Abstract
A printing apparatus includes a pattern extracting unit for, based on a comparison between first image data representing a pattern and second image data generated by imaging a fabric transported, extracting a pattern region from the second image data, a printing image generation unit for arranging third image data representing an image to be printed overlaid on the pattern so that the third image data matches the pattern region to generate printing image data, and a printing control unit for causing a printing unit to print the printing image data on the fabric transported.
Claims6
A printing apparatus, comprising:
- a transport unit configured to transport a fabric formed with a pattern in a transport direction;
- an imaging unit configured to image the fabric transported by the transport unit;
- a printing unit configured to perform printing on the fabric transported by the transport unit;
- a pattern extracting unit configured to, based on a comparison between first image data representing the pattern and second image data generated by imaging the fabric by the imaging unit, extract a pattern region corresponding to the pattern in the second image data;
- a printing image generation unit configured to arrange third image data representing an image to be printed overlaid on the pattern so that the third image data matches the pattern region extracted, to generate printing image data;
- and
- a printing control unit configured to cause the printing unit to print the printing image data on the fabric, wherein
- the pattern extracting unit performs
- first extracting processing for extracting the pattern region from a first region of the second image data, and
- second extracting processing for extracting the pattern region from a second region of the second image data,
- a part of the second region is an overlapping region overlapping the first region, and
- a length in the transport direction of the overlapping region is equal to or greater than a length in the transport direction of the first image data.
A printing method, comprising:
- a transport step for transporting a fabric formed with a pattern in a transport direction;
- an imaging step for imaging the fabric transported;
- a pattern extraction step for, based on a comparison between first image data representing the pattern and second image data generated by imaging the fabric, extracting a pattern region corresponding to the pattern in the second image data;
- a printing image generation step for arranging third image data representing an image to be printed overlaid on the pattern so that the third image data matches the pattern region extracted, to generate printing image data;
- and
- a printing step for printing the printing image data on the fabric transported, wherein
- the pattern extraction step includes performing
- first extracting processing for extracting the pattern region from a first region of the second image data, and
- second extracting processing for extracting the pattern region from a second region of the second image data,
- a part of the second region is an overlapping region overlapping the first region, and
- a length in the transport direction of the overlapping region is equal to or greater than a length in the transport direction of the first image data.
