Once the Track is calibrated you will need to add the horizontal (scale)
grids. Horizontal gridding will remove image stretch from the final digital
output. Vertical grids may also be added, but are not necessary for most
logs.
Add Gridlines to grid the track by using the interactive grid "auto-find,"
or
Use "Force Depth Grids" (shown here) to evenly space the grids on the
track.
