CE approval Flat silk Winning lottery screen printer:screen printing machine with vacuum table //
Usage and characters
Lottery tickets are issued by government-authorized agencies for the purpose of raising funds. They are used to randomly determine the winning numbers or results. Generally, the numbers are covered by a printed metal layer, and users can determine whether they have won by scratching off the covering layer.
- High coverage:Ensure that the metal covering layer can completely cover the numbers, and there should be no bottom penetration, so the screen printer can print once or multiple times.
- Partial overprinting: Using a positioning system, CCD alignment technology can be used for higher requirements. It must be ensured that the metal layer only covers the areas that need to be covered, and the areas that cannot be covered cannot be covered. It is necessary to ensure that the metal layer can be solidified on the numbers, but when scraped off with a hard object, the metal layer can be removed.
- Quality inspection: Winning lottery tickets involve privacy and fairness, and printing quality is very important. If necessary, an online quality inspection device is installed to detect the printing quality of lottery tickets in real time to avoid the production of defective products.
The screen printing process of scratch lottery tickets is a special screen printing process. It does not require the ink layer to have strong adhesion, but requires sharp objects to remove the ink layer, so as to realize the on-site interaction between the scratch lottery tickets and the participants in commercial activities. The printing of scratch lottery tickets has the following characteristics:
1. The scratch layer must meet the requirements of "easy to scratch, opaque, and no residue after scratching". It must have a certain adhesion and cannot fall off casually, and it must also ensure the scratchability. Usually a low mesh screen (80-120 mesh) is used to ensure that the thickness of the ink layer is uniform (usually 50-100μm).
2. The scratch layer is designed with a hollow solid pattern, and the ink accurately covers the prize area through the screen. The edges must be neat to avoid light leakage or incomplete coverage.
3. The screen printer uses a vacuum suction table screen printer, which requires precise positioning. General electric screen printers and pneumatic screen printers can meet the requirements. If a servo-driven screen printer is used, the effect will be better. In addition, in order to improve production efficiency, a production line can be formed by connecting the unloading robot and the IR tunnel drying furnace.

What is CE-Approval screen printing machine?
It refers to a screen printer that has passed the EU CE certification. CE certification is a series of mandatory standards and requirements formulated by the EU for product safety, health, environmental protection, etc., aimed at ensuring the free circulation of products in the EU market and the safety and rights of consumers. For a screen printer to obtain CE certification, it needs to meet the requirements of relevant directives and coordinated standards in terms of mechanical safety, electrical safety, noise level, electromagnetic compatibility, etc. For example, the machine's protective device must be able to effectively prevent operators from contacting dangerous parts; the electrical system must have good insulation performance and grounding measures to avoid the risk of electric shock; at the same time, the noise generated by the machine during operation must be controlled so that it does not exceed the specified limit. Passing the CE certification means that the screen printer meets the relevant EU standards and can be legally sold and used in the EU market, which also reflects the high quality and safety of the product to a certain extent.
