A method of printing a patterned layer comprises (step 31 in FIG. 4 ) detecting the position and alignment of clichés supported on subbeds on the bed of a printing machine (see FIG. 5 ) using alignment marks thereon. The positions of the subbeds are adjusted according to the detected alignment and position of the areas of the mother glass and the positions and alignment of the clichés (step 32 in FIG. 4 ). The clichés are then inked (step 33 in FIG. 4 ). Alternatively, steps 32 and 33 could be reversed. Ink is transferred (step 34 in FIG. 4 ) from the clichés, supported on the printer subbeds, onto a blanket 16 (see FIG. 2 (b)). The material on the blanket 16 is transferred (step 35, FIG. 4 ) onto the mother glass (as in FIG. 2 (c)). A novel printing machine bed ( 41, FIG. 5 ) comprises an array of subbeds ( 42 - 45 in FIG. 5 ) individually alignable in a common plane. |
