| The distance (space interval) of the line image continuously printed at constant intervals between the width of a center distance of the distance (address) from an arbitrary starting point to each line and the adjoining line (line pitch) and each line and the adjoining lines is measured at the same time. |
Alignment at the print position is measured while minute adjusting the position of view so that the print of a cross line of the CMYK4 color may become the center of the image for center coordinates (coordinates to an arbitrary starting point). |
The alignment of column of the CMYK4 color line is measured for center coordinates. (coordinates to arbitrary starting point) |
The view distribution of each view is measured while moving the stage of the patch and the gray scale of the test chart.
Data measures the maximum, the minimum in each view, and the average, the peak brightness, and the brightness standard deviation by 256 step displays.
|
The stage is moved to an arbitrary location on the sample, and the area of making to binary of each view is obtained . The print accuracy and the reproducibility of the dot are evaluated. |
