Definitions

  • the exposed areas of the gelatin layers are oleaginous ink-receptive and the plate may be immediately placed on a printing press.
  • Glacial acetic acid ml. Benzotriazole (1 51100 ml, of alcohol) 100 ml. 1 molar potassium citrate (aqueous) 100 ml. 3 molar potassium bromide (aqueous) 50 ml. 3 molar copper (ll) nitrate trihydrate 25 m1. 1 molar iron ("1) nitrate monohydrate 25 m1. Triphenyl guanidine (l gJlOO ml. olalcohol) 50 ml. Water to make L000 ml.
  • EXAMPLE XXI An element prepared as in example X was exposed on a phototypesetting machine having a cathode-ray tube readout operated under the condition ordinarily used for exposing phototypesetting film. The exposed sample was developed for 30 seconds in a suitable developing machine filled with the developer of example I and activated for 8 seconds in a suitable processing machine filled with the activator of example 1K. The sample was then placed on the office duplicating machine of example I, swabbed with the fountain solution of example I, inked with lithographic ink and used to print several thousand offset copies of good quality on white bond paper.
