Industry Knowledge| Stamping Process

Hot stamping is an important metal effect surface decoration method, although gold and silver ink printing and hot stamping have similar metallic luster decorative effect, but to get a strong visual impact, or through the hot stamping process to achieve.

Due to the continuous innovation of hot stamping equipment and supporting materials, enriching the expression of hot stamping techniques, now hot stamping process mainly has 7 kinds:

1:ordinary flat ironing

The most common hot stamping, leaving white around to highlight the hot stamping body. Compared to other stamping, the production process is relatively simple, and if the number is not large, zinc plate stamping can be used.

Flat stamping, refers to the datum surface is flat impression, stamping on a flat workpiece or a part of the plane of the workpiece.

This kind of stamping, can be convex graphics, stamping on a flat surface; can also be flat silicone plate, stamping on the raised graphics.

2: field anti-white stamping

The opposite of the flat ironing production method, the subject part of the white, and in the background part of the stamping, stamping area size according to product design needs, if the stamping area is larger, need to consider its adhesion performance to meet the process requirements.

3: overlay stamping

According to the needs of the picture, in order to make the stamping and printing part of the clever combination, first printing before stamping. The process of production is high for registration and requires accurate alignment to get the perfect effect.

4: refractive foil stamping

Stamping version production, the main image and the background graphics with different thickness or towards the line as a partition, forming a refractive effect, emphasizing the graphic line art sense, usually using laser engraved version.

5: multiple stamping

In the same graphic area repeated stamping more than twice, need to go through multiple process, but also must pay attention to two kinds of gold foil is compatible, in order to prevent the phenomenon of adhesion is not firm.

6: embossed stamping

The same practice as stamping and then embossing, but embossing stamping pay more attention to the stamping texture rather than embossing effect, usually using embossing stamping version, the height of the raised needs to be in the gold foil surface tension can bear range.

After the relief stamping technology processing products show relief-like three-dimensional pattern effect, so the use of first print and then stamping process method, and because of its high precision and high quality requirements, more suitable for the use of hot stamping technology.

As you can imagine, designers have to carefully consider texture, weight, gold foil and ink when selecting paper or other carrier materials for a three-dimensional foil stamping process, and alignment of the front and back side is critical.

At the same time, the thickness of the paper will limit the quality and effect of your finished product during the process. For example, paper that is too thin or less tough can lead to problems with paper popping.

7: special effect texture stamping

According to the creative needs, the production of special effects texture stamping, highlighting the different special mechanism effect.

In the practical application of hot stamping process, the choice of metal stamping plate, hot stamping paper, paper, hot stamping expression form several directly affect the final hot stamping effect.

Hot stamping is nowadays widely used in various printing and packaging fields. It is also the only printing technique that produces a shiny, non-tarnishing metallic effect on paper, plastic, cardboard, and other printed surfaces.
