Embossing

Process principle

The concave-convex process is to make the surface of the paper form a three-dimensional effect higher or lower than the plane of the paper through the prefabricated engraving model and the action of pressure. Concave and convex embossing is also called embossing process, in which the process of bulging the surface from the back of the paper by leave pressure is commonly known as "convex"; while applying pressure from the front of the paper to depress the surface is called "concave", which is a printed matter The main purpose of the common technology in the surface finishing process is to emphasize a certain part of the overall design to highlight its important position.

In this process, a set of concave-convex printing plates (male and female) are made according to the designed graphics, and the large pressure of the relief printing machine is used to roll out a three-dimensional space in the partial graphics that have been printed or in the blank. magnesium etching printing plate The graphics make the printed product have a three-dimensional effect, and the entire structure also has rich layers, adding more and more intense artistry.

use

The embossing process is an environmentally friendly process, and there is no pollution in the production process. It is widely used in the market, ranging from high-end fashion products to business cards. magnesium etching printing plate The concave-convex process has become the mainstay of the printing and packaging and graphic design industries.

One of the most common process technologies.

Common printed materials include: exquisite book covers, gift packaging, advertising leaflets, posters, handbags, cosmetic boxes, envelopes and letterhead, children's calligraphy and painting books, etc.

Concave-convex embossing is also widely used in paper surface processing. Many foreign manufacturers produce professional machines for paper processing. The textures are diverse and have very special artistic effects.

Types of bumps

Heat bump

The selection of suitable materials and proper heating are the two elements of thermal bumping. First, outline the lines of the graphics and make the template. When the pressing machine is heated to the appropriate temperature, the contact surface of the template will be slightly burned. The paper leaves traces on the surface of the paper while forming the artistic effect of depressed lines and slightly convex middle parts.

Bronzing convex

As the name implies, hot stamping and embossing refers to the use of the same template, and the hot stamping and embossing are completed at one time. In the hot stamping electrochemical aluminum process, this process is called three-dimensional hot stamping. The template of the stamping and embossing is generally made of brass material, which can improve the accuracy of stamping and embossing. In addition, the printing material must comply with the physical principles of stamping and embossing at the same time.

Template type

The process technology and equipment of embossing are simple, and it is not very difficult to produce a single-layer embossed printed matter. The main technical points are: pressure and making templates. There are zinc plate, magnesium plate, copper plate and so on. According to the complexity, size, depth and angle of the embossing plate, the price of embossing plate and processing technology are also different. You can use only one level of flat patterns with beveled edges or rounded edges as etching print-style master molds to achieve a beautiful concave-convex effect; or use a large number of different levels of engraving and etching-type master molds to make Pursue a more three-dimensional effect. Obviously, the more sophisticated the design, the more cost to make the template.

Angle and depth of the template

The angle of the beveled edge of the template refers to the angle formed by the edge of the graphic and the line perpendicular to the template, and the depth of the concave-convex refers to the height of the convex part of the male mold or the depth of the concave part of the female mold. These are two important data that determine the effect of the process, the bevel The angle value is generally 30 degrees. 45 degrees, 50 degrees or 60 degrees.magnesium etching printing plate  For example, a 30-degree angle can only form the slope of the edge of the graphic, while a 60-degree angle can show a larger bevel effect.

Depth is very important for designers who need to create rich three-dimensional relief effects. Obviously, the deeper the template, the easier it is to get clearer and sharper graphics. In order to reduce the impact of the template on the paper, it is necessary to increase the angle of the inclined side appropriately, but this rule must be understood; too large an angle of inclination will offset the effect of depth rendering, resulting in blurred graphics edges.

When choosing the depth of bumps, you should also test the printing material. magnesium etching printing plate Thicker materials can withstand greater depths but should be pressure tested to ensure that the design effect does not appear to be broken. The depth numbers commonly used are 0.01cm, 0.015cm, 0.02cm, and 0.025cm.
