Thank you Richard, Ryuji and Jim for the information. I will try to find the papers that Ryuji mentioned to satisfy my curiosity, but for now, I think I will stay with the process that I am comfortable with. As I read your comments, the advantages of all alkaline process seem to be relatively minor. John, I am somewhat relieved that the MCS is not photochemical-specific. I have never experienced any reactions from the standard B&W chemicals such a Dektol, acetic acid or Kodak Fixer, however I will probably start using nitrile gloves dedicated to each tray for print processing and see how it works. - Andrew. ============================================================================================================To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
