Abstract
A substrate with security print and a method to obtain it, which comprises a laminar substrate where color ink prints have been applied on the obverse and reverse of the substrate, whereby these prints coincide and leave an area free of print to form a watermark, and an ultraviolet ink print within said watermark, in a way that the substrate can be verified by holding it against the light to visually verify the watermark and under ultraviolet light to visually detect the ultraviolet ink print that coincides with the watermark.
Claims14
A substrate with security print, of the type containing at least a layer of ink that defines a watermark, comprising:
- a laminar substrate,
- a print with color ink to the obverse side of the substrate and a print with color ink on the reverse side of the substrate, said prints coinciding and being in agreement with a printing pattern which leaves at least an area free of print, forming said watermark, and
- an ultraviolet ink print within said area that forms the watermark, on the obverse and reverse sides of said laminar substrate.
A method to obtain a substrate with security print, the method comprising:
- providing a laminar substrate,
- applying a print with color ink to an obverse side of the substrate and a print with color ink on a reverse side of the substrate, said prints coinciding and being in agreement with a printing pattern which leaves at least an area free of print, forming a watermark, and
- applying an ultraviolet ink print within said area that forms the watermark, on the obverse and reverse sides of said laminar substrate.
