  • Patent number: 11766882
    Abstract: A printing apparatus includes an image processing unit and generates a product by performing printing on a print medium conveyed in a conveyance direction intersecting a width direction, based on data for printing, and then cutting a width-direction end portion of a printed image, wherein the image processing unit calculates a first ink application amount of a first area formed at one end portion in the width direction on a leading edge side of the image which is located on a downstream side in the conveyance direction during printing and a second ink application amount of a second area formed at the other end in the width direction on the leading edge and enlarges the image data at a predetermined ratio to obtain the data for printing in a case where at least one of the first ink application amount and the second ink application amount exceeds a threshold value.

  • Patent number: 8262216
    Abstract: Even if a liquid is attached and solidified on a peripheral surface of a coating roller, application of the liquid on a medium is uniformly performed. At least a part of contacting member is separated from the coating roller and the coating roller is rotated in a second direction as a reverse direction to a first direction to pull out the liquid from a liquid retaining space onto the coating roller. Next, by interrupting the above separation and rotating the coating roller in the first direction, a liquid reservoir is formed in the periphery of a contacting portion between the coating roller and the contacting member.
