Description

Method of tracing the source of mother color using sample spectrum

The present invention relates to a method of color identification, particularly a method of tracing the source of parent colors using sample spectrum.

As early as 2500 BC, dyes from natural plants, animals and mineral essences have been used. Before the British chemist W. Perkin (1838-1907) invented the first synthetic dye (mauveine) in 1856, all dyes Dyes are naturally derived from plants, animals and minerals, such as plant roots, bark, leaves, flowers, fruits or wood. The dye production method is through simple processing methods, such as pounding materials and grinding to make natural dyes, which are widely used in textile dyeing processing. The more common method is the dye bath method, that is, natural dyes are put into a large pot and mixed with Boil boiling water, put the textile fabric to be dyed and the fixing agent into another large pot, boil it, put it into the dye pot, take it out to dry and then wash it to complete the dye coloring. However, natural dyes have been passed down to modern times, and some people have begun to synthesize synthetic dyes using fossil resources, such as petroleum. Petroleum is fractionated into coal tar and made into synthetic dyes.

There are about 200 domestic dyeing factories and about 100 digital printing factories, 90% of which are small and medium-sized enterprises. Dyes are usually dissolved in water, and some dyes require mordants to make the dyes adhere to the fibers. In the fabric dyeing process, in the color matching step, the traditional dyeing process relies heavily on manual rules of thumb, which often requires multiple color chasing (color correction), resulting in the waste of a large amount of water resources, such as tens of thousands of tons of dyeing wastewater.

In the dyeing process, the dyeing company's laboratory usually provides the formula and process information, and then submits it to the dyeing factory to test dye according to the formula and process, and set the dyeing process parameters for mass production of the dyeing process. During the dyeing stage, it is found that the test sample has color difference, uneven color, ripples, color fixation rate that does not meet the color rate standard, or a combination of the above-mentioned defective products. The dyeing process needs to add steps such as rinsing and color replenishment to strengthen the defective products. situation, or directly scrap the defective products. The defective products produced during the dyeing process have a huge impact on production costs. Many process factors in the dyeing process will affect the color matching rate of the fabric after dyeing, such as dye concentration, auxiliary concentration, initial pH value, liquor ratio, main pump speed, belt wheel speed, heating rate, and holding temperature. , washing time, soaping heating rate, soaping temperature holding temperature, soaping time, etc. Moreover, in the traditional dyeing process, the average production of 1 yard of sample cloth requires the smallest size dye vat (3 kg of cloth) and consumes about 1 ton of water. For example: 20 kg of dark-colored (black, blue) dyed cloth It needs to use 6~7 tons of water, and the wastewater treatment fee is about NT$1,000/ton. If there is no wastewater treatment tank in the factory, the cost of outsourcing is as high as NT$10,000/ton. If steps such as rinsing and color replenishment are added, the wastewater The processing costs will continue to increase, making the traditional dyeing process expensive and burdening the industry. There is an urgent need to introduce intelligent color matching technology to solve the problem.

Based on the above problems, the present invention provides a method for tracing the source of a mother color using a sample spectrum and a method for color matching using a sample spectrum. The method performs a matching operation by matching the color data to a preset color gamut to further obtain the parameters of the master dye. Therefore, the color master dye parameters are selected. At least one of several dye source materials. Moreover, the masterbatch dye parameters can be used in formula calculations to obtain spectrum matching information, and further adjust color data based on the spectrum matching information.

Please refer to Figures 2A to 2D together, which are the identification system 1 used with the method of tracing the mother color of the sample spectrum according to the present invention. It includes a host 10 and an image capture unit 20. In this embodiment The host 10 is a computer host having a processing unit 12, a memory 14 and a storage unit 16 as an example, but is not limited thereto, and may also be a server, a notebook computer, a tablet computer or an electronic computer with basic computing capabilities. The devices are the host 10 referred to in the present invention, and the database 30 is established in the storage unit 16, but is not limited to this, and can also be an external storage unit of the host 10; the host 10 executes an operation program P through the processing unit 12 , and correspondingly establish a type of neural network 126.

In step S10, as shown in Figure 2A, the host 10 reads a sample image REF captured by the image capture unit 20, and the sample image REF is a captured image of a stained sample.

The host 10 executes step S12. Referring again to the second figure A, the host 10 measures the reference image REF, samples the visible light with wavelengths from 390 nm to 700 nm according to different bands, and obtains the multi-band color filter color data SP, as shown in the second figure.

In step S182, as shown in the second D figure, the host 10 will generate a color difference accuracy rate E based on the color data SP corresponding to the color master dye parameter DP and the reference image REF, for example: 0%~3.2%. In step S184, As shown in the second D figure, the host 10 sorts the dye source data DS. The sorting reference basis of the host 10 is the color difference accuracy E obtained in step S182. Therefore, in step S186, the host 10 sorts the dye source data DS according to the dyeing sample. Based on the sample image REF, select the dye source data DS with a lower color difference accuracy E, for example: less than 1%.

As shown in Figure 5B, the host 10 performs step S14. The spectrum matching information INFO obtained from the color gamut space is converted into the dye color gamut D1 of the corresponding dye. In step S144, as shown in Figure 5B, the host 10 converts the complementary colors contained in the spectrum matching information INFO of the dye color gamut D1 into a presentation method of the primary color ratio, that is, converts the complementary colors contained in the color chip spectrum information INFO1 The complementary color data INFO11 is converted into the primary color data INFO12, for example: gray is converted into 50% black and 50% white.
