Abstract
There is described a combined printing press () for the production of security documents, in particular banknotes, comprising a screen printing group () and a numbering group () adapted to process printed substrates in the form of individual sheets or successive portions of a continuous web. The screen printing group () is located upstream of the numbering group () and comprises at least one screen printing unit (-) designed to print a pattern of optically-variable ink, which optically-variable ink contains flakes that can be oriented by means of a magnetic field. The screen printing group further comprises a magnetic unit () located downstream of the screen printing unit (-), which magnetic unit () is designed to magnetically induce an optically-variable effect in the pattern of optically-variable ink applied by the screen printing unit (-) prior to drying/curing of the optically-variable ink. The screen printing group () further comprises at least one drying/curing unit () designed to dry/cure the pattern of optically-variable ink in which the optically-variable effect has been induced by the magnetic unit (), prior to transfer of the printed substrates to the numbering group ().
