A method to improve the image of a printed barcode by enhancing coverage of the print pixels within solid printed areas to improve the print uniformity and decrease the graininess of the typical ink jet printing by dissolving a small percentage of the colorant and distributing more uniformly. The parameter improved by the invention is the graininess or uniformity of coverage. The contrast ratio within barcode data elements can be also improved without causing unwanted image bleed into unintended areas. Hence, the printed barcode will contain more clearly defined printed and non printed areas to enable the barcode to be accurately read. The invention prevents also unwanted bleeding in areas where it could lower the quality of the printed material by avoiding application of enhanced coverage facilitators when desired white space is identified within a minimum distance.

A washing machine includes: a cabinet forming an external appearance and having an open upper portion; a reservoir hanging within the cabinet and allowing washing water to be put therein; a washing tub rotatably disposed within the reservoir and accommodating the laundry; and a spray nozzle spraying washing water into the washing tub such that one boundary of sprayed washing machine reaches a side wall of the washing tub and the other boundary of the sprayed washing water reaches the bottom of the washing tub, wherein the spray nozzle includes: a tube part forming a passage along which washing water is introduced; and a spray part connected with the tube part to spray washing water and disposed such that a spray face against which washing water discharged from the tube part splashes is bent at a certain angle with respect to a discharge direction of the tube part. The laundry can be effectively wet by increasing a spray range of washing water.

A method for washing laundry in a washing machine utilizes a washing tub external to a rotatable washing drum. The method includes: • providing a quantity of detergent; • providing a first quantity of water to form with the detergent a quantity of washing solution; • introducing the washing solution into the tub; • recirculating the washing solution inside the tub by means of recirculation means until the washing solution is absorbed by the loaded laundry inside the drum and the level of the washing solution is below the drum; • activating heating means for heating the wetted loaded laundry inside the drum; • deactivating the heating means and maintaining the heated wetted loaded laundry inside the drum for a predetermined dry maintenance time; • supplying a second quantity of water in the tub; • rotating the drum; and • rinsing the loaded laundry by means of drum rotations and by means of liquid drainage from the tub.
