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.
