Résumé : |
What is meant by accelerated drying ? Virtually every type of printing ink uses some system or technique to enhance its drying capability. Often this means applying some type of energy to the ink to promote the evaporation of solvent, induce a chemical reaction, or a combination of both. Ovens or kilns and sources of electromagnetic radiation can be used to impart energy to a wet ink or coating converting it to a solid dry film. Electromagnetic radiation includes Radio Frequency (RF), Microwave, Infrared (IR) and Ultraviolet (UV) radiation. Electron Beam (EB) can also be used and this is analogous to UV in terms of the type of materials and chemistry used in ink and coating formulations. The aim of most printers is to achieve the conversion from wet to dry ink as quickly as possible. The most efficient and effective use of energy transfer combined with a similarly reactive ink or coating is going to be most successful in achieving this aim. |
