Problem 1: Prepress proofreading is difficult and walking on thin ice. Due to factors such as customer samples, production habits, software versions, etc., it has always been a high-risk link in printing. A slight error before printing can lead to huge printing losses.
Solution: Implement automatic and remote cloud proofreading with the help of processes and professional tools, seamless connection between manuscript-production-proofreading-output, process display, alarm prompts, tracing and recording. And connect the machine vision inspection equipment with the printing machine to complete the accurate proofreading and 100% quality link between the printing machine and the printing machine, and create conditions for the realization of the black light factory for intelligent printing.
Problem 2: The end-to-end color transfer in the industry chain is not standardized. Today, with the popularization of multi-color lines of printing machines, metal printing colors still cause the biggest problem and the biggest cost loss in factory quality inspection and management.
Solution: The color process refers to: designer-brand-manufacturer-ink distributor-printer-can maker, the color transfer includes:
- The visual difference of the physical sample under different light source conditions
- The Pantone color number has the difference between the old and the new version
- The color There are different standard systems for degree values and tolerances.
Effective transmission is the condition for the final reproduction of color, and deviations in any link lead to deviations in results. Color transfer is very developed and mature in the paper printing industry, while metal printing companies attach less importance to acceptance and popularity. Compared with international iron printing and other printing industries, it is slightly closed and lagging behind. On the other hand, how do metal packaging printing companies regulate color transfer, measurement, and how? International and domestic industry printing quality and standards, what are the new requirements for quality standards? And what instruments and equipment are currently applicable to the metal packaging industry, and how to choose them correctly? Instrument selection and measurement of background white, metallic color, matt artistic special effect color, and laser color, screen correction color involved in color management, proofing data set scanner, PS version data measurement, etc., international and domestic suppliers have shown us the latest Results and solutions, metal printing color testing is no longer difficult, and the transmission of color specifications in the industrial chain has been proven not only possible, but also necessary and feasible.
Question 3: The general standardization foundation of iron printing enterprises is weak, which makes the upgrading of iron printing process technology and color management, and the application of digital proofing existing obstacles.
Solution: The outstanding problem is that the same manuscripts, equipment, and personnel cannot keep up with the samples and colors. Digital proofing is high, cannot guide production, and cannot replace contract proofing. Partially replaces the goal of contract proofing. ——PS version output, printing digital proofing output, printing equipment, printing material control, personnel operation, observation conditions and other factors are unstable and non-standard, lack of data and standard control, and management based on experience alone will eventually lead to the instability of the finished product. There are many inconveniences and technical limitations in the working hours of color complementing, sheet picking, brand communication, and the quality requirements of international orders. The printing process control and testing standards need to be strengthened urgently. This workshop invited COFCO Packaging, O.R.G., Shanghai Publishing and Printing College and other special topics to introduce the latest domestic and foreign iron printing standards and the handling of common problems. It was a rare learning and exchange experience.
Question 4: On the one hand, the speed of the printing press is getting faster and faster, and the small orders are getting more and more frequent. Relying on the captain to guard the door, the risk is extremely high.
Solution: This training will sort out the whole process from the perspective of printing reproduction and color management, divide the responsibilities, build the original manuscript, PS version, digital sample, and printed product process and testing and evaluation plan that conform to the actual situation of the company, and formulate a continuous, stable and consistent program. Print quality workmanship and standards. Experts from the college are invited to explain ISO international iron printing standards, GMI customer certification standards, metal printing industry quality and process control standards, inspection and testing standards, etc., and will also introduce the principles of standard drafting, matters needing attention, and problems in implementation to provide enterprise product standards. Reference and reference.
Question 5: The traditional “four-color plus spot color” process of metal printing is the same. In the current vision, attention and experience economy, it is difficult to meet the visual and feel experience requirements of brand owners and young consumers who pursue fashion and entertainment interaction. In the face of the diversified designs and exquisite manufacturing of other packaging materials and processes, it is very difficult to maintain the market share of metal packaging.
Solution: Collaborative innovation in the industrial chain, using the stones of other mountains. Carry out value-added printing, experiential interactive printing, build process design auxiliary tools such as “design molding, simulation proofing, seamless conversion and deformation printing”, master high-definition printing technology and practice (350 lines and FM network), wide color gamut full professional Color printing and technology (4-7 colors), anti-counterfeiting personalized printing and practice, art glazing, cross-border mixed printing and use case sharing of special synergistic art inks, expand the vision of process technology, and diversify and diversify iron printing products. Advancedization, technology and humanistic experience, and high-quality transformation and upgrading have been implemented.
