Description

Color Management Method of Colored Plastic Product

The present invention relates to a method for color management of plastic colored products and the samples used therein.

Color is a very important factor in the successful marketing and sales of most retail items. Color management for acceptable hue, properties and performance is a problem encountered regardless of colored substrates such as textiles, leather, plastics, paper, paints, inks and the like. Extensive color management is particularly needed if a particular retail item is supplied from multiple vendors, includes a variety of substrates, or must be manufactured with accurate or similar colors for multiple substrates.

In particular, unlike fibers or paints, in the case of plastics, it is very difficult to accurately compare colors through the naked eye or a measuring device unless the injection or extrusion molded product has a certain thickness and area. Therefore, in general, colored plastic raw materials are injected or extruded in the same manner as the final product presented by the customer to visually compare colors, or manufactured with standard test pieces to compare colors through visual or measuring instruments. Doing. In other words, it is not possible to compare colors in raw materials such as paints and fabrics, but can be compared after manufacturing the final product or a test specimen of a certain size. It has to go through several times, and this causes a problem that a lot of losses occur in the development period, development cost, etc. of the coloring product. And even if the customer wants to select the desired color from the already developed coloring products to improve this, it is impossible to transport all the 1,000 to 2,000 colors in the injection or extruded test specimens to a certain size to the customer's location It's work.

As a result, the plastics industry has no choice but to find the most similar color among existing developed products or develop new ones every time a customer requests a coloring product. In other words, it was a wasteful factor such as rising manufacturing cost and development period.

Therefore, there is a need to improve the color management method of conventional colored plastic products.

The present invention is to solve the problems of the prior art as described above, an object of the present invention is to provide a color management method of a plastic coloring product that can shorten the development period and reduce the cost.

Another object of the present invention is to provide a swatch for color management that is easy to carry and view and can contain more data than conventional swatches.

In order to achieve the above object, an aspect of the present invention comprises the steps of: a) creating a color database by classifying colors of a plastic product family comprising one or more plastic products; b) manufacturing a paint group having a color corresponding to the color database; c) forming a swatch in the form of a printed or electronic document expressing the colors of each of the paint groups; d) manufacturing a plastic product that matches the color selected from the swatch; e) contrasting the selected color with the color of the plastic product prepared in step d)

It provides a color management method of the plastic coloring product, including.

A second aspect of the present invention provides a color database by classifying colors of a plastic family including one or more plastic products and producing a paint group having a color corresponding to the color database, the colors of each of the paint groups. Provide samples in printed or electronic form.

Using the color management method according to the present invention can shorten the development period of the new plastic coloring product and reduce the development cost.

In addition, since the sample according to the present invention is easy to carry and view and can contain more data than the conventional sample, the sample can be efficiently and compatible with the world standard color system.

Hereinafter, the present invention will be described in detail.

One aspect of the present invention includes the steps of: a) generating a color database by classifying colors of a plastic family comprising one or more plastic products; b) manufacturing a paint group having a color corresponding to the color database; c) forming a swatch in the form of a printed or electronic document expressing the colors of each of the paint groups; d) manufacturing a plastic product that matches the color selected from the swatch; e) contrasting the selected color with the color of the plastic product prepared in step d)

It relates to a color management method of plastic coloring products, including.

The plastic product in the present invention means all plastic products that can be colored, for example, ABS, PC, PA6, PA66, PBT, POM, PVC, PE, EPS, PMMA, PS, SAN, ASA, PP, etc. However, it is not limited thereto.

Preferred examples of the plastic product are styrene resins (ABS, PC, PMMA, SAN, PBT).

The method of classifying the color of the plastic product family in step a) of the present invention is not particularly limited, and may be appropriately selected according to the type of color that may be colored on the plastic.

Preferred color classification methods include the Munsell Color System, the Ostwald Color System, the NCS Natural Color System, and the PCCS Color System. Among them, the NCS color system, which distinguishes the attribute of color into color and nuance, is easy to plan for human color.

After classification according to the color system as described above, it is preferable to measure and record the values of L (luminosity-brightness axis), a (red / green complementary axis), and b (yellow / blue complementary axis) for each color. Do.

Step b) of the present invention is to produce a group of paint having a color corresponding to the color database. The method of manufacturing the paint group is as follows. First, paints having the same or similar color as the plastic color in the database are prepared according to conventional paint coloring methods. Thereafter, measurement using a colorimeter or visual measurement by a color expert is used to determine whether the color of the plastic matches the color of the paint. In this case, the coincidence of color means that the color difference (ㅿ E) is less than 2 when the color of the plastic and the color of the paint are measured. If necessary, work may be performed to match the glossiness of the plastic with that of the paint.

Step c) of the present invention is to form a swatch in the form of a printed or electronic document expressing the colors of each of the paint groups. Each color is preferably represented in the swatches by applying paints having similar colors to those of the plastics, classified and applied by similar colors. In addition, the swatch may further include one or more elements selected from the group consisting of color component data, reflectance data, glossiness data, dye formulation, and dye specification for each color in addition to each color being represented. The specimen may be carried in the form of printed matter such as paper, and may be downloaded and used through the Internet or a portable storage device by electronic documenting it.

Step d) of the present invention is to produce a plastic product that matches the color selected from the swatch. In the case of the present invention, since the color is selected from a swatch made using the same paint as the color of the plastic coloring product in which the blending ratio of raw materials, dyes, pigments and other additives is determined, the plastic product of the desired color is produced with little trial and error. can do. The manufacture of the plastic product is generally possible by, but not limited to, known compounding methods.

Step e) of the present invention is to contrast the selected color with the color of the plastic product produced in step d). At this time, the method of contrasting the color may be both a contrast method using the naked eye or a contrast method using a color meter, it is preferable to use both methods in parallel.

Here, it is preferable to repeat the steps d) and e) if the color difference between the color of the plastic product and the selected color is 2 or more after contrasting the color as described above.

A second aspect of the present invention is to generate a color database by classifying colors of a plastic family including one or more plastic products, and to produce a color group having a color corresponding to the color database. It relates to samples in the form of printed or electronic documents.

Description of the sample in the form of a printed or electronic document according to the present invention has been described in step c) of the color management method and will be omitted.

As described above, using the management method of the plastic coloring product according to the present invention, it is possible to easily carry and read all the colors of the database plastic coloring product. In addition, since the use of a printed or electronic document swatch, such as paper, rather than a plastic injection or extrusion test specimen, it may include any color already developed or ready for development. Therefore, you can select the color you want from the color included in the swatch without customizing the color as in the conventional method, and the designated color is the color of the product that has already been formulated or can be developed immediately through simple test. Plastic colored products having a color can be provided.
