Hi Claire, You can set a general scale factor for lines when printing on Postscript. do: gStyle->SetLineScalePS(scale); The default in ROOT for scale is 3. You can set it to 1 if you like. Note that you can place the line gStyle->SetLineScalePS(1) in your rootlogon.C file. You do not have to change the line width in your scripts.
