Abstract
A latent image is formed by applying a colorless liquid that makes colorants of ink insoluble to a predetermined area of a print material. The latent image is made visible by applying ink to only the predetermined area of the print material to cause reaction between the ink and the colorless liquid to make the colorants of the ink insoluble and thereby fix the colorants in the print material. Another method of making a latent image visible involves applying ink to the entire surface of the print material and washing the print material with water to remove unfixed ink.
