    Abstract: Techniques are described for dynamically correcting image distortion during imaging of a patterned sample having repeating spots. Different sets of image distortion correction coefficients may be calculated for different regions of a sample during a first imaging cycle of a multicycle imaging run and subsequently applied in real time to image data generated during subsequent cycles. In one implementation, image distortion correction coefficients may be calculated for an image of a patterned sample having repeated spots by: estimating an affine transform of the image; sharpening the image; and iteratively searching for an optimal set of distortion correction coefficients for the sharpened image, where iteratively searching for the optimal set of distortion correction coefficients for the sharpened image includes calculating a mean chastity for spot locations in the image, and where the estimated affine transform is applied during each iteration of the search.

    Abstract: An image-forming system includes an image-forming unit that forms an image of a print job on a sheet having a trimming region based on an image-forming condition; and a processor. The image of the print job includes first and second user images. The processor controls the image-forming unit to form a pattern for adjustment in the trimming region, obtains read image data related to the pattern for adjustment formed on the sheet, and adjusts the image-forming condition based on the read image data. The processor controls a display to display a print preview that represents: the first user image in a print region of the sheet that is different from the trimming region, the second user image in the trimming region, and the pattern for adjustment in the trimming region.

    Abstract: Provided is an image forming system in which an image forming apparatus is connected to a post-processing apparatus having a function of trimming. The image forming system includes: a repeat setting part that determines either: a setting of a scan size of a scan image per one printed reproduction of the scan image, the one printed reproduction being to be laid out by imposition of the scan image; or a setting of the imposition of the scan image according to the scan size of the scan image; a trimming setting part that determines either: a setting of a card size of cards to be obtained by trimming a recording medium; or a setting of a trimming area for the cards; and a coordination part that coordinates the repeat setting part and the trimming setting part.
