The business carried on for many years under the control of Arthur Castle, eldest son of the founder, supplying all types of printing to local businesses and individuals, and it was during his time at the helm that litho printing from pre-sensitised plates started to replace the traditional method of printing from moveable type and later hot metal produced for Linotype composing machines. Litho printing took over completely in the late sixties and by the time that the firm had outgrown the old building and moved to a purpose built factory in Rayleigh, the switch to Litho was complete.
