The following is said to be a good recipe for making ink used with typewriter ribbons. It is from the English Mechanic:
Take petroleum of high melting point, melt it on a water bath, and incorporate, by constantly stirring, as much lampblack or dropblack as it will take up wiuthout becoming granular. If the petroleun remains in excess, the print will be liable to have a greasy outline; if the color is in excess, the print will not be clear. remove from the fire, and, while it is cooling, mix equal parts of petroleum, benzine, and rectified oil of turpentine, and in this dissolve the fatty ink, introduced in small portions under constant stirring. The solvent should be added in such proportions that the finished ink shall be of the consistency of fresh oil paint. Now wind the ribbon on a piece of cardboard, place on a table several layers of newspaper, then unwind the ribbon in such lengths as may be most convenient, and lay them smooth on the paper. Apply the ink by means of a soft brush, like a tooth brush, rubbing it well. Hardly any ink should remain on the surface. For colored inks use P[r]ussian blue, red lead, etc., especially te aniline colors. A specimen formula given is: Aniline black, ½ ounce; alcohol, 15 ounces; glycerine, 15 ounces. Dissolve the aniline in the alcohol, and add the glycerine, inking the ribbon as before.
