PURPOSE:To enable a sheet to be reused, by erasing a character or image printed with a soluble ink on the sheet, through wiping off the character or image by use of an erasing liquid. CONSTITUTION:The surface of a sheet 101 need not be smooth, but the sheet is preferably impermeable to an ink. For example, a plastic sheet with a surface slightly roughened or treated to appear white is preferable for use as the sheet 101. A soluble ink 102 applied by ink jet recording or the like is collected by wiping with a wiping member 103 impregnated with a correcting liquid, to become a dissolved ink 104. The wiping member 103 is preferably formed of an elastic foamed material so that the member 103 does not come out of contact with the sheet 101 during wiping and can be impregnated with the correcting liquid. An example of such a material is a foamed urethane rubber. Water with or without an alcohol dissolved therein, for example, is effective for use as the erasing liquid for an ink used for ink jet recording. |
