The present invention relates to a sheet material () comprising at least one first layer defining an outer surface of the sheet material and having at least one first color, at least one second layer comprising at least one watermark () and having at least one second color, the first and second colors having at least different saturations and/or hue angles.

Sheet material comprising at least one watermark having a colored shade

The present invention relates to the field of paper and relates to a sheet including a high-definition high-contrast multitone watermark having areas of pronounced brightness. Such watermark is particularly obtained by means of a part () including a surface () having a raised area and perforations (). The perforations () are such that making the cross-section thereof, at a given distance from the draining surface, directly depends on said distance. The present invention also relates to the method for manufacturing said part that is used for forming one such watermark, to the part itself, and to the use of said part when forming a watermark.

Device for creating multitone watermarks and methods of manufacture and use thereof

The invention relates to a method for securing a colored or uncoloured translucent or opaque object (), in which a sticker () is affixed to the back of the object (), said sticker comprising: a substrate including a watermark or pseudo-watermark () which is sufficiently transparent to allow the object () to be seen through the watermark or pseudo-watermark (); and a luminescent agent which is positioned at least partially over the watermark or pseudo-watermark () between the watermark or pseudo-watermark () and the object ().

Method for securing a coloured opaque object

A security paper comprising a fibrous substrate comprising a watermark having repeating motifs, and a security structure that does not completely cover the watermark and has at least one semi-reflective area which is superposed at least partly on the watermark; which paper on the one hand allows observation, through the semi-reflective area, at least partially, of one of the motifs, and on the other hand allows observation at least partially of another of said motifs in a region of the watermark that is not covered by the security structure.

Security paper

The present invention relates to a sheet material comprising at least one first layer defining an outer surface of the sheet material and having at least one first color, at least one second layer comprising at least one watermark and having at least one second color, the first and second colors having at least different saturations and/or hue angles.

The present invention relates to a security document and/or document of value comprising:
