NOTE

edge of the image.
The centre justified image scale, marked on the side of the screen depth adjuster, can only be used
for stencils that are 29 inches by 29 inches with a centre justified image. For other stencil sizes with
a centre justified image, the Rear of Stencil to Front of Image scale must be used.
When using the centre justified image scale, the screen depth adjuster is set to
the board width value. The scale has both imperial and metric units as follows:
●

●
Imperial - 0 inches to 20 inches
