The development of multicolor printing

On the basis of the technological changes in single and multicolor printing, we would like to present
Dr. Hell's inventive step.

The article "Development of Multicolor Printing" illustrates the unimaginable effort that was required in the time of lithography (around 1800) even to the beginnings of offset and gravure printing, for the reproduction of image and text.  Only with the inventions and the devices of Dr. Hell this effort could be gradually reduced from 1950.

Further articles will explain the significance of these inventions from 1950 to 1998 in detail. (German)
