A letterpress is relatively slow if a large number of prints have to be processed. The printing process can be speeded up by using a rotary letterpress, seen below. This type of printing process is usually carried out at a commercial printing company as it requires expensive machinery.

   
   
 
   
The vital parts of the rotary letterpress are:

1. The paper roll

2. The printing plate

3. The compression cylinders

 

A rotary letterpress can be used for manufacturing paper products such as wallpaper. The printing plate is usually made of aluminium and has the pattern/shape/text to be printed - embedded in its surface. As the printing plate revolves ink is spread across it and the paper is pulled between the compression cylinders and the plate. The pattern or shape on the plate is printed onto the paper.

 

This technique was used until the 1980s/90s to print newspapers, and magazines although it is still used to print wallpaper and fabrics.

   

   

 

 

Explain how the rotary letterpress works - use notes and diagrams for each stage.
