One
way I was hoping to develop the original laser engraving, was to engrave the
image as it appeared on the computer screen before it was transferred to the
laser engraving machine. This proved to be quite a difficult thing to do,
because as a team we had only produced work that was laser cut which was relatively
quick or laser engraved images which took considerably longer to produce a sample.
For example my small sample on fabric took 28 minutes to produce. This would
prove to be very costly if I were to produce a larger piece. When the laser
cuts an image it will go around all the individual shapes cutting them out, this
is a relatively quick process. When laser engraving, the laser moves in a side
to side action and gradually create the image required taking conceivably more
time. I was looking to produce an image that was a continuous line engraved
deep enough into a substrate that could be use to produce prints from. After some
discussion and experimenting we came up with a compromise which allowed us to
produce what you see now. We changed the thickness of the substrate and set the
parameters of the laser machine so that the laser did not cut all the way
through the substrate. I feel that what you see is quite interesting in terms
of the preciseness of the cut giving clean and defined shapes. My intention was
to produce print from this image however we need to experiment further as the
line need to be thicker and deeper to allow for loss of image from the printing
process.
