摘要:
The invention relates to a method for producing a value document, comprising the steps of: a) printing a value document substrate with an oxidatively drying ink; b) treating the printed value document substrate with UV radiation or with ozone; and c) drying the printed valuable document substrate, which has been treated with UV radiation, at room temperature or at an elevated temperature.
摘要:
An ink curing apparatus (11) comprising a UV light source (13); at least one moveable shutter means (17, 17a), which is moveable about the longitudinal axis of the UV light source (13); and at least one reflector (15); wherein at least one air passage (19a) is defined along substantially the entire surface area of the or each reflector (15).
摘要:
An LED-UV lamp that is easily interchangeable within a UV-curing process and scalable in length with a fine resolution so that it is easily customizable to any UV-curing application. The LED-UV lamp may incorporate multiple rows of LEDs and contain corresponding optics that effectively deliver radiant power to a substrate at distances of several inches.
