Printing apparatus and image processing apparatus

A printing apparatus comprising:

• a conveyance unit configured to convey a print medium in a conveyance direction;
• a printing unit configured to print an image by applying ink to the print medium which is conveyed by the conveyance unit;
• a slitter unit disposed on a downstream side in the conveyance direction relative to the printing unit and configured to cut the print medium along the conveyance direction at a position according to a size of a product in a width direction of the print medium, the width direction intersecting the conveyance direction;
• an image processing unit configured to perform image processing on image data to obtain data for printing;
• and
• a control unit configured to control the slitter unit to cut a width-direction end portion of the printed image after the image is printed based on the data for printing, so as to thereby generate the product,
• wherein the image processing unit
• calculates a first ink application amount of a first area, a second ink application amount of a second area, a third ink application amount of a third area, and a fourth ink application amount of a fourth area, based on the image data, the first area being formed at one end portion in the width direction on a leading edge side of the image which is located on the downstream side in the conveyance direction during printing, the second area being formed at the other end portion in the width direction on the leading edge side, the third area being formed at one end portion in the width direction on a rear edge side of the image which is located on an upstream side in the conveyance direction during printing, the fourth area being formed at the other end portion in the width direction on the rear edge side,
• rotates the image data by 180° 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 and both of the third ink application amount and the fourth ink application amount are equal to or less than the threshold value, and
• enlarges the image data at a predetermined ratio without rotating the image data 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 the threshold value and at least one of the third ink application amount and the fourth ink application amount exceeds the threshold value.

An image processing apparatus that generates data for printing to be used by a printing apparatus for printing of an image, the printing apparatus being configured to generate a product by printing the image by applying ink to a print medium which is conveyed in a conveyance direction and cutting a width-direction end portion of the print medium along the conveyance direction, the width direction intersecting the conveyance direction, the image processing apparatus comprising:

• a calculation unit configured to calculate a first ink application amount of a first area and a second ink application amount of a second area, based on image data, the first area being 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, the second area being formed at the other end in the width direction on the leading edge side;
• an enlargement unit configured to enlarge the image data at a predetermined ratio in a case where at least one of the first ink application amount and the second ink application amount exceeds a threshold value;
• and
• a creation unit configured to create the data for printing by performing image processing on the image data enlarged by the enlargement unit.
