Rotary Screen Printing Process

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 process.

A printing machine that utilizes seamless cylindrical screens made of metal foil was originally developed in holland. By converting the screen printing process from semi continuous to continuous higher production speeds are obtained. 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. In rotary screen printing for every colour there is a screen a supply system for the colour and a paint kitchen inventory.

Beside the rotary screen is round in size and it rotates. The rotary screen printing machine is fast but limited to the designs it can print and commercially very economical way of printing. 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. 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.

We can discuss about the difference between flat rotary screen printing process. Less than 30 minutes are required to go from the repro film to the ready to use printing stencil. Have a question need a quote. The print finish quality of rotary screen printing is not to the same standard as modern day discharge printing machines.

This process is called rotary screen printing. In flat screen printing the squeeze is used. Screens have to be cut and made to the design we require and each colour way has to be. After print application the process is the same as flat screen printing.

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. Typical speeds are from 50 120 ypm 45 100 mpm for rotary screen printing depending upon design complexity and fabric construction. As most of the screen printing procedures are different.
