Abstract

A test image printer of an inkjet printer causes a test image, including a mark with a predefined shape and usable to correct an image captured by an image capturing device, and a test pattern usable to inspect a plurality of nozzles, to be printed on a recording medium. An image capture controller controls the image capturing device to capture an image of the test image printed on the recording medium. A corrector compares the image of the mark captured by the image capturing device, to the predefined shape of the mark, to calculate a correction value, and corrects the image of the test pattern, captured by the image capturing device, based on the calculated correction value. An inspector inspects the plurality of nozzles based on the image of the test pattern corrected by the corrector.

Abstract

An inkjet printer injects first ink of a plurality of colors and second ink. An extraction condition setter sets an extraction condition to extract a portion of, or an entirety of, ink dots of the first ink of each of the plurality of colors. An extractor extracts an underlying layer dot group from ink dots of the first ink of each of the plurality of colors based on the extraction condition. Such a plurality of underlying layer dot groups and ink dots of the second ink form a first printing layer. An image dot group including at least the ink dots, of the first ink, other than the underlying dot groups forms at least one additional printing layer.

Abstract

An inkjet printer includes an m number of data setters ranging from a first data setter to an m-th data setter, and an m number of print controllers ranging from a first print controller to an m-th print controller, where m is a natural number greater than or equal to 2. Upon receiving data for ink dots, an n-th data setter sets an n-th dot group including some or all of the ink dots, where n is a natural number in a range of from 2 to m. An n-th print controller causes the n-th dot group to be formed over an (n−1) dot group. The first to the m-th data setters set the first to the m-th dot groups so that at least some of ink dots belonging to the first to the m-th dot groups overlap each other.

During standby, a first standby setting processor of a controller sets a first standby state in which a first upstream-side valve is open, and a second standby setting processor sets a second standby state in which the first upstream-side valve is closed. A standby state determination processor determines whether or not the amount of time elapsed from when a setting operation was done by the first standby setting processor or the second standby setting processor is greater than or equal to a first amount of time. The standby state switching processor switches between the first standby state and the second standby state when it is determined that the elapsed time is greater than or equal to the first amount of time.

Abstract

In a slice image creation device, a peeling processor performs peeling on a peeling line segment in a circulation direction of the peeling line segment. When the peeling reaches an intersection at which line segments of contours cross each other, an intersection information acquisition processor acquires intersection information including an intersection angle defined at the intersection by the peeling line segment and each candidate line segment connected to the intersection in a direction that is the same as the circulation direction of the peeling line segment. A transfer processor sets one of the candidate line segments that has the smallest intersection angle as the line segment to which the peeling is going to be transferred next from the peeling line segment at the intersection. A creation processor sets the line segments on which the peeling has been performed continuously as one generated contour and divides a target slice model into a printing region and a non-printing region based on the generated contour to create a target slice image.
