I recently bought an enlarger with a colour head (CMY) and am looking for advice on contrast filtration for B&W paper. My experience is in graded paper, and Ilford filters for multicontrast varieties in a drawer, but I'm ignorant of colour head settings for grade 1, 2, 3, 4, equivalents. It's an LPL enlarger.
Here is Ilford's data sheet with that information. The LPL enlarger is listed under the Kodak heading.
