moiré occurs only after the occurrence of four-color spot color screening and photorealism. For bath towel printing, there are several ways to reduce the moire:

Screen dyeing eliminates refraction and reduces the jagged appearance of moiré and contour edges.

The higher the number of meshes, the greater the chance of avoiding the moire phenomenon, such as: The pattern should use a mesh of more than 120 mesh, which can reduce the appearance of moiré.

Stretching the net should not be stretching the net, it is appropriate to use oblique stretch net, the general angle is 20 ° ~ 35 ° as well. The best way to do this is to test the black-and-white document dot and white net frame on the photoreceptor, record the minimum angle at which the moire disappeared, and then stretch the screen at this angle. This method is troublesome but most effective. .

With dot size selection, the minimum dot size should be at least equal to the diameter of the three filaments or the minimum dot size as long as it is larger than one mesh hole, the moire can be greatly reduced.
