1. Hue
Hue is the most basic feature of color. People call colors such as red, yellow, and green according to hue. Hue is determined by the color of light reflected from the surface of the object to the optic nerve of the human eye. The monochromatic light can be determined by the wavelength of its light. If the color of the light composition is mixed, the hue is determined by the ratio of the light amounts of the various wavelengths of the mixed light. For example, in sunlight, the printed surface reflects colored light having a wavelength of 500 to 550 nm, while the light that absorbs other wavelengths is visually green.
The hue can be represented by the shape of the spectral reflectance curve. The curve A indicates that the hue of the object is green, and the curve B indicates that the hue of the object is greenish blue.
2. brightness
Photometrically describes the brightness of a color as the value of light (ie, the energy of light). Can be measured with a photometer. It is generally believed that the reflectance of the surface of a color object is high, and their brightness is large. The hue of the two colors A and B is the same, but the brightness of the color A is larger than that of B, and thus the colors A and B are different visually. .
3. saturation
Saturation (also called chroma) refers to the purity of the colors. The various colors of light visible are the most saturated colors. The more the white light component incorporated by the spectral color, the less saturated.
The saturation of the object's color depends on the selectivity of the reflected spectrum of the surface of the object. The object has a high reflectivity in a narrow band of the spectrum, and the reflectivity of other wavelengths is low or no reflection. The saturation of this color is high.
1. The juxtaposition of outlets
The bright spot of color prints has relatively small dot coverage in the corresponding parts of the yellow, magenta, cyan, and black plates and the bright highlights of the manuscript. Dots are sparsely distributed, and the dots of the bright spot of prints are mostly in parallel.
When the yellow dot and the magenta dot are juxtaposed, white light shines on the yellow dot. The yellow dot absorbs blue light and reflects red light and green light. White light shines on the magenta dot. The magenta dot absorbs green light and reflects red light. Blu-ray. The four shades of light are mixed in space. According to the additive color method, red light, green light, and blue light are mixed into white light, and the rest is red light. If the distance between two outlets is small, they are very close to each other and the human eye sees red. In the same way, magenta and blue dot are tied to the human eye to see blue, green dots and yellow dots are tied to the human eye to see green.
When the two outlets are juxtaposed, the resulting color is shifted to one side of a large outlet, such as a large blue dot and a small red dot, and the resulting color is partially cyan.
When the three dots of yellow, magenta, and cyan are juxtaposed, the ink absorbs part of the color light, and the paper absorbs different shades of light. The reflected light is not 100%. When the distance between dots is small, the human eye sees gray.
2. Overlapping of dots
In the dark tone portion of color prints, the dot ratios of the corresponding portions of the yellow, magenta, cyan, and black plates and the original dark tone are relatively large, and the dots are dense, so that the dots of the dark tone portion of the print are mostly in an overlapped state.
When the magenta dots are superimposed on the yellow dots, the white light first shines on the magenta dots, the green light in the white light is absorbed, the red light and blue light are transmitted to the yellow dot, the blue light is absorbed by the yellow dots, and the magenta is transmitted through the magenta dots. The dots were shining white, and only red light was reflected from the surface of the paper. The red eyes were seen by the human eye. By the same token, Lu Hong and the Qinghai dot overlap to see what the human eye sees is blue, and the blue dot and yellow dot overlap to see the green color. When the yellow, magenta, and blue three-color dots overlap, the blue, green, and red light in the white light are absorbed, and the human eye sees black color.
The manner in which the dots overlap and reproduce the colors is affected by the transparency of the ink. The ink with low transparency has no color rendering effect, and the completely opaque ink can only be printed as the first color.
The middle part of the printed matter is rich in layers, and the way of color synthesis is that the dots are juxtaposed and the dot overlaps.
According to the principle that the dots are juxtaposed and the dots overlap, the amount of light absorbed by the ink, the thickness of the ink layer, the color density of the ink, and the order of printing will all affect the effect of color reproduction.
