Date/Time: 8 Jun 2017 - 9 Jun 2017
Tutor(s): Hildegard Homburger
In this two day course the most important photomechanical techniques – relief, intaglio, planographic, screen and digital prints – will be examined.
These different techniques (both for artistic and reproduction contexts) will be examined by studying original prints under magnification and the observing the distinctive characteristics of each technique by close inspection of these original prints.
With the introduction of photography in the 19th century, printers no longer had to transfer the image manually onto the printing surface, but were able to transfer the image by sensitizing the printing surface and exposing it to light, through a negative or positive film (depending on the printing technique).
With computer technology, negative or positive film is often no longer necessary. The image is transformed into dots by computer and the image is transferred to the printing surface by light exposure in the machine.
Since their invention, photomechanical printing techniques have continued to develop further. There are many similar variations of the same technique, each named differently by its inventor. This can be very confusing in the process of identification and it is intended that this short course will provide an opportunity to look at a great number and variety of original prints under magnification and to develop skills in the identification of their techniques. There will also be the opportunity to compare photomechanical with manual prints provided by the tutor.
