Abstract:
A method of using a laser for forming a design on a product selected from the group consisting of fabrics and leathers, comprising:determining, for a specific material of the product, a maximum speed of said specific material relative to the laser, for a given laser power, that will result in a perceivable change for a given laser power, that will result in a perceivable change being formed to said product, and a threshold speed below which at least one of carbonization, undesired burn through or undesired melting of the material of the product will occur; andcontacting a surface of said product with the laser beam to form a design on said surface which changes the surface of the material, and controlling the speed of said laser beam relative to said surface to a range between said maximum speed and said threshold speed.
