Post-glazing color differences and visual perception

First, the color difference after polishing The most commonly used glazing method is PP glazing and UV glazing, but now the color difference is analyzed by unglazed, PP matte surface, and UV glazing.
After the glazing process, the reproduction of the printed matter has a relatively large influence, and the common point is that the concentration range of the bright portion and the intermediate tone is increased, and the condensed region of the dark portion is compressed. According to Sun Yizhi's "Study on Color Differences in Pre- and Post-printing Applications," we can find:
Coating type UV coating PP matte surface effects of the full version of the printing ink concentration greater than unglazed.
Less than unglazed.
The yellow version of the printing plate was higher than the unglazed, but the blue, magenta, and black plates were larger than the unglazed plates, but did not significantly change the reproduction concentration.
Both are smaller than unglazed, but the range of change is large.
The dot enlargement situation is larger than the unglazed from 10% to 90%.
Intersections between 80% and 90% of the dots intersect unglazed dot gain curves less than unglazed.
Hue difference and non-glazing are not much different.
Better than not polished.
There is no difference between gray and unglazed.
Better than not polished.
Effectiveness is not much different from non-glazing.
Better than unglazed.
Printing ink has an increasing trend.
There is a weakening trend.
Chromatic aberration has a greater response to color patches of dots.
For color dots, the response of color patches is small.
The print contrast value of the print contrast flat screen is less than the unprinted print contrast value.
The relative printing contrast value of the flat screen is less than the unglazed printing contrast value.
The gray balance curve, regardless of color, is located on the unglazed gray balance curve.
The gray balance curve of the highlight and midtones lies above the unglazed, but in the shadow region, the curve falls below the unglazed gray balance curve.
The stability of the printed matter before and after polishing was greater in the midtones, and (less stable) but the variation after the darkness (instability) slowed down.
With the enlargement of outlets, there is a large variation. (more unstable)
Second, the visual sensation of the 50 students for the "Unglazed posters and posters on UV light and PP matte light, which one gives you the best visual experience and why?" A simple survey found:
(a) Five of the 50 students like the unglazed poster: Because it looks more natural.
(B) 17 out of 50 students liked the UV varnish poster: because the colors look bright, there are reflective effects, brighter and more attractive attention, the poster feels more realistic, the product (pattern) looks realistic, three-dimensional, PP The color of the light on the matte surface is suppressed, so I do not like it.
(c) Of the 50 students, 28 were fond of the PP matte light poster: because the poster appeared to be more textured, comfortable, soft, natural, beautiful, advanced, delicate, non-glareous, the eyes did not feel reflective, and the visual experience was higher , posters have a sense of value. Lu, conclusions and recommendations: Posting posters is a way of conveying goods and messages. It is important to strengthen the poster surface effect!
Whether the poster is polished or not has a great influence on visual perception. According to our survey, only 5 out of 50 people like unglazed posters, and the remaining 45 people are fond of light posters. Showing an unglazed poster seems ordinary and unattractive, it is easy to turn a blind eye and lose its effect. However, the lighted poster was just like the one that added the beauty of the one, and it also showed an exquisite visual feeling!
Different types of glazing bring different visual perceptions. Visually speaking, it is obvious that the poster color of UV varnish posters is brighter and appears more saturated, which increases the color effect of posters. Brightness, high chroma, and long-wavelength hue can make people excited. (Li Changjun Art and Visual Psychology) has an attractive effect. The surface of PP fog suppresses the expression of color, and the extinction method produces a little bit of a visual experience. Although the color is not so vivid, it creates a visually soft texture effect. The choice, separation, cognition and understanding in the vision often affect the mind through the brain.
In terms of color, color appeals to feelings. Color produces an immediate effect and becomes a symbol. Glossing can brighten the inherent color, but under the excessive effect it destroys the color. Too bright colors can cause people's psychological unhappiness. Troubled and disgusted. In terms of bright colors, moderate brightness evokes pleasure and excitement in human emotions. The posters with UV light added a brighter film than the non-lighted posters, resulting in an increase in color saturation and people's visual emotions.
Soft colors will cause people to produce a quiet, peaceful mood. The color of posters after PP fog is excellent and meticulous. The visual influence of the mind produces a calming effect, and the emotions are soothed, which also creates a soothing function.
Poster glazing is helpful for posters, but what kind of light needs to be selected should be matched with the design content of the posters. Lively, lively, pleasant and exciting design content is more suitable for bright glazing techniques. The gentle, beautiful and warm design is more suitable for soft glazing. Many glazing methods are now biased towards partial glazing, creating more refined visual enjoyment in response to changing consumers. For the public's visual experience can be more explored, in order to be able to inspire different ways of glazing performance, giving people a different visual enjoyment!
