Ink jet printing demands that excess water on the surface of the printed substrate be removed within a set time. In addition, other requirements should be met: acceptable print quality, low sheet deformation, minimal strike-tnrough, minimal feathering. The set time is ictated by substrate path and substrate process speed. Mechanisms to remove the water from the surface are referred to as dryers. A slow drying rate can result in image offset or smear, excessive image spreading or penetration which will result in deformation due to stress relaxation. Typical drying mechanisms are: surface evaporation, diffusion of ink into the substrate or surface blotting . In the present study, various experimental methods and techniques for efficiently drying inkjet images printed with aqueous ink formulations on plain paper have been developed ana where applicable, numerical analysis have been correlated with experimental data.The drying methods which have been explored should be able to satisfy drying requirements of Ink Jet printers and copiers with a wide range of substrate throughput. Highlights of conductive, convective and infrared drying and combinations thereof are presented. The metrics for defining acceptable drying in terms of moisture content of paper and image offset density are discussed. Criteria for choosing the optimum dryer so as to optimize trade offs between power consumption, cost, size, architecture and efficiency are also discussed.
