Definitions
- the present invention relates to a coated paper comprising at least one pseudo-watermark consisting of a mark giving the said paper a visual effect and a texture resembling that of a watermark.
- the present invention also relates to a method of producing a coated paper according to the invention.
- Watermark papers are generally used in the field of security papers such as means of payment such as banknotes or checks, and official documents such as passports, stamped papers, notarial acts, because the presence of the watermark limits the possibilities of reproduction by photocopying and counterfeiting, and offers a means of recognition and / or authentication of said paper.
- Watermark papers are also used in the field of personalized corporate papers, using the company's logo, name or brand as a watermark.
- the light areas are due to the fact that the thickness of the sheet and the amount of fibers (mass per unit area) is lower in the areas corresponding to indentations in the rest of the paper sheet. Conversely, the dark areas are due to the fact that the thickness of the sheet and the more fibers are more important in the areas corresponding to the footprints.
- 3 - W097 / 17493 has described papers coated with pseudo-watermarks resulting from a variation in the weight of the layer applied in determined zones which induces a variation in thickness and opacity in the said zones where the weight layer is reduced or increased.
- This process involves carrying out the coating using a device comprising a roller, in particular the support roller (bac ing roll), on which recesses are made in relief or in relief which make it possible to control the quantity of layer more or less important depending on the area of the imprint. Regardless of the difficulties possibly linked to its implementation, this process requires a modification of the conventional coating process by using specific rollers specific to each watermark. This process therefore does not offer the flexibility to manufacture small quantities of "custom" paper under economically satisfactory conditions with modern industrial coating machines with large production capacity.
- An object of the present invention is to provide a coated paper comprising pseudo-watermarks consisting of marks which locally modify the physical characteristics of the paper such as its mass volume and therefore certain properties such as its thickness and possibly its opacity.
- Another object of the present invention is to provide a coated paper having pseudo-watermarks consisting of marks which create a contrast in brightness and / or shade with the rest of the sheet of coated paper.
- Another object of the present invention is to provide a coated paper comprising pseudo-watermarks produced without recourse to the application of an ink or a varnish on its surface so that the composition of the paper in the zones constituting the pseudo -filigrane is not significantly modified.
- Another object of the present invention is to provide papers coated with pseudo-watermarks whose usage properties, in particular the printability properties in the areas of the surface of the paper corresponding to said marks, are not significantly altered. compared to blank coated paper.
- Another object of the present invention is to provide a coated paper having pseudo-watermarks which can be produced in variable and low quantities under more economical conditions than by the methods of the prior art and which can be obtained in widths and independent quantities. characteristics of the coating machine, in particular by a method allowing the implementation of modern coating machines with large production capacity without modifying the coating operation proper.
- Another object of the present invention is to provide a coated paper having a pseudo-watermark in which said watermark is produced after the last coating operation, that is to say at the outlet of the coater, possibly on the finished coated paper, c is to say sleeping offline.
- the present invention provides a method of manufacturing a coated paper having at least one mark resembling a watermark, characterized in that said mark is produced after the drying step which follows the last coating operation by carrying out the steps in which: a) applying a rewetting solution to at least one face of the coated paper, in one or more determined area (s) then, b) applying pressure and heat in said area (s) coated paper rewetted so as to evaporate said solution and densify the coated paper in the said zone or zones relative to the rest of the coated paper.
- rewetted coated paper is meant that, in the said at least one zones, the rewetting solution has penetrated inside the layer, possibly inside the support, and has not yet evaporated
- said rewetting solution is evaporated and the coated paper is densified in the areas where said solution has been initially applied.
- Said areas can then present an opacity contrast (reduction of opacity) and / or a brightness contrast (increase in brightness) and / or a color contrast, in particular of color shade (color difference) with the rest of the piece of paper.
- the opacity of the paper is partly linked to the presence of air in the fibrous interstices of the support or the pigment interstices of the layer.
- the solution replaces the air in said interstices.
- the solution is evaporated and the fibers and / or the pigment layer being densified, the air interstices generally occupy a reduced volume and in particular are found in a smaller quantity than initially, which causes de-opacification.
- the densification of the layer and possibly of the support comes from a reduction in thickness of the areas treated compared to the rest of the coated paper, the surface mass and especially the weight of the layer, remaining constant relative to the rest of the paper.
- the contrast of opacity can result from the desopacification of the layer alone, if the rewetting solution does not penetrate into the support and, in addition, from the deopacification of the fibrous support if the quantity and the nature of the rewetting solution and / or the composition of the surface layer allow said solution to penetrate into the support.
- the rewetting of the surface layer facilitates the rearrangement of the pigments during calendering which can create an increase in gloss depending on the quantity and nature of the rewetting solution and according to the characteristics of the layer. In particular, depending on the size and shape of the pigments, these are more or less rearranged during calendering in step b) and the brightness contrast is more or less observable.
- There may be additives in the re-wetting solution and / or in the composition of the layer which facilitate the rearrangement of the pigments and / or which promote the greater or lesser penetration of said solution into the paper.
- the determined rewetting zones define narrow surfaces such as fine lines defining characters or letters
- the brightness contrast under observation in reflected light is difficult to observe by an untrained eye.
- the surface layer is a matt layer comprising pigments of size and shape such that the pigments cannot be rearranged even by calendering, there will be no contrast in brightness in said zones.
- the method of the present invention can also create a change in the color of the paper coated in the said zone or zones when said rewetting solution comprises a coloring agent, in particular a tinting coloring agent.
- the color contrast in the said zone or zones may also result from the modification of the opacity of the surface layer when there is a difference in shade initially between the support and the surface layer and / or between a first layer and a second surface layer because the shade of the finished coated paper is in fact a result of the nuances of the support and of the various layers applied over the support.
- the shade contrast in the said area or areas can only result from the addition of a shading dye additive to the wetting solution.
- the support is less luminous than the layer.
