Description
Technical Field
The application belongs to the technical field of true color fluorescent products, and particularly relates to a manufacturing method of a true color fluorescent product, a true color fluorescent product and a true color fluorescent artwork.
Background
The anti-counterfeiting colorless fluorescent ink is also commonly called as invisible ink, and is a special ink which emits visible light (400-800 nm) under the irradiation of light sources such as ultraviolet light (200-400 nm). The main component of the anti-fake colorless fluorescent ink is fluorescent pigment, which is a functional luminous pigment, and is different from common pigment in that when external light (including ultraviolet light) irradiates, energy of a certain form is absorbed, the energy is not converted into heat energy, photons are excited, and the absorbed energy is released in a visible light form, so that fluorescent phenomena of different hues are generated. The anti-counterfeiting colorless fluorescent ink forms various colors under the irradiation of ultraviolet light, and the luminescence phenomenon disappears after the irradiation of the light is stopped. The fluorescent particles in the anti-counterfeiting colorless fluorescent ink can generate a certain range of brightness and particularly clean colors, such as yellow, orange, red, crystal red, green, cyan and the like. The key to this effect is that the ink contains special color pigments that absorb energy in the uv range and convert this energy to longer visible wavelengths. The anti-counterfeiting colorless fluorescent ink has the characteristics of wide application in anti-counterfeiting printing, simplicity in implementation, low cost, good concealment, bright color, convenience in inspection, strong reproducibility, various color changes, capability of meeting the requirements of large-scale production lines or package printing and the like. It is commonly used for bank notes, stamps, financial documents (such as checks, bonds, stocks, business notes, bank acceptance notes, etc.), famous cigarettes, famous wines, package anti-counterfeit printing of some high-grade commodities, etc. If the anti-counterfeiting agent is used in combination with other anti-counterfeiting technologies, a better anti-counterfeiting effect can be generated. The existing printed color fluorescent product is often printed with lines such as anti-counterfeiting shading, round flowers and the like, but the color matching is single, such as various anti-counterfeiting tickets, anti-counterfeiting marks and the like; meanwhile, when the color-changing ink is used for printing images or patterns, the color is usually presented in a pseudo-color mode, and the expressive ability of the patterns is limited.

As shown in fig. 1, an embodiment of the present application provides a method for manufacturing a true color fluorescent product, including the following steps:
s1: providing an image to be printed, converting the image to be printed into an additive color mode to form a first prefabricated image, wherein the additive color mode is an RGB mode, and any color which can be seen by naked eyes in the natural world can be formed by mixing and superposing three colors, so that the image to be printed is also called an additive color mode, and particularly, the image to be printed can be subjected to mode conversion by software such as photoshop on a computer;
s2: processing the first prefabricated drawing to form a second prefabricated image in the form of a color negative image, specifically, inverting the color hue of the first prefabricated image to form the second prefabricated image, wherein the second prefabricated image is provided with an R channel, a G channel and a B channel, the R channel is internally provided with K1 image information of red color of the second prefabricated image, the G channel is internally provided with K2 image information of green color of the second prefabricated image, the B channel is internally provided with K3 image information of blue color of the second prefabricated image, and the color hue of the image is inverted to form the second prefabricated image in the form of the color negative image;
s3: and (3) making the image information of the R channel to form a first printing plate, making the image information of the G channel to form a second printing plate, making the image information of the B channel to form a third printing plate, and transferring the third printing plate, the second printing plate and the third printing plate to a printing stock to form a true color fluorescent product.
According to the manufacturing method of the true color fluorescent product, the image to be printed is firstly converted into the additive color mode, so that the first prefabricated image can be separated into three primary colors of red, blue and green, then the first prefabricated image is reversely phase-formed into a second prefabricated image, the second prefabricated image is separated into an R channel, a G channel and a B channel, the R channel is internally provided with the red K1 image information of the second prefabricated image, the G channel is internally provided with the green K2 image information of the second prefabricated image, the B channel is internally provided with the blue K3 image information of the second prefabricated image, and the first printing plate, the second printing plate and the third printing plate are respectively manufactured and formed, and can be transferred onto a printing stock through the first printing plate, the second printing plate and the third printing plate, so that the true color fluorescent product can be formed. The colorless fluorescence is excited luminescence, and based on the color light additive method, the colored image to be printed is reproduced through red, green and blue light according to the image tone and color mixture. The true color fluorescent product presents bright and bright color images with distinct tone under ultraviolet light, and the expressive force and ornamental value of the anti-counterfeiting characteristic are enhanced. The anti-counterfeiting printed matter generated by the method is based on the principles of different common color printing, namely the color light additive method principle is used, and the color image halftone process is combined, so that the fluorescent image has a color effect with continuous tone change, the anti-counterfeiting strength is further improved, the processing difficulty is higher, the anti-counterfeiting strength is more difficult to forge, and the anti-counterfeiting strength is further improved and meanwhile the anti-counterfeiting printed matter has concealment. The fluorescent display product produced by the method presents continuous tone-changing color-rich changing images under the irradiation of fluorescent lamps, the images are more vivid and have strong ornamental value, and the expressive ability is further enhanced.
In one embodiment, the making of the K1 image information to form a first plate, the making of the K2 image information to form a second plate, and the making of the K3 image information to form a third plate are specifically: the method includes performing halftone processing on K1 image information to form an H1 halftone image, performing halftone processing on K2 image information to form an H2 halftone image, and performing halftone processing on K3 image information to form an H3 halftone image. Halftoning refers to a technique of quantizing a continuous tone image (such as a gray-scale image and a color image) into a binary image or a color image of only a few colors with a small number of colors, and the quantized image has a visual effect similar to that of the original image at a distance. By the halftone processing, it is made possible to make K1 image information, K2 image information, and K3 image information into binary images, i.e., an H1 halftone image, an H2 halftone image, and an H3 halftone image, respectively, which are supported by the printing or jet printing apparatus.
In one embodiment, the halftone processing includes amplitude modulation screening and frequency modulation screening. In the digital screening technology, the amplitude modulation screening is to divide the image by invisible grids with ordered rows and columns, and each grid generates the screen dots with different areas according to a certain angle and the screen line number. In generating black/white of a recording dot, the degree of freedom in setting at each position is relatively low, because it is always limited by the screen angle, the dot shape, and the number of screen lines. Amplitude modulation screening techniques, also known as dot aggregation dot techniques, result in recorded dots in an aggregated state. We will generally refer to the dots grouped together as conventional dots whose growth is controlled by the gray level of the image information. Fm screening technology (dot discrete state dot technology) fm screening may also be referred to as dot discrete state dot technology in a sense that results in discrete distributed recorded dots. The screening calculation is not limited by the grid any more, the image is directly formed by the scattered unordered recording dot matrix pixel groups, and the freedom degree of setting at each recordable position is higher than that of amplitude modulation screening, so that the frequency modulation screening image has higher information capacity. Fm screening, also known as stochastic screening, is used mathematically to describe the process of analyzing and predicting the movement of particles in a viscous liquid, while printing is used to describe the method of precisely placing dots to create randomness and feel of tone scale. In practice, the dot positions are based on the randomness of the calculations. The spatial distribution of the dots is distributed by an algorithm, and dots are distributed according to the statistical estimation value of the tone and the details of the adjacent part of the image, so that obvious accumulation or unwanted micro-dot accumulation does not occur.
In one embodiment, the formation of the true color fluorescent article by transfer of the first plate, the second plate, and the third plate to the substrate is specifically: the method comprises the steps of applying colorless fluorescent red ink on a first printing plate, applying colorless fluorescent green ink on a second printing plate, applying colorless fluorescent blue ink on a third printing plate, and respectively transferring the first printing plate, the second printing plate and the third printing plate onto a printing stock. By arranging at least three printing plates respectively, applying colorless fluorescent red ink on the first printing plate, applying colorless fluorescent green ink on the second printing plate and applying colorless fluorescent blue ink on the third printing plate, various colors can be formulated through the three printing plates, and the original colors of the pattern to be printed are reduced.
In one embodiment, the first printing plate, the second printing plate and the third printing plate are also provided with a color band and/or a measurement and control bar for controlling white balance.
In one embodiment, the printing stock is non-fluorescent paper, in particular non-fluorescent security paper or non-fluorescent security paper. As the existing paper has fluorescence, if the paper with fluorescence is used as a printing material, the display effect of the multicolor fluorescent product can be influenced, and the paper without fluorescence or without fluorescence can be used as the printing material, so that the colorless fluorescent product has more remarkable color development effect.
In one embodiment, the colorless fluorescent red ink is a colorless fluorescent orthored ink, the colorless fluorescent green ink is a colorless fluorescent orthogreen ink, and the colorless fluorescent blue ink is a colorless fluorescent orthoblue ink. In order to better reproduce the color and tone of the reduced-color pattern to be printed, the printing ink with pure colors such as colorless fluorescent normal red, colorless fluorescent normal green, colorless fluorescent normal blue, colorless fluorescent normal yellow and the like is preferably adopted.

The printing plate corresponding to the primary color is adjusted to the last color group printing. The printing color sequence can be adaptively adjusted by analyzing the primary color of the manuscript; for example, a document with red as the primary color adopts printing with red as the last color set.
In one embodiment, the hue of the pattern to be printed is analyzed, the image information K4 of one of the intermediate leuco fluorescent inks is produced to form a fourth printing plate, and the corresponding intermediate leuco fluorescent ink is transferred onto the substrate by means of the fourth printing plate. For example, the red light and the green light can form yellow light, in order to enhance the yellow expression of the true color colorless fluorescent image, a gray image K4 can be generated by all or part of the contents containing red and green simultaneously, the corresponding halftone image H4 is formed by halftone processing, a fourth printing plate is manufactured, colorless fluorescent yellow ink is correspondingly applied to the fourth printing plate, and then the image information is transferred onto a printing object through the first printing plate, the second printing plate, the third printing plate and the fourth printing plate in sequence. Similarly, red light and blue light can form magenta, green light and blue light can form cyan, printing files and printing plates can be manufactured in the same manner, colorless fluorescent magenta ink and colorless fluorescent cyan ink are respectively and correspondingly applied, and the effect of colorless fluorescent true color printing is enhanced.
In one embodiment, the intermediate colorless fluorescent ink includes at least two primary colors. For example, red light and green light may form yellow light, red light and blue light may form magenta light, green light and blue light may form cyan light, red light, green light and blue light may form white light, to enhance the expression of reproducing the white color of a true color colorless fluorescent image, all or part of the contents simultaneously containing red, green and blue may be generated into one gray image K4, and subjected to halftone processing to form a corresponding halftone image H4, and a fourth printing plate is manufactured, to which colorless fluorescent white ink is applied correspondingly, to enhance the effect of colorless fluorescent white printing.

The true color fluorescent product manufactured by the method realizes a continuous true color image with bright fluorescence in a printing mode by means of colorless fluorescent ink, the image is colorless under natural light, conventional scanning and color separation equipment cannot recognize the image, and the anti-counterfeiting characteristic of the image can be checked only under a specific light source without reproduction, so that the anti-counterfeiting difficulty is greatly increased; meanwhile, the color image with bright brightness and distinct tone is presented under ultraviolet light, so that the expressive force and the ornamental value of the anti-counterfeiting characteristic are enhanced.
In one embodiment, the pattern is made by printing with a plurality of colorless fluorescent primary colors.
In one embodiment, the substrate is non-fluorescent paper, in particular non-fluorescent security paper or non-fluorescent security paper. As the existing paper has fluorescence, if the paper with fluorescence is used as a printing stock, the display effect of the multicolor fluorescence product can be affected, and the non-fluorescence security paper or the non-fluorescence anti-counterfeiting paper has no fluorescence, so that the paper can be used as the printing stock and the multicolor fluorescence product has more obvious color development effect.
