H.W. Sands' series of IR Blocking
Screen Printing Inks are unique in that they strongly
absorb in the Near IR region of 800nm - 1000nm and
transmit a high percentare of light in the visible
spectrum (400nm - 700nm). These inks have been
specially formulated for the production of translucent
transaction cards to meet the infrared wavelength
range requirements of the ISO/IEC 7810:2003 specification
for transmission denisty (O.D.) of 1.3 from 800nm
- 950nm and 1.1 from 950nm - 1000nm. Transaction
cards printed with these inks, in accordance with
the guidelines, should perform properly in ATM machines
and other readers possessing IR sensors to detect
the presence of the card. |
