Description

Technical Field

[0001] The present invention relates to the technical field of digital printing, and in particular to a tactile marking printing device, method, electronic device, and readable storage medium. Background Art

[0002] Tactile recognition is the most direct way and means for this group to understand the world and facilitate their lives. In the past, dot matrix printers were usually used to print tactile marked books, but their scope of application was limited. For example, they could not print on hard materials such as metal and plastic, high-end anti-counterfeiting products such as wine and cigarette packages, or securities products such as banknotes and ID cards.

[0003] The tactile identification marks on paper banknotes at home and abroad adopt the traditional engraved gravure printing process. The deformation of the paper and the thickness of the ink accumulation constitute the tactile height of the tactile identification mark, and the wear resistance is poor. The tactile identification marks on foreign plastic-based banknotes mostly use the hot embossing process to make the plastic substrate produce plastic deformation to form the tactile height of the tactile identification mark, which has wear resistance, but the printing ink at the corresponding position is pressed and raised, which aggravates the wear and usually causes serious wear and ink loss. In addition, some patents involve related processes for printing tactile identification marks, providing a method for printing tactile marks on the surface of securities products such as banknotes through screen printing, but this method is limited by the screen process and affects its printing accuracy; another patent provides a tactile mark printing method based on the principle of digital inkjet printing, but the former requires printing the main image first and then printing the raised image; the latter can achieve the printing of raised points with a large aspect ratio, but it has requirements for the printing substrate.

[0004] Traditional printing technology generally achieves the above-mentioned high tactile features through gravure and hot embossing processes, but due to the characteristics of the substrate, printing pressure, printing plate, etc., the height of the tactile features formed is generally small and does not have the ability to print variable information. Digital inkjet printing technology is mainly used in variable information printing, and is less used in high tactile feature printing, with limited printing accuracy and certain requirements for the substrate.

[0005] The existing tactile identification logo printing has problems such as limited application scope, insufficient printing accuracy, poor wear resistance, and ink wear on printed products. Even the occasional high-tactile feature printing is based on a multi-PASS printing method with a single fixed substrate and a moving inkjet print head (multi-PASS printing is a technology that performs multiple overprints on the same screen during printing or printing), which has certain limitations in production efficiency and effect.

[0006] The embodiments of the present invention aim to solve at least one of the above technical problems.

[0021] like Figure 1 and Figure 2 As shown, the present application provides an embodiment of a tactile marking printing device 100 .

[0022] The tactile mark printing device 100 includes a tactile mark printing unit 110, and the tactile mark printing unit 110 includes a transmission device 112 and at least one group of digital printing modules 120; the digital printing module 120 includes at least one inkjet print head 122 and at least one pre-curing unit 124, and the pre-curing unit 124 is arranged on one side of the inkjet print head 122; the digital printing module 120 and the pre-curing unit 124 are arranged above the transmission device 112, and the transmission device 112 includes a conveying platform 114 and a driving roller 116, and the transmission device 112 is used to convey printed items; a code printing unit 132 is arranged at the paper feeding end of the tactile mark printing unit 110; a coating unit 134 is arranged at the paper receiving end of the tactile mark printing unit 110; wherein each inkjet print head 122 has a position overprint relationship. In the tactile mark printing device 100 provided in the present application, the inkjet print head 122 of each digital printing module 120 and the inkjet print heads 122 of different digital printing modules 120 have an absolute position overprint relationship. The printed content of each group of digital printing modules 120 has a close overprint relationship. By performing inkjet printing with different digital printing modules 120, multi-process joint printing and high tactile characteristics of printed objects can be achieved, and the applicable scope, printing accuracy and wear resistance of printed objects can also be improved.

[0023] The tactile mark printing device 100 provided in the present application is composed of at least one digital printing module 120, a pre-curing unit 124, a curing unit (drying unit 138) and other related systems. During the one-time conveying process of the substrate, high-precision multiple overprint printing of the tactile mark can be achieved to obtain the printing of the physical height required for the tactile mark. Two inkjet print heads 122 and a pre-curing unit 124 can be set in each digital printing module 120. The two inkjet print heads 122 are arranged side by side, and one pre-curing unit 124 is arranged behind the second inkjet print head 122. After the printed article is printed by the two inkjet print heads 122, the pre-curing unit 124 starts to cure the printed area of ​​the printed article. The digital printing module 120 includes two inkjet print heads 122, which can achieve splicing with high printing resolution. The two inkjet print heads 122 in the digital printing module 120 can be distributed in position (such as horizontally, vertically, etc.) according to actual needs. The inkjet print heads 122 of each digital printing module 120 and the inkjet print heads 122 of different digital printing modules 120 have an absolute position overprint relationship. The positional relationship between different inkjet print heads 122 and the print heads between different modules can achieve repeated printing at the same position on the printed product. The printed content of the tactile marking printing device 100 has a close overprint relationship (the overprint relationship includes adjacent, mutually nested, partially overlapped, completely overlapped, etc.). For example, a high tactile feature can be achieved through the complete overlap relationship of the inkjet printed content of different digital printing modules 120. All digital printing modules 120 are arranged on a transmission device 112, and the transmission device 112 includes a conveying platform 114 and a driving roller 116. The transmission device 112 is used to convey printed items.

[0024] The tactile marking printing device 100 provided in the present application has a close fitting relationship between each group of digital printing modules 120. By performing inkjet printing through different digital printing modules 120, multi-process combined printing and high tactile characteristics of printed objects can be achieved, while also improving the application range, printing accuracy and wear resistance of printed objects.

[0025] It should be noted that two inkjet print heads 122 are selected in the tactile mark printing device 100 of the present application in order to improve the printing resolution. The two inkjet print heads 122 can be spliced ​​horizontally or vertically. One inkjet print head 122 can also achieve the effect of the present application, but the resolution may be reduced. The core of the present application is to achieve superimposed printing at the same position of the printed product by arranging different printing modules, thereby achieving a certain tactile height.

[0026] In an optional implementation of the present embodiment, the conveying platform 114 of the transmission device 112 can be a paper transfer roller. When the conveying platform 114 is a paper transfer roller, the digital printing module 120 surrounds the paper transfer roller, and the inkjet print head 122 and the pre-curing unit 124 are distributed in a star shape as a whole, wherein the printed items are transmitted by the rotation of the paper transfer roller.

[0027] In another optional implementation of the present embodiment, the conveying platform 114 of the transmission device 112 can be a conveyor belt. When the conveying platform 114 is a conveyor belt, the digital printing module 120 is arranged above the conveyor belt, and the inkjet print head 122 and the pre-curing unit 124 are distributed linearly as a whole, wherein the printed objects are transported by the conveyor belt.

[0028] A drying unit 138 is disposed behind the last group of digital printing modules 120. The drying unit 138 is disposed between the last group of digital printing modules 120 and the coating unit 134. After the printed article passes through the inkjet print head 122 and the pre-curing unit 124 in the last group of digital printing modules 120, the drying unit 138 dries the printed article. A paper feeding unit 130 and a code printing unit 132 are disposed at the paper feeding end of the tactile mark printing unit 110. A coating unit 134 and a paper receiving unit 136 are disposed at the paper receiving end of the tactile mark printing unit 110. The paper feeding unit 130 is connected to the code printing unit 132, and the code printing unit 132 is located between the tactile mark printing unit 110 and the paper feeding unit 130; the paper receiving unit 136 is connected to the coating unit 134, and the coating unit 134 is located between the tactile mark printing unit 110 and the paper receiving unit 136.

[0029] In an optional implementation of this embodiment, the tactile mark printing device 100 can perform single-process or multi-process joint printing for a single sheet of paper, and the tactile mark printing device 100 can also perform single-process or multi-process joint printing for a roll of paper, and can realize multiple information printing and multiple code printing and coating printing. The tactile mark printing device 100 can be a single-process printing device for a single sheet of paper or a roll of paper, and the tactile mark printing device 100 includes a single-process printing unit, a paper feeding unit, a paper receiving unit 136, and an online detection unit. The tactile mark printing device 100 can be a single-process joint printing device for a single sheet of paper or a roll of paper, and the tactile mark printing device 100 includes a digital printing module 120, a multi-process printing unit composed of other printing processes (such as code printing, coating, etc.), a paper feeding unit, a paper receiving unit 136, and an online detection unit. The tactile mark printing device 100 can realize variable information printing and multiple printing functions (code printing, coating, etc.). The pre-curing unit 124 has a pre-curing function, specifically, it performs a pre-curing drying process immediately after each printing module is printed, and the corresponding drying power is low. The drying unit 138 has a high-power drying mode, that is, the final drying and curing of the printed product after all printing modules are printed.

[0030] like Figure 1 and Figure 2 As shown, the tactile mark printing device 100 includes a plurality of digital printing modules 120, namely P1, P2, P3...Pn (n≥1). Each digital printing module Pn includes at least one ( Figure 1 and Figure 2 The above-mentioned multiple digital printing modules 120 are distributed in a star shape along the circumference of the paper transfer cylinder (such as Figure 1 ), or distributed linearly along the paper feeding direction of the paper conveying platform (as shown in Figure 2 As shown in the figure), each digital printing module 120 is perpendicular to the corresponding tangent line of the paper transfer roller or the paper feeding direction of the paper transfer platform. In practical applications, the position and height of each digital printing module 120 relative to the paper transfer roller or the paper transfer platform are adjustable. The above-mentioned tactile marking printing device 100 and the paper feeding unit 130, the code printing unit 132, the coating unit 134, the curing unit (drying unit 138), the online detection unit, the paper collection unit 136, etc. can optionally form a single-process or multi-process printing device. The printing device is suitable for printing on a single substrate or a roller substrate. Among them, Figure 1 The direction of the arc arrow above the middle transfer roller represents the rotation direction of the transfer roller.

[0031] It should be noted that the tactile mark printing device 100 provided in the present application can print tactile marks used by the visually impaired on the surface of high-end anti-counterfeiting products such as cigarette packages and wine packages, banknotes, passports, ID cards (identification cards) and other securities products, providing convenience for the daily life of this group. At the same time, the tactile mark printing device 100 of the present application is composed of multiple digital printing modules 120, pre-drying and drying systems, etc. The tactile mark printing equipment can be a single-process digital printing equipment, and can also be a multi-process joint printing equipment composed of a relief process unit, a coating process unit, etc.

[0032] like Figure 3 As shown, a tactile marking printing method according to an embodiment of the present invention is shown.

[0033] Specifically, Figure 3 As shown, in S102, based on the printed article entering the tactile mark printing device, at least one digital printing module in the tactile mark printing device performs inkjet printing on the printed article; In S104, a pre-curing unit is used to perform a curing process on the printed objects completed by inkjet printing of each group of digital printing modules; In S106 , the printed article that has been finally printed is dried and cured by the drying unit, and the printed article that has been finally dried and cured is transferred to the coating unit.

[0034] In this embodiment, for S102, the printed article is sent to the tactile marking printing device for tactile marking and printing. The digital printing module in the tactile marking printing device performs inkjet printing on the printed article, wherein the digital printing module is composed of two inkjet print heads, which can achieve high-resolution splicing of the printed article. Multiple groups of digital printing modules are set in the tactile marking printing device. According to the printing requirements of the printed article, the multiple groups of digital printing modules jointly print the printed article, and the overprint accuracy between the multiple groups of digital printing modules is controlled to obtain the tactile height and fine printing effect required for tactile marking printing.

[0035] Afterwards, for S104, the pre-curing unit is used to cure the printed items completed by each group of digital printing modules. For example, after each group of digital printing modules completes inkjet printing, they need to be cured by the pre-curing unit. Similarly, after the previous group of digital printing modules is printed, they are cured. Then, the next group of digital printing modules prints and is cured, until all digital printing modules are processed.

[0036] Finally, for S106, the drying unit is used to dry and solidify the printed items that have been finally printed, and the printed items that have been dried and solidified are transferred to the coating unit. For example, after the last group of digital printing modules has been printed and pre-cured, the drying unit is used to dry and solidify the printed items that have been finally printed. After the drying and solidification process is completed, the printed items need to be transferred to the coating unit for coating.

[0037] The tactile mark printing method provided in the embodiment of the present application obtains the tactile height and fine printing effect required for tactile mark printing by controlling the printing of multiple groups of digital printing modules. High tactile characteristics can be achieved by completely overlapping the inkjet printing contents of different digital printing modules.

[0038] In some embodiments, the tactile mark printing method is a multi-spot color high-precision overprinting printing process method with high overprinting accuracy, which is not less than ±0.15mm. The tactile height and printing fineness required for tactile mark printing are obtained by controlling the overprinting accuracy between multiple groups of digital printing modules.
