ABSTRACT:
A sheet of writing paper which is white, but which has been colored, or tinted to a pastel color by printing on its surface with a strippable or chemically removable ink. The surface printing with ink allows the paper to have a desirable tinted color, but allows the color to be easily removed so that the paper can be relatively easily recycled and reused without the normal problems associated with recycling of vat-dyed tinted papers. The surface printing can be accomplished by printing a random spotted pattern on the paper to provide for the perception of tinting. The invention allows the printed pattern to have a random-toned effect or allows the visual incorporation of words or symbols which would very subtly appear, macroscopically, in the tinting pattern.
