Provided are a printing device and a printing method capable of preventing a reduction in quality and performing printing at high speed. A printing device 1 is provided with: a ring-shaped conveyance belt 11 that has a sheet-shaped printing object C mounted on a surface thereof and is bridged over a pair of rollers 12a and 12b; a driving unit 13 that drives the rollers; a plurality of printing heads 22a to 22d that are arranged along a direction orthogonal to a conveyance direction of a cloth C and perform inkjet printing on a surface of the cloth C; a movement mechanism 30 that moves the printing heads in a direction orthogonal to the conveyance direction of the cloth C; and a control device 41 that causes the printing heads to perform inkjet printing when moving the printing heads while causing the conveyance belt 11 to orbit. The control device 41 controls operations of the driving unit and the movement mechanism so that the printing heads move by a distance corresponding to a printing pitch of the printing heads along a direction orthogonal to a conveyance direction of the printing object every time the conveyance belt 11 makes a round.

The present invention prevents uneven printing from occurring when printing on cloth having a circular shape. Provided is a cloth printing method for color printing, using an inkjet mechanism, on the surface of a cloth C having a circular shape. On the outer peripheral surface of the object-of-printing cloth C which has been placed on a shaft 20, the shaft and/or a plurality of print heads 31a-31f constituting the inkjet mechanism are moved in a length direction X of the shaft 20 while the shaft 20 is also being rotated, and as a result of the foregoing, printing is performed by each of the print heads in a helical fashion on the surface of the cloth C.

Provided are a fabric printing method and fabric printing apparatus with which, when printing a design or background by dot printing on the front surface of a fabric, it is possible to view characters, pictures or background printed on the front surface of the fabric from the back surface, and the front surface is unlikely to exhibit a graininess. This fabric printing method comprises multiple first ink tanks 53 in which multiple process color inks are individually filled and at least one second ink tank 54 in which at least one kind of spot color ink obtained by mixing different process color inks is filled. Printing is carried out on a fabric to be printed which is divided into multiple printing regions that are established on a first surface including one or multiple first printing regions R1, in which dots are printed using ink drawn from at least one of the first ink tanks, and one or multiple second printing regions R2, in which dots are printed using ink drawn from at least one of the second ink tanks.
