Description

Technical Field

[0001] This invention belongs to the field of cigarette tipping paper technology, specifically, it relates to a processing technology for gradient colored cigarette tipping paper. Background Technology

[0002] Currently, the most common colored cigarette tipping paper on the market is made by directly printing a colored layer onto ordinary tipping base paper, and then adding a protective layer on top of the colored layer. Due to the simple processing technology, this type of existing colored cigarette tipping paper has only one color and is extremely easy to counterfeit.

[0003] With the continuous introduction of high-end cigarettes in China, the aforementioned common colored cigarette tipping papers, due to their monotonous colors, make it difficult to reflect the inherent value of high-end cigarettes. In addition, they are easily counterfeited, and therefore can no longer meet the requirements of manufacturers and consumers.

[0004] Therefore, there is an urgent need for a new, gradient, and difficult-to-counter-counter color cigarette tipping paper printing process. Summary of the Invention

[0005] In view of this, the technical problem to be solved by the present invention is to provide a process for processing gradient colored cigarette tipping paper, so as to avoid the troubles of the previous cigarette tipping paper having a single color, insufficient visual appeal, and poor anti-counterfeiting properties.

[0006] To address the aforementioned technical problems, this invention discloses a processing technology for gradient-colored cigarette tipping paper, comprising:

[0007] Step a. Provide cigarette tipping paper and a gradient printing plate set, the gradient printing plate set including at least a first printing plate, a second printing plate, a third printing plate, and a fourth printing plate, wherein the first printing plate and the third printing plate each have spaced first color cells, the second printing plate and the fourth printing plate each have spaced second color cells, the first color cells and the second color cells are alternated; and the dot percentage from the first printing plate to the fourth printing plate is linearly gradient.

[0008] Step b. Feed the cigarette tipping paper into the printing press at a speed of 150-250 m / min and print the first color layer ink using the first printing plate;

[0009] Step c. Continue feeding the second printing plate at the current machine speed to print the second color layer ink;

[0010] Step d. Continue feeding the third printing plate at the current machine speed to print the third layer of ink;

[0011] Step e. Continue feeding the fourth printing plate at the current machine speed to print the fourth layer of ink;

[0012] Step f. Continue drying at a machine speed of 150-250 m / min and a temperature of 45-100℃;

[0013] Step g. Split and import into the database.

[0014] According to one embodiment of the present invention, the first color layer ink and the third color layer ink are printed with the same first color ink, the second color layer ink and the fourth color layer ink are printed with the same second color ink, and the first color ink and the second color ink are different colors.

[0015] According to one embodiment of the present invention, the first color ink and the second color ink are selected from one of red, orange, yellow, green, blue, purple, and black, or other color inks mixed in any proportion.

[0016] According to one embodiment of the present invention, the screen rulings of the first to fourth printing plates range from 30 to 90, from light to dark.

[0017] According to one embodiment of the present invention, the cigarette tipping paper base paper is selected from one of the following: ordinary type, silver-white transfer type, transparent type, high-gloss type, laser type, and direct-coating type tipping paper.

[0018] According to one embodiment of the present invention, the first to fourth printing plates are screened in both the longitudinal and transverse directions on each ink cell, so that there are different color variations in both the longitudinal and transverse directions.

[0019] According to one embodiment of the present invention, the ink quantity of the first to fourth color layer inks is 0.1-2.0 g / m2 per layer.

[0020] Compared with the prior art, the present invention can achieve the following technical effects:

[0021] By using four sets of gradient printing plates to print inks onto cigarette tipping paper, multi-color gradient tipping paper is formed by overlapping each other. This allows for the production of finished cigarettes containing tipping paper of different colors without changing the cigarette tipping paper, increasing the diversity of cigarette appearance colors and enhancing anti-counterfeiting features.

[0022] Of course, any product implementing this invention does not necessarily need to achieve all of the technical effects described above at the same time. Attached Figure Description

In the drawings:

[0024] Figure 1 This is a schematic diagram of a gradient printing plate assembly according to an embodiment of the present invention. Detailed Implementation

[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the process of how the present invention uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the gradient printing plate group according to an embodiment of the present invention, which consists of the first printing plate, the second printing plate, the third printing plate, and the fourth printing plate from top to bottom.

[0027] This invention discloses a processing technology for gradient-colored cigarette tipping paper, including:

[0028] Step a. Provide cigarette tipping paper and a gradient printing plate set, the gradient printing plate set including at least a first printing plate, a second printing plate, a third printing plate, and a fourth printing plate, wherein the first printing plate and the third printing plate each have spaced first color cells, the second printing plate and the fourth printing plate each have spaced second color cells, the first color cells and the second color cells are alternated; and the dot percentage from the first printing plate to the fourth printing plate is linearly gradient.

[0029] Step b. Feed the cigarette tipping paper into the printing press at a speed of 150-250 m / min and print the first color layer ink using the first printing plate;

[0030] Step c. Continue feeding the second printing plate at the current machine speed to print the second color layer ink;

[0031] Step d. Continue feeding the third printing plate at the current machine speed to print the third layer of ink;

[0032] Step e. Continue feeding the fourth printing plate at the current machine speed to print the fourth layer of ink;

[0033] Step f. Continue drying at a machine speed of 150-250 m / min and a temperature of 45-100℃;

[0034] Step g. Split and import into the database.

[0035] The cigarette tipping paper is selected from one of the following types: ordinary, silver-white transfer, transparent, high-gloss, laser-etched, and direct-coating tipping paper. It has wide applications and strong applicability. This invention selects a gradient printing plate group for ink printing. Specifically, the gradient printing plate group is as follows: Figure 1 As shown, the printing plate includes at least a first printing plate, a second printing plate, a third printing plate, and a fourth printing plate. These plates are stacked sequentially to print multi-color gradient tipping paper onto the base paper. The first and third printing plates each have spaced first-color cells, while the second and fourth printing plates each have spaced second-color cells. These two sets of cells are staggered, and different colors are achieved by printing different inks. The spacing between the cells facilitates different colors appearing at different levels, increasing the variety of colors on the cigarette's appearance.

[0036] Furthermore, the dot count of the first to fourth printing plates changes linearly, meaning the dot count of the printing plates is designed to gradually decrease or increase from one end to the other, creating a gradual transition. The printed inks also exhibit corresponding shades and tones, resulting in greater diversity. Additionally, multiple color variations can be achieved on a single roll of tipping paper without altering existing printing, slitting, and rolling processes.

[0037] Preferably, the first and third color layers are printed with the same first color ink, appearing on the first color printing grid; the second and fourth color layers are printed with the same second color ink, appearing on the second color printing grid, with the grids interlaced, and the first and second color inks being different colors. This creates two different color combinations on the left and right sides. In other embodiments, a fifth and sixth printing plate can also be used, similarly allowing for a third color combination, resulting in greater variety.

[0038] Furthermore, the first and second color inks are selected from one of red, orange, yellow, green, blue, purple, and black, or other color inks mixed in any proportion. Specifications for color patterns on the surface of cigarette tipping paper are provided, with wide applications.

[0039] The first to fourth printing plates of this invention have a screen ruling of 30-90 lines from light to dark, which facilitates control over color overlay accuracy.

[0040] The first to fourth printing plates involved halftone printing on each ink cell, both vertically and horizontally, resulting in different color variations in both directions. Simultaneously, the left and right sides of a single printing plate were engraved separately, ensuring that each plate's printing only applied a gradient to one side of the printing paper. Then, through the combination of multiple printing plates, the different colors on the left and right sides of each ink cell were created, along with transitions from dark to light or from one color to another.

[0041] The ink quantity for each of the first to fourth color layers is 0.1-2.0 g / m², which is clear and distinct.

[0042] In summary, this invention uses four sets of gradient printing plates to print inks onto cigarette tipping paper, which are then overlaid to form multi-color gradient tipping paper. This allows for the production of finished cigarettes containing tipping paper of different colors without changing the cigarette tipping paper, thereby increasing the diversity of cigarette appearance colors and enhancing anti-counterfeiting features.

[0043] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
