LPL Saunder 670 DXL color head

[Slobo]

Hello all,
Does anybody knows how to adjust this enlarger for B&W prints? A few years back I read somewhere on the web about this, but I lost the link. I remember that is all about filters settings.
Any help would be highly appreciated.

Thanks

Slobo

I believe the cc settings will depend on the paper and documented in each box.

Make a test strip. Keep notes. Want harder? Dial in M. Keep notes. Want softer? Dial in Y. Keep notes. Move in increments of 40 to see obvious impact. Keep notes. You'll be eyeballing it in no time, fairly obvious. Keep notes. Statistically, "normal" contrast on Ilford RC is about 40M, should be a good starting point. Keep notes. No hard numbers to stick to religiously--too much depends on filter age, type of light, batch of paper, chemicals mixed... Did I mention, keep notes.

Once you get the hang of it, exposure-invariant mixing of M and Y would be the next step, but it's only needed in rare scenarios.

By the way, keep notes.

Vilk is correct, however Ilford has made some suggestions in the data sheets for their variable contrast papers (listed under LPL, which falls under the general "Kodak" column): http://www.ilfordphoto.com/Webfiles/2010628932591755.pdf

Thank you guys. Yes I'll make test prints and keep notes, notes, notes..... I'll also read the Ilford's suggestion on this for sure. I didn't realize there is suggestion from Ilford on the subject.
