Problems solved by technology

[0007] However, since the blade is maintained in a state where the blade is in contact with the transfer body, the contact portion between the blade and the transfer body may be worn due to friction during driving of the transfer body.
In addition, defects (for example, debris, etc.) due to vibration transmitted from the transfer body are generated on the surface of the blade
[0008] As a result, printing defects (eg, spots, streaks, etc.) may be caused when the printing paste is transferred from the transfer body to the substrate
