195M Toughness Rotary Nickel Screen Safely Operation And Multiple
Our rotary screen advantage:
Open area up to 18% ,there is no factory in china can make it except our factory,it
help smooth throughout of dyestuff paste, so that printing speed
and efficiency of printing machine can be ascended,experiments have
proved that up to 19% of paste volume can be saved at multiple
printing mills around the world.
•More tough and tensile, safely operation and multiple use
•orderliness and accurate screen caves, good dye output and osmotic
•Good symmetrical, good conglutination function of photosensitive

What is rotary screen printing?
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 substrate may continue through a drying unit after printing.
Subsequently, it may be directed to a rewinding unit or on to
another printing or finishing operation configured inline with the
rotary press. With standalone flatbeds and multicolor in-line
systems, getting the printed sheets to other finishing areas
usually requires more cumbersome and time-consuming manual handling
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 "well" formed by the
leading side of the squeegee and the screen'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.
