Description
Technical field
The utility model belongs to printing equipment technical field, and in particular to a kind of printing effect is preferably based on four-color process
ICC color separation printing equipments.
Background technology
Four-color process refers to be realized by mixing principle of losing lustre with Red Green Blue and black pigment (ink or dyestuff)
The lithographic process that full color replicates.Many printing enterprises strengthen high-grade color to improve company's colored printing product quality
Color printed matter occupation rate of market, the printing of product is all carried out using the good four-color press of effect.Described four-color press is special
Refer to the printing machine that black, middle blueness, brown and green four kinds of ink realize the lithographic process that map replicates.
Before " spectrum color seperation " forms four color Process Color printings, colored printing to open color by hand, is wrapped mostly
Include Ming Dynasty Chinese " wood-block printing " to cut blocks for printing and print to the color separation of up to a hundred editions with tens of versions, form picture quite true to nature, and originally
Paintings are several to look genuine.Ukjyoe, the brocade of Japan are painted, and are continued to use a kind of this painting style and printing mode, are added for Japanese common people's Life Art
Add many temperament and interest, as the landscape wood-block printing of Tokaido 50 three times, show many local conditions and customs, it is just deep to influence finally Europe
The continent impressionist painting style.When lithographic techniques pass to Japan, there is height artistic accomplishment artist to use " color is opened on stone plate " instead for some, with point
Retouch or open color right-falling stroke net skill and technique and show deep or light and texture, as long as the printing of more than ten, 20 colors just can form very exquisite lithographic printing effect, this
Kind purely with open color person experience person and judgement, using the set color ink printing of Western stone plate, vertical next extremely exquisite works are painted for brocade.
19th-century invention photography, " white photograph coloring skill " is more developed, so twenty beginning of the century used relief printing plate four
Color prints, and adds and subtracts color with carbon dust cartographic technique on glass plate continuously adjusting, such as greenery plus YC versions, subtracts M versions green color can be presented
Coloured silk, brick wall, which adds YM, subtracts C versions can be presented bronzing, such, and color is removed out with the general knowledge skill of colour-separation drafting person, rotten after netting western version
Erosion, forms four color relief printing plate original block colour postcards of intimate hand dyeing, this kind of technology is in day early stage according to TaiWan, China, Man Zhou
State and in Japan performance landscape, building image.
Other one kind be then based on photograph or watercolor, also with stone plate open color method with it is red, yellow, blue, green, grey,
It is black to wait color, it is full of version, site, point is retouched or lines, turns into chromatography completion, the picture that there is photograph or drawing to feel, is in Japan
Adoption brocade is painted and the skill and technique of Ukjyoe, and TaiWan, China artist Mr. Lan Yinding also once did this kind of color of opening for book cover and worked,
Autumn rain prints Lin Qiuyu president, and also oneself creation trade mark, exploitation open color printed works in one's early years.
These skill and technique still have use to generation nineteen fifty to the sixties, the TaiWan, China photograph four-color separation after the sixties
After method prevalence, color chromatography technology being opened by hand and is just progressively declined, everybody changes using egative film color separation, crosses net, four color deep-etch printings
As a formal technology, net color separation, electron scanning color separation were directly crossed later, organizes page system, to colour EPS today, was printed
Brush is using four color mesh sheet CMYK four-colour chromatographies into unbreakable pattern.
Due to being limited by colorant and production technology, C, M, Y, K primary color inks that four-color process uses print colour developing
The curve of spectrum has larger gap with the desired color curve of spectrum.Secondary colours CM, CY, MY color developing effect of ink trapping, particularly
Blueness and green are bigger with desired color gap.With existing Printing ink producing technique, ink performance is significantly increased, leaves
Space it is little.Therefore, four-color process colour gamut is more difficult very big extension.Four-color process is with print color density matching for a long time
Original copy density.Print color density is measured, is substantially the dosage for measuring printing-ink.As it was previously stated, print color by colour into
Divide and neutral ash component forms, under conditions of printing-ink reference amount is limited, if neutral ash component is excessive, not only cause to print
The larger distortion of map brushing image brightness characteristic, also relative color composition dosage can be reduced, cause color saturation to decline.Four-color process
The vision lightness near linear of color, show that the neutral ash component of print color is excessive.Four-color process emphasizes that lifting replicates face
The saturation degree of color, it is another major defect of four-color process technology using excessive sacrifice colour brightness as cost.With respect to nature scape
For thing color, due to disadvantages described above, four-color process copy colors are heavy, and contrast distortion is larger, and stereovision is untrue, third dimension
It is not strong.Therefore usually complain that printing quality is not high by client.
ICC curves, it is exactly briefly that ink producer coordinates the ink of oneself and different printer models by program
Make printing effect ideal.
It is well known that the colour gamut of the RGB in computer software is very wide, and computer uses computer language；
And C, M, Y, K that our printer uses either C, M, Y, K, LC, LM etc. are properly termed as printer language.Because for meter
The Color Language of calculation machine output has arrived printer and will have an Interpreter Officer to translate here, for example, combine it is black, in a computer
PHOTOSHOP softwares in we black can be set as C:50 Y:50 M:50 so one combination of computer export are black
When language, the driver of printer will send C:50 Y:50 M:50 instruction is to printer, and printer is according to this
Individual instruction carrys out jet ink and forms pattern.
Secondly, different materials has different reflections from different inks, compares casting figure printing paper, ink is in face coat
Chemical reaction be different, that is to say, that the number of amount of the ink when reaching these coating surfaces has different effects,
So just need to make a correction when computer language is transformed into printer language, such ICC curves just serve
Effect.Moreover identification and execution of the characteristic of different equipment also to these language generate difference, such as the EPSON first generation
Shower nozzle and forth generation shower nozzle etc., be different to these instructions and the recognition capability and executive capability of language, although ink
As ground, but different ICC curves are also formulated according to the situation of equipment.By similar to color management such as EYEONE
The cooperation of equipment and software, the simple and fast for becoming the production of ICC curves.EYEONE gets a mark by software on ground
Color lump, is then input in software, is compared with original color lump by accurate color lump by spectrophotometer, caused deviation
Value is exactly ICC curve files.Therefore, some producers and going of being ignorant of makes ICC curves, and do not understand the meaning of ICC curves yet,
Ink inferior is simply blent out after simply simply other inks are chemically examined, is not provided with perfect color service body
System, therefore played the role of the file similar to curve of part in the driver of printer, so desktop type is beaten
Print machine does not need the support of curve file, and using the non-curve for this equipment making, obtained effect is certainly bad.

μm.For ink film thickness, blue or green ink<It is pinkish red<It is yellow.According to bubble theory, according to ink film thickness, gradually increased order prints
Brush, i.e., by blue or green → pinkish red → yellow order, the double exposure situation of ink is best, is typically not in problem.If this
Order is changed, is changed into blue or green → yellow → pinkish red, then, yellow black double exposure is good on blue or green ink, but magenta ink double exposure is in yellow ink
It is upper just bad.It is pinkish red particularly in the state of wet pressing is wet because the ink film thickness that Huang ink is brushed on paper is thicker than magenta ink
The double exposure of ink is just more bad.Measured to make magenta ink double exposure good it is necessary to increase the ink of magenta ink, so, the net of magenta ink
Point will integrally increase, and cause magenta to deepen.If looking after site increase, and reduce pinkish red ink amount, then, magenta ink
Double exposure cannot obtain pure large red to Huang Moshang, and can only obtain orange, and secondary quality is incorrect, can influence certainly
The tone of image.In addition, the viscosity of ink is lower, then the speed of growth of bubble is bigger, therefore in ink colors double exposure in order,
The viscosity of ink should reduce successively.That is during assorted ink trapping, for the viscosity of ink, first the second colors of color ＞ ＞
The colors of 3rd color ＞ the 4th.According to the reasons why above-mentioned, when reasonably determining printing color-sequential in technique, in order that chromatography operation is smooth
