An image forming apparatus includes a selection unit configured to select a sheet type, an image processing unit configured to perform image processing on image data, based on a correction condition that corresponds to the selected sheet type, a conveyance unit configured to convey a sheet, and an image forming unit configured to form an image on the sheet, based on the image data, wherein the image processing unit performs the image processing on the image data, based on a first correction condition that corresponds to a sheet to be conveyed by the conveyance unit in a first direction, and wherein the image processing unit performs the image processing on the image data, based on a second correction condition that corresponds to a sheet to be conveyed by the conveyance unit in a second direction, the second direction being different from the first direction.

An image processing apparatus for a printing apparatus. The image processing apparatus includes a recording position acquiring device for acquiring recording positions of a reference image printed by a reference print head and a target image printed by a target print head, a positional deviation amount calculating device for calculating a deviation amount due to a skew with respect to the recording positions of the reference image and the target image, and a positional deviation interpolation image converting device, when there is a remainder of the deviation amount and the predetermined intervals, for adding a weight based on the remainder, and adding a smaller weight than the weight to the reference image or the target image without a remainder and adjoining the reference image or the target image with the remainder, thereby converting the image into a width direction positional deviation interpolation image.

A printing system includes a first imaging unit configured to print a first image and a registration mark associated with the first image on a web contemporaneously during a production run, and a sensor configured to detect the registration mark at a point where the registration mark is within a second imaging unit. The printing system further includes a controller configured to calculate an offset along a width direction of the web based on the registration mark and to instruct the second imaging unit to print the second image on the web. The second image is shifted in its entirety in accordance with the calculated offset and is printed on the same side of the web as the first image.

A tape having a strip shape extending in a lengthwise direction and a widthwise direction includes: a subject surface located on the tape and exposed in a thickness direction; a first marker provided on the subject surface and being greater than the subject surface in reflectivity to light with a particular wavelength; and a second marker provided on the subject surface and being less than the subject surface in the reflectivity. At least a portion of the first marker and at least a portion of the second marker are identical to each other in position in the widthwise direction. At least a portion of one of the first marker and the second marker and at least a portion of another of the first marker and the second marker are different from each other in position in the lengthwise direction.
