Recently I opened a large format printing shop doing things like posters, signs, Glecee prints and what not. Just to get an idea of the gear take your desktop 4 colour printer and add anywhere from 2 to 8 additional Colours and then stretch the printer upwards to 5 meters wide, and that is "wide Format" The other day I was replacing a couple of ink cartridges and I noticed the interesting shape of the cartridge.
the second pic is the bladder from the cartridge.
