Abstract
A method of in-register exposing and printing of a flexible letterpress form for spot varnishing, which comprises fixing on a copying cylinder in-register a flexible letterpress form having a register system in a region of the leading edge of the form, and exposing the form, then clamping the flexible letterpress form on a rubber-blanket cylinder having a greater diameter than that of the copying cylinder so as to compensate for distortion of a subject in circumferential direction during circular exposure.
