Ink cups for pad printing machines
There are many types of Ink cups for pad printing machines. These come in a variety of types and styles. Initially, pad printing equipment utilized inkwell doctor blade systems. With time, sealed or closed cup systems have replaced doctor blades. In the USA sealed ink cups pad printing machines have gained popularity. While in other parts of the world, doctor blade systems are still in use. While both types of inking systems have a great deal of merit, as a new equipment you need to understand the pros and cons of both systems. Check out our wide variety of pad printing ceramic rings! Let us look at the different types of doctoring systems in detail.
Doctor Blade System
Doctor blade system consists of an ink well, a doctor blade, and a flood bar. The doctor blade system is also known as open inkwell system. Open ink well systems are older methods of pad printing ink supply. This method uses an ink trough to hold ink. The ink trough is located behind the printing plate. A flood bar pushes printing ink over the plate. Then a sharp blade (doctor blade) removes the ink from the plate surface, leaving ink on the etched artwork. The ink filled in the artwork is then picked up by the printing pad. Check out (Pad) printing machine – ResearchGate
