FIELD: printing industry.
SUBSTANCE: method is described to manufacture a multilayer substrate comprising the first layer formed from microoptical structures and at least partially covering one or more additional layers, which contain areas of images and/or images of effects that develop optical effect, at the same time microoptical structures are applied by means of deep printing on the layer under the first layer or are introduced into the first layer, at the same time the microoptical structures, as well as areas of images and/or areas of effect are applied with one and the same type form and/or one and the same printing machine in a mutually agreed arrangement. Also a multilayer substrate is proposed, made with the help of such method of treatment, and a protective document comprising a multilayer substrate.
EFFECT: increased reliability of a document.
