Re: Exporting as a wmf

["Alan Litchfield" <alan@xxxxxxxxxxxxxxxx>]

You could try looking this up, I don't know that much about CAD programs, but the symptoms 
sound similar.

In many drawing programs there is an option called Hairline for line thickness (and in some 
programs it is set as the default). If you select this line it is set at the thickness of one pixel, which 
on screen looks fine and when it is printed out from its native program -- which takes this 
thickness into account in the printing process -- the results are dandy. Where the problem arises 
is in other formats or programs the default is not recognised, and the line thickness of one pixel is 
taken as an absolute measurement.

Now if you then print this file out from, say, Frame to your DeskJet then the file will determine the 
print results according the content specifications. In other words the line is translated from one 
pixel to one dot on the printer (being an absolute measurement) and so becomes thin. Now to 
exacerbate this further, when you print to a higher resolution laser printer the line will get 
progressively thinner as the resolution increases. To the point where, on an image setter at 2400 
dpi, the line becomes virtually invisible to the naked eye.

To get around the problem set the line thickness to a defined thickness (which would become a 
relative thickness, meaning the lines' thickness increase/decrease if the image is scaled 
up/down), such as 0.5 point to 0.25 point -- 1.0 point is very thick and chunky.
