Abstract
Description
Technical Field
[0001] The invention relates to the field of printing and packaging machinery, and in particular to a modular multifunctional digital value-added processing system and a processing method. Background Art
[0002] In recent years, the market demand for short-term and fast prints has continued to grow, and the application rate of digital enhancement in the field of on-demand printing has also increased accordingly. However, the promotion of the digital enhancement market still faces some challenges: 1. Currently, multiple enhanced prints need to be prepared and run repeatedly, resulting in a waste of manpower, materials and time. In the face of the need for digital enhancement with different effects, it is usually necessary to use independent single-process equipment to process the prints multiple times.
[0003] 2. Digital enhancement processing equipment occupies a large area. In order to avoid the substrate from contacting or scratching the nozzle during the transfer process, most digital enhancements currently use the nozzle to spray ink on the substrate that is transported in a straight line, which leads to the problem of occupying a large area.
[0004] 3. Digital printheads cannot use matte and tactile coatings containing larger particles such as matte powder. Currently, matte effects are usually achieved by offline matte film or software simulation, but the efficiency is low and the effect is not good.
[0005] 4. How to perform digital value-added online and maintain registration accuracy after the printed sheets are laminated is also a problem. After lamination, when the printed sheets are connected end to end for alignment spraying, the existing structure cannot ensure the consistency of the angle between the laminated film edge and the printed sheet side edge, which is prone to skew.
[0006] At present, whether using pioneer brands such as Scodix and MGI, or emerging domestic digital enhancement equipment, in order to achieve high-contrast visual effects, it is usually necessary to first coat the matte / soft touch surface through coating equipment, and then perform digital enhancement processing. This repeated processing and operation process leads to low efficiency and high cost, limiting the market popularity and cost of multi-effect products.
[0007] The laminating equipment on the market usually uses a roll film that is slightly narrower than paper to laminate the printed sheets, and then breaks the sheets after forming the roll material to restore the printed sheets to a single sheet state. This batch and offline operation is because the laminating equipment cannot ensure that the printed sheets can be consistently pushed to the lamination point with the film after being positioned by the front and side gauges.
[0008] At the 2016 Drupa World Printing Show, Autobond tried to add a conveyor belt and a ball-type side trimming device, as well as an electric eye and a digital enhanced point spraying device to the pre-coated film laminating equipment. However, the equipment was too long and the conveyor belt had insufficient transmission accuracy, so it failed to gain market recognition.
[0009] In 2017, Duplo launched a desktop device that can perform lamination, partial cold stamping and glazing, but it can only operate in a low-speed single process and cannot meet the needs of on-demand processing.
[0010] Although the industry has tried to perform digital precision registration spraying on laminated printed sheets, the sides and angles of the printed sheets cannot be kept consistent after coating and before digital spraying due to inconsistent pressing time of the left and right rubber wheels.
[0011] The digital value-added platform of the prior art utilizes laminating equipment to perform matte lamination or matte treatment on thick paper sheets. When the matte-laminated or matte-treated thick paper substrate needs to be processed to generate transparent or digital glazing or digital cold stamping, the processed thick paper substrate needs to be taken out and re-fed and corrected. Therefore, if the prior art needs to perform multiple processes on the same substrate, the efficiency is relatively low, and the position of the substrate is offset during the repeated feeding process, resulting in a low output yield rate of the substrate.
[0012] Even if the existing digital value-added platform uses laminating equipment to first perform matte laminating / matte treatment on thick paper sheets and then form digital C2 glazing or transparency on this platform, if other processing is desired, it is necessary to repeatedly enter the platform for processing.
[0013] The states of the laminating process in the prior art include: State A: digital enhancement, which requires visual positioning + software precise positioning; State B: the ideal traditional laminated printed sheets are not skewed and can be continuously digitally enhanced; State C: the actual traditional laminated printed sheets are not aligned, the printed sheets are skewed, and digital enhancement is impossible.
[0014] In summary, how to shorten the space required for the digital enhancement process, combine matte processing with digital enhancement, and overcome the problem of paper skew and inconsistent angles entering the composite point are challenges that the industry urgently needs to solve. At the same time, the industry is also looking for a processing system that is efficient, high-precision, does not occupy space, reduces energy consumption, and can achieve high-contrast visual and tactile effects.
