Analysis of the advantages of pre-printing on roll-to-roll color box

2 From Lonely Strife to Specialized Collaboration

Sichuan Color Printing Co., Ltd. has chosen the roll-to-roll color box and color box printing from the very beginning, and has always been looking for packaging plants with automatic corrugated production lines to cooperate in the production of color boxes. Has invested more than 1 million US dollars to buy 6-color satellite flexo printing machine in Italy (imprinting roller with a thermostat device). From equipment to factory installation and commissioning, flexo platemaking companies, ink-and-water companies, paper mills, and corrugated paper box plants all actively participated in the process, and they are eager to produce the color box products needed by the market. However, in reality, because the entire process was not planned and planned, each team struggled alone in the trial of color box and the results were repeatedly defeated.

1) The mistake of selecting a sample draft. The plate was printed in a real-sample carton. The two parties also did not communicate technically, not only for the flexographic plate-making company, but also for the flexo printing machine can not print the same color as the sample box, resulting in adjustment of the plate-making process, re-making plate, increasing the plate-making cost. Compared with offset printing, offset printing always occurs. After constant adjustments and improvements, disconnected networks and other issues such as hue and registration are gradually approaching that of the original model, and then the corrugation line test is being prepared.

2) The color rolled over the corrugated line, and the colorful noodle could not bear toleration. After the flexo printing, the color surface is close to the real color box. It should be said that great progress has been made. However, the color roll is run along the corrugating mechanism in the liner of the automatic corrugation line. The color surface passes through the preheated guide roll, and the color surface is directly in contact with the non-rotating heat roll and the sized corrugated paper. Drying, ironing section, at this time, in the adhesive pressure of the belt, the color surface directly at a temperature of about 200 °C does not move on the hot plate, the color screen has been beyond recognition, the beautiful screen was snow-like, color surface was pulled Spotted, and some were pulled into a ditch, unsightly, and all became waste.
3) Corrugated line cross cutter defects. The traditional automatic corrugation line, the cutting Knife can not be at the given cross-cut line between the screen under the knife, but cut according to the length of the size of the cut box pieces are all scrap.

In the face of repeated failures, the material factory, printing factory, corrugated box factory, and every family have been disheartened, and the plate-making fee, ink fee, and reel paper are all borne by the Flexo factory and can no longer afford hundreds of thousands of yuan. The experimental expenses. The roll-to-roll color box printing almost came to an end.

The process of color box production must be followed by the traditional way of self-supporting, large and full, or small and full road. Although convenient, it actually has a large investment, low utilization rate, low utilization rate of equipment, low input-output and labor productivity, and it is at a disadvantage in market competition. As a volume-to-volume color box production, each battle is impossible.

Another method is the collaboration of process systems and the advantages of their own equipment, technologies, and services in each process, and the complete process of volume-to-volume color box production. This combination of resources using off-the-shelf equipment, manpower, technology, and markets can be a collaboration of product process technology chains, or a combination of capital operations on this basis. The center is the integration of resource advantages, rapid, efficient, and collaborative volumes. Production of volume lottery boxes to meet and develop market demand for commercial color boxes.

From June 11 to June 15, 2002, at the second session of the first session of the flexographic professional committee of the China Printing Association and the fourth session of the China International Symposium on Soft Gravure Printing, the author proposed that the volume-to-print color box is a System engineering, relying solely on the voluntary efforts of any manufacturer in the volume-to-volume color box production process, can not achieve volume-to-volume color box production. Only the joint efforts of plate making, ink painting, paper, printing, and corrugated cardboard boxes will have a way out. Participated in the seminar of Dalian Fulao Flexographic Plate Co., Ltd., Dongguan Yingjie Laser Digital Plate Making Co., Ltd., Tianjin Dongyang, Bailin Weili, Beijing Iris Ink Co., Ltd., Shanghai Taige Packaging (Shanghai) Co., Ltd., Qingdao Shaoshan Shuangtai Middle School Carton Factory Such as corrugated packaging companies, material suppliers Jiuheng Printing and Packaging Co., Ltd., Shanghai Okure Printing Machinery Co., Ltd., and even mid-end customers of Budweiser (Wuhan) International Brewery Co., Ltd. and other participants, reached volume-to-volume color box production. Systematic consensus. On this basis, Yin Jinhua, a teacher from the Shanghai Printing Academy, advocated that in the volume-to-volume color box printing system project, only the flexo printing process could be used throughout the entire process to complete the requirements of the next process collaboration plant to the upper process collaboration plant. Collaboration in the production of color boxes. Based on this consensus, Sichuan Color Printing Co., Ltd. has successively worked with flexographic printing companies, ink companies, paper companies, and corrugated cardboard packaging companies to develop a cooperation agreement for the production of roll-to-roll color boxes with the printing process as the main line. Clear responsibilities, obligations, and goals for the entire process of collaboration and research. Respectively fulfill their responsibilities, overcome difficulties, work together, until the customer satisfaction, until the closure. Taking “Sample Sample” as the end of the collaborative experiment, taking inventory of their respective inputs, assuming the capital, technology, and labor costs invested in each process section during the experimental period; and using “closed samples” as the starting point for collaborative production, when the production plan is completed. ,Pay the fee for the plate-making company, the remaining ink and ink, new ink, varnish, paper roll and other expenses into the normal procurement and payment procedures of the supply chain; Flexographic printing, rewinding, packaging, and shipping of the color paper; Finalize the production of color boxes and deliver color box products. From November 2002 to March 2003, nearly 2 million color boxes were supplied to the five major varieties of Tsingtao Beer and bottled varieties of Budweiser beer through division and collaboration under the flexo printing process. Volume-to-volume color box production has entered large-scale operations.
