Pros & Cons of Solar Plate
Advantages:
Solar plates print beautifully and can print any mark made on paper. This
gives it a clear edge over traditional methods (e.g. aquatint, mezzotint,
engraving, etching, stipple and even drypoint). Solar plate can not only
create traditional intaglio and relief effects, but also many other effects
not easy to achieve using traditional methods.
Solar plates are durable, capable of pulling far more prints than most fine
art printmakers will want. (In the commercial printing industry photopolymer
plates may run off a million or more copies.)
Solar plates give an attractive plate tone.
Solar plates avoid use of unhealthy chemicals and toxic materials used in
traditional acid etching, e.g. nitric acid, rosin, ashphaltum and various
solvents. Manufacturers state that the wash out water from solar plate making
poses no danger to health or the environment. See the health
& safety page for more advice.
Unlike other photo processes used by printmakers (e.g. photo-etching), solar
plate needs no darkroom.
No prior knowledge of plate-making processes is required. Virtual beginners
can achieve much the same results as experienced printmakers. (NB But
participants in the project must have experience of using the etching press
safely and of inking relief and intaglio plates.)
Solar plate preparation is quicker than many traditional methods, notably
etching.
Very little additional equipment is needed and this can be easily
constructed at home, e.g. a contact frame.
Printmakers using solar plate are in the vanguard of a new fine art
printmaking technique that is likely to become as established a method as
woodcut or copper plate etching.
Solar plate can be used to transfer text, photographs and other images on to
archival paper. The hand-printed image has an intangible allure. Ink sits on
the paper surface in a way that is totally different from laser prints or
photocopies.
Disadvantages:
- With solar plate, you have only one chance to expose the photopolymer. So,
make sure that you get the transparency image right before exposure of the
photopolymer. If you don’t, you’ll have to throw away the solar plate and
start again with a new or reworked film and a new (expensive) solar plate.
- Any imperfections in your transparency (e.g. scratches, watermarks, etc)
will be faithfully reproduced on the solar plate. Hairs, dust and other
blemishes trapped in the contact frame will similarly appear on your solar
plate and on the resulting prints.
- Solar plate is relatively expensive, as are the specialist transparency
films. Overall the cost of solar plate is probably no greater than copper
plate etching.
- Solar plate is difficult to obtain. Current UK suppliers are wholesalers to the
commercial printing industry. They are often reluctant to sell individual
plates to fine art printmakers and want orders worth several hundred £.
