Embodiment
Embodiments of the present invention are described hereinafter with reference to the accompanying drawings.
Fig. 1 shows to be used for carrying out according to making of an embodiment of the invention and determines that the film multicolor patterns that forms usefulness of the multicolor patterns that is in harmonious proportion with ambient color forms the view of computer system configurations of method of the coating composition prescription of usefulness.System comprises: treatment facility 101, and it has operating gear; Image display 102 (hereinafter, being called " display equipment "), it is connected to treatment facility 101 and can shows full-color image; With metering facility 103, it is obtained about the colouring information of the object 104 that has been given multicolor patterns and by given interface and sends information to treatment facility 101.
At first, form the coating composition of usefulness with describing the film multicolor patterns that forms usefulness of multicolor patterns.The coating composition that multicolor patterns forms usefulness comprises the carrier components that forms transparent coating and small atypic colored particles.The average particle diameter of colored particles suitably can be determined in the scope from 0.1mm to 5mm, and the distribution of the particle dia of colored particles approaches lognormal distribution.When the coating multicolor patterns formed the coating composition of usefulness, the colored particles of same color contacted and is overlapping, formed the continuous unsetting zone (spot) of same color thus.Mix by colored particles, can produce and to form the coating composition that multiple multicolor patterns is filmed different colours.
Here, the color of colored particles is determined by the kind and the quantity of the coloured material that comprises in the colored particles.The ratio of the carrier components of all coloring particle is subject to storage, the workability when formation is filmed and the aspects such as performance of filming of coating composition.Form in the coating composition of usefulness at multicolor patterns, design of filming from multicolor patterns to be formed or the stable angle when forming multicolor patterns are used a kind of to three kinds of colored particles usually.In the present invention, describe, use three kinds of colored particles as the back.
Usually forming multicolor patterns by the coating composition of coating multicolor patterns formation usefulness on coloured base material films.The color of base material is to determine according to the design that multicolor patterns is filmed.Usually, even the color of base material is defined as making when the coating composition of multicolor patterns formation usefulness is hidden base material fully, can not experience inconsistent sensation yet.
Fig. 2 is the conceptive view that the target coating state is shown.The left side of Fig. 2 is a plan view, among the figure, (A) expression base material, (B) expression use have the formula ratio determined by the method for describing later, multicolor patterns forms the multicolor patterns that the coating composition of usefulness forms.Fig. 2 (C) is a viewgraph of cross-section, and among the figure, the superiors are that multicolor patterns is filmed, and the multicolor patterns following layer of filming is undercoat and base material.Every kind of colored particles of little pattern representative in the superiors, the space between the colored particles is tackiness agent (carrier).
Next, the coating composition determination of formula method that forms usefulness according to the multicolor patterns of an embodiment of the invention will be described in detail.Fig. 3 is a schema, has described and has used the system shown in Fig. 1 to determine that multicolor patterns forms the method for the coating composition prescription of usefulness.In the following description, the processing of being carried out by treatment facility 101 in response to operator's (planner or the like) operation is this processing, in processing, the internal arithmetic element (hereinafter, be called " CPU ") read to given data in the recording unit (hard disk drive or the like) internally, output to inner temporary storing device (hereinafter, being called " storer "), and storer is as workspace.CPU is recorded in result in the recording unit according to circumstances.
In the recording unit of treatment facility 101 inside, will specify the information (color name, code etc.) of colored particles and as associated with each other about the tristimulus values of the colouring information of colored particles and be stored in the database.Tristimulus values are a kind of psychophysical quantities, and it is expressed as numerical value with the sensation form that is fit to the people with color.Specifically, can be XYZ value, L
*a
*b
*Value, rgb value or the like.The several different methods that has the tristimulus values of the color be used to obtain colored particles.For example, spectral reflectivity that can obtain according to the color of the colored particles by measuring actual use or tristimulus values obtain the tristimulus values in the desired color space.Perhaps, can carry out known CCM (computer color coupling) by the prescription of coloured material (coloured pigment, dyestuff or the like) to be mixed in the colored particles of using according to reality and calculate tristimulus values.
In step S1,, determine the tristimulus values of ambient color to be in harmonious proportion then or be used to obtain the used data of tristimulus values by viewer's operational measure equipment 103.Send measured data to treatment facility 101 and be recorded in the recording unit.Color space is not limited, and can use three valuess that color can be shown as the numerical value with cross correlation.The several different methods that exists the adquisitiones of the tristimulus values of ambient color to use, and for example can be the method that describes below.
When multicolor patterns partly being coated to wall surface etc., the color of peripheral wall surface is served as the ambient color that multicolor patterns is filmed.Thereby, can directly measure the color of peripheral wall surface.The color measuring method is not limited to.Can use normally used colourimeter, spectrocolorimeter and spectrophotometer.When using luminance meter, treatment facility 101 is obtained spectral reflectance factor as the data by measuring, and can obtain above mentioned tristimulus values by calculating.When direct tristimulus values reader is used as colourimeter, can be with actual measured value as tristimulus values.Perhaps, during the colourimeter of the tristimulus values in using the color space that can not directly obtain in hope, the known function of treatment facility 101 uses can convert tristimulus values obtained in the color space to the tristimulus values in the desirable color space.
When can not directly measure the part that applied multicolor patterns around color the time, use luminance meter can obtain the tristimulus values of ambient color.Perhaps, use pick up camera to carry out and applied multicolor patterns imaging on every side partly, treatment facility 101 can obtain tristimulus values from the view data that obtains by imaging then.
Hereinafter, suppose that treatment facility 101 is from direct sRGB (standard RGB) value (Rt, Gt, Bt) of measuring or calculating ambient color of the data that transmitted.
In step S2, treatment facility 101 determines that the multicolor patterns that is in harmonious proportion with ambient color will form the color of base material thereon.The color of base material is according to the tristimulus values of the ambient color of determining in step S1 and definite.There is several different methods as described later in method for determine the color of base material from the tristimulus values of ambient color.Here, in order to simplify description, suppose to have the color of color (Rt, Gt, the Bt) selection of the tristimulus values identical as base material with the tristimulus values of ambient color.
Under situation about the color of base material being applied, when having determined tristimulus values, can determine to form the coating composition that base material is used by known method by the colored coating coating composition.For example, be provided with determined tristimulus values as target after, by carrying out the prescription that known CCM can determine coating composition.
In step S3, operator's operation processing equipment 101 is to specify the possible colored particles (at least three kinds) in the coating composition of multicolor patterns formation usefulness to be mixed from the database of recording unit.Here, supposed to specify the N kind colored particles that has from 1 to N Code Number.
In step S4, treatment facility 101 obtain with step S1 in the close tristimulus values (Rs, Gs, Bs) of tristimulus values (Rt, Gt, Bt) of the ambient color determined, and its tristimulus values with ambient color (Rt, Gt, Bt) are recorded as " tristimulus values of aim colour ".For example, in the sRGB space, tristimulus values (Rs, Gs, Bs) are defined as making that the geometric distance between the sRGB value (Rt, Gt, Bt) of tristimulus values (Rs, Gs, Bs) and ambient color is below 1 or 1.When adjusting to 1 or 1 when following at the aberration in the sRGB space, in fact color looks it is same color.Be noted here that because the sRGB value is expressed as digital value (that is, 0 to 255 integer under the situation of 8 bits), so obtained the tristimulus values (Ri, Gi, Bi) of limited aim colour.The set of the tristimulus values of aim colour (Ri, Gi, Bi) comprises the tristimulus values (Rt, Gt, Bt) of ambient color and the tristimulus values (Rs, Gs, Bs) close with ambient color.
At step S5, treatment facility 101 reads out in the tristimulus values (Ri, Gi, Bi) of one group of aim colour determining among the step S4 from recording unit.
In step S6, treatment facility 101 is not repeatedly selected three kinds of colored particles from specified colored particles among step S3, with (hereinafter as the colored particles that will determine formula ratio, be also referred to as " target colored particles "), and from recording unit, read the tristimulus values of target colored particles.Selected three kinds of target colored particles are defined as colored particles 1, colored particles 2 and colored particles 3, and corresponding tristimulus values are defined as (Rj, Gj, Bj) (j is 1,2 or 3).
In step S7, the tristimulus values of three kinds of target colored particles that use is read in step S6, treatment facility 101 obtain and the formula ratio of the target colored particles that the tristimulus values (Ri, Gi, Bi) of record-playback aim colour are used (according to the weight of every kind of colored particles shared ratio (weight percent) in the gross weight of colored particles).When mixing three kinds of colored particles (being colored particles 1, colored particles 2 and colored particles 3) in the coating composition that forms usefulness at colored pattern, the formula ratio of every kind of colored particles should be as follows: mass percent x% (colored particles 1), mass percent y% (colored particles 2) and mass percent z% (colored particles 3).Here, x+y+z=100.The average particle diameter of supposing colored particles is that 0.5m is to 1mm.Because particle dia is greater than wavelength of visible light, so proportional by the area that mixes the spot that color that three kinds of colored particles obtain and colored particles form.When the proportion of three kinds of colored particles of hypothesis much at one the time, think to have the additive mixture of colors characteristic.Thereby the equation 1 below setting up is to equation 3.
Ri=xR1+yR2+zR3... (equation 1)
Gi=xG1+yG2+zG3... (equation 2)
Bi=xB1+yB2+zB3... (equation 3)
These equations are simultaneous equation, and wherein, Ri, Gi and Bi are constants, and Rj, Gj and Bj (j is 1,2 or 3) are coefficients, and x, y and z are variablees.Therefore, by x, y and the z that obtains from above-mentioned simultaneous equation, treatment facility 101 can be determined the formula ratio of colored particles 1, colored particles 2 and colored particles 3.Should be noted that it is known by numerical evaluation separating of linear simultaneous equation formula being carried out Calculation Method, thereby omit the description of known method.
In step S8, whether the formula ratio (x, y, z) of three kinds of target colored particles that obtain among the treatment facility 101 determining step S7 can be applied to the manufacturing that multicolor patterns forms the coating composition of usefulness.For example, when the formula ratio that is calculated is negative value, in fact can not produce the coating composition that multicolor patterns forms usefulness.Thereby whether the result of treatment facility 101 determining step S7 is included into following conditions.Then, only when not satisfying any one condition, process just enters step S9; Otherwise step enters step S10.
Among first condition: x, y and the z any one is negative value.
Second condition: at L
*a
*b
*In the color space, with the aberration of ambient color greater than 5.
The 3rd condition: a kind of formula ratio of colored particles is more than 90%.
The 4th condition: a kind of formula ratio of colored particles is below 5%.
During above the result of step S7 is included in the condition any one, use selected three kinds of colored particles can not form the target multicolor patterns.More specifically, when satisfying first condition, can not produce the coating composition that multicolor patterns forms usefulness as described above.
When satisfying second condition, the color of target multicolor patterns looks different with ambient color.In XYZ space or sRGB space, relation is according to the change in location in the space, so need to use the L that is suitable for human sensation between the aberration of geometric distance and human sensation
*a
*b
*Distance in the space is carried out and is judged.Thereby, for the color of multicolor patterns and ambient color being looked different situation gets rid of, second condition is defined as, convert the tristimulus values (Ri, Gi, Bi) of aim colour and the tristimulus values (Rt, Gt, Bt) of ambient color to L respectively
*a
*b
*Whether the aberration that obtains after the value is greater than 5.L
*a
*b
*Aberration is that two kinds of colors below 5 look it is identical color in the color space.Thereby, in this specification sheets, will be at L
*a
*b
*Be that color below 5 is called " with ambient color identical color " with the aberration of ambient color in the color space.
When satisfying the 3rd condition, multicolor patterns becomes dull, thereby is not preferred design aspect.In addition, when satisfying the 4th condition, in multicolor patterns, can not recognize spot.
In step S9, x, the y that treatment facility 101 will be determined in step S7 and z be recorded in about information (specifying the information of three kinds of colored particles) with the related colored particles of x, y and z.
In step S10, treatment facility 101 judge whether to from specified N kind colored particles among step S3, repeatedly do not select three kinds of colored particles might make up and carried out the processing of step S7 to S9.When residue does not also have treated combination, handle and return step S6.Then, determine a combination except the combination of having handled, make this combination then through the processing of step S7 to S9.When residue does not also have treated combination, handle entering step S11.Thereby, can determine to reproduce the combination of colored particles of tristimulus values (Ri, Gi, Bi) of an aim colour and the formula ratio of this combination.
In step S11, treatment facility 101 judges for all aim colours of determining among the step S4 whether carried out the processing of step S6 to S9.When residue does not also have the aim colour of processing, handle and return step S5.The aim colour of selection except treated aim colour makes this aim colour through the processing of step S6 to S9 of associating then.When not having residue also not have the aim colour of processing, processing finishes.
Thereby, can determine the formula ratio of the color of base material, three kinds of colored particles and colored particles.Then, coating can be reproduced the coating composition of base material color.Further apply by will in determined formula ratio, determined colored particles mixing the coating composition that the multicolor patterns that produces forms usefulness with carrier components to base material.Thereby, can form the multicolor patterns that is in harmonious proportion with ambient color and film.Should be noted that the mass ratio of carrier components and all coloring particle is appointed as carrier/colored particles=60/40 in 70/30 scope, normally 65/35.In addition,, selected to have the color of the color (seeing step S2) of the tristimulus values identical in the above as base material with the tristimulus values of ambient color.But, can determine the color of base material by the several different methods of describing later.
Described embodiments of the present invention above, but the present invention is unqualified in above-described embodiment.
For example, about in step S1, obtaining the method for colouring information, when building that has applied multicolor patterns etc. is in programming phase or design phase, from schema or cad data, can obtain the tristimulus values of ambient color.When not being when directly from schema or cad data, obtaining the tristimulus values of ambient color, by color figure number (if known) the corresponding color card of measurement with ambient color, can be to obtain tristimulus values with top identical mode.When in cad data, comprising the data that relate to ambient color, can calculate tristimulus values by carrying out arithmetic processing.In addition, though with top to compare accuracy low, part that can be by will having applied multicolor patterns and a plurality of color cards relatively (that is, select under visual observation with this part the proximate color card of color) be determined ambient color.
About in step S2 to the determining of base material color, can be with the color of identical with ambient color or close with ambient color color as base material." color identical with ambient color " refers at L
*a
*b
*In the color space with the aberration of ambient color in the color below 5.In addition, " color close with ambient color " refers at L
*a
*b
*Be greater than 5 with the aberration of ambient color in the color space and be color below 10.In this case, consider the material cost of the coating composition that forms base material and the workability of coating, the color close with ambient color can be defined as the color of base material.For example, by using colourity and brightness with respect to the slight color that changes of ambient color, can easily discern films multicolor patterns forms superincumbent part.
Can be by brightness is increased so that its projecting a little color or colourity reduced so that it is lower than the color that ambient color is determined base material, can be reduced in the amount of wanting the blended tinting pigment in the colored coating composition of formation base material then.Can suitably adjust the brightness or the colourity of base material.For example, in order to adjust brightness, can be with L
*a
*b
*L in the color space
*Only increase by 5 to 10.Perhaps, not with L
*Value defined is under the situation of constant value, can be according to L on every side
*Value changes the L that will increase
*Value.For adjusting colourity, and with L
*Value is increased to the L of projecting color
*Value is opposite, can be with L
*C
*C in the h color space
*Value only reduces by 5 to 10.The colourity of base material can be according to C on every side
*Value changes.
In addition, at L
*a
*b
*The color space or L
*C
*It is preferred using tristimulus values in the h color space, because obtained the sensation approaching with the sensation that comes from visual observation.Here, can be with at L
*a
*b
*The color space or L
*C
*Tristimulus values in the h color space convert the sRGB value to, as the data layout in the sRGB space.
The simultaneous equation of determining the formula ratio of colored particles is not limited to the equation 1 to 3 that uses the sRGB value, the L that can also use the sRGB value to change
*a
*b
*The simultaneous equation of value.In this case, can be by having at L
*a
*b
*Aberration with ambient color in the space is that aim colour is determined simultaneous equation in the definitions of color below 1.Because L
*a
*b
*The space to visual observation feel be fit to, so use L as described above
*a
*b
*Value is preferred.
Numerical value in second, third and the 4th condition is not limited to above-described numerical value, and can determine according to circumstances.For example, can so change second condition, make " at L
*a
