SCIENCE IN THE INDUSTRIAL WORLD 



there is still the enormous field of color printing, that 

 is now only in its infancy. "The demand for printed 

 matter seems to increase with the ability to furnish it," 

 says a recent writer, a and much attention is now being 

 directed to the subject of color printing on the rotary 

 system. From present appearances and from the en- 

 terprise displayed by the publisher, the artist, and the 

 press-maker, it would seem as though the day is not far 

 distant when this subject alone would furnish matter 

 for a new chapter in the history of the printing-press." 



And, indeed, for anything but the very finest kind of 

 color printing, the matter for this chapter is already 

 in hand. In a later chapter in this volume this subject 

 will be again taken up in detail with particular reference 

 to the scientific aspects of the color combinations; but, 

 as will be seen there, the matter of perfection is really 

 "up to" the presses, and they are making strides that 

 are certain shortly to close the gap. 



"The last three or four years have witnessed an im- 

 mense advance in the art of color printing. The maga- 

 zine without an elaborate color cover, or perhaps colored 

 illustrations, is now an exception, whereas it was the 

 reverse not long ago. After satisfactory experiments 

 it was ascertained that, with the inks properly prepared, 

 and suitable plates to print from, colors could be 

 printed almost simultaneously upon the paper, without 

 mingling; in short, that the supposed necessity, in 

 much of the work done, of drying the sheets after the 

 impression of each color on the paper, was not necessary 

 for the production of a good quality of printing. Fur- 

 ther experiments also proved the mechanical possibility
