Abstract
A printing apparatus for measuring and compensating for a synchronization error is provided. The printing apparatus includes: a rotating part configured to include a roll of which the surface is made of a flexible material and a motor rotating the roll; a support part having a substrate disposed on an upper portion thereof to support the substrate and formed to relatively move in a direction parallel with a tangential direction of the rotating part and the roll; a printing pressure part formed to provide adhesion and printing pressure of the roll to the substrate by changing an interval between the rotating part and the support part; and a compensation unit configured to include a sensor unit which is disposed on a lower portion of the substrate to measure forces which are applied between the roll and the substrate at a contact position between the roll and the substrate and a control unit which performs a control to compensate for the synchronization error by using values of forces measured by the sensor unit.
