Article I wrote for www.portal-pelion.cz: The current era is characterised by, among other things, the flooding of the market with cheap laser marking, engraving and cutting machines. Even households have access to devices that are very similar to plotters (coordinate recorders), which use a laser beam instead of a pencil or pen. The laser burns a mark, relief or cuts into the material. Perhaps such a device will also find application in the much cheaper creation of tactile graphics using special papers (commonly referred to as microcapsule paper).
