Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic product color matching system and method for designing a colorant for a resin so as to obtain a hue required by a customer.

[0002]

2. Description of the Related Art Coloring of general household goods, home appliances, OA products, automobile parts, building parts, etc. (collectively referred to as plastic products) molded from plastic is performed by adding a resin colorant to a resin component (hereinafter referred to as a resin component). , A base resin) can be achieved. A plastic product manufacturer or the like (hereinafter referred to as a customer) presents a hue sample having a desired color to a resin colorant supplier (hereinafter simply referred to as a supplier).

Therefore, in the prior art, first, a customer presents a hue sample to a supplier, and then the supplier designs (mixes) a colorant for the resin, and obtains the resin coloring obtained by the toning. The flow until the hue obtained from the agent is approved by the customer will be described with reference to FIG.

[0004] First, a color sample of a plastic product is determined at a customer (# 1). When toning a plastic product, the customer uses the hue sample to specifically present the hue of the plastic product required by the customer to the supplier. There are various types of hue samples, such as a colored plastic product sample, a paper sample, and a painted sample in which a metal piece is coated. This hue sample is used for transportation of trucks, etc.
The mail is delivered from the customer to the supplier, and a color sample arrives at the supplier (# 2). In some cases, a sales representative on the supplier side goes to get a hue sample.

When the hue sample arrives, the supplier arranges toning and starts toning (# 3). This toning operation refers to designing components such as coloring components such as dyes and pigments, dispersing aids, and additives, which are the basis of the hue. In the present invention, the recipe of the coloring components is determined. (Determining how much such coloring components are to be blended).

[0006] The toning operator determines a recipe based on the presented hue sample by using an empirical rule or a CCM device (computer color matching: a device that performs toning by computer simulation). (Toning end # 4).

[0007] After determining the recipe, the supplier prepares a small amount of resin colorant according to the recipe, and prepares a hue confirmation plate by injection molding or press molding (# 5). The prepared plate is transported by a truck or the like and delivered to the customer.

When the hue confirmation plate arrives at the customer (# 6), the hue is confirmed using the plate (# 6).
7). If the color of the plate matches the customer's requirements,
The hue is approved (# 8). Thereby, the recipe of the resin colorant is finally determined. If the hue does not meet the requirements, request the supplier to re-color and resend the hue sample. In this case, the procedure from step # 2 is repeated again.

[0009]

The problems in the above-mentioned prior art color matching system for plastic products are as follows.

That is, in order to present a hue sample, the hue sample is delivered from the customer to the supplier by transportation. Therefore, it is troublesome and troublesome to deliver the hue sample, and it takes time. The method in which the supplier's person goes to the customer side to collect the hue sample also takes time. This problem also occurs when a hue confirmation plate is delivered from a supplier to a customer. Further, in the case where the approval is not obtained in the hue confirmation, extra time is required for re-shipping the hue sample.

It is also conceivable that the supplier may use a hue confirmation plate that has been toned, but there is a slight difference in hue from the hue requested by the customer, and it is necessary to obtain the approval of the customer. difficult. Due to the design required by the customer, the hue on the existing hue confirmation plate rarely matches the customer's request as it is.

As still another conventional technique, a supplier converts a recipe for a resin colorant into data in a computer, transmits the data to a customer using communication means, and displays the data of the customer on a computer screen of the customer. A color transmission system for searching for a hue that meets the requirements is also known (Chemical Industry Daily, November 29, 2000).

According to this method, the labor of sending the hue sample can be omitted, but the method allows the customer to select from the hue prepared in advance on the supplier side, and it is possible to completely satisfy the request of the customer. Not something you can do. This problem is the same as the case where the supplier uses a hue confirmation plate that has been toned.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to simplify the procedure for distributing a hue sample and to adjust the color of a plastic product that can be adjusted to meet customer requirements. A color system and method are provided.

[0015]

According to the present invention, there is provided a plastic product color toning system according to the present invention, which converts hue data of a hue sample measured by a colorimeter at a customer's site.
A receiving unit that receives from a customer via a communication unit, using the received hue data, a computer simulation unit that designs a resin colorant, so that a hue of the hue sample is obtained, A display unit for displaying a hue obtained based on a simulation result in the computer simulation unit.

The operation and effect of the system according to this configuration are as follows. First, the hue data of the hue sample is transmitted from the customer via the transmission means, and received by the receiving unit on the supplier side. The hue data is obtained by measuring the hue of a hue sample with a colorimeter. The hue data is, for example, reflectance data for each wavelength using a predetermined light source, an index selected from the L * a * b color system, XYZ (Xx
y) Data such as an index selected from the color system and an index selected from the Munsell color system may be used. As transmission means,
For example, there is a mode in which data is transmitted using a network such as the Internet.

The supplier uses the received hue data to design the blending amount of the coloring components constituting the resin colorant. The coloring component is selected from one or more types,
The blending amount is designed for each coloring component.

The hue (real color image) is displayed on the display unit in order to confirm the simulation result by the computer simulation unit. What is obtained as a result of the simulation is hue data such as reflectivity. By displaying the hue data as actual colors, visual confirmation is performed. As the display unit, for example, a CRT or a liquid crystal monitor can be used.

According to the above arrangement, there is no need to send a hue sample from the customer to the supplier. What is sent from the customer to the supplier is the hue data. The hue data is obtained by measuring a hue sample with a colorimeter and can be identified with the hue sample.
Therefore, it is possible to provide a plastic product toning system capable of simplifying a procedure for delivering a hue sample.

Further, in the system according to this configuration, since the colorant for the resin is designed based on the hue sample presented by the customer, it is possible to perform the color matching that meets the requirement of the customer.

As a preferred embodiment of the present invention, there is provided an apparatus having a transmission unit for transmitting hue data calculated from a design result of the resin colorant by the simulation to a customer.

As a result of designing the colorant for the resin, a simulation result of which color component is mixed and in what amount (or ratio) is obtained. Then, hue data can be calculated from the simulation result. This calculation can also be executed by the computer simulation unit. The calculated hue data is transmitted to the customer. This transmission can also be performed using communication means such as the Internet.

According to this configuration, since the hue data obtained as a result of the toning is transmitted to the customer, it is not necessary to send out the hue confirmation plate. Therefore, also in this regard,
Further, the procedure can be simplified.

As another preferred embodiment of the present invention, there is a configuration in which the hue can be confirmed on a computer screen or a printer of the customer based on the hue data transmitted to the customer.

The customer can calculate and calculate the hue from the transmitted hue data, display the hue (real color image) on the computer screen of the customer, output the hue to a printer, and output the hue. You can check. From this hue, it can be determined whether to approve the hue.

In still another preferred embodiment of the present invention,
An apparatus including a plate forming apparatus (a resin molding machine or the like) for forming a hue checking plate based on a design result of the resin colorant by the simulation is exemplified.

As described above, the hue confirmation at the customer site can be performed by comparing the transmitted hue data with the hue data obtained by measuring the color of the hue sample. However, there are cases where the hue displayed by the computer screen or the printer is slightly different from the actual hue. This is because the hue range that can be expressed by the computer screen or the printer may not be able to cover the hue range required by the customer.

Therefore, based on the design result of the colorant for the resin, a hue confirmation plate is actually prepared,
The hue can be confirmed more reliably.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a color matching system for plastic products according to the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating an outline of a system flow. FIG. 2 is a block diagram showing a configuration of a main part of the system.

In FIG. 2, reference numeral 1 shows a system at the customer's site, and FIG. 2 shows a system at the side of the resin colorant supplier. Both systems use the Internet 3 as a communication means.
Connected through. The communication means may be a network other than the Internet, such as a LAN or WAN.

The customer system 1 is mainly a personal computer
It comprises a (computer), and a CPU 10, an input unit 11, a display unit 12, a printer 13, a transmission / reception unit 14 (transmission unit + reception unit), and the like are connected via a data bus. The input unit 11 includes a keyboard, a disc insertion unit, and the like, and receives hue data measured by the colorimeter 15. The display unit 12 includes a CRT and a liquid crystal monitor. Thus, the hue based on the input hue data can be displayed on the monitor screen. The printer 13 can print out a hue based on the input hue data. The transmission / reception unit 14 transmits and receives hue data. Of course, data other than hue data can be transmitted and received.

The colorimeter 15 is a device for obtaining hue data from a hue sample of a customer. For example, a spectrophotometer can be used as the colorimeter 15. The hue sample is selected according to the purpose, such as a colored plastic product sample, a paper sample printed on paper, a painted sample printed on paper or a metal piece or a plastic plate, etc. Is mentioned. The present invention is not limited to a specific form of hue sample.

In the color measurement by the colorimeter 15, the color
In the visible light region of 700 nm, the reflectance at each wavelength is measured in steps of about 1 to 10 nm. The obtained reflectance data corresponds to the hue data in the present invention. This hue data is based on JIS
An index based on the L * a * b color system defined by Z-8729, XYZ (Xx) defined by JIS Z-8701
y) Data converted into an index based on the color system, an index based on the Munsell color system defined in JIS Z-8721 may be used as hue data.

The hue data obtained by the colorimeter 15 as described above is input into the personal computer via the input unit 11. The hue data may be input using a keyboard or may be input via a recording medium such as a floppy (registered trademark) disk. The colorimeter may be connected to the personal computer via an interface so that the hue data is automatically transmitted from the colorimeter to the personal computer. The type of the colorimeter 15 can be arbitrarily selected from commercially available types such as a bench top type and a handy type portable type.

The transmission of the hue data by the transmitting / receiving unit 14 is as follows.
For example, it can be transmitted by e-mail. As described above, the format of the hue data to be transmitted may be reflectance data at each wavelength or index data according to each color system.

Next, the system 2 on the resin colorant supplier side
Will be described. The system 2 includes a CPU 20, a computer simulation unit 21, a database 2
2. The transmission / reception unit 23 (transmission unit + reception unit), display unit 24, input unit 25, storage unit 26, and the like are connected via a data bus. The computer simulation unit 21 and the database 22 are functions of the CCM device 30.

The CCM device may be constructed by integrating the functions of the personal computer, the simulation section 21 and the database 22, and this is indicated by reference numeral 30 'in FIG.

The CCM device 30 has a database 22
It also has the function of measuring the color components and the compounded colorant for resin in order to obtain the data registered in the hue. The hue measured by the CCM device 30 and the hue measured by the customer's It is important that no deviation occurs. If the deviation is large, even if the color difference between the hue data obtained by the CCM device 30 and the hue data transmitted from the customer is apparently small, the actual hue will be largely shifted, and the customer will be satisfied. This is because the result of performing the operation cannot be obtained. Therefore, prior to toning, when a standard hue sample is measured with the colorimeter 15 at the customer site and the CCM device at the supplier, calibration is performed so that the color difference (ΔE) between them becomes 1 or less. There is a need. If ΔE exceeds 1, it is difficult to match the color tone of the resin colorant proposed to the customer with the customer's requirements.

The transmitting / receiving section 23 can receive hue data transmitted from a customer. Of course, information other than hue data can also be received.

The computer simulation unit 21 (hereinafter, simply referred to as a simulation unit) designs the blending amount of the coloring component based on the hue data transmitted from the customer. The function of the simulation unit 21 is as follows.
The purpose is to select the coloring components and to design the amount of the coloring components so as to obtain the hue desired by the customer. Therefore, many types of coloring components and their reflectance data are registered in the database 22 in advance. The registration of the data is performed via the input unit 25. The input unit 25 includes a keyboard, a disc insertion unit, and the like.

The color component is selected based on the data received by the transmission / reception unit 23. The selection may be made by the operator based on experience, or may be automatically selected by the function of the simulation unit 21. You may make it. The same applies to the blending amount.

The simulation unit 21 can calculate hue data based on the selection of one or more coloring components and the designing of their respective blending amounts. Since the data of the coloring components are registered in the database 22 together with the reflectance data (reflectance for each wavelength), the reflectance as a result of blending can be calculated based on the data.

Here, the significance of the “design of a resin colorant” performed by the simulation unit 21 will be described. When the simulation unit 21 determines the type and the amount of the coloring component, the determination and the calculation of the hue data and the data for hue display from the determined data are defined as the concept of “design”. included. When the operator determines the type and the amount of the coloring component, the concept of “design” includes calculating hue data and data for hue display from the determined data.

For example, when the hue data transmitted from the customer is the reflectance data for each wavelength, the reflectance data obtained by designing the simulation unit 21 and the transmitted reflectance data are compared. Can be contrasted. In order to visually express the comparison of the data, the data can be displayed on the display unit 24. The display unit 24 displays C
It is composed of an RT and a liquid crystal monitor.

The simulation section 21 can calculate a hue from hue data (reflectance data for each wavelength and index data for each color system). By displaying this hue on the display screen (computer screen) of the display unit 24, the hue can be visually confirmed.
In addition, it can be visually confirmed by printing out with a printer.

<Flow of Toning Operation> Next, the flow of the toning operation in the plastic product toning system according to this embodiment will be described with reference to FIG.

First, prior to the toning work, a hue sample of a plastic product is determined at the customer (# 10).
This hue sample is used as a sample for hue confirmation. Next, the colorimeter 15 measures the color of the hue sample. The color measurement by the colorimeter 15 is performed by the colorimeter 15 of the customer.
Alternatively, the sales representative of the supplier may visit the customer, and the representative may perform the color measurement. In this case, the person in charge brings the colorimeter 15 to the customer and performs colorimetry. The hue data of the hue sample can be obtained by the color measurement by the colorimeter 15 (# 11).

Next, the hue data is transmitted to the supplier via communication means such as the Internet (# 12). The supplier receives the hue data at the transmission / reception unit (# 13). Upon receiving the hue data, the toning operator of the supplier starts toning work (# 14). This toning operation is performed by the CCM device 30.

As described above, the reflectance data of each coloring component is registered in the database 22 of the CCM device 30, and the physical properties of the coloring component such as heat resistance, weather resistance, chemical resistance and the like, and cost. , Legislation, safety and other factors,
The type and amount of the coloring component are designed. Information on the type and grade of the resin (base resin) used by the customer is also input, and information on the number of coloring components is also input. The selection of the type and the amount of the coloring component is performed based on the transmitted hue data. However, this step may be automatically selected by the simulation unit 21,
The toning operator may make the selection based on experience. When data necessary for toning is input, the calculation is performed by the simulation unit 21 and the simulation result is displayed on the display unit 24. In addition, the degree of coincidence between the hue sample (sent hue data) and the simulation result is displayed by a reflectance curve, a color difference (ΔE), and a color coordinate (a hue shift direction), and the magnitude of the shift is confirmed. Can be. Further, indices based on the L * a * b color system, the XYZ (Xxy) color system, and the Munsell color system are also calculated, and the results are displayed. If the degree of coincidence is low, the computer simulation is continued by increasing the number of coloring components or changing to another type of coloring component. The simulation is continued until the degree of coincidence increases. This is because if the simulation is finished with a low degree of coincidence, the level required by the customer cannot be obtained.

When the toning operation is completed, the toning operator registers the obtained recipe (the types and amounts of the coloring components constituting the resin colorant). The data is stored in the storage unit 26 (memory, hard disk, or the like) of the system 2. When the toning is completed, a hue check operation with the customer is started. Regarding the hue confirmation work, various embodiments can be considered as follows.

<First Embodiment> After the toning work is completed,
The supplier informs the customer that the toning has ended.
The customer requests the supplier to prepare the resin coloring agent having the above-mentioned composition in order to confirm the hue using an injection plate or a press sheet. Adjustment refers to producing a small amount of resin colorant for testing.

The supplier prepares a resin colorant based on the customer's request and sends it to the customer. Alternatively, a predetermined amount of the resin colorant is mixed with the base resin to prepare an injection plate or a press sheet, which is sent to the customer. The customer uses the injection plate or press sheet created as described above to determine whether or not the hue of the compounded resin colorant matches the customer's requirements. The injection plate and the press sheet may be created by the customer.

<Second Embodiment> After the toning work is completed,
The supplier transmits the hue data obtained as a result of the simulation using communication means such as the Internet (# 15). The hue data includes at least a color difference (ΔE) from the hue sample presented by the customer, a color coordinate indicating a hue deviation direction from the hue sample, and a reflectance curve of the hue sample and the selected resin colorant. One data is included.

The customer receives the hue data (# 16),
From these color difference (ΔE), color coordinates, and reflectance curve, it is determined whether or not the hue of the resin colorant matches the customer's requirement (# 18). If the result of the hue check is NG,
Ask the supplier again for toning. If the result of the hue confirmation is OK, the approval is granted (# 19).

It is to be noted that the customer can check the hue using the plates and sheets described in the first embodiment according to the purpose of use of the plastic product.

<Third Embodiment> After the toning work is completed,
The supplier transmits reflectance data at each wavelength as hue data to the customer (# 15). The customer receives the hue data (# 16). The customer compares the hue obtained from the hue data measured from the hue sample prior to the toning with the hue obtained from the reflectance data at each wavelength transmitted from the supplier. As a result of the comparison, it is possible to determine whether or not the two match the customer's request based on the degree of coincidence between the two. For this purpose, the hue obtained from the transmitted reflectance data is displayed on the display unit 12 using the real color image display function of the personal computer (# 17), and the determination is made. Also, the printer 13 has a hue (real color image).
May be printed to make the determination.

It is to be noted that the customer can check the hue using the plates and sheets described in the first embodiment according to the purpose of use of the plastic product. In the hue confirmation, it is also possible to determine whether the hue of the resin colorant matches the customer's requirement based on the color difference (ΔE), the color coordinates, and the reflectance curve described in the second embodiment.

When hue data is transmitted by communication over the Internet or the like to display hue on a computer screen (display unit) of a customer, the degree of coincidence between the actual hue and the hue on the computer screen is important. When displaying hue on a computer screen, there is a deviation from the actual hue due to the display technology of the computer screen.Therefore, in order to check the hue on the computer screen, the actual hue and the hue on the computer screen are displayed. The hue needs to be close.
Therefore, in order to prevent the hue deviation from becoming large, the hue is finely adjusted on the computer screen by using the screen color adjustment function. In the present invention, when the hue is confirmed on the computer screen, the hue of the hue sample is displayed on the computer screen after the fine adjustment of the hue, and the hue of the toned result is compared on the computer screen. I do. As described below, the comparison may be performed using prints output from a printer.

Also, when the hue data is transmitted by communication over the Internet or the like and the hue (real color image) is printed on the customer's printer, the degree of coincidence between the hue expressed by the printer and the actual hue is important. It is. Therefore, in order to prevent the hue deviation from becoming large, fine adjustment of the hue expressed by the printer is performed using the print color adjustment function. As a result, a reliable determination can be made.
