| description | An object having a visible pattern including invisible information printed thereon and a method of reading visible information and invisible information from such an object. The object (4) has a bar code pattern (22) printed thereon. A region (6) having the bar code pattern (22) printed therein comprises a portion (10) printed in first ink (24) and a portion (8) printed in first ink (24) and second ink (26). The first ink has light absorption characteristics the same with respect to visible light and infrared light and the second ink has light absorption characteristics varying with respect thereto. By scanning the region (10) by the infrared light, visible information can be obtained and by scanning the region (8) by the infrared light, invisible information, that is, information included in the visible pattern can be obtained. |
