example 1

[0104] The proofing and production process of completely matching colors (complete matching refers to the color difference DE<system deviation selection value):

[0105] a. At S200, the incoming sample X is detected by the color measurement module, and the detected data are shown in Table 1:

[0106]

[0107] Table 1

[0108] b. At S300, enter the data into the "Color Database". At S400, the system finds a color through calculation according to the setting, and the color number is #1. The color data is shown in Table 2:

[0109]

[0110] Table 2

[0111] The system calculates the DE value of 1# color and target color:

[0112] DE=sqrt((64.102–64.300)^2+(69.465–69.813)^2+(-16.001-(-15.763))^2)=0.466

[0113] Since DE = 0.466 < 0.5, the color formulation is considered to be perfectly suitable for preparing the ink of the sample color.

[0114] c. At S500, prepare a sample according to the formula, and print the color block sample; then at S600, measure and compare the ...

[0124] Proofing and production process that cannot completely match the color but has a similar hue (DE> system deviation selection value):

[0125] a. At S300, the target sample Y is detected by the color measurement module, and the detected data are shown in Table 4:

[0126]

[0127] Table 4

[0128] b. At S400, after inputting the data into the "COMAT Color Database", a completely matching color cannot be found in the database, that is, no color formula with DE<0.5 can be found. At this time, enter the process S410, and the L, A , the B value gradually expands the search range (each time the range expands +-0.1), and then enters the process S420, until these three values ​​can match within a positive and negative range value. After searching according to the sample Y, search the data in this range and judge the color at the same time, at S450, get three formulas, they are:

[0129]

[0130] table 5

[0131] Calculate the DE, DL, DA, and DB values ​​of these three ...

Abstract

The invention discloses digital color matching and dyeing methods and color matching and dyeing systems for pure color dyeing of a fabric. The digital color matching method comprises the steps of pre-establishing the digital color matching system, obtaining the LAB value of the color of a target sample, searching for a color database, obtaining a recommended ink formula, comparing a formula and the like. The color matching system comprises a color measuring probe unit, a storage unit, a data processing unit and a multi-ink-path scanning and printing unit. The digital dyeing method comprises the steps of digital color matching, ink blending for ink-jet dyeing and fixed single-channel ink-jet dyeing. The digital dyeing system is mainly composed of the digital color matching system, an ink mixing module and a fixed single-channel digital ink-jet module. The methods and the systems have the advantages of a traditional dyeing process and digital printing at the same time, for example, the cleanness and rapidness are achieved, printed samples are completely matched with large-scale products in color, the color gamut is wide, the uniformity is very good, and the depth and hue are the same as those of traditional dyeing.

Description

technical field [0001] The invention relates to the technical field of fabric dyeing methods and related equipment, in particular to digital color matching, dyeing methods, color matching and dyeing systems for solid color dyeing of fabrics. Background technique [0002] With the continuous improvement of people's quality of life and the continuous improvement of modern technology, people have higher and higher pursuit of the color of fabrics. For the pure color dyeing of different fabrics, traditional dyeing techniques can be used for dyeing. , can also use a digital printer to print a single color. [0003] The traditional dyeing process of fabrics can be divided into two types: dip dyeing and pad dyeing according to the different contact methods between dyes and fabrics. Dip dyeing is to immerse the dyed fabric in the dye solution, and make the dye uniform through the circulation of the dye solution and the relative movement of the dyed object. The dyeing method of dyed ...
