Hi Daan,

I'm not familiar with the Philips machine, so I have stupid rhetorical
question.  Have you tried back lighting so the part appears as a shadow?

(I do agree with your complaint about the color of the part.  CCGA's are the
same way, making them more difficult to do 'all column inspect').

Thanks
