A method of producing a succession of self-adhesive labels (6) carried on a backing of release material (8), the method comprising the steps of: (a) providing a first web of release material carrying a succession of folded leaflets (30); (b) conveying the first web along a pathway by a web conveyor; (c) printing a second web (36) with a succession of images along its length by at least one print station (44, 46, 48, 50), the or each print station being driven independently of the web conveyor and being directly or indirectly registered with reference to the first web or the folded leaflets; (d) laminating the printed second web over the succession of folded leaflets; and (e) die-cutting (54, 56) through at least the second web as far as the release material to form a succession of self-adhesive labels. The invention also provides an apparatus for producing a succession of self-adhesive labels carried on a backing of release material in which a control system is provided for registering the at least one print station.
