- Another object of the present invention is to provide a coated paper having pseudo-watermarks which can be produced in variable and small quantities under conditions more economical than by the processes of the prior art and which can be obtained by widths and quantities independent of the characteristics of the coating machine, in particular by a process allowing the implementation of modern coating machines high production capacity without modifying the actual coating operation.
- 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, i.e. at the output of the coater, possibly on the finished coated paper, i.e. off-line sleeping.
- said rewetting solution is evaporated and the coated paper is densified in the areas where said solution was initially applied.
- Said zones can then have an opacity contrast (reduction opacity) and / or a contrast of brightness (increase in brightness) and / or a contrast of color especially shade of color (color difference) with the rest of the sheet paper.
- the opacity of the paper is partly linked to the presence of air in the fibrous interstices of the support or 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 gaps occupy overall a reduced volume and in particular are found in lower quantity that initially, which generates a de-opacification.
- the densification of the layer and possibly of the support comes from a reduction thickness of the treated areas compared to the rest of the coated paper, the basis weight and especially the weight of the layer, remaining constant relative to the rest of the paper.
- the surface mass is less in the areas clear because the fibers deposited are in smaller quantity compared to the rest of the sheet.
- the surface mass is not constant because the weight of the layer is reduced in certain areas.
- the contrast of opacity can result from the de-opacification of the layer alone, if the rewetting solution does not penetrate into the support and, in addition, the desopacificaton of the fibrous support if the quantity and nature of the re-wetting solution and / or the composition of the surface layer allow said solution to penetrate 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 the shape of the pigments these are more or less rearranged during calendering in step b) and the brightness contrast is more or less observable.
- the determined rewetting zones define surfaces narrow such as fine lines defining characters or letters, the contrast of brightness in observation under reflected light is difficult to observe by an untrained eye.
- the surface layer is a mat layer comprising size and shape pigments such as pigments cannot be rearranged even by calendering, no brightness contrast will be observed in said areas.
- the method of the present invention can also create a modification of the color of the coated paper in said area (s) when said rewetting solution comprises a coloring agent, in particular a tinting coloring agent.
- the contrast of color 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 layer surface and / or between a first layer and a second surface layer because the nuance finished coated paper is actually a result of the nuances of the support and the different layers applied over the support.
- the support and the layer have the same nuance, the contrast of nuance in the said zone or zones can only result from the addition of a shading additive in the fountain solution.

Description
Pour réaliser des papiers couchés filigranés, ces procédés de filigranage en partie humide ne sont pas adaptés pour plusieurs raisons. Tout d'abord, lorsque le filigrane est réalisé sur le papier support, la différence d'épaisseur et la différence d'opacité de la feuille dans la zone du filigrane réalisé sur le papier support, sont altérées voire supprimées par le dépôt de la couche qui uniformise et opacifie la surface du support. D'autre part, les procédés de filigranage en partie humide impliquent des moyens de réalisation onéreux spécifiques pour chaque type de filigrane tels que les rouleaux filigraneurs. Et, comme les machines de couchage moderne ont des capacités de production très importantes, ils n'offrent donc pas la souplesse nécessaire pour fabriquer les papiers couchés filigranés en petites quantités que le marché attend.
Indépendamment des difficultés éventuellement liées à sa mise en oeuvre, ce procédé nécessite une modification du procédé de couchage classique en utilisant des rouleaux spécifiques et particuliers à chaque filigrane. Ce procédé n'offre donc pas la souplesse permettant de fabriquer de petites quantités de papier « sur mesure » dans des conditions économiquement satisfaisantes avec des machines de couchage industrielles modernes à grande capacité de production.
Les papiers aussitôt remouillés sont passés dans une calandre de laboratoire à deux rouleaux chauffés à 50°C, sous une pression linéaire de 1,9 kN/cm.
Le papier aussitôt remouillé est passé dans une calandre de laboratoire (différente de celle des conditions A et B) les deux rouleaux chauffés à 50°C, sous une pression linéaire de 3.0 kN/cm.
- En figure 4a : par vision directe sous forme de contraste de nuance (zones remouillées devenues moins lumineuses)
- En figure 4b : par observation en lumière transmise sous forme de contraste d'opacité (zones remouillées devenues moins opaques et donc plus claires),
