First of all, Zhang Shizhen, from the Research Institute, said that promoting environmental protection is not only to protect the earth's ecology, but also to continue the printing industry. More importantly, it is energy saving and carbon reduction to reduce greenhouse gas emissions and the extreme climate change of the earth. Green printing also brings lower costs to the printing industry. More importantly, the printing industry is promoting green labels. If it can obtain green environmental labels in the future, it may become an important condition in foreign export business and government tendering work. And indicators, especially the Chinese government in the 12th Five-Year Plan, the printing textbook manufacturers are limited to printing companies with environmental certification, but only 100 of the current 100,000 manufacturers have obtained this environmental certification, this is the printing standard for Taiwan. Maybe there is a possibility of development. Therefore, environmentally friendly low carbon is not only beneficial to others, but also more conducive to the development of the cause. The Research and Development Center is working hard on carbon footprint certification and environmental protection and energy conservation counseling. The purpose of today's seminar is to promote understanding and environmental protection in the southern industry.
The first session was led by Chairman Chen Zhengxiong of the Research and Development Center: Looking at the development trend of printing materials from DRUPA 12.
First, in the prepress, the previous manuscript production, using computer typing to flush the output photo paper, not only the photo paper is silver salt photosensitive material, the flushing waste liquid must be processed, the film must be washed again, the line draft should also be photographed . Color photos should be photographed with silver salt color negative film, then use the scanner to separate the color, then manually group the page small version, one time sensitive and rinse, and some need to copy the negative and then turn the sun, repeat Third, four silver salt film and rinse to complete the large version of the film. Since there are DTP digitized content, digital images have a lot of files, texts and graphic files, each with different characters and vector graphics files. The earliest output of the page negatives, the use of artificial collage, saving a lot of tasks and contaminated photosensitive silver salt material. Then the print output machine makes a full-page 8-page negative output, which saves on the process and materials. Today, CTP shortens the process, avoiding negative or full-page prints, and only uses a low-pollution CTP plate output, not only fast but also more refined. Scanners and high-resolution digital cameras play an important environmental role in the printing of sophisticated image capture. CTP has replaced CTF. Recently, due to the high price of silver in the film material and the reduction in the number of people using it, the cost of the original CTF film plus the PS plate is lower than that of the CTP plate. The price of the film is lower than that of the CTP version. The material is much more expensive. The disappearance of CTF is replaced by CTP. It is not just the demand for environmental protection, but it has to be changed because the cost is rising rapidly. If CTP is only process and material saving, we should also consider the use of CIP 4, so that the printing machine and post-processing equipment can quickly adjust the size and thickness to the processing order under the CIP 4 data control. The opening degree can be calculated according to the pre-press 1bit Tiff output CTP file to calculate the cumulative percentage of prints, and then convert the ink key opening degree, not only fast, not too much school bus material, work quality is faster, more accurate and less waste. The automatic JDF file in the MIS production asset management system can leave data usage, cost and benefit analysis. The CTP flat printing plate is produced with no chemical solution, such as Azura Agfa, which is used to remove the nano-powder from the sintered plate. Use water development, less chemicals, such as 15% to 25% of drug development, to reduce tube end treatment. Flexographic CDI is directly plated, free of film, and of better quality. Hot-burning type without chemical hot gasification plate making. The screen version of CTS is directly imaged by Luscher and other manufacturers. Use the CTP version of the four-color scan and the original PDF file to create a text, print and color simulation of the Fujifilm ECO NEX inspection system to prevent the printing of misprinted parts.
The offset printing machine uses UV LED lamps combined with high-sensitivity ink curing, which can reduce power consumption by 75~80% and reduce the occurrence of O3 ozone harmful substances. Ryobi's R-928P uses UV LED lamps, which are printed on the front side to make a solidification, and then reverse the back side printing. It is safe, non-invasive, non-contaminating and the danger of imprinting in the imprinting. How much powder is sprayed, and it can be printed directly with origami and cutting. The quality of the CCD camera on the printing machine is reflected in the early reaction, the ink color is dark, and the automatic printing pattern is simulated. The error of the human judgment or the reaction is too slow, which is very important in the high-speed rotary machine. Use no horizontal printing, no need to use moist water quality stability and no VOC emissions are more environmentally friendly. Online cold ironing and casting can increase the added value and reduce the handling of the processing in one go.
In the future, there will be a small amount of digital printing, and it can be used for printing on less than two or thirty sheets to nearly one hundred sheets. It is very convenient to print, and it is not necessary to print on the CTP version. How much, such as Amazon does not use inventory books to order, in the future, using the network, cloud transfer files, scattered files are printed in various places as needed.
Using CAD design, CAM to make samples of cutting products and small-volume production, it is not necessary to use printing plates and die-cutting proofing. It is also an energy-saving method. After only a few thousand or hundreds of them, the cost must be changed to have a version and a knife. Modular high-efficiency production, which needs to be measured, but digital technology offers us another reasonable choice in small-volume cartons or POP production.
The second session was delivered by Professor Lu Zhizhong from the Department of Industrial and Qualifications of the University of Success: Innovative Information Application - Intelligent Energy Saving Solutions.
First of all, the impact of using cloud technology and the Internet of Things for energy management. The dynamic and highly available network services used today are the fifth generation of network technology, with Iaas, Saas and Paas, respectively, to control resources. To enable our energy and resources to generate diagnostics, services and better performance under management and control. For example, there is a software company with 2,500 servers and 250 cabinets, which costs 4.5 million yuan per month. In the first phase, the burden was reduced to 1,500 servers with a burden of only 2.7 million yuan. In the second phase, only 500 servers were left, leaving only one-fifth of the original 900,000 yuan. It can be very effective in analysis and processing. "Energy saving" is the common norm and ethical requirement of members of today's society. How to expand, time and space compatibility, wisdom and continuous innovation, how to reduce the use by 1% every year. Electricity, such as air-conditioning at 26~28 °C with fans, is an effective way to be comfortable and effective in saving electricity, and conduct energy-saving evaluations and awards in government agencies and schools. Indoor air quality management practices will also be implemented in confined, semi-closed and mass transit spaces.
In response to the increase in industrial electricity consumption of about 30%, some of the technology industry, steel, cement, paper, textile industry, electricity consumption increased by 35%, plus the previous lower than the peak power consumption, how good Use cloud technology and electricity-using places to centrally control the remote and near-end power consumption, and analyze the places where the power consumption is unreasonable. If there is abnormal heating in electrical appliances, transmission lines, sockets or switches. At the time, it indicates that there is a problem with the way of using electricity. There are many factors, such as the extension of the extended length of the extension cable, and the use of the power socket to increase the power consumption. If the overheated appliance or line is burnt, the fire is more likely to occur. When the fire occurs, there will be irreparable loss to personnel and property. In the statistics case of the fire department, the fire caused by improper use of electrical appliances or wiring problems As much as 34%, smoking and artificial arson are about 12% each, so the management and control of electricity consumption can not only save energy and reduce carbon, but also manage it to prevent terrible fires.
It is often difficult to calculate the reasonable contract capacity by using the contracted amount and the flow of electricity. However, reducing the contract capacity can also effectively reduce the expenditure of electricity tariffs, and maintain good production efficiency. Previously, manual control of large load machines was carried out. At the same time, a large amount of overload at start-up, the load is high and low, and the fluctuation of the load is low, so that the load difference is small, and the electricity load is not increased due to the high load default. The planned power load operation reduces the change to avoid overload and can be lower. Safe and rational production under the contract capacity. Therefore, the main power consumption station management in the printing machine room can use a lower energy-consuming motor, electric heating to UV lamp to change UV LED or reduce UV curing. Effective monitoring, fire prevention, disaster prevention detection and automatic alarm sprinkling operations for the environment and air conditioners, the introduction of efficient and rational production of electricity and energy-saving production, replacement of old energy-consuming air-conditioning, motors, centralized management of air-conditioning, Air supply and air supply. Therefore, only the human perception or unattended, often cold air is too cold, the temperature is not high, cold air, cold air filter blocked air supply and other inefficient energy consumption operation, if there is management analysis, it is easy to reduce air conditioning energy consumption, lighting And office appliances, computers and interface devices should be turned off when they are used in real time or when they are not in use. Using P-IES energy-saving management, using the energy storage plus monitoring two-pronged approach, shifting the peak load to the ionization peak period can stabilize the peak power burden. Using P-IES system management 365 days a year can reduce the labor cost of manpower management, and it is difficult to manage human resources. System management can be scheduled, can be set and take care of safety, transparent use of electricity information, distribution of friendship work and timely closure of unused lighting, air-conditioning, warning before the contract capacity is exceeded and danger can be prevented. The introduction cost of the P-IES system is not high, but it can collect electricity information in the first stage. On the one hand, it can monitor the other side to establish the electricity consumption mode, and the second stage can reserve energy, such as ice making and energy storage during the off-peak period. At the peak, the ice storage cooling or electric energy and heat energy are released. In the third stage, the electricity process is arranged, the peak power consumption is reduced, the production is lower at the peak electricity price, and the control is controlled to avoid waste of electricity. After the normal power mode is established, the abnormal situation will warn or power off, so that the management is very effective. In the introduction of P-IES, it can save 10~15% of electricity, and it also takes into account safety, comfort, energy saving and efficiency. Use the network to create electricity consumption arrangements and supervision, and achieve energy-saving and efficient production.
The third session was led by Dr. Zheng Xuhui, an environmental protection expert at the Printing and Research Center: the development and future of the printing industry under the environmental protection trend.
Environmental protection, energy conservation and carbon reduction are the world's issues. Europe, the United States, Japan, and China have all adopted environmental protection and energy conservation standards. In the economic planning of the 12th Five-Year Plan in 2010, China has also integrated the printing structure adjustment and the green printing system. Eliminate outdated printing processes and production capacity, and carry out effective resource control to reduce environmental load shocks. The printing industry is sustainable, with high quality, high efficiency and high environmental friendliness. How to recycle resources under effective use, low pollution, low energy consumption and low carbon emissions reduce the cost of enterprises. The environmental protection laws and regulations related to the printing industry, the pollution prevention and control law has a. Water pollution prevention and control law. b. Air pollution prevention and control law. c. Noise Control Law and other control items. Waste treatment and recycling, a. Waste cleaning method. b. Resource recycling and reuse method. c. Green Procurement Law. International environmental trends and environmental management of enterprises have a. greenhouse gases. b. Save energy. c. Low carbon emissions. d. Four items such as environmental education.
The whole Taiwan is subject to the Water Pollution Law, which has 14,000 businesses, factories and service industries. The printing industry is also among them. The discharge water is managed by the classification of surface water bodies and water quality standards. There are Class A to Class E on the land. Provisions for the content of harmful substances such as heavy metals, pesticides, and cumulative hazards. Protecting the living environment includes pH, pH, DO, BOD, SS, Escherichia coli, NH3-N and TP, etc., containing oxygen, suspended solids, and chemicals. There are six standard projects for onshore sewage discharge, each with a water temperature lower than or equal to 35?C. The PF value is between 6 and 9, that is, slightly alkaline or slightly weak acid above and below PH7. COD chemical oxygen demand is 100mg/L. BOD biochemical oxygen demand 30mg / L. SS suspended solids below 30 mg / L. The ADMI has a true color chromaticity of 550 or less. The E. coli population must be below the specified value. In the case of the detection of penalties, Article 57 may be punished on a consecutive day, and Article 66(1) provides penalties for violations. The prescribed six discharge standards, according to Dr. Zheng’s opinion, are print prepress specifications, not the discharge water standard of the printing machine room. The printing machine itself does not have much water consumption, and the wet water itself is evaporated in the air. It is not washing water, so there is no water discharge in various printing methods. No emergency measures were taken on the penalty, including heavy sentences and life imprisonment and fines of less than 5 million yuan. There is a penalty of not more than 5 years and a fine of 2 million yuan or less. There are also penalties for hazardous waste water that is allowed to be discharged, injected into water bodies, and soil. In the penalty of refusal to stop work, legal persons, responsible persons, natural persons and agents will be punished. Those who fail shall be improved and apply for reexamination inspection within the time limit.
In terms of greenhouse gas emissions, GHG has harmful substances such as CO2 carbon dioxide, CH4 methane gas, N2O nitrous oxide, HFCS fluorocarbon carbide, PFCS perfluorocarbon, SF6 sulphur hexafluoride, including global warming, ozone hole, Acid rain and other impacts, especially in recent industrial countries, their energy and harmful substances are rapidly increasing emissions due to rapid increase in industrial production, resulting in the earth's climate anomalies, ozone layer destruction, harmful radiation intrusion and acid rain damage to humans and crops. The list of greenhouse gas inventory, the organization's greenhouse gas emission sources, absorption summary, emissions, and emission reductions are managed. Although Taiwan is not a member of the United Nations and is not a signatory to the Kyoto Protocol, we are working hard to reduce energy and reduce carbon emissions under international environmental protection demand. We will increase energy efficiency by more than 2% in the next 8 years. In 2015, energy intensity will decrease by 20% compared with 2005. the above. The target of carbon reduction target emissions returned to the 2000 emissions in 2025. China has set a three-stage reduction strategy to promote greenhouse gases, and voluntarily check the log-in reduction. Stage I is forced to check voluntary deductions and Stage II performance standards to offset transactions. Stage III total control exchange transactions, domestic and foreign exchanges in carbon rights sources, carbon trading, balancing carbon rights emissions and carbon reduction rights. In the discharge, the Scopel unit directly discharges such as fixed generators, power engines (pushing equipment power), various boilers and incinerators, gas welding equipment, thermal energy equipment to discharge CO2, CH4, N2O, process exhaust gas combustion tower, such as The waste secondary combustion or catalytic combustion of the commercial rotary machine produces CO2 and CH4. When used in official vehicles, the internal combustion engine produces CO2, CH4, and N2O emissions. The use of electric power indirect energy to purchase indirect emissions of CO2, CH4, N2O, and other emissions.
Promote carbon footprint calculation in the environmental protection to establish a "carbon label", the second phase develops low-carbon products that are in line with ISO 14067, uses low-carbon labels, and cooperates with the Research and Development Center and the Art Department of the Taiwan University of the Arts to promote "lithographic printing." The certification of environmental labeling has the following drafts and current specifications. The application should be prepared as follows:
Applying for environmental labeling in the printing industry can save, save water, save heat resources, and reduce wastage of water and CO2 emissions. Reduce waste on waste paper and ink usage, increase production efficiency and reduce costs. Green environmental protection stamps can occupy a favorable position in government or domestic green procurement, break through barriers to green trade barriers, be friendly to people and cities, identify low-carbon cities and sustainable development.
Before the end of the meeting, Chairman Chen Zhengxiong made a comparison between the printing industry and printing media in terms of communication and publicity functions and electronic media. The electronic media has a good speed and breadth of dissemination. Some people use a computer to read a copy. In newspapers, the energy consumed in one hour is enough to print one newspaper, and the carbon emissions of electronic media consume electricity. The power medium carbon and oil used are non-renewable energy sources. The raw materials of paper media come from the storage of artificial forest carbon. The photosynthesis of trees absorbs carbon to release oxygen. Therefore, basically, the paper is used once and recycled pulp is also very environmentally friendly. 70% of the paper used in Taiwan comes from recycled pulp. In the pulping process of boiled wood, a lot of black water is produced, which is also concentrated into a combustible "black liquor". As a boiler biofuel, it is said that China uses 100 million tons of paper per year, of which recycled pulp is About 55%, and each paper mill entering China must have a huge afforestation base, and hundreds of thousands of acres to two or three hundred acres of fast-growing forest planted as their own pulp source, with fast-growing, silver acacia, There are many willows, etc., so there is also a large carbon storage right. Printing is based on paper media, and it is also a material that can be recycled, and it is very friendly to the environment under the papermaking industry strategy of forest, pulp and paper. The digital printing process of the printing industry itself is shortened, and the digital printing can greatly reduce the use and production of processes and pollutants, and achieve a more environmentally friendly situation. How much POD is printed according to the demand, is also an environmentally friendly, material-saving, waste-reducing One of the methods.
