Movable type, consisting of reusable, individual letters, was developed by Bi Sheng (970 to 1051, approximately), of Hubei, China. Much later, letterpress printing would become a thriving industry in Hong Kong, which manufactured and exported movable type. Now all the tools, machinery and more than 170,000 lead type printing blocks are on display in an open-plan studio in Yau Ma Tei. Inspect old metal type stacked neatly in wooden cases, organised according to frequency of use; join workshops to experience the art of typesetting from layout to print – and take the results home; and absorb the story of the Open Press mission to recast ‘Hong Kong Type’.
