will be the liquid supplied to the slot 28 preferably the liquid is supplied to the slot 28 through the opening 29 at a pressure incrementially greater than the pressure of ink in the chambers or compartments between the sealing assemblies 23 also the amount of liquid removed through the opening 30 is slightly less than that introduced through the opening 29 so that there is a slight axial flow of liquid out of the slot 28 thus there is some leakage of the seal liquid into the ink this is especially advantageous because it not only creates a positive separation and prevents mixing of inks across the seal but also aids in providing a portion of the makeup solvent to compensate for evaporation a further advantage is that the continual but minor flow of liquid axially against the surface of the anilox roll serves to minimize dry up of any ink which may seep or spray onto the anilox roll surface in the portion thereof passing under the sealing assembly this could be especially disadvantageous the drying of ink in the anilox cells when the seals might later be removed and printing is required where seals had been located one particular useful application of the invention is in connection with the printing of newspapers.
