The course is intended for complete beginners to aluminium etching though familiarity with printmaking techniques in general would be useful. This course will provide an introduction to the basic processes of creating and printing from an aluminium etching plate. Aluminium etching is considered a somewhat safer and simpler form of etching as no strong mordants or etching agents (such as acids) are required.
Aluminium is a soft, easily marked metal which can be etched with a variety of chemicals, in particular, saline copper sulphate which is the etchant to be used in this course. An image is created upon the plate by a process of masking out parts of the metal and then etching the exposed lines and areas with the etching solution. Direct marking of the plate is also possible. Printing is undertaken in a similar manner to other etching plates.
Over the two days of the workshop we will cover:
Safety considerations and the basic principles of aluminium etching.
Materials: plates, ‘etching agents’ and determining etch times.
Inking and printing the plate and other possibilities.
By the end of the course you should have a good understanding of the main processes involved in making a printing plate using aluminium etching.
You will need notepad & pencils and an apron/smock/shirt you’re happy to get ink on. More detailed notes will be provided once a booking is confirmed.
Equipment and materials including printing plates, etching agents, paper and inks are included in the cost.
