Rotary screen printing process. As a result considerable amounts of dye paste end up in the wastewater because the volume of the machines is significant and a substantial quantity of. The machine employs a rotary screen for each color as in flat screen printing and the design for each rotary screen is made in a manner similar to automatic flat screen printing. After every printed batch the system has to be cleaned thoroughly. Screen printing is a printing technique where a mesh is used to transfer ink onto a substrate except in areas made impermeable to the ink by a blocking stencil a blade or squeegee is moved across the screen to fill the open mesh apertures with ink and a reverse stroke then causes the screen to touch the substrate momentarily along a line of contact.

In flat screen printing technology the screen is flat and moves up and down. We can discuss about the difference between flat rotary screen printing process. Beside the rotary screen is round in size and it rotates. By converting the screen printing process from semi continuous to continuous higher production speeds are obtained.

In rotary screen printing colored paste is forced through the open areas of a cylindrical printing screen that rotates as the fabric moves beneath it. Rotary screen printing enables a wide range of applications including metallic doming security printing and braille. Screens have to be cut and made to the design we require and each colour way has to be. The rotary screen printing machine is fast but limited to the designs it can print and commercially very economical way of printing.

In rotary screen printing for every colour there is a screen a supply system for the colour and a paint kitchen inventory. In contrast to intermittent flat screen printing rotary screen printing is fully continuous with fabric speeds up to 50m per minute if adequate drying capacity is available. The print finish quality of rotary screen printing is not to the same standard as modern day discharge printing machines. Typical speeds are from 50 120 ypm 45 100 mpm for rotary screen printing depending upon design complexity and fabric construction.

In flat screen printing the squeeze is used. After print application the process is the same as flat screen printing. As most of the screen printing procedures are different.
