Hi morrisphotos123,

I used to print with an Opemus II and I did print colour and Multigrade with it. I used to place the filters atop the condenser. The head bayonets off easily. Make sure you use a UV filter on the top and be careful they don't melt under the heat of the bulb. So it is possible, it just takes a little lateral thinking to achieve it. :-)

Have fun,
