The scanning window is marked by grid lines that divide the area into square
centimeters. These are numbered 1–29 top to bottom and 1–21 left to right if the light
source is reflective, and 1–23 top to bottom and 1–20 left to right if the light source is
transmissive (see below).
To hide the gridlines, click on the Hide Grid checkbox under Options.
Below the main scanning window is the calibration strip window. Every time the
densitometer calibrates, an image of the calibration strip will appear in this window.
