Abstract: In a printing method, is obtained position information of an invisible region invisible from outside, out of the printing surface of the packaging base material. Then a flushing process in which ink is ejected the ink toward the invisible region from the nozzle based on the position information is performed. Therefore, printing for packaging pouch can be satisfactorily performed on the packaging base material without impairing the design quality of the packaging pouch manufactured by applying the bag making process to the packaging base material.

Abstract: A data processing method for repeatedly recording a first basic pattern image and a second basic pattern image on a base material includes the following a) and b). In the a), the first basic pattern image (D1) and the second basic pattern image (D2) are stored. In the b), a pixel value to be recorded is calculated for each recording layout coordinate set indicating a position on the base material.

Abstract: Image data is accurately resized in real time by downscaling. An image signal generating apparatus includes a parameter generator that dynamically generates a parameter PM and an image signal generator that repeats processing of generating an output image signal Q in response to each sampling signal B. Each parameter includes a division ratio parameter DP. The division ratio parameter DP corresponds to a ratio of a second time period Tb and a third time period Tc other than the second time period Tb. The second time period Tb is a time interval until the generation of a sampling signal Bn in a first time period Ta until input of an immediate timing signal Ak+1 since input of a last timing signal Ak. The image signal generator repeatedly generates a first weighted signal and a second weighted signal of the image signal in response to each sampling signal Bn.
