Abstract
A printing method and a printing device are provided to reduce a difference in a degree of wet-spreading of a coating material. The printing method includes: a buffer layer forming step of forming, when there is a difference between a surface free energy of a print object which is an object to be printed and a surface free energy of a coating material applied to a surface of the print object, a buffer layer on the surface of the print object with a buffer material having a surface free energy differing from that of the print object or the coating material; and a printing step of printing by applying the coating material to the buffer layer.
Claims20
A printing method comprising:
- a buffer layer forming step of forming, when there is a difference between a surface free energy of a print object which is an object to be printed and a surface free energy of a coating material to be applied to a surface of the print object, a buffer layer on the surface of the print object with a buffer material having a surface free energy differing from that of the print object or the coating material;
- and
- a printing step of printing by applying the coating material to the buffer layer.
A printing device comprising:
- a droplet ejecting portion, configured to be capable of ejecting droplets of a coating material toward a surface of a print object;
- a buffer layer forming portion, configured to be capable of forming a buffer layer that adjusts an arrangement state of the coating material on the surface of the print object;
- and
- a controller, configured to cause the buffer layer forming portion to form the buffer layer and the droplet ejecting portion to apply the coating material onto the buffer layer, when an absolute value of a difference between a surface free energy of the print object and a surface free energy of the coating material is equal to or greater than a threshold.
A printing method comprising:
- ejecting droplets of a first ink from a nozzle of a first head onto a print object while moving the first head in a main scanning direction set in advance;
- and
- ejecting droplets of a second ink having a higher viscosity than that of the first ink from a nozzle of a second head onto the print object, the second head being arranged side by side with the first head in the main scanning direction and moving integrally with the first head,
- wherein
- the droplets of the first ink and the droplets of the second ink are ejected in an overlapping manner so as to correspond one-to-one on target landing positions for the droplets of the first ink on the print object.
