twenty three. What is color light additive method?
Mixture of two or more color lights to obtain a new color light is a color light addition method. The new color light is brighter than any of the color lights involved in the mixing, and the color light addition method follows the principle of increasing lightness. After the three primary colors of light are mixed in different proportions by the color light additive method, all the natural light colors can be produced.
twenty four. What is the three primary colors?
Pigment refers to a material that has a certain color and can color other objects. The colorant is a non-luminous body, the color of which depends mainly on its absorption and reflection of light from the outside. The three primary colors of pigments are: yellow, magenta, and cyan, which are complementary colors of the three primary colors of blue, green, and red, respectively. The yellow colorant can absorb blue light in white light, transmit or reflect red light and green light in white light; magenta color material can absorb green light in white light, transmit or reflect red light blue light in white light; cyan color material can absorb white light The red light transmits or reflects light and green light in white light.
25. What is color subtractive?
The color subtractive method refers to the phenomenon that two or more kinds of color materials are mixed to obtain a new color. Based on the three primary color materials, according to the different proportions, all other colors can be prepared, and the three primary color materials cannot be mixed and prepared with other color materials. The essence of the color subtractive method is to increase the number of times that the color material is selectively absorbed, so that the color light energy is weakened, and then the brightness is reduced and the color is dark when the color changes.
26. What are the ways in which subtractive mixing of pigments is mainly divided into several ways?
The subtractive mixing of pigments is mainly divided into two types: one is the reconstitution of pigments, and the other is the superposition of pigment layers.
27. What is the harmonization of pigments?
The blending of colorants refers to the method of mixing two or more colorants uniformly to obtain the desired color color according to the requirements of the color, and is abbreviated as color toning. With yellow ink and magenta ink mixed color as the column, when the yellow ink alone color, the yellow pigment will subtract the blue light in white light, reflect the red and green light, the mixture of the two is yellow; when the magenta alone When in color, the magenta pigment in the magenta ink subtracts the green light in the white light, reflects the red light and the blue light, and the mixed two colors of light reflect the magenta; when the two inks are mixed, the yellow pigment decreases To the blue light in white light, the magenta pigment subtracts the green light in the white light. As a result, only the red light is reflected, so we see that the result of the blending of the yellow ink and the magenta ink is the red ink.
28. What is the overlap of pigments?
The superposition of the colorant layer means that the two or more layers of the colorant having transparency are overlapped together to present a color rendering method of a new color. Such as two layers of transparent ink overprint. For example, if the blue ink is overprinted on the yellow ink layer, the incident white light will subtract the red light from the upper blue ink, and the green light and blue light passing through the blue ink layer will be subtracted from the yellow ink layer when it reaches the yellow ink layer. Only the green light reaches the white paper through the yellow ink layer and is reflected by the white paper, so we see that the green ink is overprinted on the yellow ink layer and the result is green.
29. What are the basic ways to organize colors in outlets?
After different proportions of dots with more than two colors are overprinted, due to the size of the dots and the angle of screening, the dots of different colors sometimes overlap and sometimes appear side by side. Generally, where there is a large percentage of outlets, there is a greater chance of network overlap and less opportunity for juxtaposition; where the percentage of outlets is small, there is a greater chance of collocation of outlets and a smaller chance of consolidation. Some outlets will also be in a semi-overlapping semi-parallel state, but in general, there are only two basic modes, namely, overlapping dots and dots.
30. What is the mechanism of overlapping coloration?
The dot overlap color is the stacking of color materials in different color dots. It follows the subtractive color mixing principle, which requires high transparency of the ink, lower brightness of the new color, and higher chroma.
31. What is the mechanism for juxtaposition of dots?
When the dots of two different colors are juxtaposed, because the dots are so small that the human eye can not distinguish the light components that they reflect, it is the light that they see after the colored light reflected by them is added to the space. Taking yellow and magenta nets as an example, yellow dots absorb blue light and reflect red light and green light; magenta dots absorb green light, reflect red light and stroke, and when the human eye cannot distinguish the dots It gives the feeling that red light + green light + red light + blue light = (red light + green light + blue light) + red light = white light + red light.
