1) The dot scale of the basic color is 65% - 90%. Because more than 80%
of the dots increase, the layers are easy to merge. Therefore, for this area,
we need the basic color of the layer. We should keep the layer under the
premise of emphasizing the enough field density, not emphasizing the field
density saturation, which results in the level parallel of the basic color.
Processing Essentials: the depth of the basic color of the required level, with
the emphasis on more than 80% of the area's color amount to be moderately
reduced, so that it is far away from the field color block, so that printing
can not only print enough field density, but also maintain the level.
2) In book printing color
processing, it is difficult to balance the bright saturation of color and the
light and shade level in color. If you want to preserve the light and shade
level in color, you need to use complementary color. Shenzhen packaging
printing uses complementary color, the brightness of color will be reduced, and
the gray level will be increased. If you want to make the color bright, you
need to put less complementary colors, so that the light and shade levels in
the color will be affected. For timeliness and packaging products, we should
emphasize the saturation of bright colors, which will affect the light and
shade levels of some colors. In this way, the final print image has a strong
sense of color and good visual effect. The key lies in mastering a
"degree", which is the expression of the operator's aesthetic level
and directly related to the effect of color art.
3) The layer texture in the basic color of depth is mainly represented
by the main color version, such as warm colors such as red and orange: it is
represented by the Y and M color versions; cold colors such as green and cyan
are represented by the C color version. Therefore, it is necessary to emphasize
the layer texture of the main color plate, so as to vividly show the
characteristics of the physical layer.
4) the basic color of the middle adjustment area is adequate. The
range of tone adjustment in middle adjustment area is 35% 1 65%, which is the
main part of most objects and the key area of color processing. To adjust the
basic color of this area to the best saturation, the key is to increase the
color by 5% or more. For example, safflower, the M color in the bright medium
is 40%, which can deepen the treatment to 45% and make the red more saturated
and bright.
