Background technique

AM dots are the most widely used dots. Its dot density is fixed, and the color depth is expressed by adjusting the size of the dots, thereby realizing the transition of tones. The size of the dot is determined by the coverage of the dot, also known as the ink penetration rate. Generally speaking, I like to use "success" as the unit of measurement. For example, the outlets with 10% coverage are called "10% outlets", and the outlets with 20% coverage are called "20% outlets". In addition, the outlets with 0% coverage are called It is the "absolute network", and the sites with 100% coverage are called "fields". The tone of printed matter is generally divided into three levels: bright tone, mid tone, and dark tone. The dot coverage of the bright part is about 10% to 30%; the dot coverage of the middle tone is about 40% to 60%; the dark part is 70% to 90%.
