Should adjusting contast effect color in a b&w print

Hello,

I am printing a B&W image. I printed two versions, the difference being that on the second print I added a radial mask with a curve adjustment bringing up the midtones at the center of the image.

What I noticed is that the image without the adjustment printed with a slight color shift, looks like magenta. I only noticed it after printing the second print with the curves adjustment. My question is, could adjustments effecting contrast (or any anything else) create a shift in color like you might get by adjusting the color sliders on the B&W tool and if yes, why?

I did not attach the images because it was only noticeable on the print. My print settings were the same for each print.

Thank you.

Colors appearing in a printed image (color or b&w) is a rather complex subject. You may be in for quite a read in books and on-line resources. My first tip would be to make sure you know what software manages printed color in your system. The application (C1?) or the printer/printer-driver or do they fight over it?

I have often turned to Keith Cooper's "Northern Light Images" myself, and you may begin with the article http://www.northlight-images.co.uk/printing-greyscale-images-and-removing-unwanted-colour-tints/

You will find a b&w test image and links to more articles here: http://www.northlight-images.co.uk/digital-black-and-white-photography/

Thanks, I’ll have a look at those articles and Keith’s site.
