Hi Darja,
The usual answer is to increase the size of the image. For example, if 
you are using the one of the bitmapped devices, the default resolution 
is 480x480 pixels. If you now have 118 pixels/cm (300 dpi) and you were 
using the default resolution, by specifying 800x800 pixels, you should 
get the desired output resolution when the image is scaled to your 
output size.
