Abstract

According to the present invention, when conveyance abnormality of a medium is determined by using a motion sensor, if the motion sensor fails in image analysis and zero values are returned with respect to a vertical movement amount and a longitudinal movement amount, it cannot be determined whether the zero values are output because the conveyance abnormality occurs or because the image analysis fails. Accordingly, an erroneous determination is likely to be made that conveyance abnormality has occurred according to the output value of the motion sensor even when the medium has been normally conveyed. A medium conveyance device is provided with: a feeding means for feeding the medium in a conveyance direction; and a two-dimensional sensor which is disposed opposite to a surface of the medium conveyed in the conveyance direction, and detects a movement of the medium in a two-dimensional coordinate system including a first axis and a second axis, wherein the two-dimensional sensor is provided in a state in which the first axis and the second axis compose a slope with respect to the conveyance direction.

The present invention suppresses deviation of the printing location of a printing device that prints on the surface of a printing target. According to the present invention, a printing device is moved relative to a printing target, the movement targeting a printing path direction that has been preset in a direction that intersects the direction in which dot-forming elements of a printing head have been arranged, and the degree to which the movement direction of the printing device deviates from the printing path direction is detected. Then, the direction in which the dot-forming elements of the printing device are arranged is altered within the plane of the printing target, and, in accordance with the detected degree of deviation, the arrangement direction of the dot-forming elements is adjusted to approach the arrangement direction for when the printing device is moved in the printing path direction.

Abstract

Conventional ink compositions containing cellulose fibers as a colorant and conventional methods for printing therewith have a problem wherein that high-resolution printing is impossible because the ink compositions run on the recording-medium surface or infiltrate to reach to the back surface. The present invention provides an ink composition which comprises colored cellulose fibers and a dispersion medium comprising water and 1-95 wt% water-soluble organic solvent. Due to this, the colored cellulose fibers serve as a colorant which is apt to be caught in the network of recording media, i.e., as a colorant which has a low coefficient of diffusion in the recording media. This ink composition can have a contact angle with a recording medium of 90° or less so as to have the state of readily wetting the recording medium. Thus, when printed on recording media, the ink composition can be prevented from running or from infiltrating to reach to the back surface.

Abstract

Printing devices in which printing is completed by matching a printing assistance part (such as a UV radiation part) to a printing material (such as a photocurable ink) that is distributed from a printing head onto a printing target experience insufficient correspondence when the direction of movement has changed. According to the present invention, a printing material such as a photocurable ink is distributed from a printing head onto a printing target in association with two-dimensional-direction movement over the printing target, and printing of the printing material onto the printing target is completed by a printing assistance part, such as a UV radiation part, that is arranged in a different location from the printing head by the matching of the printing assistance part to the printing material that is distributed by the printing head. When a printing device moves in association with the distribution of the printing material onto the printing target, the positional relationship between the printing head and the printing assistance part is maintained regardless of the direction of the movement.
