  • Publication number: 20220281239
    Abstract: Provided are an inkjet printing method and an ink set, in which forward and reverse warp inks are printed in an arrangement that reduces warp. The forward warp ink is the ink in which a warp when cured and shrunk by irradiation of light is a forward warp in which a portion on a side where light is irradiated by a light irradiation device is large in the degree of curing and shrinkage as compared with a portion on an opposite side. The reverse warp ink is the ink in which a warp when cured and shrunk by irradiation of light is a reverse warp in which a portion on a side opposite to a side where light is irradiated by the light irradiation device is large in the degree of curing and shrinkage as compared with a portion on the side where light is irradiated.

  • Patent number: 10940695
    Abstract: The present disclosure prevents a visible pattern corresponding to the pattern of a mask from being noticeable and enables more appropriate printing. A printing apparatus 10 performing printing by an inkjet scheme includes: an inkjet head 102; and a controller 20, configured to control the operation of a main scan driver 16 and a sub scan driver 18 to perform a main scanning operation multiple times on each position on a medium 50. In the main scanning operation, for at least part of ejection positions serving as ejection targets of ink droplets in the main scanning operation, the controller 20 causes the inkjet head 102 to eject an ink droplet in accordance with a mask for selecting part of the at least part of ejection positions. In the main scanning operation at one time, the controller 20 causes the inkjet head 102 to eject an ink droplet in accordance with a preset first mask.
