Laser engraving a state of the art marking technology of the Euroseal (r) products. It produces a resistant print which can be formed from even very thin lines, have complicated logos or symbols. It is of course possible to print both number and bar code. The print is always monochromatic and the color of print can not be selected. Light colors are marked directly onto the seal, darker colors use extra white background for higher contrast and better readability. Use of the laser marking is suitable for applications requiring more complicated seal marking, bar code and increased mechanical resistance of the marking.
To be able to mark a plastic seal by laser, special pigment powder has to be added into the material for molding. The powder provides better contrast of the marking and does not modify the material qualities of the seal. During the marking process, the laser beam gets in contact with the material and by means of the produced heat creates the required marking of the seal.
