Abstract

In the current state of the art only flammable-or solvent-type correcting fluids opaque and, therefore, correct print from water-based ink without redissolving the dye from the print. Overprinting is usually unsuccessful because of the wetting properties of the dried (or wet) opaque material. Water based, nonflammable correcting fluids may be overprinted, but the resultant print is unacceptable due to diffusion of the applied ink and 'greying' of the applied correcting material as a result of redissolving dye by the correcting fluid. Another problem occurring with aqueous-based correcting fluids is the lengthy drying period for water evaporation to yield a dry film before a new character can be reprinted.
