Lith printing as you are using it is a slang term. The word Lith is a common abbreviation for Lithography and therefore its slang use is likely to be misinterpreted. I know Tim Rudman used "Lith" in the title of his book but the word Lith already had a definition. I call my prints done in the "Lith" process "Infectious Development Silver Gelatin Print"
I can hear the questions now: "just how infectious is this print?" "Is there a vaccine for this?"
