[Concept]
Using inkjet technology enlargements photo machine.
The so-called dry-relative to traditional digital printing equipment (wet), both of which are professional photo output device, the difference is that the latter requires medication water rinse.
========================
[History]
---------------------
1.1976, the birth of the first inkjet printer
Inkjet printing technology as early as 1960, it was suggested, but 16 years after the first commercial inkjet printer before the birth of IBM original IBM4640 European the Swedish Lutheran industrial technology college professor Hertz and his colleagues developed , called continuous inkjet technology.
The so-called continuous ink jet is either stamped or non-stamped, are produced in a continuous manner droplets, then the non-stamped ink droplets recovered or dispersed.
But this technique is almost with droplets of ink dots printed onto the paper, the effect of the differential is conceivable, therefore no practical value in reality.
---------------------
2.1976, piezoelectric ink-point control technology came
With IBM4640 the same year, in the same year R & D development, the three Siemens technology pioneer researchers of Zoltan, Kyser and Sear piezoelectric ink dots control technical the (EPSON predecessor), and its successful use in the Seimens Pt-80, this section volume production printer in 1978 sales, to become a commercial value in the world's first inkjet printer.
---------------------
3.1994, the advent of the Micro Piezo print technology
In the 70s of the last century, Epson piezoelectric technology, after nearly 20 years, and finally succeeded in the Micro Piezo print technology used in the printer field product.
Micro-voltage technology, the basic principle is the many tiny piezoelectric ceramic is placed to the vicinity of the print head nozzles of an inkjet printer, using the ink in the voltage will occur under the action of deformation of principles, so that the ink ejection nozzle is formed in the surface of the output media pattern.
Epson smart drop transformation technology, natural color reproduction technology, ultra-fine ink droplets occupies an important position in the field of inkjet water output.
---------------------
4.2002, the advent of dry enlargements equipment
Epson Micro Piezo print technology, the emergence of qualitative leap in the perception of the screen, and even horses and photo effects. Then people began to imagine, the ability to perfect this technology and professional inkjet printing paper to engage in image photo output?
Finally, in the early 21st century, Noritsu teamed Epson in 2002, developed the world's first small dry minilab equipment - dDp421.
In order to the photo better save time, it uses a seven-color pigment ink. Followed by Noritsu equipment - dDp621 launched a same principle.
The advent of this new product, completely subvert the inertia of thinking of the people of traditional silver halide prints photo ink to print photos myth has become a reality.
The Snow Day dDp421/621 its smart mobile models, high-quality output effect, long storage time, fast output, environmental protection and energy saving advantages quickly occupy the international market and become the most hot products in the international market 2003.
---------------------
5.2008, the advent of high-precision dry minilab equipment
Pigment ink is a particle suspension solution, not clogging the print head, the milling process is very high, and the cost is also higher.
In order to meet the needs of the majority of printing companies, as the pioneer of a new dry minilab programs
In January 2008, Noritsu has introduced a new dye ink dry-Minilab - Noritsu D701.
D701 body is more compact than the previous years dDp421/621 is, The output length up to 36-inch. The new Noritsu research and development of four-color ink system (Y, M, C, B), and to improve the technology of the print head, a black spot showing a six Levels.
To ensure not only save time, but also to make the picture showing a gorgeous rich color, photo quality is completely beyond the silver halide photographs!
March 3, 2009, at the Las Vegas Convention Center, Noritsu introduced the Noritsu D703.
September 21, 2010 26, Noritsu photokina "in Cologne, Germany launched D1005HR.
Both devices accuracy, speed and enlargements increased further improved and enhanced.
========================
Technical principles
Using inkjet technology to high-volume output photo.
Current inkjet printers print head can be divided into: piezoelectric inkjet technology / thermal inkjet technology two kinds
Their principles are liquid inkjet principle.
Ink deterioration due to The thermal inkjet bad control the size of the black spots, but also easy to produce high temperature, generally used is a combination of continuous ink jet technology with piezo technology.
---------------------
1 [piezoelectric inkjet]
Many small piezoelectric ceramic is placed into the vicinity of the printing head of the inkjet printer, using the principle of the piezoelectric ceramic in the voltage under the action of deformation will occur, and this way the printer, can be reasonable structure and flexible to the control voltage by effectively control the droplet size and reconcile, which can achieve high print accuracy and better print results, due to the need for heating in inkjet, so the ink does not undergo chemical changes, the ink is not particularly high.
---------------------
2 [thermal inkjet]
Also called thermal bubble technique, and it is through the heated nozzle, so that the ink to produce bubbles, and then sprayed onto the surface of the print medium, when printing ink will sometimes occur in the high temperature heating of chemical changes, therefore, in the printed pattern and fonts will have some impact on the authenticity of the addition was because the ink is ejected by the bubble-like, so bad on the directionality and size of the ink particles to grasp the intensity, which also affected to a certain extent to the print effect.
Although the nozzles of the thermal inkjet technology to produce lower cost, but the electrode in the nozzle will be electrolysis and corrosion, and so generally do not have a very long service life.
---------------------
3 [continuous ink jet technology + piezo technology combine]
(1) before the ink-jet operation, the piezoelectric element under the control of the signal first slight contraction;
(2) The components have a larger extension of put the ink droplets launch the nozzle;
(3) instantaneous droplet soon exited the nozzle, the element will be carried contraction neatly contraction of the ink meniscus from the nozzle.
(4) Thus, the ink droplet meniscus to obtain the precise control of each ejected ink droplet has a perfect shape and correct the direction of flight.
Ensure accuracy at the same time, the use of the piezoelectric drive device to be a fixed pressure of the ink in the nozzle, so continuous ejection.
(5) for recording, the use of the vibration of the oscillator signal excitation jet ink droplets is generated, and the ink droplet size and spacing control.
(6) by the character generator, the print information from analog modulator control telegram charge control, the formation of charged and uncharged ink drops, and then to change the direction of flight of the ink droplets by the deflection electrodes, so that need to print of ink droplets flying paper generated characters / graphics record. Does not participate in the record ink droplets is recovered by conduit.
(7) of the deflection electrodes, and some systems using two pairs of mutually perpendicular deflection electrodes, the ink droplet print position for two-dimensional partial transformation; some systems using multidimensional control pair of deflection electrodes, i.e. multi-dimensional partial transformation.
(8) when the black point fell on the photographic paper surface, the ink-receiving layer of the photographic paper coating will be absorbed.
(9) ink droplets smaller print pictures more clearly.
If we move the ink in the primary colors were taken in different proportions, and then ejecting it to approximately the same point, then the approximate point can be displayed according to the different proportions of each primary color in a different color, which is inkjet The basic principle.
---------------------
Dry photographic processing machine, is generally used in the piezoelectric.
But because enlargements machine, so demanding print head technology requires high accuracy, continuous output, but also to wear durability.
Requirements for the ink is very high, not only to show the real bright colors, but also a high degree of fade resistance.
The paper feed technology is also very important. Photos can be done quickly a large number of output without manual paper cutter.
========================
[Features]
---------------------
1, [Green]
Dry type Kuoyin only physical photo paper to absorb the ink reaction is completely different from the traditional photo printing technology. Not only the speed is very fast, the more important it is to fully comply with the concept of low-carbon environment: green pollution-free, without drying, without complex procedures, do not need to ask a professional mechanic, absolutely no harm to the operator and customer.
---------------------
2 [flexible mobile]
Generally smaller size of dry type Kuoyin equipment, covers an area of ??not more than one square meter Zhuo. The work can be carried to the need to shoot the scene, fast output and the convenience of our customers.
---------------------
3, less power consumption]
Small body, the program design itself is not complicated printing equipment, power consumption in general in about one hour 750W ~ 1200W.
---------------------
, [Format long]
In the case of a fixed width, enlargements machine length up to 36 inches.
---------------------
5 the enlargements speed]
3R hour a piece about 750-1200.
---------------------
6 [photo effect]
Dye-based inks for its bright colors and good reduction to make the picture more real, rich layers, showing a three-dimensional texture.
But note: If you are a professional photo output, we must be cautious in the choice of printing paper.
Different grades of printing paper, its effect is not the same as the print. Printing paper is poor, the screen will feel rough, but the lack of luster.
========================
[Features]
The ink-jet dry type with respect to the use of dye-sublimation, inkjet
Lower cost high-volume commercial production.
Digital photos or traditional film output effect within a reasonable output format close to or even more than traditional chemical process production photos.
Jet dry type characteristics is the input digital image files, output media photos of traditional silver halide photographic paper.
Then we can the original image file on the computer for a variety of arbitrary effect, in order to achieve the intended use.
A variety of post-processing, such as wedding photography, making a variety of special-purpose photo of the variety of greeting cards, postcards, framed photos, calendar photos derivative products.
In this case, the ink-jet dry type is more like a printer, as long as you have the nerve, no matter what pictures you can produce.
4 can lower the cost of production of larger slides, by scanning, and then to the chemical output than ordinary inversion straight discharge cheap.
