    摘要: The invention relates to a method for applying a marking on an object according to image data, wherein the image data comprises pixels with first pixel values and pixels with second pixel values, and wherein the marking to be produced comprises several cells, each cell corresponding to one pixel of the image data, in which at least one light beam is emitted with light emitting means; a deflection direction of scanning means for deflecting the light beam is scanned over the object; when the deflection direction points at a cell corresponding to a pixel with a first pixel value, the light emitting means are activated to produce a mark in that cell; and; when the deflection direction points at a cell corresponding to a pixel with a second pixel value, the light emitting means are deactivated to leave that cell blank. The method is characterized in that the deflection direction is altered in a meander pattern for cells that correspond to pixels with first pixel values, and in a straight movement for cells that correspond to pixels with second pixel values. The invention further relates to a marking apparatus for applying a marking on an object.
