Abstract
Register marking units consist of a base carrier, usually in strip form, having successive ink areas printed on it which are printed in a shearable ink and which are in turn overprinted by a suitable pattern, the pattern being printed in adhesive. The pattern may be adhered to an upper transparent sheet and the ink area to a lower sheet e.g. by adhering the base carrier thereto via a layer of pressure sensitive adhesive on the side of the base carrier remote from the ink areas and normally protected by a release paper. The upper and lower sheets may act to sandwich the unit, to leave the adhesive pattern adhered to the upper sheet when the upper and lower sheets are separated. Thereafter said upper and lower sheets may be re-aligned by registering the adhesive pattern with the holes in the ink area from which ink was removed by the adhesive when upper and lower sheets were separated.
