About Flexo printing
Flexography (often abbreviated to flexo) is a form of printing process which utilizes a flexible relief plate. It is basically an updated version of letterpress that can be used for printing on almost any type of substrate including plastic, metallic films, cellophane, and paper. That’s why it’s widely used for printing on the non-porous substrates required for various types of food packaging (it is also well suited for printing large areas of solid color). By using water based inks it is also an environmentally friendly printing technique.
Hot air dryers are very conventional to use on flexo printing machines. Infrared radiationpanels are also very suitable to for drying of the ink on carton and foil. UV dryers are often used to dry the ink on aluminium, laminates or plastics.
We have developed an IR dryer to dry special coatings (sealers), which are applied in-line over the ink. This IR drypanel is equipped with carbon lamps. With this IR dryer is it possible to run in-line a higher production speed in compare with the conventional hot air dryers.
