Digital printing machine for corrugated paper face paper

Abstract

The invention relates to a digital printing machine for corrugated paper face paper, and belongs to the technical field of digital printing or green printing. The digital printing machine comprises afeeding mechanism used for conveying flexible face paper to be printed, a dust removing mechanism used for removing dust on both sides of the flexible face paper and making the surface of the flexibleface paper rough, a deviation rectifying mechanism used for adjusting the position of the flexible face paper in the width direction, a humidifying mechanism, a plurality of sets of printing mechanisms and a drying mechanism, wherein the humidifying mechanism comprises a water vapor generator, the water vapor generator is arranged below the flexible face paper and can generate water vapor and wetthe flexible face paper to make the humidity of the flexible paper face uniform and reach the standard; each set of printing mechanisms corresponds to printing a single color and dries the surface ofa printed ink; and the drying mechanism is used for drying the flexible face paper. Through the receipt of the face paper humidification, it is ensured that the humidity of the face paper in the width direction is more balanced before printing, the color mixing uniformity of the ink and the bottom color of surface paper is ensured, and the printing quality is improved.

Description

technical field [0001] The invention relates to a digital printing machine for corrugated paper, which belongs to the technical field of digital printing or the technical field of green printing. Background technique [0002] Digital printing is a new type of printing technology that uses the pre-press system to directly transmit graphic information to the digital printing machine through the network; the digital printing system is mainly composed of the pre-press system and the digital printing machine. Some systems are also equipped with binding and cutting equipment. Working principle: The operator outputs the digital information of the original manuscript or digital media or the network digital files received from the network system to the computer, and then creates, modifies and arranges the digital information on the computer to become the digital information satisfactory to the customer. After RIP processing, it becomes the corresponding digital information. The mono...

Problems solved by technology

[0003] Corrugated cardboard has a large amount of use in modern life or external packaging, so it has a large printing volume, because the existing corrugated paper rolls are often prone to moisture on both sides in the width direction during long-term storage , and the middle part is relatively dry, so that when printing corrugated paper, the degree of ink infiltration is often different due to the different humidity of the paper in the width direction, and, because the paper often has a background color, the color of the ink is different from the background color of the paper. The degree of color mixing is not the same, which affects the printing quality. Therefore, solving the problem of uniform color mixing when printing corrugated board surface paper has become an urgent problem to be solved in the prior art.
