Title (EN) COATED PAPER FOR SHEET-FED OFFSET PRINTING
(FR) PAPIER REVETU POUR L'IMPRESSION OFFSET A FEUILLES
Abstract:
(EN) The specification pertains to a single or multiple coated printing sheet in particular but not exclusively for sheet-fed offset printing with an image receptive coating layer on a paper substrate. The printing sheet has the property that it can be printed in an offset printing process without spraying a fine powder, usually called offset powder or dust powder, on the sheet as it comes off the press to prevent the ink from transferring to the back side of the next sheet. Also irradiative (UV or IR) drying on the sheet fed press is not necessary and/or the use of overprint varnish is not required. In addition to that, unexpectedly short times until reprinting and converting can be achieved. Furthermore methods for making such a printing sheet and uses of such a printing sheet are disclosed.
(FR) L'invention concerne une feuille d'impression revêtue simple ou multiple destinée particulièrement, mais pas exclusivement, à l'impression offset à feuilles, et comprenant une couche de revêtement réceptrice d'image sur un substrat de papier. Cette feuille d'impression se caractérise en ce qu'elle peut être imprimée au moyen d'une opération d'impression offset sans pulvérisation d'une poudre fine, habituellement appelée poudre offset ou poudre poussière, sur la feuille lorsqu'elle sort de la presse, ce qui permet d'empêcher un transfert de l'encre vers la face arrière de la feuille suivante. En outre, un séchage par rayonnement (UV ou IR) sur la presse à feuilles n'est pas nécessaire et/ou l'utilisation d'un vernis à surimpression n'est pas requise. De plus, des temps jusqu'à réimpression et des temps de conversion étonnamment courts peuvent être obtenus. L'invention concerne également des procédés de fabrication de cette feuille d'impression ainsi que les utilisations de cette feuille d'impression.
