Rawlins ca. 1904. A sheet of paper is coated with a thin layer of gelatin and sensitized with bichromate, dried in the dark and exposed under a negative. Exposure hardens the gelatin in the shadow areas and partially in mid-tones. Soaking in water subsequently removes sensitizer and causes the mid-tone and highlight areas to absorb moisture. Oil based inks are repelled in these areas, and remain to a greater or lesser degree in others. The plate is then allowed to dry or is transfer-printed to another sheet, then re-inked for more prints. ]]></note></mads>
