How to Determine the Scaling Ratio
When auto scaling is being used, although the scaling ratio is determined by document
size and paper size, it differs according to the scale mode setting.
Note • To activate scaling, set the scaling to ON on the [HP-GL/2 - Programming] screen. If it is set
to OFF, it is plotted at the same scale (100%).
If the Document Size is Auto and the Scaling Mode is Paper Size
The hard clip setting is inactive. The hard clip area is always the paper's hard clip area.
z
If the document size = paper size, it plots at the same scale (100%).
z
If the document size > paper size, it plots at a reduced scale.
z
If the document size < paper size, it plots at the same scale (100%).
If the origin position of the plotting position is Layout, the document is placed and drawn
in the center. If the origin position is bottom left or center, the origin of the document
and the paper are aligned and drawn.
If the Document Size is Auto and the Scaling Mode is ACA
The hard clip setting is inactive. The hard clip area is always the advanced hard clip
area.
The scaling factor is determined according to the ACA and the paper size. The range
for the ACA for each paper size is as follows:
Unit: Plotter Unit
The maximum scaling factor is 210% of the advanced hard clip area for each paper size
and the minimum scaling factor is 22.5%.
