The third process, lithography, might al- most claim a place among modern methods, had our line been drawn but a few years further back. It differs entirely from either of the processes above described. It may be said to rely for its success on the mutual antipathy of grease and water. A wet stone will not hold greasy matter, and a greasy stone will not hold water. If therefore a design be drawn in greasy ink upon a properly smoothed and prepared stone, and the stone, after a very slight “etching” with an acid solution, be then wetted, the inked parts of the stone will not take up water, and the wet parts of the stone will not take up ink. The stone may therefore be rolled upon with a suitable roller charged with ink, and ink will only be transferred to the lines of the design, the wetted parts of the stone remaining clean. The design may then be printed off upon paper by a suitable press. Further, the design, in- stead of being drawn direct upon the stone.
