SVG ➠ multicolour print

Tips

Make sure the various colours in the SVG are non-overlapping paths.

In Inkscape:

• Convert all objects into paths (Paths > Objects to Path)
• Convert any strokes into paths (Paths > Stroke to path)
• Duplicate any overlapping colour and subtract it from the covered colour (Edit > Duplicate; Path > Difference)

If you want to have a solid coloured base:

• Select the colour that bounds your object
• Duplicate it
• Path > Break apart
• Delete all paths inside the bounding path
• Make it a different colour from all others
• Set depth to a negative number

To preserve detail use 'Arachne' slicing.
