Hi David, Thanks for your help. I tried PROCESSING "SCALE=AUTO". This method results in a red/white image. All the labels in the map are drawn red (originally black). The whole topographic information in the background is just white (originally many different colors). I tried it with a combination of different outputformat-declarations and processings. Unfortunately I didn't get a correct result.
