The MORNING STAR and MORNING STAR-254 colorless inks are used with a soft tip pen.
These inks contain a special luminescent marker.
It allows making marks on documents, invisible under normal light.
Marks made with the MORNING STAR ink can be detected due to bright blue luminescence under ultraviolet light with the wavelength of 365 nm, the MORNING STAR-254 - red or green luminescence under ultraviolet light with the wavelength of 254 nm.
The BLUE STAR (blue ink) and the BLACK STAR (black ink) special inks for fountain pens allow authenticating writings, made by these inks.
These inks contain luminescent substance with "concentrated quenching" effect.
They cannot be detected under normal or ultraviolet light.
Marker presence can be found only on writing imprint, made with slightly wet paper cloth.
Luminescence appears when imprint is placed under ultraviolet light with the wavelength of 365 nm.
LUMINESCENT STAMP-PAD INKS
The STAMP color stamp-pad ink, also the STAMP-B and the STAMP-B-254 colorless stamp-pad inks are used for protection of documents against forgery or substitution.
Inks contain special marker not visible under normal light.
Marker's presence can be detected due to typical luminescence of the stamp imprint under ultraviolet light with the wavelength of 365 nm (254 nm UV light for the STAMP-B-254 ink).
Special clean ink-pad is used for applying stamp ink.
The STAMP-980 stamp-pad ink, offered as a ready-to-use ink-pad, is used for protection of sensitive documents against forgery or substitution.
Marker can be detected due to luminescence under infrared light with the wavelength of 980 nm.
