PRINTER, PRINTING SYSTEM, AND PRINT MANUFACTURING METHOD
An input unit receives first image data corresponding to a watermark image by a first glossy ink. An image data transmitter composes the first image data and data representing a basic transfer pattern as a background of the watermark image to create and send second image data representing a watermark composite image. The basic transfer pattern is configured to transfer the first ink so that first pixels to which the first ink is transferred and second pixels to which the first ink is not transferred are dispersedly mixed. A printing unit prints a third image based on third image data printed using a second ink on a print body and prints the watermark composite image based on the second image data using the first ink on the print body to form a watermarked image including the third image and the watermark composite image superimposed on the print body.
1 . A printer comprising:
an input unit configured to receive first image data corresponding to a watermark image by a first glossy ink;
an image data transmitter configured to compose the first image data and data representing a basic transfer pattern as a background of the watermark image to create and send second image data representing a watermark composite image, the basic transfer pattern being configured to transfer the first ink so that first pixels to which the first ink is transferred and second pixels to which the first ink is not transferred are dispersedly mixed; and
a printing unit configured to print a third image based on third image data printed using a second ink on a print body, and to print the watermark composite image based on the second image data using the first ink on the print body to form a watermarked image including the third image and the watermark composite image superimposed on the print body.
2 . The printer according to claim 1 , wherein the basic transfer pattern is a checkerboard pattern.
3 . The printer according to claim 1 , wherein
the input unit is configured further to receive fourth image data printed using the second ink, and
the image data transmitter is configured to create the third image data based on the fourth image data and data representing the basic transfer pattern.
4 . The printer according to claim 3 , wherein the image data transmitter is configured to create the third image data so that when the second ink includes yellow ink, magenta ink, and cyan ink, in the background of the watermark image, the yellow ink is transferred to either the first or second pixels while the magenta ink and cyan ink are transferred to the others.
5 . A printing system comprising:
a printer; and
a printer driver configured to send image data to the printer, wherein
the printer driver comprises:
an input unit configured to receive first image data corresponding to a watermark image by a first glossy ink; and
an image data transmitter configured to compose the first image data and data representing a basic transfer pattern as a background of the watermark image to create and send second image data representing a watermark composite image, the basic transfer pattern being configured to transfer the first ink so that first pixels to which the first ink is transferred and second pixels to which the first ink is not transferred are dispersedly mixed; and
the printer comprises
a printing unit configured to print a third image based on third image data printed using a second ink on a print body, and to print the watermark composite image based on the second image data using the first ink on the print body to form a watermarked image including the third image and the watermark composite image superimposed on the print body.
6 . A method of manufacturing a printed matter, comprising:
receiving first image data corresponding to a watermark image by a first glossy ink;
composing the first image data and data representing a basic transfer pattern as a background of the watermark image to create second image data representing a watermark composite image, the basic transfer pattern being configured to transfer the first ink so that first pixels to which the first ink is transferred and second pixels to which the first ink is not transferred are dispersedly mixed; and
printing a third image based on third image data printed using a second ink on a print body and printing the watermark composite image based on the second image data using the first ink on the print body to manufacture the printed matter with a watermarked image formed thereon, the watermarked image including the third image and the watermark composite image superimposed on the print body.
