I _RIt is intensity of reflected light.

The present invention approves translucent/clear area 6 can not be light transmission body completely, promptly they can absorb and/or reflection and/or scattering part light.If the ROD in transparent or semitransparent district is better less than 0.5 less than 1 then preferable.The difference of the optical density in translucent areas 6 and photoresistance district 5 should be enough greatly to produce tangible sight equation.TOD difference between the district 5 and 6 preferably should be greater than 0.3.According to the present invention, the district is 6 preferably transparent, is optically transparently also will get well.

The pattern in photoresistance district 5 and/or transparent/translucent district 6 can be the pattern of any cell array, parallel lines, point, circle, square etc., they can be arranged in array, the form of pattern, irregular array or the mode at random of rule.Virtually any size can be got in clear area 6, and this depends on the display unit of employing, and its diameter is usually in 0.1mm to 8mm scope, preferably between 0.2mm to 3mm.Clear area 6 can be selected as required with the ratio in photoresistance district 5, but usually between 0.3 to 3, generally is taken as 1 approximately, promptly 50% of surface region is covered by clear area 6.According to the present invention, sihouette pattern 2 can be provided by any spatial light modulator or optical filter in a plurality of discrete photoresistances district 5 and/or a plurality of discrete transparent or semitransparent districts 6 of comprising.Spatial light modulator or optical filter 2 can be the patterns that is similar to the sihouette pattern described in the EP-A-0170472 or is produced by the back of the body irradiation of liquid crystal (LCD) display unit or other any appropriate display.

Place display unit 3 and/or display unit 4 can with spatial light modulator or optical filter 2 co-extension spatially.Display unit 3 or 4 can show by four layer 7-10,7 '-10 ' full-color image that schematically illustrates, image is divided into transparent or semitransparent district 6 and color pattern district 7-10,7 '-10 ', so that the transparent or semitransparent district 6 of spatial light modulator or optical filter 2 and the translucent or clear area 6 of display unit 3,4 align (registration).Display unit 3,4 can be a print image.For example, according to EP-A-0170472 or similar, perhaps can be the LCD or the LED display unit that can show monochrome or full-color image.Have at least one can be black or dark-coloured pattern in the display unit 3 or 4.

Display unit 1 can be a self supporting type or superimposed on the substrate such as category of glass or polymeric material slide.Glass or polymer sheet can be superimposed on display unit 3, the display unit 4 or can be inserted between layer 7-10,7 '-10 ' or display unit 3 and sihouette pattern 2 between or between sihouette pattern 2 and the display unit 4.Substrate can be the window or the flexible polymer sheet of car, bus or building.When display unit 3 or 4 for black or furvous and when being positioned near the slide 1, by being the display unit 3,4 that slide is dyeed and can partly or entirely provide dark described in 0133761 according to european patent number.

Fig. 2 illustrates the block diagram of first embodiment of the invention.The suitable pattern image that shows usefulness produces in image generation apparatus 12.Image can utilize computer 13 and for producing special-purpose software that graphic image develops (as Adobe Photoshop ^TM, Adobe Illustrator ^TM, Corel-Draw ^TM, Aldus ^, Pagemaker ^TM, Quark Xpress ^TMDeng) produce.Image generation apparatus 12 can be a scanner, adopt it can the whole and partial images information pointwise of image, picture or photo be converted to and can be used as numerical data and be stored in the signal of telecommunication in the computer 13.

In case graphic image has been stored in the computer 13 as digital data matrix (it comprises that abundant data are to determine the brightness and the color of each pixel in the information), can prepare data like this, can show it with a plurality of clear areas in the graphic image 6.

According to the present invention, can carry out with several distinct methods:

Method 1: the dichroic layer (be generally CMYK, bluish-green bag, peony, yellow and black are CMY if perhaps do not adopt black layer) that can change data is to comprise the achromatic data of representing clear area 6 in each layer.This change to data can be carried out in computer 13, but the invention is not restricted to this.In computer 13 by the pattern of clear area 6 can be provided on graphic image as " colourless " area overlapping clear area 6.Achromatic data can be used as grating or pixel data and stores.Usually, do not need to change United States Patent (USP) 5,253, disclosed in 084,5,258,832,5,264,926 or 4,758,886 in order to produce the halftoning algorithm of full-colour image.Yet, if the clear area diameter that adopts less (＜0.5mm), can select clear area 6 and size at interval thereof, making them is not the multiple of halftone cell size, to avoid the harmonizing color drift.Adopt small size clear area 6, method 2 is preferable.Translucent/clear area 6 can be rule, the irregular or random array of point, line, square, circle, polygon etc. or represent pattern or the independent array of image.Can change the size and the distribution of clear area 6 by image.

As shown in Figure 3, clear area 6 can be the attracting again pattern 5,6,11 of a kind of complexity, and it comprises image area 22 and transparent pattern part 23, the former can be a photoresistance, the latter by by photoresistance district 5 area of images around transparent/translucent district 6 form.Clear area 6 can have different diameters and shape, so that correctly represent the details of pattern.Should be understood that at the reverse side of pattern 22,23, can show full-color image 3 or 4.The expression of pteridophyte leaf filament pattern needs strictly to print the small size clear area 6 of the repetition that is separated by basic opacity 5 so that produce vividly again pattern clearly in by a plurality of clear areas 6 of multilayer printable layer registration.

Method 2: represent the data of clear area to be stored in a individual course-" T " layer in the computer 13.The demonstration output file of computer 13 comprises color layer, CMYK or CMY layer that color separation once prints, adds the T layer.As will be described below, can use information in the T layer with different modes.For example, handle the place of (RIP) carrying out rastered picture, immediately the data of T layer are incorporated in each layer of CMYK among the final bit map figure during RIP or RIP after.These data are incorporated into the advantage that has the little repetitive structure distortion of minimizing among the grating bit map figure and improve final image registration.Because each color separation bit map figure has identical position, clear area.On the other hand, the T layer can be crossed RIP and be shown control circuit and be used for controlling display unit 3,4 in the mode that produces clear area 6.For example, be the place of printer in display unit 3,4, during printing, can produce clear area 6 by driving or remove the driving printer port of printer according to the T layer data.

Method 3: method 3 is the improvement to method 2, has adopted independent transparent data layer T.Difference is the form of data.According to method 3, storing the transparency data with the identical mode of storage dot matrix, different is point is not the colour point in the final display of representative but represents clear area 6.Can duplicate all word processings and graphics software technology conversely, data are not the colored points of representing on the white background, but represent the clear area in the photoresistance background.For example, data can be used as transparent font storage.Therefore the letter that resembles " T " is stored in the computer as the character that comprises predetermined clear area 6 arrays that Fig. 4 A illustrates.In " T " pattern, promptly when producing the data of hyaline layer T, crucial stroke " I " has been stored clear area 6 arrays shown in Fig. 4 A.Equally, can adopt the transparency graphic package to produce pattern in the clear area.Therefore, can produce straight line or other shape.Fig. 4 B shows graphical element: the rectangle of transparent dot matrix and straight line.

Method 4 is the improvement to method 1, wherein also comprises sihouette layer 2 except CMYK or CMY layer.The sihouette layer 2 that comprises can be used as light color point color, especially white usually.It contain with CMY or each layer of K in the transparency data transparency data of registration mutually.

Method 5 is the improvement to method 2, wherein also comprises sihouette layer 2 except CMYK or CMY layer.The sihouette layer 2 that comprises can be used as light color point color usually.In preparing the sihouette layer 2 that shows, can adopt at CMYK or the described same procedure of CMY layer (for example RIP).

Method 6 is the improvement to method 3, wherein also comprises sihouette layer 2 except CMYK or CMY layer.The sihouette layer 2 that comprises can be used as light color point color usually.In preparing the sihouette layer 2 that shows, can adopt at CMYK or the described same procedure of CMY layer (for example RIP).

Method 7 is the improvement to method 4, wherein also comprises the image of display unit 4 except first image of display unit 3 and sihouette layer 2.Second image that comprises can be used as additional C MYK or CMY layer usually.They comprise with all in other layer the transparency data transparency data of registration mutually.

Method 8 is the improvement to method 4, wherein also comprises the image of display unit 4 except first image of display unit 3 and sihouette layer 2.In preparing second image 4 that shows, can adopt CMYK or the described same procedure of CMY layer (for example RIP) at first image 3.

Method 9 is the improvement to method 6, wherein also comprises the image of display unit 4 except first image of display unit 3 and sihouette layer 2.In preparing second image 4 that shows, can adopt CMYK or the described same procedure of CMY layer (for example RIP) at first image 3.

For method 1-9, image is output to display unit 14, and according to the present invention, it can be the direct display unit that is similar to LCD or light-emitting diode display, indirect printing equipment 16-19 or direct printing equipment 20-21.

The method of video data depends on data storing method,

Method 1,2 and 7.Because these methods are stored in transparent data in each layer of CMYK or cmy data, so, as long as these CMYK or cmy data can show the number of plies of ad hoc approach,, can handle CMYK or cmy data as in conventional display device.

Method 2,3,5,8 and 9 comprises the T hyaline layer that one deck is independent, and display unit of the present invention can be handled it.On more existing graphics softwares, can stipulate the brocken spectrum color or stipulate the some color of any required color, improve display unit and make it be shown as this color transparent.According to this application, can processing method 2,3,5,6,7 and the device of 9 data be called as hyaline layer display unit or TLD device.

When the display unit 3 of seeing Fig. 1 from anterior view or 4 and illumination level on this side when higher, clear area 6 is rendered as dead color, is generally black.If image to be shown is provided by clear area 6 simply, and the color of image is not made improvements, so, image seems equably than darker originally.When display unit 3,4 placed near the same image that do not have clear area 6, this situation was obvious especially.When windows of vehicles and figure are extended on the vehicle body this situation can appear when display unit 3,4 covers.Fig. 5 (prior art) illustrates the photocopy of the photo of a row train, is added with big white letter on the train side.The white letter passes window, and window is covered by tradition perforation film graph window.On the train vehicle body, can be clear that apparent different with adjacent region 52 of window region 54 gray scales.Also color change can occur in the described arrangement of Fig. 3, wherein Tu Xiang full color part 22 can be adjacent with the part 23 with clear area 6.The following example of the present invention provides the scheme that addresses this problem.

The technology of known undercolour removal in printing and photography (for example referring to " reproduction of color in photograph, printing and the TV ", FountainPress, second edition, 1988).Not dark space, but utilize undercolour removal, the black content of color for example is provided respectively by independent black toner or printing ink with the combination printing or the demonstration image of three kinds of traditional colours (blue-green, peony and yellow).According to present embodiment of the present invention, utilize this technology in a kind of mode of novelty.When preparing data presented, the computer graphics program of computer 13 is carried out undercolour removal in common mode among Fig. 2, yet, in undercolour removal, considered the apparent dark color of clear area 6.For example, if 50% area of image is provided by clear area 6, so, only the black content with X% will show that black content is the colour of 50+X%.Because all the other black of 50% are to be provided by the clear area 6 that shows black, shown image is a RGB.Be lower than 50% colour for black, do not show black.This causes color darker than original color, and still, total effect still improves.In order to prevent and not having difference between the image light color district of clear area 6 that increase black for the light color district (for example outside in Fig. 3 window region or zone 22) of the image that does not have clear area 6, being actually background color increases.The example of being given more than adopting if color only contains 10% black content, so, is removed this composition as far as possible fully from this color in the zone of clear area 6.In the image area that does not have clear area 6, same color has increased by 40% black so that the coupling of color in the whole image.

For some embodiments of the present invention, from the opposite side of sihouette layer 2, promptly see that from display unit 3 these sides display unit 4 is that part is visible, this is an acceptable.This may be because (for example by several Method of printings) can not produce the sihouette layer 2 with the display unit of making 4 complete optoisolated this opacity.When display unit had dark color, the result of photoresistance rather than opaque sihouette layer 2 deepened all colours of display unit 3.According to the present invention, correct by background color, if this is impossible, then, also can compensate any deepening of display unit 3 shown images by increasing the black content of any part that is positioned at the outside, 6 zone, clear area in the image 3.

The another kind of method of compensation clear area 6 deepening effects is to make these area part metallization.This has the reduction transmission and the effect that gains from visual 3 reflected white-light is provided.In order to realize metallization, utilize the known technology of two-way speculum to carry out partially metallised to the whole surface of substrate.

Display unit 15 directly or simultaneously according to the present invention be such display unit, and it can directly show image at least from the electricity output of computer 13 and combine with sihouette pattern 2 makes clear area and the visual clear area registration mutually of sihouette pattern 2.Fig. 6 illustrates this direct display unit 15 according to second embodiment of the invention in the mode of schematic diagram.Carry out addressing by 28 pairs of traditional LCD displays 24 of selected cell, use conventional methods, as selected cell 28 being connected to computer 13 by cable and connector 29.LCD array 24 can form the part of window.Back of the body irradiation or reflector 25 place after the LCD array 24, and it has a light source 26 that is connected to the suitable power source (not shown) through cable and connector 27.

Back of the body irradiation 25 produces illumination with the form of the bar shaped that distinguished by transparent material, square, circle or analogous shape, thereby produces sihouette pattern 2 as described in Figure 1.Fig. 7 illustrates an example of this back of the body irradiation 25 with schematic diagram.Back of the body irradiation 25 is made up of the optical fiber 30 of the distribute light that a series of generations are separated by clear area 31, and clear area 31 can be the transparent material such as the optical clear acrylic resin.Optical fiber 30 carried out improving they are distributed to the light from light source 26, with perpendicular to back of the body irradiation 25 to the direction on LCD display 24 planes along its length with the distribution mode radiant light.This can be undertaken by introducing scrambling 32 (being called the optical element such as slit) on away from each optical fiber 30 surface of LCD display 24.In the article of exercise question, this optical fiber 30 that comprises a series of distribution light cones of generation of fiber optic component 32 has been described for " to the control (Mary Poppendieck and David Brown; 26-29 day in February, 1996 is published in international conference of AdvancingMobility Land Sea Air and Space engineering association and exhibition) of the light output of the plastic optical fiber that has optical element ".

In the time of on optical element 32 is arranged in away from each optical fiber 30 side of LCD display 24, each light cone is reflected on the LCD display 24, thereby to parts, as bar shaped or 24 illuminations of rectangle LCD display.As illustrated in above-mentioned article, can be spaced optical element 32 along optical fiber 30, make that according to the distance of leaving light source 26 interval of optical element 32 is nearer or be deep in the optical fiber darker.Adopt this method, can realize evenly extracting light along the length of optical fiber 30.

At United States Patent (USP) 5,226,105,4,907,132,4,885,663,4,845,596,4,519,017,4,234,907,5,432,876,5,187,765 and 5, provided in 005,931 how from optical fiber, to produce further describing of back of the body irradiation, here that all these patents are incorporated by reference.

LCD display 24 is driven by computer 13 and selected cell 28 through cable and connector 29, thereby only these liquid crystal cells that thrown light on by optical fiber 30 in the LCD display 24 is carried out addressing with the data of image 3 or 4 among the application Fig. 1 of 2 or 3 preparations according to the method described above.When the clear area hour, if the introducing of clear area is delayed to and shows that eve is preferable in the data.For example, in computer, at first prepare the output data file of image on the display unit.Then, introduce the clear area.Have been found that particularly that in the clear area 6 is less and when being in the regular array, introduce the clear area in stage early and adopting other algorithm (as filtering) can cause these clear areas to be distorted when image is handled.

Allow to carry out above-mentioned undercolour removal for the partially transparent district 6 in to be shown visual 3,4.In LCD display 24 zone opposite with back of the body irradiation 25 clear areas 31, computer 13 output related datas make that LCD display 24 is transparent in these zones.Therefore, be presented at the image the 3, the 4th on the LCD display 24, constitute by the zone of the image 3 that is thrown light on by optical fiber 30 that is separated by clear area 31 or 4.When the front of LCD display 24 is watched, can see by clear area 6 separate whole visual 3 or 4, be shown as dead color when LCD display 24 is positive goes up general ambient light when general ambient light on LCD display 24 back sides is lower than.On the other hand, when when the back side of LCD display 24 is watched, the clear area 31 that the opacity that display unit 25 has to be provided by optical fiber 30 back sides separates.

According to the improvement example of second embodiment, back of the body irradiation 25 can be provided by the series of LED unit 33 that is separated by clear area 34, as schematically shown in Figure 8.LED element 33 can form straight line square or circular or analogous shape and so arrangement, makes and invests LCD display 24 from the light of LED element 33 reflections.Therefore, these parts that contain pictorial data in 33 pairs of LCD displays 24 of LED element are thrown light on, and pictorial data is fed to LCD display 24 through connector and cable 29 and selected cell 28 from computer 13.Provide clear area the LCD display 24 from the data of computer 13 output, this clear area and back of the body irradiation 25 clear areas 34 shown in Fig. 8 are registration mutually.

In addition, can be indirect printing equipment 16-19 according to the display unit in the third embodiment of the invention 14.

Indirect printing equipment according to the present invention be with each minute color picture therefrom between the painted successively Method of printing of transferring on the printing substrate on the image carrier.Usually, this needs a component color, and promptly main monochromatic intermediate image substrate 17 is used to produce final print image 19 in printing equipment 18.Intermediate image substrate 17 produces in the computer output data from middle image device 16.This indirect Method of printing can be for example lithographic printing or silk screen printing.

With reference to lithographic printing, imaging substrate 17 can be to be suitable for lithographic a series of imaging polyester printing editions on printer 18.Lithographic printing substrate 17 can directly be produced by computerized information in suitable image device 16.Can adopt one group of lithographic printing substrate 17 whole and part of image 4, sihouette pattern 2 and image 3 among printing note invention Fig. 1 successively.For example, as shown in Figure 9, image 4 can be on the slide 41 with the pattern of the piece 42 of photoresistance white sihouette pattern 43 registrations, be printed on 4 color picture 44-47 of whole registrations on it, stay clear area 48.The preparation of data can be undertaken by any method in the said method 7 to 9.Therefore, may need 6 substrates 17 altogether: black, white, blue-green, peony, yellow and black.In order to obtain the opacity of enough color depths or printable layer 42-47, can repeatedly adopt each substrate 17 for every kind of color.In the place of adopting dark-toned slide 41, can omit first black layer, only use five kinds of color layers: white, blue-green, peony, yellow and optional black.Then can be according to the method described above any preparation data in 4 to 6.In order to obtain good registration between the different lithographic printing substrates 17, can produce these substrates here by the method described in the European patent continuation application EP 95106746.1 that submits to May 4 nineteen ninety-five incorporated by reference.

Behind the middle imaging substrate 17 of pictorial data preparation, in printer, on transparent film, print 19 at last in a conventional manner.The printing film that all embodiment of the present invention are adopted is integrated, and contacts because selected substrate has integration characteristic and integrates first type surface of adhesive layer and substrate.

As shown in figure 10, can be according to another kind of order print colors layer 42-47.The order of color layers 42 to 47 can be conversely, and the color of Da Yining is a black layer 42 at last.In the time of on being applied to the window substrate, transparency carrier 41 can form the overlapping layer of skin or substrate 40 now.Can at random adhesive phase 50 be applied to printing one side of substrate 40, so that substrate 40 is fixed on window or the similar object.Adhesive phase 50 can be below with reference to the described any adhesive of overlapping layer.If the transparency carrier 41 of Fig. 9 and 10 is that the optically transparent vinyl pieces according to eleventh embodiment of the invention is preferable.If adhesive phase 50 is optical clears also is preferable, preferably acrylic pressure-sensitive adhesive.

Although it is preferable adopting contact adhesive,, on substrate 41, can adopt any adhesive that is particularly suitable for selected particular substrate and end user's application.This adhesive is that the state of the art personnel are known, can comprise aggressive tack adhesive, contact adhesive, can recovery and/or positioning adhesive, hotmelt etc.Contact adhesive is common described in contact adhesive handbook (second edition) (Von Nostrand Reinhold 1989), and is here that its content is incorporated by reference.

In addition, as shown in figure 10, by at the sihouette pattern, promptly producing the clear area 48 that is slightly less than dichroic layer 44 to 47 in the white layer 43 can compensate any registration error between the printable layer 42-47.Equally, can make clear area 48 in the black layer 42 be slightly less than clear area 48 in the white layer 43.In this way, the misalignment of dichroic layer is not invaded in the clear area 48, same, the misalignment in the white layer 43 does not invade in the clear area 48 in the black layer 42 yet.

Middle imaging substrate 17 also can be a cocainine net of silk screen printing equipment 18 usefulness.Then, as known to the professional in the silk screen printing technique, the output of computer 13 is fed to automatic silk screen generation device 16.Printing color produces final image 19 to utilize silk screen 17 and traditional silk screen printing technique to pass through successively.

Indirectly the major defect of Method of printing is in turn middle imaging substrate 17 to be placed in the printing equipment 18, be difficult to keep image 3 among Fig. 1 and 4 and sihouette pattern 2 each layers between strict registration, need carry out time-consuming proof and adjusting.Utilize the full color laser printer can obtain some improvement.In this case, provide middle imaging substrate 17 by the mode that palette is attracted to bulging static electrification district by the imaging semiconductor drum that is used on substrate 19, printing.Six or more a plurality of bulging expensive dedicated printer that needs are provided, perhaps on the other hand, utilize six meetings of same drum to cause being difficult to strict registration.The AGFA Chromapress that Belgium AGFA-Gevaert NV company provides ^TMThe static dump system can be according to indirect printer of the present invention.This system comprises 8 printer drums, is treating that 4 drums are arranged a row on each side of printing substrate.Print wheel is to improve visual computer plotting system control by being suitable for producing the present invention.This system aims on paper to be printed and design, but it can be improved at transparent film, especially makes somebody a mere figurehead on this optical clear mylar known to transparent and prints.

According to the 4th to the 16 embodiment of the inventive method, if display unit 14 is that direct printing equipment 20 is preferable.According to the present invention, directly printing equipment can directly be deposited on the colouring agent of full-colour image on the single printing substrate.Printing substrate can be finally to print goods or Intermediate substrate.Therefore, method of direct printing is the method for imaging substrate 17 in the middle of not utilizing a group, must use these substrates successively in order to print in printer 18 on substrate 19.Can be the full-color image on the single Intermediate substrate of substrate 21 or transferred image (as moving picture) usefulness with the signal transition of computer 13 according to direct printing equipment 20 of the present invention, so that produce for example Fig. 9 or 10 substrates of being illustrated 40.

This method of direct printing can comprise, such as the ink ejecting method of bubble ink-jet and spark ink-jet, heat and piezoelectricity pulse ink-jet; Heat-transferring method such as distillation or mass-heat transfer printing; Or static or photoelectricity photograph Method of printing, but be not limited thereto.According to the present invention, method of direct printing can also be the static printing method, the ScotchPrint that provides as 3M company ^TMElectronic Graphics System, wherein electrostatic image at first produces on the static paper of special use, and once-through operation is transferred in the transparency carrier 21 then.Above-mentioned ScotchPrint ^TMMethod and such as silk screen print or lithographic printing etc. indirectly the difference between the Method of printing be: the transfer printing of image is to adopt that single substrate carries out and is panchromatic, and Method of printing will utilize a component color imaging substrate 17 so that produce full-colour image indirectly.The registration of static dump is better than the registration of indirect Method of printing greatly, and is irrelevant with the transfer process that adopts.

An example of the Method of printing that adopts among the present invention comprises: or with sheet form or with the dispensing form material is sent into the printer from cylinder; print required chromatic image and sihouette pattern 42-47 according to the present invention; searching image from printer; randomly image and film 50 are overlaped and accept coating and image avoids being subjected to water, delineation and other may cause the influence of source of damage to image with protection; remove release liner then, print image is fixed on the transparency carrier of watching.

If it is preferable that method of direct printing has good local registration.The example that good local registration is printed is to produce with traditional high-quality ink-jet printer, and it can print quite panchromatic regional area.Therefore, accepting to obtain very high-quality registration partly on the media.Owing to around each little clear area of image, need very high resolution ratio,, on long distance, allow whole image that some distortion are arranged so good local registration is favourable.On the other hand, the distance between every kind of color platform of electrostatic printer is several centimetres, carries out full color and prints so can not resemble the ink-jet printer part, even adopt the trafficability characteristic machine one time.

Many factors can influence the local registration of printing.Between two kinds of colors of ink-jet printer on substrate mobile 2-3mm distance, and the electrostatic printer of a trafficability characteristic moves 100 to 150mm on substrate, such as Summagraphics SummaChrome ^TMThe thermal transfer printer of imaging system is printed on whole zone before changing color.Test has shown that the amount of movement between the change color is not the reliable indication of local registration degree.

Printer is usually used " counting of per inch ", and promptly DPI characterizes.Test has shown that DPI is a well indication, still, as what can see from following table 1, but is not an indication that does not make mistakes for the selection according to printer of the present invention.

The warpage of substrate 21 or Intermediate substrate 17 or distortion or thermal expansion also can influence or reduce the theoretical level of local registration.

The degree of having determined local registration is actually determined by printing fc-specific test FC image, and the fc-specific test FC image comprises the specific full-colour image of the regular array of the transparent circle that has different-diameter in the image.When the diameter of clear area is reduced to certain value when following, the error in the printing registration makes the diameter of each clear area significantly reduce.

The fc-specific test FC image preferably is made of all layers to be printed, and each layer is with 100% color printing, and each layer comprises the pattern of transparent circle, and its diameter reduces with each layer registration with other.For example, in turn print the color layer of black, white, dark red, yellow, bluish-green and black with 100% tone intensity, each layer comprises transparent circle array.When colour was 100%, any misalignment all was easy to find out, because shades of colour invades in the clear area and reduces its diameter.

According to the present invention, " the local registration index " of related printing process/printing machine (LRI) is defined as clear area diameter (mm of unit) when most clear area diameter has been reduced to its expection diameter 50% in the printed image in any direction.Provided the representative value of some business printers in the table 1.Actual LRI value depends on the degree of accuracy that printer or calibration are set.When printing four kinds or more colors, 1.0mm is favourable if the local registration index (LRI) of printer of the present invention is better than (promptly less than), and is then better less than 0.6mm, then better less than 0.3mm.

^*Print quality is very good, promptly is difficult to the definite limit that external effect caused that may be introduced by mapping software.

Usually, sihouette pattern 2 comprises photoresistance light color or white layer or argent or the gold layer towards Fig. 1 display unit 3 and/or display unit 4.According to the present invention, this photoresistance bleached bed 2 can utilize light color, argent or white ink or palette to print according to the Method of printing that is adopted.The point color of white is preferable." photoresistance " is meant that the transmission optics density (TOD) of illuvium is at least 1.0, is at least 2.0 better, and 2.5 are better, 3.0 or bigger then best.Utilize 13 pairs of required softwares of computer graphics of computer to improve according to the present invention, thereby adopt white tone colour table or printing ink, and the clear area is distinguished and " printing " as " no printing ink " as a color printing white portion.

In order to prepare the data of graphic designs, can at first produce the image 3,4 of the data that comprise photoresist layer 43 and be stored in the computer 13.Can carry out undercolour removal of the present invention to aforesaid pictorial data.Image is normally as every kind of main print color (as black, bluish-green, dark red or yellow or some color) dichroic layer of data or plane storage.With traditional equipment, below adopting data preparation method 7 and producing: represent layers 42 100% black or dark datum plane as first image 4 in the mapping software.This can be used as a color system and produces.Then, produce 100% white, silver or the light datum plane of representing bleached bed 42.At last, produce the data of layer 44-47 as panchromatic graphic image 3.It is preferable that black and white layer 42,43 is defined as a color.This can cause producing 6 data groups or plane usually: one is that 42, one of darky systems are that 43, four of white layer are the dark red, yellow, bluish-green and black layer 44-47 of panchromatic printing employing.Yet, the invention is not restricted to this.Handled the place of black can producing high-quality, promptly produced the place of black, can omit last black layer 47 from bluish-green, dark red and yellow secondary colour.And, can omit first black or dark layer 42 in the place of adopting the toning substrate.

One or more in can application layer 42-47 as multilayer.For example, can store white layer 43 as a series of datum planes of representing white layer 43, so that in final the printing, obtain enough opacity.

In computer 13, can produce the array of clear area 48, utilize overlapping or other technology, pictorial data be made amendment by clear area 48 is incorporated in each layer data of representing printable layer 42-47.Usually, for printing equipment 16-21, constitute " EPS " individual files and these files are sent to relevant middle image device 16 or printer 20 by the modification image that comprises clear area 48.In addition, it is preferable clear area 48 being incorporated into the final steps for the treatment of to be deferred in the print data before producing middle imaging substrate 17 or printing formation print image 21.This preferably utilizes data preparation method 5,6,8 or 9 to realize, wherein from the independent T layer of computer 13 outputs.When the output data grating image processing with computer 13 becomes the grating bit map of different printable layer 42-47, the T layer data is incorporated in CMYK layer data and the sihouette layer data.The benefit of doing like this is with algorithm data to be carried out computing, for example ready-to-print file, change ratio, to become dos format etc. from the MacIntosh form be to carry out before the small size repetitive structure that resembles clear area 48 is incorporated into the pictorial data.Because truncation error, the small size repetitive structure when utilizing algorithm to carry out computing in the numerical data can distort.The rhythmicity that this distortion can make image size and shape occur changes or the lost part image.

In order to protect print result, can adopt transparent outer lamination 49, it is preferably optically transparent.If the optical transparent film that outer lamination 49 is eleventh embodiment of the invention is preferable.

In this application, outer lamination 49 is meant to be adhered to existing anyly have coating or does not have the lip-deep any transparent material of coating material sheet." outer superimposed " is meant and realizes this bonding any process, especially do not have the trapping meeting to damage finished commodities or apparent bubble, pleat trace or other defective of image.

The non-limiting example of release liner comprises the Kraft paper that is coated with silicone, is coated with the polymeric material that silicone is coated with polyethylene paper, scribbles or is not coated with silicone, as polyethylene or polypropylene and the polymeric material that scribbles the polymer antitack agent, as silicone urea, urethane and chain alkyl acrylic acid, as United States Patent (USP) 3,957,724,4,567,073,4,313,988,3,997,702,4,614,667,5,202,190 and 5, defined in 290,615, here that its content is incorporated by reference.

According to the present invention, can after RIP, introduce the clear area in printing.Printer 20 or middle image device 16 can be " TLD " devices of constructing for the clear area of introducing figure.For example, when printer was ink-jet printer, printer can be constructed like this, did not carry out the printing of whole printing substrate width under well-regulated interval.This produces a series of parallel clear areas.On the other hand, can repeat repeatedly to make the printhead inertia, to produce the distribution of square or rectangular.If printer 20 is electrostatic printers, can make a part of inertia of each printhead or lose, this produces a series of vertical clear areas.In turn make a part of inertia of printhead, to produce square or rectangular.

Utilize T layer data control printer 20 can produce TLD printer of the present invention.After rastered picture is handled, utilize the T layer data can adopt another kind of algorithm to carry out the computing of grating bit map, it changes the grating bit map, makes to produce the clear area when printing.This improvement can be carried out by hard-wired circuitry in the printer 20 or by the software that moves on the local processor in printer 20.On the other hand, can adopt the T layer data directly to control printhead.For example,, can suppress to be input to the print signal of printhead, on desired location, produce the clear area according to the T layer data for ink-jet printer.

A fourth embodiment in accordance with the invention adopts ink-jet or jet bubble Method of printing to print sihouette pattern 2 and image 3 or 4.Inkjet printing comprises the whole bag of tricks that thermal inkjet-printing and piezoelectric ink jet are printed.The common ground of all these methods is that the printing ink of dispersion amount sprays to receptive layers from superfine nozzle.Recently, the printer of wide format has been arranged on the market, therefore, the printing that resembles the big goods of heavy construction drawing, blueprint and colored poster and symbol comes true.The transparent polyester mask 8501/8501H that the non-permanent suitable receptive layers that uses can provide as 3M company.Optical clear flexible ethylene substrate substrate according to eleventh embodiment of the invention is good especially.Utilize various business-like printing techniques can form ink jet image accurately.Suitable big form printer is HP Design Jet 750C or the 755CM printer that Hewlett-Packard provides, and comprises the transparent membrane and the printing ink of approval, yet, also can provide other trade mark.Infinite example comprises the thermal ink jet printers of the DeskJet trade mark, the PaintJet trade mark Deskwriter trade mark, the DesignJet trade mark and other printer that Hewlett-Packard provides and such as piezo-electric type ink-jet printer, spraying printer and the continous inkjet printers of Seiko-Epson.Realize the present invention, except four kinds of colors commonly used: bluish-green, dark red, Huang and the black, also should increase other look box to printhead.For black layer in printed drawings 9 or 10 42 and white layer 43, need to increase in addition a white platform and black platform at least.For the opacity that obtains, perhaps to increase two or more whites or black look box to printhead.

From the test result shown in the table 1 as can be seen, inkjet printing provides local registration accuracy high printing.The ink-jet ink of band pigment is provided by Commercial Graphics branch of 3M company.Usually, the jetted ink of the band pigment of 3M company is a band aqueous pigment printing ink, and it comprises the suspension of the granules of pigments of selling on the market and the dispersant of following molecular formula:

Wherein, R removes alkyl, the aryl or aralkyl group that primary amine group obtains from alkylamine, arylamine or aralkylamine;

M is 1 to 6;

R ³And R ⁴Be hydrogen or low alkyl group;

R ⁵Be the residue (residue) of nitrogen reactive compounds (nitrogen reactive compound), described nitrogen reactive compounds is selected from acylating agent, carbamyl halogen, sulfonamides halogen, alkylating reagent, alkylation (epoxides) reagent, different (sulphur) cyanate, sulfonating agent and azlactone reagent;

R wherein ²⁰And R ²¹Respectively do for oneself alkyl, aryl or aralkyl group, or be selected from the cation of proton, lithium, sodium, potassium, ammonium or tetra-allkylammonium.

The pigment of jetted ink uses Standard Colors, i.e. cyan, magenta, yellow and black.

For black ink, carbon black can be used as black pigment.Selection is applicable to that carbon black of the present invention mainly is based on surface oxidation (being advisable with high " volatile matter ") and the blackness (being also referred to as pitch-dark degree (jetness)) of considering pigment.Acid or surface treated pigment provides suitable interaction position to be used for adsorbing strongly dispersant.The pigment that oxide on surface content is high is more hydrophilic, therefore easier dispersion.The higher pigment of blackness or pitch-dark degree can obtain high-quality printed image.

For Yellow ink, use nickel azophosphine pigment that several advantages is arranged.At first, these pigment make that printing ink out of doors can be highly durable under the environment.Secondly, these pigment contain nickel ion, and they can form fit key with novel dispersant.At last, these pigment are considered to provide the thermal conductivity of height.Consequently, if the phenomenon of particle deposition on heating element heater taken place in ink jet process really, deposited film can not reduce the thermal efficiency of printing ink significantly so, thereby makes it possible to form suitable bubble.For magenta ink, what mainly consider is light fastness aging, because be starved of the graphic image that obtains being fit to outdoor applications.Known quinoline a word used for translation ketone magenta pigment has good light fastness aging, is a kind of preferable magenta pigment therefore.

For green pigment, consider above-mentioned factor (being light fastness aging, durability etc.).Because copper phthalocyanine is had multiple satisfactory performance as green pigment, the printing ink that therefore comprises these pigment is a preferred embodiment.

Be preferably and can prepare painted jetted ink with the dispersant of following chemical formula:

Shown in the table concrete composed as follows of suitable dispersant:
