Definitions
- the invention relates to a learning process for the preparation of color formulations, which can be adapted in a few steps to a fixed color specification.
- the color tone which is produced by weighing the quantities of constituents specified in a color formulation, with respect to a predetermined target color shade with the smallest possible deviation.
- the formulation ingredients can be both colored in nature, such as color or effect pigments, as well as non-colored nature, including, for example, binders. Additives and solvents are understood.
- the aim of the toning of the batches is to adjust the color of the batch to the target color tone with as few tinting steps as possible, in the interest of economic efficiency. This adjustment is made by slight changes in the amounts of colored ingredients contained in the recipe and optionally by adding further colored Tönzu accounts in low concentrations.
- the adaptation step is not complete until an acceptable residual color difference has been reached between the color of the batch and the target color tone.
- the quality of the calculated recipes strongly depends on the standardization of all components of a mixed lacquer system and the constancy of the application parameters.
- the optical material parameters are determined only once for the particular pigment in the binder system.
- the effect matrix is a decisive factor for the quality of the hue adjustment. It is, as already described above roughly for the process of DE 197 20 887 A1, set up by means of experimentally determined calibration scales of the reflection parameters of the pigments underlying the recipe and also stored in the recipe database. Therefore, the effect matrix describes the coloristic effect of the individual recipes in the Reflexicnsraurn or color space angle-dependent with varying
- the object of the invention is therefore to provide a method for color recipe calculation, which also takes into account the fluctuations of the raw materials and starting materials and the effects of process fluctuations and thus the residual color difference to the target color tone while reducing the number
- the optical material parameters are adapted to each one
- the pigment-specific and wavelength-dependent material parameters of the scattering and absorption coefficients must be determined experimentally by means of a calibration scale in a manner known to the person skilled in the art.
- Absorption coefficient is additionally to determine the phase function.
- a stationary or portable goniospectrophotometer with symmetrical or asymmetrical measurement geometry can be used.
- the area of the observation angle to be covered depends on the particular approximation used for the radiative transfer equation. It can both devices with lighting and with
- Observation modulation can be used.
- the amounts of the recipe components (N pigments) for a given recipe are slightly varied by their nominal concentration and the associated coloristic effect in the reflection space or in the ClELab space is calculated as an angle (M angle) using the optical material parameters.
- M angle the effects of changes in concentration of constituents whose material parameters are known can be calculated as effects in color space or reflection space.
- the information content of the effect matrix can now be used immediately or later at any given time to tint a reference recipe to a target point deviating from the reference point. This target point should not be so far away from the reference point that the scope of the approximation used is exceeded.
- the hue changes can then be represented as differentials dL7dc da * / dc "db * / dc, and dL7dc" dC * / dc "dH7dc.
- the color tone changes can be detected as a function of the aforementioned process parameters.
- color-relevant information is understood here and in the following as meaning all information and measured values which comprise color tone changes caused by respective quantity or batch changes in the continuous process, and the entirety of the dependencies of the color tone changes in the form of differentials of the effect matrix to be created therefrom summarized under this term.
- This information can either be collected in accordance with this invention in addition to existing processes. You can but preferably obtained from existing testing processes. For example, such information may be obtained in routine, ongoing quality control.
- the color-relevant information is particularly preferably obtained from laboratory tests, quality tests, incoming inspections or operating samples.
- a dyeing system means any combination of at least two different pigments and / or binders
- a dyeing system comprises a large number of different colored or effect pigments containing compositions, which may be termed either a base or pigment paste.
- the number and variety or selection or combination of the pigment components are not subject to any restriction and can be adapted to the respective requirements, for example, such a dyeing system can comprise all the pigment components of a standardized mixed-lacquer system underlie.
- Effect pigments are to be understood as meaning all pigments which have a platelet-like structure and give a surface coating special decorative effects.
- the effect pigments are, for example, all effect pigments which can usually be used in vehicle and industrial coating or in ink and dye production.
- Examples of such pigments are pure metal pigments such as aluminum, iron or copper pigments, interference pigments such as titanium dioxide coated mica, iron oxide coated mica, mixed oxide coated mica, metal oxide coated aluminum, or liquid crystal pigments.
- the coloring absorption pigments are, for example, customary organic or inorganic absorption pigments which can be used in coating chemistry.
- organic Absorbent pigments are azo pigments, phthalocyanine, quinacridone, and pyrrolopyrrole pigments.
- inorganic absorption pigments are iron oxide or lead oxide pigments, titanium dioxide and carbon black.
- pseudo pigments are those substances which are influencing the topology in terms of effect pigments, but are otherwise coloristically ineffective. They are preferably selected from the group of known fillers.
- the inventive method can be referred to as learning. In this way, it is also possible for the first time to greatly increase the accuracy of the process. Because the accuracy of the process is crucially dependent on the quality of the effect matrices.
- the effect matrices can be expanded with shade-relevant information from laboratory tests, quality checks, incoming inspections and operating samples.
- the effect matrices which were first determined during the preparation and production of a base shade or a color paste, are later extended by further parameters.
- This extension of the effect matrices is preferably done by shade relevant information obtained in the ongoing process by the measurement of hue changes depending on different amounts, application methods or batches. From this information, it is possible to determine the changes in the optical material parameters, which are ultimately included in the effect matrices.
- the process according to the invention can be used, for example, for the color shade of paints and printing inks or polymer dispersions.
- Fig. 1 is a schematic representation of the learning correction according to the invention (right) compared to the classical static stitching.
- a corrected hue is achieved by stepwise correction, which achieves an acceptable residual color difference with respect to the associated hue standard.
- stepwise correction As can be seen from the figure, according to the classical method, considerably more tinting steps are required to reach the target point than in the new learning method.
- a characteristic of the learning, dynamically updated method can be seen in the fact that even in the first tinting step a very close approach to the target point succeeds due to the high quality of the effect matrices.
