组合式印刷机
摘要：
本文描述了用于安全文件(尤其是钞票)的生产的组合式印刷机(10；10*)，该组合式印刷机包括丝网印刷组(2；2*)和凹版印刷组(3)，该丝网印刷组和凹版印刷组被适配成用于处理单张纸形式或连续卷筒纸的连续部分形式的承印物。该丝网印刷组(2；2*)定位在该凹版印刷组(3)的上游并且包括至少一个丝网印刷单元(20；20*)，该至少一个丝网印刷单元被设计成用于将光变油墨图案印刷到这些承印物的一面上，该光变油墨包含可以通过磁场被定向的碎片。该丝网印刷组(2；2*)进一步包括定位在该丝网印刷单元(20；20*)下游的磁性单元(24；24*)，该磁性单元被设计成用于在该丝网印刷单元(20；20*)所敷印的光变油墨图案中磁性地引起光变效应。该丝网印刷组(2；2*)进一步包括至少一个干燥/固化单元(25，28；25*，28*)，该至少一个干燥/固化单元被设计成用于在承印物被传递至该凹版印刷组(3)之前干燥/固化该磁性单元(24)已经在其中引起了光变效应的光变油墨图案。
摘要（英）：

There is described a combined printing press (10; 10*) for the production of security documents, in particular banknotes, comprising a screen printing group (2; 2*) and an intaglio printing group (3) adapted to process substrates in the form of individual sheets or successive portions of a continuous web. The screen printing group (2; 2*) is located upstream of the intaglio printing group (3) and comprises at least one screen printing unit (20; 20*) designed to print a pattern of optically-variable ink onto one side of the substrates, which optically-variable ink contains flakes that can be oriented by means of a magnetic field. The screen printing group (2; 2*) further comprises a magnetic unit (24; 24*) located downstream of the screen printing unit (20; 20*), 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 (20; 20*). The screen printing group (2; 2*) further comprises at least one drying/curing unit (25, 28; 25*, 28*) designed to dry/cure the pattern of optically-variable ink in which the optically-variable effect has been induced by the magnetic unit (24), prior to transfer of the substrates to the intaglio printing group (3).
