Poster glazing has a visual impact

The use of glazing technology in print jobs has become part of the printed structure! Because glazing can increase the water resistance and wear resistance of printing, it has the function of improving the quality and aesthetics of the printed matter. Nowadays, with the demands and attentions of consumers, glazing has become a part of the current printing industry that cannot be ignored. The glazing of the poster is mainly to take its protection function, so that its products can remain intact and attract customers' eyes. The printed matter is bright, and the solvent dissolves the pigment in the ink more easily, resulting in a color difference, and there may be a difference in the visual perception.

Therefore, this paper selected unglazed posters and posters on UV light and PP fog to discuss visual influences and visual perceptions.

Preface

I. Research motivation and purpose

There are many advertising posters nowadays designed to be very refined and beautiful, with more and more attractive feeling! In particular, the light on the surface of the poster is even brighter. Paper glazing is not only beautiful but also has a protective effect. It has good help for paper. Advertising posters need to be such! Because the poster is a kind of printed media that conveys information to the public (Zou Yongsheng's application of visual rhetorical techniques in graphic design), improving the visual experience on the surface of the poster helps visual communication. However, the problems of color difference and network dot variation after paper coating have existed, and what kind of effect will it have on visual effects? And whether the poster is glazing or not, what kind of feeling will it have for the visual? It will be the subject of this article.

Second, the scope of research

Due to the wide variety of glazing, depending on the application, it can be divided into publishing, papermaking, and special performance applications. The poster is a publishing product. The most commonly used coating methods are PP and glazing and UV glazing....Because of the great difference between PP matte and UV glazing, this article chooses both Three kinds of posters such as polishing are compared.

Third, research structure

Discussion of literature

Unglazed and UV light and PP matte finish posters

Questionnaire survey

Analyze visual perception and influence

Conclusion and suggestion

è´°, poster features

First, the poster

A poster is a notice posted at a specific location when the group publishes a message. It is also a media that disseminates information to the general public. (Ou Hyo-Ming applied chromatics) It is a kind of print media, there is no sound effect, can only strengthen the message through the shape and color, so the highlight of the color is an important point! People usually look at posters for a short period of time. They want to know the content of posters within about two to five seconds. Therefore, the appropriate increase in brightness, the application of psychological color effects, the use of aesthetics and decorative colors ..... All of these contribute to the effect of communication, which has caused the poster to persuade, identify, communicate, and aesthetically function.

The essentials of posters to create visual appeal:

(a) Adopt correct visual forms for objects and advertising purposes.

(b) The power of contrast.

(C) simple, simple non-monotonous, simple is not necessarily complicated.

(D) to grasp the different freshness, re-combination of new creations.

(e) The power of conflict.

(6) The consistency of form and content makes the attraction profound and meaningful.

(Application and discussion of Zou Yongsheng's visual rhetoric skills in graphic design)

Second, the characteristics of the poster

(a) The location of posting can be freely chosen

(B) Make it bold in size and color

(c) long posting time with repeated publicity

(D) can be posted in the same location to enhance visual effects

(E) Suitable for key advertising (Zou Yongsheng visual rhetoric skills in graphic design

Applications and Discussion)

Poster color appeal:

Convey the message of product color

The psychological effect of using color

Strengthen the use of color impression techniques

Good posters must anticipate the viewer’s psychological reactions and feelings in advance in order to resonate with the content conveyed by the viewers! (Ou Siming Applied Chromatics)

The function and characteristics of enamel and glazing

First, the function and purpose of polishing

After the printing is finished, glazing adds a protective layer on the surface of the paper. The purpose is to protect the imprint from being scratched and to increase the abrasion resistance of the printed material. After the surface has been polished, the bright surface is lighted. The entire print produces gloss, and the matte light produces a protective layer of mist and fog, both of which increase the water resistance of the print and protect it from moisture and paper. Printed materials can enhance the aesthetics of prints by using bright glossy materials or matte matte materials. Bright surfaces can give prints a high degree of clarity and gloss. Fog surfaces have no bright and dazzling impression. Printed colors. "Poster" is a print media that disseminates information to the public in a large amount. The expression of glazing changes the visual appeal of the poster, increases its visual effects, attracts more attention, and protects the poster from getting wet with rain. Prevent scratches and increase the value of posters!

Second, all kinds of coating methods and characteristics

(I) Various types of coating methods

The glazing method can be divided into light and fog on the bright surface - bright surface is:

(1) Lubricating oil: The operating mode of the glossy oil is the one-time printing of the connection between the printing machine and the coating machine, and it can also be used as the second coating mode of the non-wired connection. As with printing inks, no special equipment and operating techniques are required. Its advantages are easy operation and low cost.....but disadvantages can cause air pollution, odor, and time.

(2) PVA glazing: using a coater and a high temperature calender, high-temperature baking was performed to volatilize the solvent to harden the PVA. The advantage is that the cost is lower and cheaper. In the process of drying, formaldehyde will release toxic substances such as formaldehyde, which will greatly harm the health of operators.

(3) Film lamination: The adhesive film of PP bright surface, PP matte surface, rigid PVC, PET... is coated with an adhesive, dried, and then pressed together with a printed matter to complete the lamination. The glossiness and abrasion resistance of the film are the best in all kinds of glazing, but the expensive paper that is processed by the film cannot be easily recycled and cannot be recycled. It does not meet the requirements of environmental protection!

(4) UV glazing: The technology of fast drying applies the acid-base varnish with a photosensitive substance to the glazing material. After ultraviolet ray irradiation, photopolymerization chain reaction takes place instantaneously to form a glossy and transparent surface morphology. The advantages are high gloss and good abrasion resistance, but the disadvantages are that UV polishing is toxic, there is irritating damage to the human skin, eyes and respiratory system, the equipment is expensive, and it is not easy to reconstitute pulp to make recycled paper.

(5) Waterborne coating: Water is the basic volume, styrene or acrylic is the solute, and weakly inert solvent is the surfactant. The liquid water-based glaze is in the form of an emulsion. After the coating is dried and hardened, it is a clear acrylic film. Its advantages are low price, no toxicity, no harm to the operator's health, high gloss, good abrasion resistance, quick drying effect, easy re-slurry decomposition, manufacture of recycled paper, and no environmental pollution!

There are:

Adhesive film lamination: It is used to coat adhesive films such as PP bright surface, PP matte surface, rigid PVC, PET..., etc. Fog surface effect.

(II) Comparison of various types of polishing properties

Glazing type characteristics and brightness

Bright oil brightness, poor wear resistance

PVA
Bright, poor wear resistance

UV
Good brightness and good abrasion resistance

Oily PP
(Bright and Fog) Good Brightness, Good Abrasion Resistance, Solvent Containing Toluene

UVPP
(bright and fog) Good brightness, good abrasion resistance, good adhesion

Water-based PP
(bright and fog) Excellent brightness, good abrasion resistance, and good adhesion

Water-based PP (PU glue)
Excellent brightness, good abrasion resistance, excellent adhesion, especially for long fiber paper
