Reflective signage has a wide range of applications. Reflective signages are installed on many highways and railways, which has a good effect and greatly eliminates hidden safety hazards. Reflective film signs were initially only used in more important areas due to price reasons. With the development of technology and fierce competition, the price of reflective signs has gradually decreased. Now many places have installed reflective film signs.
The production of reflective signs is more difficult than the production of ordinary signs. Generally, engineering grade reflective films are used to make signs. The solvent resistance of the reflective film, the drying time of the ink, the reflective effect after printing the pattern, etc. must be considered.
1. The choice of ink: choose ordinary color ink printing pattern, the produced reflective logo has poor reflective effect, because the pigment contained in the ink is inorganic pigment, with opacity, although the color is bright, but it covers the reflective effect; use outsourcing Reflective ink printing, the produced pattern has good reflective effect, and the performance of all aspects meets the requirements for use. However, due to the small amount of reflective ink, more colors are required, and sometimes the need to adjust the color, you need to buy a variety of reflective ink Reserves have caused a backlog of funds and higher costs. The method of using self-made reflective ink can be formulated according to the amount used, which will not cause a large amount of ink remaining, and the price will be lower than that of purchased ink.
Second, the production of reflective film identification signs: First of all, the preparation of reflective ink, choose a good transparency ink, will not reduce the reflective effect, and easy to color. At the same time, the ink should have self-drying or low-temperature drying, and the drying time should be controlled below 30mm to prevent the reflective film from being bitten by the solvent; the dye should choose a transparent organic dye, so that the reflective film maximizes the reflective effect, and the organic transparent dye First prepare into mother liquor, the solvent can choose xylene, and the concentration should be selected according to the supplier's instructions.
According to the customer's requirements, choose and match the color, add the prepared mother liquor to the transparent ink, and then add the amount to be determined after a small trial to avoid waste. The viscosity of the ink must be appropriate. Generally, the viscosity of the ink is lower than that of other hard logos to avoid sticking the plate. However, the viscosity should not be too small. Otherwise, it will cause the phenomenon of paste plate and cannot meet the printing requirements of high-precision patterns. The printing of the reflective film is not related to the ordinary substrate. It can be dried naturally or dried at low temperature after printing.
Nylon dog leash (also called a lead, lead line or tether) is a rope or similar material used to control an animal by attaching it to a collar, harness, or halter. In British English, a leash is generally for a larger (possibly dangerous or aggressive) animal, with lead being more commonly used when walking a dog.
