Problems solved by technology

This way of using specific standards of corrugated cardboard and specific layers has caused great restrictions on flexographic printing, and because it uses post-printing technology, it greatly limits the weight of paper in flexographic printing and limits the corrugated. Direction, can only be printed in the vertical direction, can not be printed in the parallel direction, the printing speed is slow, the printing process is to print on the paper plate, the physical strength is low, and it cannot be coated, so that the accuracy of the corrugated cardboard printed in this way, There are still some unsatisfactory aspects in terms of color brilliance and glossiness of printed matter

Embodiment 1

[0028] (1) Plate making: According to the designed text pattern, use the high-end flexible resin plate DRC of DuPont Company in the United States to make a seamless sleeve flexible printing plate through laser engraving. The thickness of the printing plate is 1.7mm, and the hardness is 80 Shore hardness;

[0029] (2) Ink preparation: prepare water-based ink with a viscosity of 40 seconds, a coloring rate of 100%, a fineness of 26, and a pH value of 9;

[0030] (3) Varnish preparation: prepare a water-based varnish with a viscosity of 40 seconds and a solid content of 50% that can withstand high temperatures of 160-200°C;

[0031] (4) Roll printing: The ink in the ink tank is transferred to the honeycomb ceramic anilox roller through the ink roller, and then the anilox roller transfers the ink evenly to the flexographic plate. The graphics and text on the plate are transferred to 100g paper at a speed of 300-500 m / min; and the water-based varnish is covered on the printed matt...

Embodiment 2

[0038] (1) Plate making: According to the designed text pattern, use the high-end flexible resin plate DRC of DuPont Company in the United States to make a seamless sleeve flexible printing plate through laser engraving. The thickness of the printing plate is 3.94mm and the hardness is 60 Shore hardness;

[0039] (2) Ink preparation: prepare water-based ink with a viscosity of 30 seconds, a coloring rate of 100%, a fineness of 35, and a pH value of 8;

[0040] (3) Varnish preparation: prepare a water-based varnish with a viscosity of 30 seconds and a solid content of 50% that can withstand high temperatures of 160-200°C;

[0041] (4) Roll printing: The ink in the ink tank is transferred to the honeycomb ceramic anilox roller through the ink roller, and then the anilox roller transfers the ink evenly to the flexographic plate. The graphics and text on the plate are transferred to the 400g cardboard at a speed of 300-500 m / min; and the water-based varnish is covered on the prin...

Embodiment 3

[0049] (1) Plate making: According to the designed text pattern, use the high-end flexible resin plate DRC of DuPont Company in the United States to make a seamless sleeve flexible printing plate through laser engraving. The thickness of the printing plate is 2.9mm, and the hardness is 70 Shore hardness;

[0050] (2) Ink preparation: prepare water-based ink with a viscosity of 30 seconds, a coloring rate of 90%, a fineness of 30, and a pH value of 9;

[0051] (3) Varnish preparation: prepare a water-based varnish with a viscosity of 50 seconds and a solid content of 50% that can withstand high temperatures of 160-200°C;

[0052] (4) Roll printing: The ink in the ink tank is transferred to the honeycomb ceramic anilox roller through the ink roller, and then the anilox roller transfers the ink evenly to the flexographic plate. The graphics and text on the plate are transferred to the 200g cardboard at a speed of 300-500 m / min; and the water-based varnish is covered on the print...

Abstract

The invention discloses a method for manufacturing a wide-width color flexible preprinted corrugated carton, which comprises the steps of: plate making, ink preparing, varnish preparing, web-feed printing, cardboard flailing, cutter template manufacturing, die cutting and the like. Printed products manufactured by the method have bright color, accurate chromatograph, thick ink layers and vivid pattern restoration, can synchronously realize indexes of gloss, abrasion resistance, skid resistance and high-temperature resistance. In the method, an international environmentally-friendly honeycomb ceramic roll with water-based ink, water-based varnish and high reticles and the shortest ink transferring path are adopted, so the printing cost is saved, and the product quality and production efficiency are improved greatly.

Description

technical field [0001] The invention relates to a method for manufacturing a flexographic pre-printed corrugated carton, in particular to a method for manufacturing a wide-width color flexo pre-printed corrugated carton. Background technique [0002] Flexographic printing (also referred to as "flexo printing") is one of the reasons for the rapid development of flexo printing in foreign countries because of its unique flexibility, economy, and environmental protection. At present, 65%-70% of packaging in the United States is flexographic, and the share of flexographic packaging in Europe also accounts for 60%. In the packaging industry in the United States and Europe, flexo printing has penetrated into food, beverage, beer, dairy products, medicine, cosmetics, electronic products and other fields. [0003] According to the current situation in our country, offset printing is relatively popular, and gravure printing has also occupied a large market in the packaging industry, ...
