_ _ _ nir ® Technology Overview • Only Ad. Phos has a peak irradiation wavelength of. 8 µm – Most other inkjet drying systems use straight infrared at 2 µm and above. – Other systems using _ _ _ nir (Near. Infra. Red) technology are at 1. 2 µm. 2
_ _ _ nir ® Technology Overview _ _ _ nir ® (Near. Infra. Red) technology enables application of the highest energy quantities on the greatest diversity of substrates 3
Absorption/Transmission of Energy for Inkjet Applications • Black ink absorbs energy across all wavelengths • _ _ _ nir applies more energy to the ink and less to white paper compared to traditional _ _ _ ir 4
Absorption/Transmission of Energy for Inkjet Applications _ _ _ nir Technology 0. 8 µm = 3500 K Infrared Technology >1. 5 µm = 2500 K Paper Mailbase or Reflector • NIR radiation travels through substrates, reflects off of the mailbase or reflector material and dries the ink from top and bottom • IR radiation dries via a “top down” approach. The ink and paper are equally heated from the top only. 5
Benefits of _ _ _ nir® Technology • Greater production speeds and throughput – Due to the greater absorption of energy by the ink and not the substrates, the inks dry approx. 30% faster and more thoroughly than with conventional infrared technology. – Reduced heating of substrates results in less paper curl and improves substrate handling. – Precise energy control / Tool-less lamp replacement • Ability to inkjet on greater variety of substrates – Faster and more thorough drying expands the substrate space printers can image. • One customer expanded their number of coated substrates they were able to print and dry on from 6 to over 30 • With the proper ink formulatuion (ie. Flexprint Aqueous) customers can print and dry at full production speeds on even the most challenging of substrates – even on some plastic card and UV overcoated materials. 6
Benefits of _ _ _ nir® Technology • Reduced operating cost – _ _ _nir® requires approx 30% less power than IR – Patented reflector system reflects >98% of the energy toward where it is needed. 7
