Pad printing is a popular printing method used to transfer ink from a printing plate onto a substrate with the help of a soft silicone pad. It is widely used for printing on irregularly shaped objects such as the manual station trigger plate of an injection fire alarm device.
The manual station trigger plate is an important component of a fire alarm system. It is used to manually trigger the alarm in case of an emergency. The plate is made of plastic and has a raised button that needs to be printed with the word “FIRE” in red for easy identification.
To achieve high-quality printing on the manual station trigger plate, pad printing is the most suitable method. It allows for precise and consistent printing on the raised button without damaging or scratching the surface of the plate. The process involves the following steps:
1.Preparation of the printing plate: A printing plate with the image of the word “FIRE” in reverse is made using photo-polymer technology.
2.Ink preparation: A special type of ink that can adhere to plastic surfaces and withstand extreme temperatures is prepared.
3.Ink application: The ink is applied to the printing plate, and the excess ink is removed with a doctor blade.
4.Pad preparation: A soft silicone pad is used to pick up the ink from the printing plate and transfer it onto the manual station trigger plate.
5.Printing: The pad is pressed onto the raised button of the trigger plate, transferring the ink onto it.
6.Drying: The printed trigger plate is left to dry for a few hours before it is assembled into the fire alarm device.
In conclusion, pad printing is a reliable and efficient method for printing on the manual station trigger plate of an injection fire alarm device. It produces high-quality and durable prints that meet the safety standards required for such devices.
