Abstract: An improved drying apparatus for screen process printing and coating, using water-based inks and coatings, whereby a novel combination of a forced hot air dryer and radio frequency dryer is provided. The principal advantages of the present invention as compared to the prior art reside in the significant savings in floor space requirements and power requirements for high produciton (i.e., 2,000-3,000 impression per hour) screen process printing and coating operations which have heretofore utilized a 40 foot length hot air drying apparatus which suffers from a number of disadvantages as previously described. The RF dryer and hot air dryer portions of the present invention are serially arranged on a common conveyer belt apparatus and may be combined with an optional air conditioning cooler which is positioned on the output side of the radio frequency dryer for cooling the cured ink or coating material as it exits from the radio frequency dryer.
