Classification: CPC G | IPC G

Claim 7:
8. A method of printing a quick response (QR) code, comprising:
receiving QR data from a server;
creating a first QR image based on the QR data;
performing image conversion on the first QR image to create a second QR image;
storing the second QR image in a memory; and
printing the second QR image stored in the memory on a curved figure,
wherein the curved figure comprises an egg-shaped curved figure with differ of curvature at points on curved surfaces, and
in the image conversion, lines connecting vertices of the first QR image are modified to be convex while maintaining the vertices of the first QR image so as to create the second QR image allowing QR recognition even on the curved figure.
