b&w printing - colour enlarger

[Solarize]

I have an LPL C6700cx colour enlarger but want to do b&w printing. Does anyone have any advice on using the built in filters to change the grade. i.e. what ones I should adjust and how much I need to move them to achieve results similar to those I would get if I used an under the lens filter system like Illford's.

Thanks

Generally, you'll add magenta to increase contrast in a B&W print - and add yellow to decrease it. When you run a test strip, start with filtration at zero to see where you're at with your negative, until you develop a feel for what works. A lot will also depend on what paper type you're using: multigrade or graded. Doubtful you'll have much use for the cyan, unless you're trying to be creative.

Damn, never thought of that. My bundle cam with a dichor67S2 color head with 35mm and medium format mixing chambers. And to think I was just about to drop some dough on filters. Thanks for the inadvertent inspiration, Solarize.
