During the 1980s, after several years in other industries, Robert was joined by his sons Richard and Clifford Burt, who continue to run the company today. The sales of paper for commercial printing and publishing developed greatly in the 1970s and 1980s, and R. K. Burt & Company continue to provide a comprehensive stock management service to publishers for these papers which are delivered direct from paper mills to printers throughout the country.

However, in the 1960s R. K. Burt & Co. became London agents for Barcham Green who produced hand-made papers. Almost as a separate division, the company became the largest wholesale paper merchant in the U.K. specialising in very high quality paper for every type of use for artists, including printmaking.
