STAMP MANUFACTURER THROUGH DIRECT

PRINTING TECHNOLOGY - MASS PRODUCTION

The Direct Imaging Press is based on a typical ‘offset press except that it is computer controlled. All the imaging plates are pressed onto the paper/card precisely through the control of a computer system. Usually an offset press operates using one imaging plate at a time. This means that the paper / card has to be sent through the offset press at least four times until the application of colour is complete. With the Direct Imaging Press the card / paper is sent through once.

The entire operation, including quality control is computer controlled. Direct Imaging Presses are very fast and suitable for the manufacture of high numbers of stamps. This form of printing is suitable for Batch Production and Continuous Production, where high volumes of prints are required.

Some Direct Imaging Presses use five colour ink rollers. The first four apply the graphics whilst the fifth ink roller applies the text. In the case of postage stamp manufacture, this is used to apply self adhesive.

Direct imaging presses are not as economical as digital copiers, digital desktop printers, and digital presses which can be used for small print runs. They are, however, more economical than digital presses or desktop printers for producing large press runs of static documents due to the higher printing speed they are able to attain.

 
 
   

Direct Printing uses technology called CMYK colour - known also as four-colour printing, full-colour printing, or process colour printing. Cyan, magenta, yellow, and black inks are printed on the paper as small dots. This process is used when printing the full range of colour is required, such as photography or stamps.

   

When the stamps have been printed they are sent for UV Varnishing. When dry this gives a gloss finish and helps protect the printing underneath.
