Offset Rubber Blankets- Data-1


(Written by  N.R. Jayaraman)

Some useful data for  Rubber Blankets for Offset Printing.  No single 
source of information is available that gives the  varieties of  Rubber 
Blankets  manufactured by different firms  for Offset Printing machines. Therefore I have compiled the data to the best extent possible  
from  different sources so that it will benefit of  Students and others  in 
Printing appearing for interviews and exams.

The Printers know that  Rubber Blankets play an important role in the Offset printing process as it is the intermediate medium that transfers the images on to the printed surface from Paper to Polyester sheets. The printing blankets are grouped as :

1) Blankets meant for Sheet fed presses
2) Blankets meant for Web printing
3) Blankets meant for Metal printing and finally
4) Blankets or blanket pasted on rubber rolls for use in continuous printing

The blanket consists of  layers of Fabric, cord ply, layer of compressed rubber again fabric ply followed by  a layer of smooth or rough surfaced rubber coating that acts as receiver of print images for transferring on to another surface.

The Offset Blankets are supplied in different thicknesses, sizes and shore hardness depending on their application to suit the printing machines. Many  blanket manufacturing companies around the world  supply Offset Printing Blankets to suit specific print requirements.  Each firm claim that their product is superior to others.

Therefore the availability of different types of Blankets, their suitability to specific areas and processes, the names and addresses of the manufacturers etc are furnished below to the best extent possible so that it will be of use to the students and others in printing.  The details are derived from the brochures of respective suppliers.
