Abstract: The invention provides a good inking quality and high inking efficiency lens digital inking device in drum layout. It includes a rotating unit, a lens height adjustment unit, invisible mark recognition unit and print head, utilizing the rotating circumference of the same drum, to completely or partially compensating for the curvature of the front surface of the lens, making the distance between print head to the center or edge of the lens edge reduced, which improves the print quality. This invention is suitable for all kinds of lens inking.
