Environmental Protection from Photographic Materials in Graphic ArtsHiroyuki USHIROYAMA1998 Volume 35 Issue 2 Pages 36-41
Published: March 31, 1998
Released on J-STAGE: September 27, 2010
JOURNAL FREE ACCESSFor a long time, silver halide photographic film and paper have been employed in the graphic arts field. Since these materials are subjected to wet processing, which is not friendly to the environment, a decrease in the amount of processing wastes has been required. Furthermore, in January 1996, London Convention was put into force to prevent dumping of photographic processing wastes. Since then, a decrease in the wastes has increasingly been demanded in view of global environmental protection. In order to meet these requirements by each of the several photographic material manufacturers, introduction of products, and research and development have been carried out toward, in addition to the reduction in processing wastes, a decrease in packaging materials, improvement in recycling properties. In another aspect, dry film materials which require no processing solution have been developed and recently introduced into the market.View full abstractDownload PDF (1441K) -
Measures of Offset Inks Against EnvironmentToshimasa YAMANAKA1998 Volume 35 Issue 2 Pages 42-47
Published: March 31, 1998
Released on J-STAGE: September 27, 2010
JOURNAL FREE ACCESSEnvironmental pollution has been progressed on the earth scale. In Japan, We have been concerned with problems of groval warming, dioxin, industrial waste disposal as imminent menaces. It is now necessary to take measures against environmental pollution from the side of printing inks. Oil-base offset inks have become popular to use aromatic free solvent, mainly the naphtenic. “Eco Mark” has been authorized to this type of ink. The use of soy ink which can make decrease V. O. C is still limited in Japan. Clients which desinate to use soy ink together with recycled paper for the protection of environment will increase in the future. Paper containers have been adopted for ink cans which can be easily burned-up. They have good reputation.View full abstractDownload PDF (1746K) -
Energy Saving and Natural Resource Utilization in Printing IndustryTakayuki YAMAZAKI1998 Volume 35 Issue 2 Pages 48-53
Published: March 31, 1998
Released on J-STAGE: September 27, 2010
JOURNAL FREE ACCESSThe purpose of energy saving is obviosuly not to purchase energy saving devices but to keep the energy cost down. The goal of energy saving is accomplished by individuals keeping the goal in mind and try implementing it in daily work wherever possible.View full abstractDownload PDF (1547K) -
The Latest Life Cycle Assessment and a Case Study of Gravure PrintingHirotaka TSUCHIYA1998 Volume 35 Issue 2 Pages 54-63
Published: March 31, 1998
Released on J-STAGE: September 27, 2010
JOURNAL FREE ACCESSLife Cycle Assessment (LCA) is coming recently to public notice as a way of presuming the possible effects of products and services on the environment. Although the method is still under investigation, the packaging materials have been tried widely to assess through LCA. This paper describes the outline of LCA as well as a comparative case study between conventional solvent-based gravure printing and environmentally friendly water-based gravure printing by LCA. It is of highly importance to accumulate these case studies in order to enhance the accuracy of such simulative assessment as LCA.View full abstractDownload PDF (2160K) -

JOURNAL FREE ACCESSSome properties of coated paper influenced to the ink trapping, which is an important factor for printability of coated paper, were studied using overprintings printed with cyan and magenta inks. From the estimation of ink trap ratio by density measurements for commercial A2 coated paper, decreasing of ink trap ratio was observed by decreasing the interval time between 1st and 2nd color printing. Same method was applied for three kinds of coated paper which had different diameters (2.20, 1.50, 0.85μm) of ground calcium carbonate as a pigment and quantitative estimations were made. Pore size distributions of coating layers and time dependences of contact angles between coated paper and oil included in printing ink used in this study were also measured. From these results, it was shown that the interval time and the ink trap ratio at the starting point of decreasing the ink trap ratio was not concerned only with the coating structure of coated paper but also with the properties of pigment in the coating layer.View full abstractDownload PDF (1455K) -
