Crosfield Electronics

From Graces Guide

of Hemel Hempstead

Crosfield Electronics was founded by John Crosfield (1915-2012) to produce process imaging devices for the printing industry. The firm was notable for its innovation.[1]

1955 Collaboration with James Halley and Sons, developing improved tools for control of printing process

Developed a synchroscope which removed the speed limitation imposed by the fact that a press could run only as fast as the operator's eye could check the printed web as it moved through the machine - and that was not very fast. The synchroscope produced a stationary image of the moving web, allowing the printer to check every detail on a web moving far faster than the eye could follow.

Other Crosfield products used regularly on Halley presses were automatic controls for colour register and for electronic ink viscosity.

1979 Introduced the Computervision Designer IV system

1981 April. Introduced a new design of electronic colour scanner. They also invested £2 million pounds into a new CNC machine shop with tapes produced direct from the design database.

1981 June. Developing the CAD-System. Crosfield's Magnascan 530/540 was the latest in the series of machines which provided electronic colour separation from colour transparencies and prints, enhancing them for consistent quality when reproduced in magazines and brochures etc.[2]

By 1986 was the printing machinery subsidiary of De La Rue

1987 Awarded the 1986 Natwest Engineering Marketing Award[3]
