What is rotary screen printing?
?
In rotary printing, the web travels at a consistent speed between the screen and a steel or rubber impression roller immediately below the screen. (The impression roller serves the same function as the press bed on a flatbed press.) As the web passes through the rotary unit, the screen spins at a rate that identically matches the speed of substrate movement.
?
?
Rotary screen printing is so named because it uses a cylindrical screen that rotates in a fixed position rather than a flat screen that is raised and lowered over the same print location. Rotary presses place the squeegee within the screen. These machines are designed for roll-to-roll (web) printing on flexible materials ranging from narrow web films to wide-format roll textiles.
?
?
The squeegee on a rotary press is in a fixed position with its edge making contact with the inside surface of the screen precisely at the point where the screen, substrate, and impression roller come together (Figure 1). Ink is automatically fed into the center of the screen and collects in a wedge-shaped & quot;well& quot; formed by the leading side of the squeegee and the screen& acute;s interior surface. The motion of the screen causes this bead of ink to roll, which forces ink into stencil openings, essentially flooding the screen without requiring a floodbar. The squeegee then shears the ink as the stencil and substrate come into contact, allowing the ink to transfer cleanly to the material.
?
In short, rotary printing is a continuous, stepless image-transfer method. The geometry of the screen and the position of the squeegee within the screen combine to provide both the screen-flooding and image-transfer functions in a single smooth operation that repeats with every revolution of the screen.

Rotary Screen Printing…
Rotary screen printing uses woven metal mesh to support an ink-blocking stencil. The stencil forms open areas where ink and printable chemistry is forced out. The ink transfers to the substrate using a roller or blade. One color prints per screen, so several screens can be used together to create high quality, multi-colored designs. The substrate is guided by a belt under the cylinders that rotate in a fixed position. These machines print on continuous roll fabric (both woven and nonwoven).
