Invisible ink reveals new uses for Indigo presses
If the inclusion of ultra niche markets into a technology’s portfolio of “can-do” attributes is anything to go by, then perhaps we should see digital color printing in a more comprehensive light. It appears that owners of certain HP Indigo six-color presses (1000, s2000 and ws2000 models) can now buy invisible inks as part of the company’s security package. Within this esoteric area of short-run printing, the invisible ink can only be seen by using an ultra violet lamp, causing the ink to fluoresce to a bright red color. As usual with this type of “security solution,” it works best when combined with other covert or overt security features, such as alphanumeric codes.
HP says that bar codes can be optimized to contain large amounts of data, and can be printed with invisible ink to eliminate unwanted graphic elements while increasing overall security.
“Forgery and counterfeiting are becoming increasingly important to business professionals,” said Rafi Maor, HP vice president and general manager, Indigo Division. “By combining variable data printing technology with HP’s invisible ink, digital printing can help take security to a new level.”
