Colored die-cut napkins: revealing the art and ingenuity of rough cutting process

1. The unique charm of colored die-cut napkins
Colored die-cut napkins, with their rich colors, diverse shapes and exquisite designs, have become an indispensable part of modern catering culture. From family gatherings to high-end banquets, from holiday celebrations to theme parties, colored die-cut napkins can always add a touch of color to the table with their unique charm, making every gathering a double feast of vision and taste. And all this beauty is inseparable from the exquisite use of die-cutting technology, especially the key link of rough cutting technology.

2. Rough cutting technology: the cornerstone of die-cut napkins
In the production process of colored die-cut napkins, rough cutting technology is an indispensable step. It is not only the basis of fine cutting technology, but also the key to whether the entire production process can proceed smoothly. In the rough cutting stage, the mold makes a preliminary cut on the material at a faster speed to form a rough outline. This process seems simple, but it actually contains rich technical details and artistic charm.

2.1 Design and production of molds
The mold is the core of the rough cutting process. Its design directly determines the shape and outline of the napkin. In the process of mold design, designers need to fully consider the purpose, style and material characteristics of the napkins to ensure that the cutting path of the mold not only meets the design requirements, but also minimizes material waste. At the same time, the material of the mold is also crucial. A high-quality mold should have sufficient hardness and wear resistance to ensure the stability of the shape and the accuracy of cutting during the long-term cutting process.

When making molds, high-strength materials such as carbide or steel are usually used. These materials not only have good wear resistance and corrosion resistance, but also maintain high temperature stability during the cutting process, thereby ensuring the stability and consistency of the cutting effect.

2.2 Material preparation and processing
Before rough cutting, the napkin material needs to undergo a series of preparations and processing. First, it is necessary to select high-quality raw materials such as cotton, linen or blended materials. These materials not only have good moisture absorption, breathability and durability, but also maintain the stability of the shape and the brightness of the color during the cutting process.

Secondly, the material needs to be pre-treated, including flattening, pre-shrinking treatment, etc. These processing steps can eliminate the stress inside the material and avoid deformation or wrinkling during the cutting process. At the same time, it can also make the material softer and easier to cut, thereby improving cutting efficiency and finished product quality.

2.3 Technical details of the rough cutting process
The rough cutting process seems simple, but it actually contains rich technical details. First, it is necessary to select the appropriate cutting speed and pressure. Cutting speed that is too fast or pressure that is too high may cause material deformation or incomplete cutting; while cutting speed that is too slow or pressure that is too low may reduce cutting efficiency and increase production costs. Therefore, in the rough cutting process, it is necessary to accurately adjust the cutting parameters according to the characteristics of the material and design requirements to ensure the stability and consistency of the cutting effect.

The cutting temperature needs to be strictly controlled. During the cutting process, friction heat is generated between the mold and the material, causing the temperature to rise. If the temperature is too high, it may cause the material to burn or deform, affecting the quality of the finished product. Therefore, in the rough cutting process, appropriate cooling measures need to be taken, such as using a cooling system to cool the mold to ensure the stability of the cutting temperature.

Attention should be paid to the planning of the cutting path. In the rough cutting stage, the planning of the cutting path directly affects the effect of the subsequent fine cutting stage. Therefore, when planning the cutting path, it is necessary to fully consider the shape, outline and requirements of the fine cutting stage of the napkin to ensure that the cutting path not only meets the design requirements, but also lays a good foundation for the subsequent fine cutting stage.

3. The artistic charm of rough cutting process
The rough cutting process is not only a technical job, but also an art. In the process of making colored die-cut napkins, the rough cutting process adds unlimited possibilities and creative space to the napkins with its unique artistic charm.

3.1 Shape shaping
The rough cutting process can shape napkins of various shapes and outlines. From simple geometric figures to complex natural landscapes, they can be achieved through rough cutting. These napkins of various shapes can not only meet different usage needs, but also add a unique landscape to the dining table.

3.2 Edge processing
The rough cutting process can also process the edges of the napkins. By adjusting the cutting parameters and cutting paths, different styles of edge effects can be created, such as smooth, wavy, serrated, etc. These edge effects can not only enhance the three-dimensional sense and layering of the napkins, but also add a unique artistic atmosphere to the napkins.

3.3 Utilization of materials
The rough cutting process also demonstrates a high level of artistry in the utilization of materials. Through precise calculation and planning, material waste can be minimized and material utilization can be increased. At the same time, the remaining materials can also be used to make other small ornaments or decorations, achieving diversified utilization and sustainable development of materials.
