PURPOSE:To correctly see a character or a figure through the front surface by printing an inverted character or an inverted figure with normal printing ink on the back surface of a normal sheet, and forming the front surface transparently or translucently. CONSTITUTION:A character or a fiture on the back surface can be seen through merely by using a normal printing ink 2 on the back surface of the sheet and printing the front surface with transparent ink 3. Thus, the character or the like is normally printed on the back surface and the ink 3 is printed from the front surface, but the ink 3 may be printed on the back surface of the sheet 1 and the character may be printed thereon with normal ink 2. Further, even when the ink 3 is printed on the front surface, or when transparently printing ink is printed on the printed character, the same object and effect can be attained. |
