For printing I set the colours as full CMYK so it wouldn't be just
black ink, however I\ufffdm afraid that my printer doesn't let me use any
other cartridges except the original ones.

I guess the best thing would be, in the future, to buy a laser printer
for this purposes.


The cheap HP 5940 DeskJet I use works very well, but needs the more 
expensive JetStar Premium film. I can get down to 5 mil tracks if I need 
them (I never have).
