Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments, and that all other embodiments obtained by persons of ordinary skill in the art without making creative efforts based on the embodiments in the present invention are within the protection scope of the present invention.
Example 1:
referring to fig. 1 to 7, a high-speed accurate digital printing color allocation method includes the following steps:
a. Color information of an image to be printed is acquired, wherein the color information comprises RGB values and CMYK values, and an operator needs to acquire the color information when processing the image to be printed so as to carry out subsequent printing processing. To obtain accurate color information, the operator needs to obtain the RGB values and CMYK values of the image. First, an operator may obtain RGB values of an image through related functions in image processing software or programming language. RGB values are a representation method based on three basic colors of red, green and blue, and the value range of each color channel is usually 0 to 255. By acquiring the RGB value of each pixel in the image, the operator can obtain the color distribution of the whole image. Second, the operator also needs to acquire CMYK values of the image. CMYK values are a print color chart based on cyan, magenta, yellow, and black, commonly used in the printing industry. Similar to RGB values, the value range for each color channel is typically 0 to 100%. By acquiring the CMYK values for each pixel in the image, the operator can learn the color information that is required for the image during the printing process. After the RGB values and CMYK values of the image are obtained, the operator can analyze and process these data. For example, the operator may calculate the average RGB values and CMYK values of the image to obtain the overall color propensity. In addition, operators can adjust the colors of the images according to the needs, such as brightness, contrast and saturation, so as to ensure that the final printing effect meets the expectations;
b. According to the collected color information, the ink consumption of each color is calculated, and first, an operator needs to collect the color information. This can be accomplished by using a color sensor or scanner or the like. These devices can measure the color of the object surface and convert it into a digital signal. Next, the operator needs to process and analyze the collected color information. This may be accomplished using computer software or programming language. The operator may use an image processing algorithm to extract the color features and convert them into a computable value. Once the operator has obtained a numerical representation of each color, the operator may begin calculating the ink usage. The calculation of the ink usage can be performed according to different requirements and demands. One common method is to determine the ink usage based on the saturation and brightness of the color. The higher the saturation, the brighter the color will generally require more ink to achieve the same result. The operator also needs to consider other factors such as print quality and print speed when calculating ink usage. If a higher print quality is desired, the operator may need to increase the ink usage to ensure accurate reproduction of the colors. And if a faster printing speed is desired, the operator may need to reduce the ink usage to reduce the printing time. Finally, the operator can apply the calculated ink usage to the actual printing process. This can be achieved by adjusting the amount of ink in the ink cartridge or ink bag of the printer. By precisely controlling the ink usage of each color, operators can ensure that the printed color is consistent with expectations and improve printing efficiency and cost effectiveness;
c. according to the calculated ink amount, color matching is performed, and first, it is necessary to determine what color is to be matched. This can be determined by reference to the design script, the sample, or by communication with the customer, and then, based on the shade of the desired color and the ink concentration, the desired ink usage can be calculated. This can be done by using the ink quantity calculation formula or referencing the instruction provided by the ink manufacturer, and then secondly, a test strip print test needs to be performed on the print paper before starting to dispense the color to ensure the smoothness and accuracy of the print head, and then the corresponding ink is added to the ink reservoir according to the dominant hue of the desired color. The amount of ink can be precisely controlled by using a dropper, an injector or other tools, and finally, color matching can be performed according to the calculated amount of ink, so that the required color effect is obtained;
d. The process of printing the prepared colors through the digital printing equipment is a complex and fine work. First, the required ink and printing paper need to be prepared to ensure the accuracy and consistency of the selected color. And then, using professional digital printing equipment to input the prepared colors into a computer system one by one. These devices typically have high precision inkjet heads or nozzles that are capable of precisely ejecting ink of a desired color, and during printing, a computer system controls the movement trajectory and ejection speed of the inkjet heads or nozzles according to preset patterns or design requirements. In this way, the ink can be sprayed onto the fabric or other print medium in a predetermined manner to form a desired pattern or image. In order to ensure the printing quality, printing is usually performed for a plurality of times, colors are adjusted and optimized for each printing to achieve the best effect, and in addition, the digital printing equipment is also provided with an advanced control system and a sensor, so that various parameters in the printing process, such as the flow rate, the jet pressure, the temperature and the like of the ink can be monitored in real time. Precise control of these parameters is critical to ensuring print quality and color accuracy. Meanwhile, the digital printing equipment also has the functions of automatic cleaning and maintenance, and can regularly clean the ink-jet head or the nozzle so as to keep a good working state.
Referring to fig. 2, the image information to be printed is acquired by using a spectrometer or other devices to obtain spectral data of a target color, where the spectrometer is a special instrument for measuring spectral characteristics of light. It is capable of splitting light into light rays of different wavelengths and measuring the intensity of light at each wavelength. In this way, the spectrometer can provide detailed spectral data of the target color, and when the image information to be printed is collected, the spectrometer irradiates the target object and receives reflected or transmitted light. The spectrometer then converts the light signals into digital signals and the digital signals are analyzed and processed by a computer, the spectral data including information including wavelength, intensity, etc., the wavelength in the spectral data being the frequency or color of the light. Different wavelengths correspond to different colors, for example, red light having a wavelength of about 630 nanometers and blue light having a wavelength of about 450 nanometers. By measuring the wavelength of the target color, the operator can determine its specific hue and saturation, and the intensity in the spectral data refers to the brightness or intensity of the light. It shows the light energy distribution of the target color at different wavelengths. By measuring the intensity of the target color, the operator can understand the brightness and contrast, and by using a spectrometer or other device to obtain the spectral data of the target color, the operator can obtain important information about the target color, such as parameters of wavelength and intensity. This information is important for color matching and quality control during printing.
Referring to fig. 3, the spectral data is converted into RGB values, and the conversion is performed using the correspondence between the spectrum and RGB, and this process uses the correspondence between the spectrum and RGB to perform conversion by mapping the spectral data to the corresponding RGB values, for example, the red light corresponds to a wavelength range of 620-740nm, the RGB values are (255, 0), and the red light is used as an example. The wavelength range of red light is typically between 620-740 nanometers. From this range, the operator can convert the corresponding spectral data into RGB values. In this case, the RGB value of red light is (255, 0), and this conversion method can be applied to spectral data of other colors. The spectral data for each color has its specific wavelength range and corresponding RGB values. By associating the spectral data with RGB values.
Referring to fig. 4, the ink usage is to select a proper basic color according to the characteristics of the target color and the application scene, and an operator needs to select a proper color curve as a color matching basis. The base colors are typically white or black, as they can be mixed with any other color to obtain the desired target color to determine the base color to other color ratio for subsequent color matching calculations, calculated using palette or color theory. The color palette is a tool which contains samples of different colors and can help operators to determine the proportional relationship between the different colors. Color theory provides a systematic approach for understanding the relationship and interaction between colors, and the operator needs to consider the brightness, saturation, hue, and other factors of the target color when determining the proportional relationship. These factors can be achieved by adjusting the mixing ratio of the base color and the other colors. For example, if the operator wants to obtain a darker target color, the operator can increase the proportion of black; if the operator wants to obtain a brighter target color, the operator can decrease the proportion of black and increase the proportion of white.
Referring to fig. 5, the color scheme is calculated according to RGB values of the basic color and other colors, and may be calculated by using methods such as weighted average, discrete sampling, etc., where the formula of the weighted average algorithm is as follows:
(Σw_i x_i)/(Σw_i), which is the most basic weighted average formula, where w_i is the weight of each value, x_i is each value, this formula represents the sum of all values multiplied by their corresponding weights divided by the sum of all weights, where w_i represents the weight of each value, and x_i represents each value. This formula represents the sum of all values multiplied by their corresponding weights divided by the sum of all weights. By adjusting the weights, we can control the relative proportions of the different colors in the color scheme, and the discrete sampling algorithm uses a different method to calculate the color scheme. First, we define an input sequence X, which contains all possible color values. We then use a threshold to determine whether the conditional probability density function value is met. Next, we calculate some parameters, including L, D and I, from the length N of the input sequence and the threshold. Finally, we use these parameters to generate a new sequence X' as a color scheme.
Specifically, the formula of the discrete sampling algorithm is as follows: x' =floor (l×range ()), l=int (n×i/D) +1, d=sum (I) -n×i/N, i= [1if X > =threshold else 0for X in X ], wherein floor () function is used to round down, and range () function is used to generate random numbers. By multiplying L by a random number and rounding down we can get a new color value as part of the color scheme. The calculation of L is based on the length N of the input sequence, the threshold value threshold, and some other parameters.
Referring to fig. 6, the color scheme is evaluated and optimized to adjust the calculated color scheme, such as contrast, saturation, etc., first, the contrast refers to the degree of brightness difference between different colors. By adjusting the contrast in the color scheme, the operator can make the image or design more vivid. For example, increasing contrast may make black darker, white whiter, thereby enhancing the sharpness and stereoscopic impression of the image. Conversely, reducing the contrast can make the image softer and milder, and is suitable for some designs that require creating a warm atmosphere. Next, saturation refers to the vividness of the color. By adjusting the saturation in the color scheme, the operator can make the color more vivid or soft. The increased saturation can make the color brighter and fuller, and is suitable for designs requiring highlighting or attracting eyeballs. The color can be softer and more natural by reducing the saturation, the color can be suitable for the design of creating comfortable feeling or soft atmosphere, and the color can be adjusted according to the actual demand and the effect requirement so as to achieve the best visual effect, for example, the color tone can be adjusted, and the whole color matching is biased to the cold color tone or the warm color tone so as to accord with the specific theme or emotion expression. Brightness can also be adjusted to make the image or design brighter or darker to accommodate different light conditions or scene requirements.
Referring to fig. 7, the blended color is printed by a digital printing device to output the final color scheme in a specified format, such as Mengtai, JSON, CSS, and the operator needs to print the blended color by a professional digital printing device. This process requires precise control and manipulation to ensure that the final color scheme can be output in a specified format, such as Mengtai, JSON, CSS, etc., and that the operator is required to input the formulated color data into the digital printing apparatus. This usually involves setting of RGB values or CMYK values of colors, which are directly applied to the production process of digital printing, and then the digital printing apparatus prints according to the input color data. In this process, the device will precisely control the amount and location of ink ejected to ensure that the printed color is consistent with the intended color, and finally, the operator will need to output the printed color effect in the specified format. This is typically accomplished by converting the color data into JSON, CSS, etc. formats. These formats can be conveniently read and applied by other systems or devices to achieve fast transfer and sharing of colors.
The using method comprises the following steps: the operator uses the spectrometer to accurately measure the target color to obtain the detailed spectrum data, the data contains the spectrum distribution condition of the target color, an important basis is provided for the subsequent color conversion, then the operator converts the spectrum data of the target color into corresponding RGB values, the RGB values are a common color representation mode and are composed of three basic color channels of red, green and blue, various different colors can be synthesized by adjusting the intensities of the three channels, then the operator determines the required basic color and color matching proportion according to the RGB values of the target color, the basic color is the main color in the color matching scheme, the color matching proportion determines the proportion of other auxiliary colors in the color matching scheme, and then the operator calculates the required color scheme according to the basic color and the color matching proportion, and the process needs to consider factors such as the contrast, the saturation and the like of the colors so as to ensure the visual effect of the color matching scheme.
Then, according to the actual situation, the operator adjusts the calculated color scheme. This may involve adjusting the brightness, contrast, etc. of the color to achieve a better effect.
And finally, outputting the final color scheme to digital printing equipment for printing operation. Thus, a printed product with good visual effect can be manufactured according to the calculated color scheme
