Title:
印刷装置及び印刷媒体の変形検出方法
Document Type and Number:
Japanese Patent JP6386387
Kind Code:
B2
Abstract:
Provided is a printing apparatus having a printing unit with recording elements arranged in a width direction of a print medium. The printing apparatus includes a printer printing a correcting chart to the print medium, a correcting-chart density information obtaining device obtaining density information on the correcting chart printed to the print medium, and a print-medium deformation determining device setting at least two different numbers of the recording elements as moving average widths from the density information on the correcting chart, calculating moving average values of the density information of the recording elements for the moving average widths, calculating a standard deviation using the moving average values for the small and large moving average widths, respectively, and determining that deformation occurs in the print medium when the standard deviation used as a determination value exceeds a threshold.
