	abstract = {Abstract Increased demands for productivities and product-quality have been made since the arrival of the Information era, at the same time, all walks of life experienced an enormous change in the process, so does the printing industry. The traditional printing flow cannot meet the demands of market anymore, it doomed to be wash out gradually and will be replaced by the digital printing. By now, the competition among printing enterprises has been transferred to management competition. The enterprise of the lowest cost, the best quality and the fastest speed will be the market leader. In the entire printing process, the production scheduling problem which is concerned for a long time became more important. According to the characteristic of digital printing flow based on JDF, the scheduling problem for this flow was studied by genetic algorithm (GA) in this paper. Firstly, the process of printing scheduling parameter obtaining was introduced. The information of order which was put in by the customer was obtained by MIS system. And then, the information of equipments was obtained by the production process supervisory system. All parameters needed in the genetic algorithm program were summarized. Secondly, the genetic algorithm which has the ability of whole optimization was introduced. The important problem of GA was studied according to the production scheduling characteristic, the scheme of encoding and decoding was determined, the crossover and variation operation was select. The software system was realized by object oriented programming using JAVA. Finally, the printing scheduling task was described; a scheduling example was given to prove the feasibility of the scheduling system. And then, the process of JDF worksheet forming and the actual result returning were introduced.},
