The effect of this color value is necessarily gray and black, and in many cases, the picture is still There will be light gray bars in the black part, which affects the overall effect. Some designers use C100, M100, Y100, and K100. The effect of inkjet or photo printing is too thick, not easy to dry out, and the picture is easy to bloom.

Be careful not to use the RGB mode. Of course, the printer will generally convert it when printing, but the colors may have some origins.
