The a plurality of looks of transfer printing district is to the heat transfer type printer and the Method of printing thereof of imaging media
Technical field
The present invention relates to a kind of with heat transfer type printer prints method of patterning, relate in particular to a kind of with a plurality of looks of heat transfer type printer prints district to the method for imaging media with print pattern.
Background technology
Hot transfer printing printing technique (Thermal transfer printing technology) be in the initial stage eighties by Japanese fuji related company Fujicopian Co., Ltd. the technology that at first begins one's study, then by International Imaging Materials, Inc. (IIMAK), this patented technology is transferred the research institution of the U.S., continue development.Commercial heat transfer type printer the earliest appears at 1986, and up to 2000, thermal transfer printing system faced many improvement and revolution thereafter.The colour print demand is ardent day by day, adds that the rate of holding of digital still camera continues significantly to increase, and except company's row number has demand, the general common people also gradually need to export photochrome.Yet because hot spot can produce thermal diffusion effect, in general the resolution of early stage hot transfer printing is not fine.
The general employed colour band of heat transfer type printer is the transparency celluloid paper (transparent celluloid paper) of a kind of content of wax and dyestuff.When printing, heat-transferring head can heat the dyestuff on the colour band, and seeing through the variations in temperature dyestuff can temporarily liquefy and be moved on on the imaging media (as paper) by colour band, and then the dyestuff cooling promptly is fixed on and presents image on the imaging media.See also Fig. 1, Fig. 1 is the colored colour band schematic diagram in the known hot transfer process.Among Fig. 1; many group looks district 141 is arranged continuously on the colored colour band 12; 142 etc.; in each look district the dyes in different colors district is arranged; as having in the look district 141: yellow (Yellow) dye area 1Y1, magenta (Magenta) dye area 1M1, cyan (Cyan) dye area 1C1 and transparency protected district (Overcoating) 1O1.Known heat transfer type printer can heat the different colours dye area and the transparency protected district in one group of look district on the colored colour band 12 in regular turn with heat-transferring head when colour print, the dye well protective clear layer on it is transferred on the imaging media.With look district 141 is example; heat-transferring head is from look district starting point 161; heating transfer weld district 1Y1, magenta dye district 1M1 and cyan dye district 1C1 in regular turn; heat transparency protected district 1O1 on the colour band again to cover protective clear layer to the figure of output, hot transfer process is to 181 end of look end of extent point.The generalized section as a result of the hot transfer technique of the known for this reason colour of Fig. 2, M1 is an imaging media, and LY1, LM1 and LC1 are respectively weld layer, magenta dye layer and cyan dye layer, and LO1 is a protective clear layer.Please consult Fig. 3 again, Fig. 3 is the monochromatic colour band schematic diagram in the known hot transfer process.Among Fig. 3, many group looks district 341,342 etc. is arranged on the monochromatic colour band 32 continuously, a black (Black) dye area and a transparency protected district are arranged, in each look district as black dyes district 3K1 and transparency protected district 3O1 are arranged in the look district 341.Known heat transfer type printer can heat the black dyes district and the transparency protected district in one group of look district on the monochromatic colour band 32 in regular turn with heat-transferring head when monochrome is printed, the dye well protective clear layer on it is transferred on the imaging media.With look district 341 is example, and heat-transferring head is from look district starting point 361, and first heating transfer black dyes district 3K1 heats transparency protected district 3O1 on the colour band again to cover protective clear layer to the figure of output, and hot transfer process is to 381 end of look end of extent point.The generalized section as a result of the hot transfer technique of the known for this reason monochrome of Fig. 4, M3 is an imaging media, and LK3 is the black dyes layer, and LO3 is a protective clear layer.
Because the quantity that the time that heat-transferring head can be controlled heating decides dyestuff to shift, therefore, compare with ink-jet or other printing types, the color range that the heat transfer type printer can determine is more also more accurate, color is fresh and alive, well arranged, reappears the changeable complexion and the natural primary color of each color range, can reach the performance of continuous color range, compare with half color range of ink-jet, more near the photograph quality.For instance, when a GTG produces, from black in vain, continuously the printer of color range can demonstrate continuous full-color GTG when printing, and half color range device, as ink-jet printer, utilization is passed look technology (Dithering) and is arranged in very fine and closely woven point and comes along analog image, can't reach the quality of continuous color range.In other words, ink-jet printer is that all stains closely are connected on the other pixel analog image to mix of white point, and to reach the naked coloured image of being seen of looking of human eye, its print quality can't be compared with continuous color range, especially after image was amplified, its quality discrepancy is upright to be seen.On preserving, because the output device matcoveredn of heat transfer type printer, it occupies bigger advantage than other technologies in the performance of waterproof, antiultraviolet and anti-fingerprint.Although so the resolution of thermal transfer printer is not high comparatively speaking, the texture that is presented is far beyond other general printer height.
Yet, because the heat transfer type printer is by the dyestuff on the heat-transferring head heating colour band, by the variations in temperature dyestuff its temporary transient liquefaction is moved on on the paper by colour band, cooling is fixed on the imaging media with output pattern again, and the material of colour band (being transparency celluloid paper (celluloid paper) as common) can be out of shape and produce gauffer because of the overlong time of heating; So if the figure chroma of desire output is higher or color saturation is higher, dyestuff can form on imaging media as the effect as the ripples (ripple).For fear of this distortion phenomenon, it is long that known heat transfer type printer can not make heat-transferring head continue heat time heating time, also therefore can't print the higher or figure that color saturation is higher of chroma, and the color dynamic range of output also thereby wide inadequately.
Print shortcomings such as the not enough and colour saturation dynamic range of color saturation is wide inadequately in order to overcome, the past is mostly towards lifting colour band quality direction and effort, but because of its technical threshold height, improves very limited.
Summary of the invention
Therefore main purpose of the present invention is to provide a kind of when the heat transfer type printer prints, a plurality of looks of transfer printing district to the image forming material with color saturation that increases figure and the Method of printing that enlarges the colour saturation dynamic range, to improve the problems referred to above.
