The metal blocks used in letterpress printing are blocks of wood with a metal plate glued onto them. The metal is engraved by machine or by hand to mirror the letter or effect ultimately required on paper or card.
Once the blocks are finished, they are sorted and fixed to the letterpress machine for printing or embossing. Die-cut blocks are also added to the letterpress machine to cut shapes and effects onto the paper or a card.
A letterpress machine can produce up to 100 impressions per minute. Once all the required sheets are printed, embossed or cut, they are removed from the press. Depending on the type of project, they are then guillotine cut (if necessary) or packaged and sent to the customer.
