An inkjet ink set consisting of a black inkjet ink, a cyan inkjet ink and two inkjet inks A and B, optionally complemented by a white ink and/or a colourless ink, wherein the inkjet ink A has a hue angle H* between 70 and 85 and a chroma C* between 30 and 80; the inkjet ink B has a hue angle H* between 20 and 40 and a chroma C* between 30 and 80; and the CIE L* a* b* coordinates were determined on polyethylene coated white paper for a 2&#xb0; observer under a D50 light source.

Inkjet printing of wood colours

A method of producing a 2D barcode on an article including a laser markable layer, wherein the 2D barcode includes a primary information pattern representing primary information, which can be read by a 2D-barcode-reader, and a secondary information pattern embedded within the 2D barcode, which is difficult to reproduce without alteration, includes a laser marking step of exposing the laser markable layer with an infrared laser thereby forming the secondary information pattern of the 2D barcode.

Authentication method of a two dimensional bar code

A security article includes a laser markable layer and a transparent outer layer or sheet having lenticular lenses on its outer surface, both provided, in this order, on an opaque core support, characterized in that the laser markable layer has a dry layer thickness of less than 50 &#x3bc;m. An improved contrast is obtained between interlaced images exposed into the security article of the invention.
