摘要： In an image recording apparatus, only small ink droplets are ejected toward a recording medium in the range of tone values less than a second tone value. In the range of tone values greater than or equal to the second tone value and less than a first tone value, large and small droplets are ejected toward the recording medium. The first tone value is less than or equal to a 50% tone value, and the total ejection rate at the first tone value is less than 50%. In the range of tone values greater than or equal to the first tone value, only large droplets are ejected toward the recording medium. Thus, the occurrence of streaking can be suppressed while reducing the degree of instability of the landing positions of tine droplets of ink.

摘要： MTF characteristics of a concavo-convex forming apparatus change depending on the amount of amplitude of input data, the operation condition of the apparatus, etc., and therefore, it is not possible to form a concavo-convex shape with good characteristics only by applying the MTF correction technique widely known in the image processing field. A concavo-convex forming apparatus including an input unit configured to input concavo-convex data representing concavo-convex of an object to be printed, and a correction unit configured to perform correction in accordance with a plurality of frequency band of the input concavo-convex data and whose intensity is made higher for the larger amplitude on the input concavo-convex data based on frequency response characteristics in a case where concavo-convex is formed on a printing medium.

摘要： Printheads and methods for forming printheads are described herein. In one example, a printhead includes a number of drop generators, wherein a pitch between each adjacent drop generator is substantially the same, and the drop generators alternate between a high drop weight (HDW) drop generator and a low drop weight (LDW) drop generator. The printhead also includes a flow channel from an ink source leading into an ejection chamber associated with each drop generator, wherein the flow channel comprises an inflow region proximate to the ink source, wherein an area of the inflow region is adjusted to control the flux of ink into the ejection chamber.

摘要： There are provided an image formation device, an image formation method, a program, and a formed image capable of preventing noise and granularity of an image from deteriorating even when dots with a plurality of dot sizes are arranged to be aggregated. When a continuous tone image signal is a signal which indicates a tint image, at least one of dot aggregation portions 16, 18, 68, and 72 is formed through arrangement for aggregation of dots 14 (dots 14L and 14S) with two or more dot sizes, on a part of dot images 10, 12, 66, and 70 which are indicated by dot image signals. In addition, the dot aggregation portions 16, 18, 68, and 72 are formed through arrangement for non-aggregation of the dots 14 (dots 14L) with at least one dot size.
