Visual look like in print should be noted that several issues

Visual brush like to see, the following questions deserve our attention: First, the intensity of light directly affects the color of printing proofs to determine the strength of light and dark colors not only affect, but also change the color of the face. Usually, when we observe a column by light, Ying Ming tone light side, the backlight side of the dark tone, a combination of light and dark parts of the middle tone. The same object, in the standard light source is Stern; if the light has been strong, and its color also will change to a bright hue; light enhanced to a certain extent, can be any color to white. Porcelain black and white is the reflection point. Similarly, the waning light of various colors change hue to the low brightness, the light diminished to a certain extent, any color will become black. Like to see the printing press units must meet the requirements of 100LX about the general requirements of illumination to reach in order to correctly identify the color. Second, under the shade under the sun look like and look like there is a difference in actual production, mostly in the power of the irradiation, while the light source are each with a certain color. This gives the right to determine the original color to bring certain difficulties or products, under the concept of color shade, color change is usually the same color lighter, make mere mention of the dark, for example: red light under the concept of color, red lighter, yellowing orange, green changes dark, dark blue, white and red; green under the concept of color, green, shallow, shallow green, yellow green yellow, red and black, white and green; yellow under the concept of color, lighter yellow, magenta changes Red, ■ vine green green,[link widoczny dla zalogowanych], blue, black, white and yellow; blue light under the concept of color, blue, lighter, lighter blue, dark green, yellow black, white and blue. In the print shop, generally choose a higher color temperature (3500 ~ 4100K), Fluorescent color factor as well look like light source, but note that a bit more blue-violet lamp. Third, look at the proofs and prints look look look at the printing proof. The result will be slightly different; twice to see a color when you feel will be different. This phenomenon is called color contrast has reaction. Why is there has color contrast reaction? This is because the color makes the color look at the color of nerve fibers excited and immediately look at other colors,[link widoczny dla zalogowanych], other colors and color caused by a sense of nervous excitement soon,[link widoczny dla zalogowanych], and look at the color of the color nerve After the suppression of excited state, then excited slow, causing a negative hue response. This response coupled with a new look at the color hue, the formation of new colors, so after watching the color change. And there are certain rules to change the hue is the color of the complementary color to look at aspects of change. Color of eyes watching the first followed the change of color tend to look as follows: red, yellow, green, blue, purple, white; red, red earth, green taste of yellow, bright green, green, blue, micro-Chui; yellow, purple taste red, gray and yellow, green, fresh blue, violet, slightly purple; green, red, orange, gray, purple, red violet, magenta; blue, orange, yellow, green, gray-blue,[link widoczny dla zalogowanych], red violet, pale orange ; purple, orange, lemon yellow, green, blue, gray and purple, green and yellow. Understanding of these three aspects and to understand their variation, we like to see in real time visual attention should be, so to ensure the stability of the printing and improve product quality.
