A printing machine is provided with: a substrate feeding mechanism that sends out a web-shaped substrate; a conveying mechanism that conveys the substrate while holding the substrate sent from the aforementioned substrate feeding mechanism; and a carrier, which is arranged on Between the aforementioned substrate sending mechanism and the aforementioned conveying mechanism, the upper surface supports the substrate; the substrate holding mechanism keeps the substrate on the upper surface of the stage; the stage position adjustment mechanism adjusts the position of the stage Position; and a pattern forming mechanism that prints ink on the substrate on the stage to form a pattern; and is characterized by including: a control mechanism that controls the substrate holding mechanism to hold the substrate on the stage After the upper surface, while the substrate is held by the substrate holding mechanism, the substrate feeding mechanism is controlled to relax the tension of the substrate between the substrate feeding mechanism and the stage, and the substrate is controlled. After the transport mechanism relaxes the tension of the substrate between the carrier and the transport mechanism, the carrier position adjustment mechanism is controlled to adjust the position of the carrier, and the control mechanism is controlling the carrier position adjustment mechanism to adjust the position of the carrier. After the position of the stage, the pattern forming mechanism is controlled to print ink on the substrate on the stage to form a pattern. The printer of claim 1, wherein the control mechanism controls the pattern forming mechanism to print ink on the substrate on the stage to form a pattern, and then controls the substrate delivery mechanism so that the substrate delivery mechanism and the aforementioned The tension of the substrate between the stages is restored to just before relaxation And control the conveying mechanism to restore the tension of the substrate between the carrier and the conveying mechanism to the magnitude immediately before the relaxation. The printer of claim 2, wherein the control mechanism controls the substrate delivery mechanism to move the substrate from the substrate delivery mechanism toward the carrier when the tension of the substrate between the substrate delivery mechanism and the stage is relaxed. The table sends out the substrate. On the other hand, when the tension of the substrate between the substrate sending mechanism and the carrier is restored to the magnitude immediately before relaxation, the substrate sending mechanism is controlled to match the substrate with the already sent The length of the same length is rolled back from the carrier toward the substrate feeding mechanism; and when the tension of the substrate between the carrier and the transport mechanism is relaxed, the transport mechanism is controlled to move from the transport mechanism to the carrier Pull back the substrate, and when the tension of the substrate between the carrier and the conveying mechanism is restored to the magnitude before relaxation, the conveying mechanism is controlled to move the substrate from a length equal to the length that has been pulled back from The carrier is sent to the conveying mechanism.
