Color difference and visual feeling of the hottest

The color difference and visual feeling of posters after glazing

high work efficiency

first, the color difference after glazing

the most commonly used glazing methods of posters are PP mounting glazing and UV glazing, and now we will analyze their color differences with non glazing, PP fog glazing and UV glazing

after polishing, it has a great impact on the tone reproduction of printed matter. Its common point is to increase the concentration domain of bright and intermediate tones and compress the concentration domain of dark parts. According to sun Yizhi's "Research on the color difference of Jinan assays due to the large number of customers before and after the polishing of printing materials", it can be found that:

type of polishing

UV polishing

PP fog surface polishing

various effects

full page printing ink concentration

is greater than that without polishing

less than unglazed

the reproduction concentration field of the printing plate

the yellow version is smaller than that of the unglazed version, and the cyan, magenta and black versions are larger than that of the unglazed version, but the reproduction concentration has not been significantly changed

are smaller than those without glazing, but the range of change is large

dot enlargement

no matter what color version, it is larger than unglazed from 10% to 90%

80%~90% of the points intersect with the unglazed point expansion curve less than the unglazed point

color difference

is not much different from that without glazing

it's more glossy than the producers of uninsulated materials


is not much different from that without glazing

is bigger than unsightly

the effectiveness

is not much different from that without glazing

smaller than unpainted

ink expressiveness

tends to increase

tends to weaken

color difference

has a large response to the color difference of the color block of the point

the color difference reaction of the color block of the point is small

printing contrast value

the printing contrast value of the horizontal plane is smaller than that of the unglazed printing contrast value

the printing contrast value of flat is smaller than that of unglazed printing

gray balance curve

regardless of the color, the curve is located on the gray balance curve without glazing

the gray balance curve of the bright part and the middle tone is above the unglazed, but when it comes to the dark part, its curve falls below the unglazed gray balance curve

the stability of the printed matter before and after glazing

the variation in the middle tone is large (relatively unstable), but the variation (instability) tends to slow down after reaching the dark part

the larger the point, the larger the variation. (the more unstable)

II. Visual experience

for 50 students, for "unglazed posters, posters with UV light and posters with PP fog light, which one gives you the best visual experience? Why?" A simple questionnaire survey shows that:

(I) five of the 50 students like unglazed posters: because they look more natural

(II) 17 of the 50 students like UV glazing posters: because the colors look bright, reflective, bright and attractive, the posters feel more realistic, the products (patterns) look realistic, three-dimensional, and the color of PP fog glazing is suppressed, so they don't like it

(III) 28 of the 50 students like PP fog light poster: because the poster looks more textured, comfortable, soft, natural, beautiful, advanced, exquisite, not dazzling, the eyes do not feel reflective, the visual feeling is higher, and the poster has a sense of value. Conclusions and suggestions: posting posters is a way to convey goods and information. It is very important to strengthen the surface effect of posters

whether the poster is polished or not really has a great impact on the visual experience. According to our questionnaire survey, only 5 of the 50 people like unpainted posters, while the remaining 45 people like unpainted posters. It shows that an unglazed poster looks ordinary and unattractive, which is easy to turn a blind eye and lose its function. However, the illuminated posters add a sense of beauty and show a delicate visual feeling as if they had been melted

the different types of glazing bring different visual feelings. Visually, it is obvious that the poster with UV glazing has a higher color brightness, which shows how to refuel the universal tensile testing machine: get more bright and saturated, and increase the color effect of the poster. The hue with high brightness, high chroma and long wavelength can make people excited, (Li Changjun art and Visual Psychology) has the effect of strengthening attraction. While PP fog surface glazing suppresses the expression of color, and the extinction technique produces a little hazy visual feeling. Although the color is no longer so bright, it creates a visually soft texture effect. The choice, separation, cognition and understanding in vision often affect psychology through the brain

for color, color appeals to feeling, and color produces an immediate effect and becomes a symbol. Glazing can highlight the inherent color, but it destroys the color under excessive action. Too bright color will cause psychological unhappiness, trouble and disgust. In terms of the brightness of colors, a moderate sense of brightness stimulates the feelings of pleasure and excitement in people's emotional induction. Posters with UV light have a bright film more than posters without UV light, resulting in an increase in color saturation, and people's visual viewing has driven a happy mood

soft colors will cause people to have a quiet and peaceful mood. The poster color after PP fog light is excellent and detailed, which visually affects the psychology and has a calming effect. The mood is soothed, which also creates a soothing function

poster glazing is helpful for posters, but what kind of lighting is needed should be selected according to the design content of posters. Lively, vivid, happy and exciting design content is more suitable for bright glazing, while gentle, beautiful and warm design content is more suitable for soft glazing. Now there are many glazing methods that prefer local glazing to create more exquisite visual enjoyment to cope with changing consumers. We can explore more about the visual feelings of the public in order to stimulate different glazing performance methods and give people more different visual enjoyment
