Concrete implementation content

Please refer to Fig. 2, Fig. 2 is that the present invention is the schematic diagram of the digital photo 20 that produced after the heat rotary type printhead prints.Photograph 20 comprises that one prints media (print medium) 22, and media 22 is that the dyestuff (printing dye) that can make the heat rotary type printer covers thereon.After dyestuff being printed on the upper surface 28 of media 22 when printer, a protective layer 24 just can cover upper surface 28 and be used for protecting dyestuff to avoid the influence that moisture or other can cause the factor that worsens.Protective layer 24 can distribute equably one in fact the thin layer of same thickness make photograph 20 that the polishing of smooth formula be arranged so that protection to be provided.Method of the present invention can be distinguished into protective layer 24 two-dimensional array 26, and handles on the array 26 protective layer of at least two different-thickness in the different units (pixel) according to light less type polishing pattern.Note that array 26 and unit wherein are not physical entity.In addition, for ease of explanation, the unit size of the array 26 of Fig. 2 is painstakingly amplified.

Please refer to Fig. 3, Fig. 3 is the dyestuff block that has protective layer on the heat rotary type printhead 30 heating colour bands 32, in order to shift protective layer to print media 22.Printhead 30, colour band 32 and print media 22 all can relative to each other move.As previously mentioned, printhead 30 can polish to give smooth formula on photograph 20 the protective layer heating in a period of time equably.According to preferred embodiment of the present invention, printhead 30 can utilize two protective layers on the different time cycle heating colour band 32, and is disposed the protective layer of two different-thickness.According to the configuration of Fig. 3, can obtain thicker protective layer configuration long heat time heating time.

Please refer to Fig. 4, Fig. 4 is the regional enlarged drawing of photograph 20.From the configuration of the two-dimensional array 26 of Fig. 2, printhead 30 utilizes the period 1 protective layer configuration that heat time heating time form different thickness different with a second round respectively.The long period 1 can form thicker protective layer zone, then can form thin protective layer zone short second round.The design of heat rotary type printhead 30 or other heat rotary type printheads can utilize the different heats that adds to be poised for battle the heating of row Unit 26, and this is as heating coloured dye to print off the method for image pixel.With Fig. 4 is example; an one thin protective layer district 40 and a thick protective layer district 42 are arranged on the print media 20; these are thick, thin protection zones 42,40 all are the upper surfaces 28 that is distributed in media 22 arbitrarily, and preferable distribution is that thick, thin protection zone 42,40 can both be with 50% probability distribution in upper surface 28 certainly.The shape of thick, thin protection zone 42,40 can be square, yet this also decides according to the design of printhead 30.In the practical application, the shape of thick, thin protection zone 42,40 comprises other shape, is not limited only to square.

The photograph 20 that utilizes method of the present invention to produce to have the light less type polishing and the light less type polishing of existing film are by contrast, because of the isoparametric difference of size and shape of period 1, second round, array Unit 26, make and compare the effect that goes even farther with traditional film.For instance, the specific rectangular cells of 150DPI random distribution supposes that its thickness unit ratio respectively is under 50%, 50% the situation, with 300DPI and thickness unit ratio be that 60%, 40% polishing effect is different.Other also can influence polishing effect as parameters such as the quality of photo paper and reflectance factors.No matter selected parameter value how, these modal shifts arbitrarily all must allow the people who sees photograph 20 not have problems existence such as any vision distortion, inhomogeneous reflection and unwanted flaw.Moreover the pitch on each unit (pitch) must be enough to show light less type polishing, not so the too poor pitch of the quality polishing effect that will can not obtain.

Period 1 and second round in this measure preferred embodiment are example.The method according to this invention if the cycle more than three of using produces corresponding protection zone thickness different more than three, promptly can obtain better polishing effect.Change an angle, among Fig. 1, the protruded object on the protective layer 14 of existing polishing film photograph 10 also can be regarded as being similar to and adopt a plurality of different time cycles.Certainly designer or user can look processing time of price, polishing of heat rotary type printer and the factors such as polishing quality that need consider the time cycle that will choose how much and length, if can bear higher cost and slower time-write interval, just can select for use the time cycle more than three to polish quality preferably with acquisition.

In the practical application, method of the present invention can be realized on existing heat rotary type printer, controls hardware such as this heat rotary type printer circuitry and microprocessor by appropriate software and can finish.

Compared with prior art, the present invention can use the heat rotary type printer just can be on the photograph of printing Generation light less type polishing, this so that photographers under the situation that need not use other developers, provide The convenient of another less expensive selected, and just can print off the digital photo with light less type polishing effect.
