Title: Laser marking method
Inventor: FUJISAWA MASAAKI
IPC: B41M5/34
Filed: 1988-04-19
Abstract: PURPOSE:To make it possible to freely select the colors and the number of coating materials and to give an arbitrary color to a pattern, by controlling the energy of laser light with which to irradiate a coated surface comprising at least two color coating materials on the basis of each part of the pattern so as to remove the coating material(s) to a desired depth, thereby exposing a desired coating material color at the bottom of a hole thus formed. CONSTITUTION:A substrate 10 is a flat plate of a glass or an acrylic resin, and the plate is coated sequentially with, for example, white, red and green coating materials 12, 14, 16 to form a coated surface 18. Laser marking is conducted by irradiating the coated surface 18 with YAG laser light or CO2 laser light from above in a predetermined pattern of characters, symbols, figures or the like. The coating material or materials are removed to a depth according to the irradiation energy of the laser light, resulting in that the red coating material 14 is exposed at a part 20, and the white coating material 12 is exposed at a part 22. Thus, at each part of the pattern, the depth to which the coating material or materials are removed is selected, and one of the green, red and white colors is exposed according to the depth.
