The settings are governed by your particular needs and are therefore very flexible. Here are a few tips to help you in special cases:

An illustration is to be converted into a raster image so that it can be used in programs, which do not support a more suitable format.

Export your illustration as a line-art drawing. You should obtain a final resolution of approx. 300 – 400 dpi. Enter 300, for example, if the drawing is not to be scaled again later. If, however, it is to be reduced by 50 %, a resolution of 150 dpi will be sufficient.

If you have only used grayscales in your illustration, you should export it as a grayscale image. With color illustrations, a great deal depends on the number of colors you have used. This governs the image depth. By carefully selecting the correct image depth, however, you can reduce the number of colors in a color illustration which may be currently “too good”, e.g. if you want to reduce the size of the file.

The same tips apply for the resolution and compression as for black/white images.
