I recently bought a Philips pcs130 enlarger with the pcs150 tri-one colour unit. I know it's possible to select different contrast grades with the Yellow and Magenta settings on the colour unit (for VC paper), but I don't know which combination of values I can use.... The scales on the colour unit are in Agfa and Kodak density values.
Instead of experimenting randomly with different settings, I hope someone can give me a starting point.

Thanks,
Tim

Go to the website for the paper you are using, and you should be able to find a conversion table on the data sheet for the paper.

Thanks for the advice!
