The quality index of silica gel ink screen 

Printed matter can see in our daily life and work in a large part of silica gel ink prints, of course, with much, there will inevitably be unqualified, after all, what birds are some reasons for this. So what is the unqualified? What are the important indexes to measure the quality of silica gel ink screen? Let's take a look at it: 

An important indicator of gel ink screen quality is dot, it is printed matter can reflect the level of different layout, color gradient shading (Ming An) basic unit of natural boundary. It plays a role in printing to determine print colors, levels and image contours. Therefore, when printing, only the dot size is accurate, in order to faithfully reproduce the original color, to ensure that the printing process to achieve better results. 

As a result of silicone ink printing products, the intensity of the page is through the size of the dot to show, the size of different sites, commonly known as "Cheng."". Only by accurately understanding the concept of dot number can we better use dot print to print the closest color of the original. Therefore, the understanding of the number of outlets is the printing operator and quality inspection personnel should master the knowledge. I would like to sum up several outlets as follows: 

The number of points within 5 or less points is identified by the number of particles that can hold the same black dot between the two black spaces. The gap between the two black dot on the edge of the inside, can be placed three of the same size as the black dot, dot is 1; if the two outlets within the distance, can accommodate two equally large outlets, called 2 outlets and so on. And the identification of 5 or more points is measured by the number of white dots that can hold between the two white spots. 

The above situation shows that the so-called number of outlets, that is, in the unit area of the percentage. For example, 1 points are 10%, others are 100%. A few more dot product suites ink printing more thick, shallow and vice versa. 

The size of the dot area determines the level of the page. Usually, the layers on the screen are divided into three levels, that is, the high key layer is composed of 1 to 3 dots, forming bright spots on the picture. The middle gradation shows the transition area of the screen, usually between 4 and 6 dots. The dense screen composed of 7 to 9 dots is a low key layer. The brightest part of the printed page, i.e., the highlight portion is 1 points below.
