After the War there was an increase in demand for multiple-image printing
After the War there was an increase in demand for multiple-image printing, stimulated by the needs of the packaging industry for labels and decorative wrappers and boards. One of the most successful models was the Repetex, manufactured by Typefoundry Amsterdam and sold in the UK through Sidney R Littlejohn & Co, Ltd. The Repetex was designed to repeat an image from a negative or positive on to any flat material that can be made photosensitive, whether zinc, aluminium, brass, copper or steel or photographic plates or film, and was there fore suitable for direct printing on photolitho plates, or preparation of multiple image negatives for subsequent preparation of letterpress, litho or gravure surfaces. A point of particular importance was that as the original positive or negative could be registered with great precision, colour sets could be produced with ease and accuracy. Most printing-down machines required mechanical pressure to give proper contact between negative and plate. The Repetex, on the other hand, was provided with an automatic vacuum system that could be varied to give the appropriate pressure according to the thickness of the plate, and could guarantee hairline reproduction form fine line and halftone, and that gave uniform contact pressure over the whole area. The Repetex was a large machine. It needed a great deal of floor space and weighed 4,4500 pounds. It could take plates of sizes up to 5’ 11” x 6’ 5” which made it the largest of it kind available in the UK.
