Digital BW, The Print

May I humbly refer you to my personal art website re "carbon" printing equipment and technique under "Traditional --" at www.jvee.com , not my commercial printing site www.jveegraphics.com.   I am a pretty ancient gelatin pigment printer.    J Vee

They are each 22"x30" in size and have been coated without washing the paper (in other words, I coated a dry sheet of paper, rather than wet, as I did until September). I am using four different formulations for the coating.

Magnani Pescia is a real sponge and where I live the humidity is always in the 70%-80% range. The dry coating takes about half that time. Molding is almost guaranteed in this environment and it requires the addition of an anti-bacterial in the coating. Although there are many such products on the market, my difficulty is to find an archival product, possibly all natural, to be consistent with the archivalness other stuff in the mix. At the moment I am using thymol, a natural disinfectant. It has been quite effective for the last two years. However, its smell last for long time and I found out that it does not protect the print if that is stored in a very humid environment and in the dark. Other product I am still testing are: cloves oil, salicylic acid and methyl-paraben. Most of my techniques are covered in my web site (although it requires a substantial update, including two new portfolios I have been working on since almost two years).
