The ulti­mate Adana flatbed” is how Bob Richard­son describes the Adana QH (which is also referred to as the Adana HQ). The machine is capa­ble of a large print­ing area (9.75″ x 7.25″) but speed of out­put is slow. This dis­suad­ed the job­bing print­er from using this machine; but it was tak­en up by art col­leges and those wish­ing to exper­i­ment. John Ryder’s ‘Print­ing for Plea­sure’ makes a great case for the QH — the flat bed allows sim­pler lock­ing-up; and for ink­ing to be car­ried out selec­tive­ly. There are many who con­sid­er the ink­ing mech­a­nism inad­e­quate and remove the arms to allow hand-ink­ing by roller.

The Adana series of flatbed machines began in 1922, and the QH was the last in that series. The imme­di­ate pre­de­ces­sor of the QH was the ‘QFB-1945’. The QH ini­tial­ly came out in 1949 with­out an ink­ing disc, and a sin­gle, large roller. By 1957 this was phased out in favour of a rotat­ing ink disc and two small­er rollers. Adana dis­con­tin­ued the machine in 1985.

The QH has a num­ber of refine­ments: there screw in the back of the plat­en pre­vents too much force being applied to the forme; and an eccen­tric rod at the hinged end allows for adjust­ment to cre­ate a lev­el print­ing sur­face. The press is com­mon­ly called the Adana HQ, but the fir­m’s cat­a­logues state that the machine is called the ‘Adana QH’.

These machines are more sought-after and appear on the mar­ket less fre­quent­ly than Adana’s ver­ti­cal plat­en machines.
