[Scribus] Image export dpi problem

[spiff]

Hi,


I always export as eps, then import the image in The Gimp. i always have 
to ensure antialias is set to "strong" for both images and text and the 
resolution dpi imported is higher than i require (i use 600dpi i then 
scale down the image in the gimp to 300 dpi before sending to the 
printing company)

they key is to export as eps, use a high import resolution and use 
antialias when importing into the gimp!

It works very well, and I have had a number of images professionally 
printed using this method.
