Definitions

  • the present invention relates to high-quality-printable watermarked paper materials.
  • a high-quality-printable watermarked paper having a first surface impressed with a watermark of predetermined pattern; and a second surface opposite said first surface and which is substantially flat; said watermarked paper being characterized by being of a substance ranging between 70 and 200 g/m 2 ; and in that said watermark is of a marking depth of over approximately 10% of the thickness of said watermarked paper.
  • the watermark is of a marking depth ranging between approximately 10% and approximately 30% of the total thickness of the watermarked paper, and the watermarked paper is of a thickness ranging between approximately 0.05 mm and approximately 1 m, and preferably ranging between approximately 0.1 mm and approximately 0.5 mm.
  • the substantially flat second surface of the watermarked paper, opposite the first surface impressed with the watermark has a coating.
  • the invention therefore also relates to a watermarked, coated paper material in sheet form, permitting high-quality print, and comprising a base paper having a first surface impressed with a watermark, and a substantially flat second surface having a coating; the paper material being characterized in that said base paper, without said coating, is of a substance ranging between 70 and 200 g/m 2 ; and in that said watermark is of a marking depth of over approximately 10% of the thickness of said base paper, and preferably ranging between approximately 10% and approximately 30% of the thickness of said base paper.
  • a watermarked paper which is not only impressed with the watermark on only one surface - while the opposite surface is substantially flat, may therefore be coated, and permits high-quality print - but which at the same time is much lighter (for a given thickness) than currently available types of paper, and has a clearer, better impressed watermark.
  • the watermarked paper according to the invention has, for a given thickness, a much lower substance and is therefore much lighter.
  • Known types of paper (obtained by calendering) of the same thickness as the watermarked paper according to the invention have a much higher substance, and the depth of the watermark, as a result in fact of the calendering process, is normally less than 10% of the total thickness of the paper (and therefore poorly defined and totally unsatisfactory for most applications).
  • a watermarked paper 1 permitting high-quality print, has two opposite, parallel, facing surfaces 2 and 3; surface 2 is impressed with a watermark 4 of predetermined pattern or design and shown schematically by a number of incisions or depressions 5 impressed on surface 2 and defining the markings; while surface 3 is substantially flat and has no marking, as can be seen when held up to grazing light.
  • Watermarked paper 1 has a substance ranging between 70 and 200 g/m 2 , and may vary in thickness S1 (depending also on the composition of the watermarked paper): purely by way of example, watermarked paper has been produced with the above substance and ranging in thickness S1 between 0.05 and 1 mm (50-1000 ⁇ m). The preferred thickness S1 ranges between 0.1 and 0.5 mm (100-500 ⁇ m).
  • watermark 4 is of a marking depth S2 - defined as the depth of incisions or depressions 5 (i.e. of the markings) - of over approximately 10% of thickness S1 of watermarked paper 1.
  • the watermark is at least 10 ⁇ m deep, so that, at the markings, the thickness of the watermarked paper is reduced to 90 ⁇ m.
  • marking depth S2 ranges between approximately 10% and approximately 30% of thickness S1.
  • Substantially flat surface 3 is a coated surface, i.e. having a coating 6 of any known type. Since surface 3 has no markings, coating 6 may be applied easily and is in turn substantially flat, homogeneous, and uniform, thus permitting high-quality print using any known printing process.
  • Watermarked paper 1 thus constitutes a base paper from which to obtain, when coated, a watermarked, coated paper material 10 in sheet form permitting high-quality print and characterized by the presence of base paper 1 described above.
  • Watermarked paper 1 and paper material 10 can be produced using substantially known methods, but with certain provisions by which to impart to the watermarked paper and paper material the surprising characteristics described and claimed herein. More specifically, and as shown schematically in Figure 3, a web 11 of paper, produced in conventional manner and supported on a canvas belt 12, is fed to a watermarking unit 13 comprising a marking roller 14 bearing the watermark pattern to be impressed on the paper; a water tank 15 underneath marking roller 14; and two supporting rollers 16. Marking roller 14 exerts a predetermined pressure on the top surface of web 11, at a contact line 17; and the two supporting rollers 16 are located beneath canvas belt 12, inside water tank 15 and on opposite sides of contact line 17.
  • a watermarked paper has surprisingly been obtained having markings only on one surface, while the opposite surface remains substantially flat.
  • the flat surface of the watermarked paper is coated using any known method, and then printed using any known printing process.
