Printing apparatus and manufacturing method of printed matter

A printing apparatus that performs printing on a printing medium, comprising:

• an ejecting unit that reciprocates in a main scanning direction which is a width direction of the printing medium, ejecting a liquid onto the printing medium when moving at least in a forward direction of the main scanning direction;
• and
• a control unit that controls an operation of the printing apparatus,
• wherein in one movement of the ejecting unit in the forward direction, the control unit includes a first operation mode in which a moving distance D of the ejecting unit is set to be expressed by the following formula (1), and a second operation mode in which a moving distance D of the ejecting unit is set to be expressed by the following formula (2), and
• wherein the control unit performs the printing in the first operation when the width of the image to be printed on the printing medium is a predetermined value or more, and performs the printing in the second operation mode when the width of the image is less than the predetermined value.
• D=G+α (formula 1)
• D=G+β (formula 2)
• wherein, G is the width of the image to be printed on the printing medium.
• β>α≧0
