Embossing is a special technology in the surface treatment and processing of paper bags. The use of embossing can give the paper bag a three-dimensional effect. Embossing process is one of the commonly used techniques in post printing processes, With the main purpose of emphasizing the local surface of the overall design, Highlighting the important position of the local area, And having rich layers in the overall structure, Adding more and stronger artistic value. Moreover, it is an environmentally friendly process, And its production process is pollution-free. The concave convex process is more capable of showcasing a strong stereoscopic visual experience and a good touch.
1. Process characteristics
The embossing process is an environmentally friendly process, And its production process does not cause any pollution. In today's era of advocating green, The use of this processing can emphasize the user's environmental protection concept. The use of embossing on gift paper bags can give them a three-dimensional effect, And the overall structure also has rich layers, Adding more and stronger artistry. It can replace traditional fonts, colors, and other methods to showcase the core content, emphasize a certain part of the overall design, And highlight its important position.
2. Material characteristics
According to different design requirements and printing quantities, The material selection of the embossing template may vary. The template materials are different, And there are also significant differences in production costs, process effects, and printing quantity. In the production of embossing, in addition to selecting the appropriate printing plate, The appropriate paper is also crucial for achieving a good embossing effect. The thickness of paper and the surface texture can affect the performance of details.
Usually, Paper with a weight of over 180g/m2 is suitable for embossing, But this is not an unchanging standard. If the paper is too thin, it is very easy to break during embossing.
A sufficiently thick and resilient paper is the foundation for presenting printing effects, Especially for paper bags that require a prominent embossing effect.
Paper with long fibers usually has good toughness, And its resistance to India is better than paper with short fibers.
Recycled environmentally friendly paper is not suitable for embossing. Due to the factors of the paper itself, It may cause deviations in the effect of different pages, And it is also prone to edge cracking.
If it is a process that requires heating (such as hot stamping), It will greatly increase the probability of paper breakage. Therefore, It is even more important to choose paper carefully.
