An article (10) useful as a substrate for security printing comprising a pre- cut facestock capable of being printed, a pressure sensitive adhesive (12) having a first and second surface, and a release liner, (13) wherein the first surface of the pressure sensitive adhesive is bonded to the facestock (11) and the second surface is releasably bonded to the release liner, and wherein the bond strength of the releasable bond between the pressure sensitive adhesive and the release liner is greater than the temporary bonds formed with an ink and the printable surface of the facestock. The articles and methods of the present invention involve articles useful as facestocks for security printing. In one embodiment, the invention relates to the preparation and printing of stamps. An advantage of the present articles and methods is the use of articles with a pressure sensitive adhesive and a release layer, which do not lift off during printing. The bond strength of the releasable layer is greater than the temporary bonds formed with the ink and ink applicator during printing.
L'invention concerne un type d'article utile comme substrat pour les impressions contrôlées, qui comprend une pellicule frontale prédécoupée susceptible d'être imprimée, un adhésif autocollant ayant des première et seconde surfaces, et une doublure décollable. La première surface de l'adhésif autocollant adhère à la pellicule en question, et la seconde surface adhère de manière libérable à la doublure décollable. La résistance d'adhésion de la liaison libérable entre l'adhésif autocollant et la doublure considérée est supérieure à la force des liaisons temporaires résultant de l'application d'une encre à la surface imprimable de la pellicule frontale. Les articles et les procédés considérés englobent certains articles utiles en tant que pellicules frontales pour les impressions contrôlées. Un aspect de l'invention se rapporte à la préparation et à l'impression de timbres. Un avantage des articles et procédés considérés réside dans l'utilisation d'articles comportant un adhésif autocollant et une couche qui se décolle, sans décollement durant l'impression. La résistance d'adhésion de la couche qui se décolle est supérieure à la force des liaisons temporaires résultant de l'encre et du mécanisme d'application de l'encre en cours d'impression.
