The invention relates to a method for marking a wrapping paper for smoking articles, comprising the following steps: (A) providing a wrapping paper for smoking articles, and (B) producing register marks on the wrapping paper by treating the surface of the wrapping paper with laser radiation having an energy density y in J-m-2, to which the following applies: y=k.Math.x, whereby x is the enthalpy of combustion per volume of the wrapping paper in J.Math.m.sup.−2.Math.μm.sup.−1, and k is at least −8 μm and at most −1 μm.

Laser-markable cable layers for a cable are provided. The laser-markable cable layers include an inner layer formed of a first polymer material and an outer layer formed of a second polymer material and a laser-marking compound. The outer layer is about 0.5% to about 50% of the thickness of the inner layer. The laser-markable cable layers surround a wire or cable core. Methods of marking a cable having laser-markable cable layers are also provided.

Kits and methods are provided for color customization of articles by applying ink to regions of decreased pigment density. By creating tension over these regions during application of the ink, the ink may be preferentially transferred to those regions.

A device for inscribing identification units, each identification unit including an identification plate or connected single-piece identification plates, each identification plate having an inscription surface, and the inscription surface or a plurality of the inscription surfaces of each identification unit spanning an inscription plane, includes a housing; an inscription device that is arranged in the housing, particularly a laser inscription device; a drop shaft which is arranged in the housing, is accessible via an inlet opening in the housing, is designed for conveying individual identification units to the inscription device, and is delimited by at least one chute for the identification units, the chute being at an incline relative to the horizontal and vertical lines; a support surface which is arranged at the lower end of the drop shaft and spans a support plane in order to support an edge of the identification units; a stopping block that protrudes upwards over the support plane or is arranged over the support plane; and a counter holder that can move towards and away from the stopping block in a feed direction, in order to press identification units that are supported on the support surface against the stopping block, in an inscription position.

A theft deterrent product may be provided. First, a plurality of unique codes may be created. Then a plurality of indicia may be placed periodically and longitudinally on the product. The plurality of indicia may respectively correspond to the plurality of unique codes. The product may have an outer layer and into an portion. Placing the plurality of indicia may comprise etching through the outer layer and into the inner portion. In a database, the plurality of unique codes may be assigned to an organizational entity. The organizational entity may comprise a first enterprise.

A laser etching system for forming customized image patterns on workpieces, includes a computer that receives a product image and generates a label image, a laser head to emit a laser beam, a transport system that can scan the laser head across a workpiece or a label associated with the workpiece, a laser head driver that can modulate the laser beam in accordance to the product image or the label image that uniquely identifies the workpiece, and a power controller that can set the laser beam a first power level or a second power level. The laser head can scan across and etch the workpiece at the first power level in pixel-wise fashion to reproduce the product image on the workpiece. The laser head can scan across and etch the label at the second power level in pixel-wise fashion to reproduce the label image on the label.

Disclosed a laser marking machine, method, equipment and system. The method comprises steps of: the control main board receiving coordinate and gray scale value of the target image pixel dot; calculating output power of the target image pixel dot by using the gray scale value; and controlling the laser device to use corresponding output power according to displacement of the galvanometer, and outputting laser specific to each target image pixel dot. By adjusting the output power of target image pixel dot (marking point), a separate pixel dot may reflect the change of gray scale value, so as to represent the image gray scale value. The coordinate of each pixel dot in the gray scale image may be calculated according to the predetermined resolution, such that, the coordinate of pixel dot is no longer adjusted, ensuring the DPI and the resolution of the gray scale image.
