Patent number: 8101250Abstract: 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. Unexpectedly short converting times and times until reprinting can be achieved by choosing a coating, in which the image receptive coating layer comprises a top layer and/or at least one second layer below said top layer, said top and/or second layer comprising a pigment part, wherein this pigment part is composed of 1-95 preferably of 80-95 parts in dry weight of a fine particulate carbonate and/or of a fine particulate kaolin or clay and 1-100, preferably 6 to 25 parts in dry weight of a fine particulate silica, and a binder part, wherein this binder part is composed of 5-20 parts in dry weight of binder and less than 4 parts in dry weight of additives. Furthermore methods for making such a printing sheet and uses of such a printing sheet are disclosed.Type: GrantFiled: July 12, 2006Date of Patent: January 24, 2012Assignee: Sappi Netherlands Services B.V.Inventors: Jean-Pierre Haenen, Peter Resch, Bert Scholte

Publication number: 20110083573Abstract: Coating for an offset paper comprising a catalyst for fixing polymerisable or crosslinkable constituents of the offset ink. The chemical drying time can be substantially reduced if such a catalyst system is added to the coating, wherein preferentially such a catalyst is a transition metal complex/salt, like Mn (2-ethylhexanoate, bpy).Type: ApplicationFiled: October 1, 2010Publication date: April 14, 2011Applicant: SAPPI NETHERLANDS SERVICES B.V.Inventors: Bert SCHOLTE, Jean-Pierre HAENEN, Elisabeth BOUWMAN, Zhiliang LIU

Publication number: 20080261021Abstract: 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.Type: ApplicationFiled: July 12, 2006Publication date: October 23, 2008Applicant: SAPPI NETHERLANDS SERVICES B.V.Inventors: Jean-Pierre Haenen, Peter Resch, Bert Scholte

Patent number: 6899921Abstract: A method for reducing back trap mottle of coated paper, comprising adjusting the absorbency of the coated surface combined with adjusting the adhesion between the coated paper surface and the ink. Polar additives are used in the paper coating to increase the polar fraction of the surface energy. The coated paper has a reduced sensitivity to back trap mottle.Type: GrantFiled: January 29, 2001Date of Patent: May 31, 2005Assignee: Sappi Maastricht B.V.Inventors: Jean Pierre Haenen, Maurice Essers
