Printing system and printing method

Abstract

A printing system according to an aspect of the present disclosure includes a print head configured to discharge a transparent ink and color ink to a medium, the transparent ink being a colorless, curable liquid, and the color ink being colored liquid; a control unit configured to control discharge of the transparent ink and the color ink, and a sensor. The sensor is configured to optically read and sense a printed result of an adjustment pattern used to adjust a landing position of at least the transparent ink on the medium with the medium moved relative to the printed result along a reading direction. When the adjustment pattern is printed, the control unit is configured to control the print head to form a ruled line having a length component in the reading direction at a position where the transparent ink overlaps with an undercoat layer. The ruled line is configured with multiple structures arranged in the reading direction each having a cross section a surface of which is an arc protruding upward.
