IR Blocking Inks

Description

H. W. Sands’ series of IR Blocking Screen Printing Inks are unique in that theystrongly absorb in the Near IR region of 800nm -1000nm and transmit a highpercentage of light in the visible spectrum (400nm - 700nm). These inks have beenspecially formulated for the production of translucent transaction cards to meet theinfrared wavelength range requirements of the ISO/IEC 7810:2003 specification fortransmission density (O.D.) of 1.3 from 800nm – 950nm and 1.1 from 950nm - 1000nm.   Transaction cards printed with these inks, in accordance with the guidelinesherein, should perform properly in ATM machines and other readers possessing IRsensors to detect the presence of the card.These inks are similar in structure and body to conventional solvent screen inks;however, the highly technical dyes used in their production necessitate specialconsideration in their storage and use. While each screen printing operation has itsown differences and nuances, H. W. Sands IR Blocking Screen Inks are formulated towork around these differences. This bulletin outlines procedural guidelines that shouldbe followed to obtain the optimum, desired results.

Always be surethat the screens, squeegees, knives, spatulas, or any other equipment that comes intocontact with the IR blocking inks are clean and dry, completely free of all solvents orother matter. In addition, the sensitivity of the IR blocking inks to UV light and hightemperatures and specific chemicals should always be considered.

These inks are similar in structure and body to conventional solvent screen inks; however, the complex dyes used in the inks have special requirements for storage and use.
