There can be an other problem

Due to not coorect installation of the font in question the ghost writer
cannot convert during printing into *.plt file this style correctly.

Try to make a conversation to pdf-xp and see what are the intermediate
reports.

Best greetings

Betreff: [CAD_CAM_EDM_DRO] Re: Corel draw 12 hpgl-plt file not true curves?



I am by no means an expert but I do Some engraving and work with
corel draw 9 for my engravings, HPGL has always out put straight
lines for curves. HPGL-2 was supose to do true curves but I have not
had any software that would read HPGL-2 files and work with my
machines, The only thing I can think of is you may have a coarse
output for your HPGL Files. With corel draw 9 when you save as PLT
file I have a box that pops up for the plt output settings and under
the Page Tab there is a Plotter units setting, the standered for HPGL
output is something like 1016, this is how many line segments per 1"
lines, if this is set to coarse or if you make your drawing to small
for your final output you will see the line segments in the
engraving. When I do My drawings i set the page size to the size of
my plate I will be engraving so I don't have to scale the drawing
after I export it. I don't know anything about corel 12 but it should
have simular settings somewhere.
I hope this helps some,
Jimmy
