Embodiment Construction

[0048] figure 1 The reflection of light at the product surface 1, which is shown in cross-section, is demonstrated. Incident light 2 impinges on the product surface 1 . Depending on the reflective properties of the not further shown surface contour 3 of the product surface 1 , part of the light 41 is absorbed by the product surface 1 and the other part of the light 4 returns, ie is reflected. The intensity of reflected light 4 is direction-dependent and influenced by surface contour 3 . The direction and intensity of the incident light 2 , absorbed light 41 and reflected light 4 are shown by the direction and length of these arrows. A portion of the reflected light 4 enters a detector 16 of the optoelectronic reading device, which detects the intensity of this light in a spatially resolved manner.

Abstract

The invention relates to a product surface (1) having an optoelectronically readable code (5) which is formed by an arrangement of flat cells (6, 7) of different cell types and to a method for producing such a product surface (1). The aim of the invention is to provide such a product surface (1), the legibility of the code (5) being robust against loads. This is achieved in that the cells (6, 7) are an integral component of the product surface (1), each cell (6, 7) of each cell type having a profiled surface (3). The profiled surface (3) of at least one cell type has at least one elevation and / or depression relative to the product surface (1), and the profiled surface (3) of a first cell type is designed relative to the profiled surface (3) of a second cell type such that the profiled surfaces differ in terms of reflective properties.

Description

technical field [0001] The invention relates to a product surface with an electro-optical readable code formed by arranging planar cells of different cell types, its use and a method for its production. Background technique [0002] Product information can be displayed in a simple manner by means of an optoelectronically readable code. Examples of this are the product number shown by a barcode or the Internet address (Uniform Resource Locator) shown by means of a QR code, which indicates, for example, the Internet page of the manufacturer of the product. Here, such coded cell types must differ sufficiently in their optical contrast that the cells can be sensed and differentiated by an optoelectronic reading device. Usually a code has two cell types which differ in their colour, for example in their hue and / or their color saturation and / or their lightness value. This results in an optical contrast in the brightness or intensity of the light reflected by the cells of the dif...
