    This post is similar to my last one about "Homemade dektol". Answers
    found there are very interesting and rich of suggestion. The fact is
    always the same, but a new post is better to obtain more specific
    answers.

    The matter is: how to obtain "line art" negatives starting from Kodak
    TP at 100 ISO treated with Neutol? In practice, which diluition of
    Neutol is better? How many minutes of treatment?

    Thanks in advance to all experts I've found here!

    I mean Neutol NE, for paper. I want to use it because I've some at
    home... and as said to obtain line art negative.

  4. Kodak data sheet P-225 on Technical Pan film gives the
    following for development in Kodak Dektol. Neutol or other
    active print developers should be about the same:
    Time: 3 minutes at 68F (20C) in a small tank with agitation
    every 30 seconds. Dilution is not given so presumably this
    is for full strength developer.
    Exposure Index is 200
    Contrast is given as a CI of 2.50 with center of curve gamma
    value of 3.60
    This is suitable for line work although not as high a
    contrast as a lith film in lith developer would yield.

    As written privately to Mr. Knoppow, I've found for Agfa Ortho 25 ISO
    to develop it with Neutol NE 1+7 for 3 mins. Applying the general rule
    (approximated) that says "dubling EI the develop time is 1.41 times
    (sqrt(2))" I've thought for TP at 100 ISO to use Neutol NE 1+4 for 4
    mins. Is this completely silly or not?

    Bye
