A process for high pressure embossing a single ply of paper and the paper produced thereby. The embossing process requires two rolls, a pattern roll (30) and an anvil roll (32). The rolls are loaded together at a pressure of at least 1000 psi at the nip. A single ply of paper is embossed in the nip. The embossments of the paper do not extend outwardly beyond the thickness of the paper to have any out of-plane deformation. The embossments are typically glassined. The resulting paper has an aesthetically pleasing appearance, without undue loss of tensile strength from the embossing process.
Procédé permettant de gaufrer à haute pression une bande simple de papier, et papier ainsi produit. Le procédé de gaufrage nécessite deux cylindres, un cylindre à motif (30) et un cylindre enclume (32). Les cylindres sont chargés ensemble à une pression d'au moins 1000 psi au niveau de la pince. Une bande unique de papier est gaufrée dans cette dernière. Les zones gaufrées du papier, qui ne dépassent pas, vers l'extérieur, l'épaisseur du papier, et n'entraînent donc pas de déformation hors plan, ont typiquement une apparence lisse. Le papier obtenu a un aspect agréable sur le plan esthétique, sans perte inutile de la résistance à la tension due au processus de gaufrage.
