[INTRODUCTION]
Printing from stone is a branch of a new process, different in fundamental principle from all others, namely, the chemical process.
Heretofore there have been two leading printing processes for manifolding writings and drawings, one working with characters in relief, the other with sunken characters.
Of the first kind is the ordinary book-printing, in which the characters are made of metal or wood in such form that only those lines and points are elevated that are to take color, everything else being depressed. The wooden forms for cotton-printing are made thus also.
