| 中文摘要: |
| 基于生命周期评价对大连地区胶印企业所采用的CTF和CTP制版工艺进行了环境影响量化分析，指出了2种制版工艺所致的环境影响类型、严重程度及成因。结合相关经济指标，进一步对二者的环境效益进行对比评价，提出了改善建议。研究结果表明：CTP工艺环境影响相对较小，其环境影响总量是CTF的83%，但CTP与CTF相比的绿色比值仅为0.88，说明CTP工艺的环境效益尚处于较低水平；控制工艺过程耗电量、提高能源利用率和降低版材成本是提高制版工艺环境效益的重要途径；当CTP工艺所构成的内部成本下降15%以上时，会大大提高其市场竞争力。 |

| Quantitative analysis on environmental impacts resulted from CTF and CTP plate-making technologies of offset printing enterprises in Dalian area was carried out by using life cycle assessment. The types, severity and causes of the environmental impacts generated by the two plate-making technologies were pointed out. Environmental benefits of the CTF and CTP were compared and evaluated by combing with relevant economic indicators, and the improvement suggestions were put forward. The research results showed that the environmental impacts caused by CTP process are relatively small, the CTP's environmental impacts in total is 83% of CTF's; however, green ratio of CTP to CTF is only 0.88, which shows that the environmental benefit of CTP technology is still at low level; control of power consumption, improvement of energy efficiency and reducing cost of printing plate are important ways to improve the environmental benefit of the plate-making technology; when internal cost of the CTP is cut down more than 15%, the CTP's market competitiveness can be greatly enhanced. |
