CONTROL over the end product, a great concern of South China Morning Post's features editor Charles Anderson, has been greatly strengthened by Tai Po technology. Anderson said the old system of page layouts and selection of illustrations and then a compositing room finish, had been superseded. 'The new technology means we can plan pages on screen and we have a photo bank we can call on,' Anderson said, referring to computer pagination technology and the Post's new AP Preserver System. 'Because everything is now on line, we are in the process of bringing more usable photos into our computer system. 'But our greatest advantage is in quality control. We now have control over the design of our pages. Journalists involved with planning a page are as certain as they can be that the end result is what they want,' he said. 'The system increases the speed at which we can change pages around if required.'
