Dot number
The number of screen lines determines the fineness of the image, similar to the resolution. The common line number is applied as follows:
Line 10-120: Prints of low quality, long-distance prints such as posters and posters are generally printed using newsprint paper or offset paper, and sub-powder paper and coated paper are sometimes used.
150 lines: Normal four-color printing generally use this accuracy, all types of paper have.
Line 175-200: exquisite albums, pictorials, etc., mostly printed on coated paper

FM network point
The screen adjustment network point is a newly developed screening method since the 1990s. Its difference from the amplitude modulation network point is that the size of the network screen point of the screen adjustment network is fixed, and it is achieved by controlling the denseness of network points. The dots in the highlights are sparse, and the dots in the shadow tone are dense.
