Ceramic Fiber Heaters Improve 50 Year Old Thermographic Printing Process
Ceramic Fiber Heaters Improve 50 Year Old Thermographic Printing Process Problem: Thermographic printing produces raised lettering, like that found on many business cards. Raised lettering is achieved by melting plastic dust, applied in the shape of lettering, onto the paper's surface while it travels under an array of radiant heaters. Since the 1940's, thermographic printing machines have been using tubular radiant heating elements to effect the melt process. While delivering satisfactory performance, the tubular heating elements had several drawbacks: They consumed excessive power for the actual heat being used. Produced environmental heat, making the work place uncomfortable. Could not evenly distribute heat for fast throughput. Required a larger machine to accommodate space for heating
