Net color concept and its printability

Send a spot color, and then discuss some of the shallow network with everyone, hoping to provide some help for everyone, but also learn from each other!

Shallow net refers to a certain kind of base color plus Internet mesh screen, and the generated color will exist as a percentage of the base color. This is actually a method of defining a color that is similar to the basic color and different shades.
The following printability needs to be taken into account when using light mesh colors:

(1) Avoid using shallow light mesh colors. A light mesh color of less than 2% of a certain primary color is difficult to print even if it can be expressed on a document or an image-setter output film.

(2) Avoid tiny shallow web changes. There is almost no printing machine that can reproduce the difference of 1% light net, and the 5% or so change is the actual technical limit, which is why the incremental amount in the shallow setting menu is 5%.

(3) Avoid using light mesh colors on thin lines. Because the thin lines that have been added to the net have a floating feel, much like dirty spots and misprints, it is best to use solid colors when designing thin lines for printing.

(4) Light grid color accumulation calculation. If you use a 50% light mesh color of a basic color when designing a pattern, and then perform 60% light mesh processing on the entire pattern, the light mesh color of the primary color is subtracted twice to become the primary color. 30% light net color, multiplied by two overlapping times.

(5) spot color shallow network and primary color shallow network. Spot colors use solid colors to define colors. If a certain percentage of light colors are used, the color tone will not change, but only saturation. Its four-color percentage for a certain primary color is specific. If a shallow mesh is used for the primary color, all percentages of the four colors contained are scaled by the same amount. The hue of different saturation colors of a certain primary color is the same, but their four-color percentage is not a linear relationship of equal scaling, but changes according to the proportional relationship of the neutral gray balance of the ink mixture.
