Abstract

In relation to the recent rapid development of web-offset printing, fluting in web-offset printing is becoming a serious quality issue requiring an urgent solution. Our study on this issue identified that fluting in web-offset printing is a phenomenon where an imaged area had been buckled by a compressive force caused by a combination of tension and contractile force during the printing operation. Also, the number of the fluting in web-offset printing is determined by the compressive force, the size of the imaged area and the stiffness of the paper.<BR>On Dec. 2001, we started to produce a new paper product which is free from the fluting in web-offset printing on. It's designed to have small contractile force which is occur by drying of web-offset printing process.
