Please provide us with vector based files which can be sent in a variety of formats, most commonly used files are dxf(2004), dwg(2004), illustrator and esp files.
If you want to raster engrave an image we can also work from jpeg, bitmap, tiff and png files.
It is important to make sure that your line weights of vector based drawings are nice and thin. We prefer to use a weight of 0.1mm for best results.
A semi-cut/score line will process much faster then a raster image. Therefore if the design can be achieved in score lines instead of using a pixelated image it will reduce the cost of the job.
