What reading level is Photogravure book?
To quickly assess the difficulty of the text, read a short excerpt:
For the most delicate ones. The action of each bath is cumulative, the 37 deg. Biting a little where the 42 deg. Had bitten, the 33 deg. Doing the same for those before it, besides taking care of itself, and the 30 deg. Attacking all more or less. During the biting with the 30 deg. Solution, it should be continued until the whites just turn color, and a minute beyond ; that is, the copper should begin to show a very little under the thickest and darkest film.
(Note that in the carbon resist the... shadows are transparent and the high lights are opaque. ) 36 PHOTOGRAVURE.
The length of the last biting very seldom is over two minutes. It is better to overbite your darks, and underbite your lights, if you vary any.
The amount of moisture in the air and the heat of the day influences the length of biting. In hot weather in summer it is very difficult to work the process, the walling wax being discarded and the copper (back and edges protected by varnish) placed in a porcelain tray, surrounded by ice-water and kept at 65 to 70 deg.
