Clear and legible coding on plastic products plays a critical role in industrial production processes. An effective coding process is especially necessary for product tracking, quality control and consumer information. It is of great importance for manufacturers and consumers that the coding on plastic products is always clear, legible and long-lasting. In this article, we will provide detailed information on how to make clear and legible coding on plastic products, the methods used and their advantages.
1. Coding Methods on Plastic Products
Coding operations on plastic surfaces are generally carried out by the following methods:
a) Inkjet Printers
Inkjet printers are one of the most common methods of coding on plastic products. These printers create text or graphics by quickly spraying drops of ink onto the plastic surface. Inkjet printers are often preferred for fast production lines because they can print high-quality text quickly.
b) Laser Marking
Laser marking is a technology that can make permanent and legible codes on plastic surfaces with high precision. This method is based on the principle that laser light heats the plastic and codifies it. Laser marking is particularly ideal for permanent and durable markings. Laser marking is suitable for products that require high quality and detailed coding.
c) Thermal Transfer
Thermal transfer printers print high-quality text on plastic surfaces using special transfer tapes. These printers are often used for labeling processes. Thermal transfer technology is particularly preferred for producing durable and long-lasting labels.
d) Hot Stamping
Hot stamp technology creates metallized prints on plastic surfaces, resulting in sleek and professional looks. This method is often preferred for cosmetic packaging and luxury product labels. Hot stamping is used especially for aesthetic appearances.
2. Tips for Clear and Legible Coding
When coding on plastic products, it is of great importance that the codes are clear and legible. Here are some tips for clear and legible coding:
a) Use High Quality Printers
The quality of the printers used for coding directly affects the clarity of the printed text. Printers that offer high resolution produce clearer and more legible codes. Quality options such as inkjet printers, laser marking machines and thermal transfer printers always give clearer and more permanent results.
b) Choosing the Right Ink
The type of ink used for coding should be chosen depending on the type of plastic and the conditions of use of the product. UV inks provide durable and long-lasting prints on plastics. Also, the drying time and quality of the ink should be taken into consideration.
c) High Resolution Settings
It is important to set the resolution settings correctly on coding machines. High resolution printers can produce clearer and more detailed codes. Also, the printing speed of the printer needs to be set correctly. Printing too fast can result in fuzzy codes.
d) Surface Cleaning
A clean plastic surface for coding improves the quality of the text. There should be no dirt, dust or oil on the plastic surface. Surface cleanliness is essential for printers to make ink properly.
3. Technological Developments to Improve Coding Quality
The technologies used in coding processes are constantly evolving. In recent years, inkjet printers and laser marking machines that offer higher resolution have taken their place in the market. These technologies offer faster and clearer coding. In addition, developments in ink technologies provide more durable and aesthetic appearances on plastic products.
4. Things to Consider When Coding on Plastic Products
Coding on plastic products is often necessary for product tracking and quality control. However, some important points should be taken into account when coding:
- Plastic Type: Each type of plastic requires a different printer and ink type. Therefore, the material and printer compatibility should be carefully selected.
- Coding Area: The size of the area to be coded can affect the choice of printer. Inkjet printers can be preferred for small areas and laser marking machines for large areas.
- Readability: Codes must always be legible. To ensure this, it is important to choose the right font, size and color.
Conclusion
Clear and legible coding on plastic products can make production processes more efficient and products easier to track. When performing this process, it is important to choose the right technology, use quality printers and ink, and ensure cleanliness and correct resolution settings. Correct coding in industrial production always ensures better quality and effective results.
