Abstract: A printing apparatus in which metered amounts of an ink and a diluting solution are mixed and the resulting mixed liquid is ejected to a recording medium for printing. Specifically, the ink and the dilution liquid at least containing a water-soluble organic solvent are mixed together in respective metered amounts and the resulting liquid mixture is ejected to the recording medium. The water-soluble organic solvent desirably contains the aliphatic monohydric alcohol, a polyhydric alcohol or its derivatives. The dilution liquid may contain a non-water-soluble organic solvent or a dispersion medium composed of water and a non-water-soluble resin. An OH-group containing resin and a cross-linking agent are desirably contained in the non-water-soluble resin. Ink fixing properties for a picture recorded by discharging the liquid mixture of the ink and the dilution liquid may be improved, while suppression of bleeding in the picture and improved discharging stability are also achieved.

Abstract: Hydrophobic colloid charged so as to have positive zeta potential when the pH of ink (2) is in the range of 4 to 6 is contained in ink (2). Thus, dissolution of silicon, silicon compounds, etc. into ink (2) from circuit board (44) composed of silicon wafer, etc. can be inhibited. Further, deposition of silicon, silicon compounds, etc. having been dissolved in ink (2) on heating resistor (48) so as to cause kogation or deposition thereof in ink channel (42) or nozzle (45a) so as to cause clogging leading to ink ejection failure can be prevented.

Abstract: A thermal transfer recording medium comprises a substrate and an ink layer formed on the substrate. The ink layer comprises a first dye having a light absorption peak which has a maximum absorption wavelength, lambda max, of 420 to 500 nm and a half-value width of at least 100 nm, and a second dye having a light absorption peak which has a maximum absorption wavelength, lambda max, of 570 to 650 nm and a half-value width of at least 100 nm. The ink layer may further comprise a third dye having a light absorption peak whose maximum absorption wavelength, lambda max, of 500 to 550 nm and/or a fourth dye having a light absorption peak whose maximum absorption wavelength, lambda max, of 620 to 680 nm. When a density-graded indication is made using the thermal transfer recording medium, there can be obtained images whose black hue shift is small in all the density range.

Abstract: A thermal transfer recording process comprises heating an ink ribbon having a dye-containing ink layer on a substrate in an imagewise pattern to thermally transfer the ink of the imagewise pattern to a dye-receiving layer of a printing sheet made of a cellulose ester, and subjecting the transferred image to thermal treatment preferably between 60 DEG and 200 DEG C. By the thermal treatment, the image is improved in light fastness and resistance to grease and plasticizers. The cellulose ester may be mixed with up to 50% of another polymer such as polyester or vinyl chloride - vinyl acetate copolymer.

Abstract: An ink jet printer (100) ejects ink drops from a plurality of nozzles and drops the ink drops on paper P, thus recording information including a character and/or an image in the form of dots based on the ink drops. The ink jet printer (100) has a line head (120) having a driving element for ejecting ink drops from the nozzles. The ink jet printer (100) causes the line head (120) to scan the same portion on the paper P only once in one print and drives the line head (120) to modulate the diameter of a dot by the number of ink drops, using one or a plurality of ink drops for forming one dot.
