    Black and White prints can be made directly from colour
    digital files although the results are often unsatisfactory
    unless the file is first converted to greyscale. We would
    therefore recommend colour files be converted to
    Greyscale, prior to printing. The smaller files made by
    discarding the colour information are also much quicker to
    RIP and write. There is another advantage to doing this,
    as some colour originals printed straight to Black & White
    do not make suitable or interesting images without some
    adjustment to their contrast or density.

    Above statement comes from attached ilford paper. If we would print bw negatives on panchro bw papers , what is the point of making panchro bw paper ? Am I missing something ?

    They are not referring to negatives. They are talking about files.

    I don't know, as I don't do any digital. You should probably ask at DPUG.

    If you think about why we might use colour contrast filters in B+W photography you will understand why colour negative to B+W may not come out as expected.

    The papers mentioned here are designed for tri-color laser system.

    Thank you Vpooler. Yes , Prof.Pixel warned as they made to printed under RGB laser systems not white light. Its better to leave these panchro papers at their place and switch to ortho papers.

    Now the question , how we can improve the bw print with colored , stain colored, negative ? Can we paint the negative , I bet silk dyes works or can we digital manipulate the masks and color zones referencing the spectrum.
    I will find a widely available paper and continue.

    Well, if the negative is stained and affects contrast, you could probably just put a filter with exactly the opposite effect to use. Determine the shift and correct accordingly. And I see why not to do local contrast masks. People do that, I am sure.
