The superior control over coating application, provided by the slot die method, is attributable to its constant application rate.

Thus, slot-die coating acts like an obstructed dip-coating process, allowing precise control over layer thickness and increasing the speed of coating.

Slot die coating is an extremely versatile deposition technique in which a solution is delivered onto a substrate via a narrow slot positioned close to the surface. A major advantage of the slot die coating method is the simple relationship between wet-film coating thickness, the flow rate of solution, and the speed of the coated substrate relative to the head. In addition, slot die coating is capable of achieving extremely uniform films across large areas. The Ossila Slot Die Coater, for example, can produce coatings with variations lower than 5% across many meters and a variation of < 50 μm variation over 100 mm (0.05%). Slot die coating is one of many methods that can be used to deposit a thin liquid film onto the surface of a substrate. One of the main advantages of slot die coating over traditional

Despite having identical purposes, inkjet printing and slot die coating differ in terms of accuracy and flexibility. This contrast is embodied in the Easycoater, a third-generation high-tech coating machine.
