Description
Technical field
The present invention relates to a kind of laser printer, particularly a kind of medical film laser printer.
Background technology
Medical film is a kind of material recording the armarium diagnostic images such as CT, nuclear-magnetism, DR, is blue without the medical film used, in black after overexposure or printing.From image-forming principle, medical film is divided into two big classes, one class is traditional dry type medical film (chemical imaging), dry type medical film uses the chemical raw material such as silver halide, developer to make, through the luminous or camera contact of heating, film produces chemical reaction and forms image, imaging process there is volatile material shed, environment and medical personnel are had certain harm；Another kind of is to print class medical film (physics imaging), uses normal printer to print, does not produce harmful gas and volatile material, environmental-protecting performance is better than dry type medical film.But using normal printer reflective to be affected by medical film is blue, the image entirety printed is the most blue, and blackness does not reaches diagnosis requirement.
The most any brand of laser printer and any model, core component all comprises carbon dust and toner cartridge.Carbon dust is micron-sized colored particle, is divided into and comprises four groups of colors and respectively cyan, carmetta, yellow, black, and is transferred to medical film by toner cartridge and forms image.Owing to medical film is originally as blueness, by light refractive effect, the film printed is visually overall blue.Find after experiment repeatedly for this, after changing the part or all of color in C (blue or green), M (fuchsin), Y (yellow) powder in printer powder cabin into K (black) powder, light hiding rare can be improved, reduce the light refraction caused because of blue medical film.Meanwhile, in order to prevent from changing after carbon dust because of black carbon powder excessive concentration, cause the problem that part gray-scale is lost, transition is stiff, need the blackness of each black carbon powder is controlled, it is ensured that the integrity of 256 GTGs.

Embodiment 7: medical film laser printer described in present patent application is as follows compared to the contrast test data of Conventional color printer:
Test equipment: Xerox 4475 Printing machine and RPO-310 transmission-type Density Measuring Instrument；
Test condition: use the color bitmap of 5 grades of different blackness of Photoshop software development.Use the original-pack carbon dust of printer (CMYK) and improved scheme to be printed upon on blue medical film respectively, measure density value with RPO-310.Specifically it is shown in Table 1:
Table 1
Data from table 1 can draw, the black density of scheme one is minimum, this is because C (cyan), M (fuchsin), Y (yellow) are not enough to the hiding rare of light, adding the reflective refraction of blue medical film, visually image entirety indigo plant partially causes black density to decline.It is known that, black absorption light also has excellent covering performance, therefore powdered black ink is set prints by whole or optional two groups or three groups of cartridges, i.e. scheme two, scheme three, along with the increase of black carbon powder, the blueness of medical film is reflective effectively can be absorbed by black carbon powder, and black density value is greatly improved, when the highest black density value reaches more than 2.0, the partially blue problem of visual image thoroughly eliminates.
Another discovery, use color 231F20 (C=0, M=0, Y=0, K=100) it is standard value, calculate the density multiple between its allochromatic colour number and standard value, when printing low blackness image (color number 808285 and color number 939598), the multiple of scheme one and scheme three is interval at 0.2-0.3, and scheme is second more than 0.4 times, visible scheme two scheme blackness value when printing light-colored image (low black) is higher, and color range transitionality is the softest.It is thus desirable to the blackness between the black carbon powder in each powder box is carried out conservative control, meet the requirement that blackness gradual change is excessive.
Through experiment and Data Comparison repeatedly, (i.e. in C powder box 3, the blackness value of powdered black ink is 1.1 to scheme three, in M powder box 4, the blackness value of powdered black ink is 1.1, in Y powder box 5, the blackness value of powdered black ink is 1.3, in KET box 6, the blackness value of powdered black ink is 1.5) collocation of powdered black ink is optimal collocation, can reach the optimum efficiency that blue medical film prints, i.e. meet the demand of color-grading, color transition is optimal.
Specific experiment method is as follows:
Using Photoshop software to open test Fig. 2, in Fig. 2, word SK Gaming one has 11 layers of color range from deep to shallow.Word can be seen clearly with naked eyes to be as the criterion, visible 1-8 layer (note: due to the reason of computer monitor aberration on computer monitor, the visible number of plies is had any different on different computers, and the visible number of plies of the present invention is as a example by author's computer), 9-11 layer is the most visible.Use Fuji-Xerox 4475 Printing machine to be printed upon on medical film by test figure, then observe the color range number of plies on film.Under normal circumstances, the image after printing the same with computer picture should can only identify 1-8 layer.As naked eyes can recognize 9-11 tomographic image, illustrating that color is partially deep, as identified, layer 1-7 is interval, then explanation color scheme is the lightest, has the situation that color range is lost.Specific experiment the results are shown in Table 2:
Table 2
As seen from Table 2, scheme one, scheme three, scheme four color range reducing degree the most similar to computer original copy, preferably for the printing of medical film, in conjunction with the black density measurement result of table one, preferred version three be first-selection modification scheme.
Medical film laser printer of the present invention can carry out Late reformation acquisition with most of laser printers of the prior art.Medical film laser printer the most of the present invention contains four groups of cartridges and four groups of toner cartridges, and certainly after reasonably improving, arranging of two groups of its cartridges more than two of cartridge all can be by obtaining the enforcement of scheme after the optimization of present patent application.
It is to be understood that: the detailed description although the present invention is contrasted by the present embodiment; but these explanations, simply simple declaration rather than the limitation of the present invention to the present invention; any without departing from the innovation and creation in true spirit, each fall within protection scope of the present invention.
