Normally the KIP 700m takes 600 times of image exposure per inch for the vertical direction
as its resolution is 600DPI. Pixels created by this normal timing are called [Main Pixel].
When a specific image pattern (like a diagonal line) is printed, however, the KIP 700m will
make additional image exposure between vertically neighboring 2 Main Pixels. This
additional image exposure is completed within a very short time. The pixel created by this
additional process is called [Supplemental Pixel].

Main Pixels
Supplemental Pixels are provided so as to fill the space between Main Pixels.
When we compare a vertical / horizontal 1 dot line and a diagonal 1 dot line, for example, the
diagonal one looks vague and rough although the vertical / horizontal one looks clear and
smooth.
This is because the diagonal line has a wider space between Main Pixels than the vertical /
horizontal one.
If this space is filled with the Supplemental Pixel, diagonal line comes to look smoother and
clearer.
No Supplemental Pixel Supplemental Pixels are provided.
