Scratch Off
Scratch off inks are high opacity security printing inks used to conceal underlying data or messages. These products are formulated to provide clean and easy removal with a fingernail or coin. They are used in the printing of instant lottery tickets, commercial games (in magazine inserts, for example), and direct mail, for amusement and promotional purposes.
UV Scratch Off inks are durable and flexible. These properties can be extremely influenced by the printing conditions such as ink film thickness, printing speed and efficiency of the UV lamps.
