180 grams A4 inkjet paper sheets‚ hand painted on with mainly drawing inks. Also used: bistre and graphite. The paper consists of 3 layers: an emulsion‚ a plastic coating and a paper under layer. The emulsion swells up when in contact with the inks and will slowly dry up. This process is repeated with each thin layer of ink that is added. The plastic coating has a fine grid in which the dried up inks and emulsion will set. Inks and emulsion can be manipulated into the grid. The painted area of the
