What is Continuous Convergence Mesh Tuning?

Continuous tone means that the image of a picture is composed of very delicate dyes or pigment particles mixed in different proportions, and the color is in a continuous gradual state. For different compositions, the continuous tone of the artwork is composed of different particle density within the unit area.

The term "mesh tones" refers to the fact that the color change and depth change in printing are essentially discontinuous, and the change in color and tone is represented by the juxtaposition, superimposition, or half-and-half overlap of dots of different sizes. Since the pitch of the dots is smaller than the visual resolution of the human eye, the human eye will regard the halftone image composed of the colored mesh as a continuous layer change and color change, but if observed with a magnifying glass, only one particle can be seen. Dots of different sizes and colors can't see continuous changes in color and gradation, such as negatives used in printing and offset printing.
