Abstract
The invention relates to a carrier representing value provided with recognizable pattern, for instance in the form of giro checks, bankchecks, banknotes, shares, bonds and other documents representing a value, wherein the patterns are formed by parts treated by means of a laser beam. This object is reached in that the patterns have been provided by means of a laser light beam. The use of a laser beam makes it possible to apply particularly fine structures which either cannot be applied with other treating methods, or only with the greatest financial effort. The use of laser beams enables variation of the width or depth of the channels or perforations which is almost impossible with other treating methods.
