Abstract
Przedmiotem zgłoszenia jest sposób drukowania cyfrowego dokumentów zabezpieczonych oraz wydrukowany cyfrowo dokument zabezpieczony. Sposób drukowania cyfrowego dokumentów zabezpieczonych wielobarwnych, w którym na podłożu drukowym za pomocą maszyny drukującej drukuje się obrazy rastra poszczególnych kanałów barwnych wraz z oznaczeniem zabezpieczającym, znamienny tym, że: ustala się lokalizację oznaczenia zabezpieczającego (12) w pierwszym kanale barwnym, przy czym barwa pierwszego kanału barwnego w przestrzeni CIELab ma jasność (L) o wartości większej od 80, co najmniej jeden ze współczynników a lub b o wartości w zakresie od -128 do -80 albo od 80 do 127, oraz wskaźnik fluorescencji (dFL) o wartości nie większej niż 1; generuje się identyfikator lokalizacji (13) w postaci kodu matrycowego zawierającego zakodowane informacje o ustalonej lokalizacji oznaczenia zabezpieczającego (12); ustala się położenie identyfikatora lokalizacji w drugim kanale barwnym, innym niż pierwszy kanał barwny; oraz generuje się obrazy rastra dla dokumentu zabezpieczonego poprzez dodanie do podstawowych obrazów rastra, dla podstawowego obrazu wielotonalnego, stanowiącego główną treść dokumentu, oznaczenia zabezpieczającego (12) w pierwszym kanale barwnym oraz identyfikatora lokalizacji (13) w drugim kanale barwnym.The subject of the application is a method of digital printing of security documents and a digitally printed security document. A method of digital printing of multi-color security documents, in which raster images of individual color channels together with a security marking are printed on a printing substrate by means of a printing machine, characterized in that: the location of the security marking (12) is determined in the first color channel, wherein the color of the first color channel in the CIELab space has a lightness (L) of greater than 80, at least one of the coefficients a or b with a value in the range from -128 to -80 or from 80 to 127, and a fluorescence index (dFL) of no greater than 1; a location identifier (13) is generated in the form of a matrix code containing encoded information on the determined location of the security marking (12); the position of the location identifier is determined in the second color channel, other than the first color channel; and generating raster images for the security document by adding to the basic raster images, for the basic multi-tone image constituting the main content of the document, a security mark (12) in a first color channel and a location identifier (13) in a second color channel.
