Basic knowledge of printing network--network point of view

In dot-screen printing, the choice of dot angles plays a crucial role. Choosing the wrong dot angle will cause interference fringes.

The common dot angles are 90 degrees, 15 degrees, 45 degrees, and 75 degrees. The 45-degree network has the best performance, is stable and does not appear dull; the 15 degree and 75 degree angle stability is worse, but the visual effect is not rigid; the 90 degree angle is the most stable, but the visual effect is too rigid There is no beauty.

If two or more types of dots are put together, there will be mutual interference. When the interference is serious enough to affect the appearance of the image, the so-called “rhizard pattern” appears.

In general, when the angle difference between the two types of dots is 30 degrees and 60 degrees, the overall interference fringe is still more beautiful; the dot angle difference of 45 degrees is next; when the angle difference between the two dots is 15 degrees and 75 degrees When the interference fringes can damage the image.

The picture is as follows:
