Since the dot change occurs in the surrounding area of ​​the printing dot, the more dots per unit area, the more the surrounding dots of the dot, and the greater the amount of change in the dot, which shows that the dots of the thin cable are enlarged.

Printed outlets may be divided into coarse or fine outlets depending on their use. Fine print products for close-range viewing should use fine dots, such as periodicals, prints, trademarks, and packaging for printing products. Printed products viewed from a distance must use coarse dots, such as large posters and posters, in general. Dots are in inches, which is how many lines (horizontal and vertical lines) are within one inch of area. Common network lines are 60 l/in, 90 l/in, 133 l/in, 150 l/in, and 175 l/in.
