Lumicolor inks and varnishes
Lumicolor inks and varnishes are invisible in daylight or, if desired, are visible in a weak pastel shade. Under a UV lamp the printed areas luminesce boldly in blue, yellow and red, or also in other shades. Available for UV flexo printing, they can be used for a many monitoring functions. Under UV light, a colorless code printed on a black background will light up clearly legible.
