Aiming at the empirical value problem of material demand planning loss value in printing production, this paper proposes a method to predict the loss value of printing process by optimizing Support Vector Regression. Firstly,the Pearson Correlation Coefficient is used to quantify the eigenvalue selection. Then, the Cuckoo Search algorithm is used to optimize the selection of super parameters of Support Vector Regression algorithm, and the loss prediction model is established. Finally, to verify the superiority of the model, it is compared with models of different eigenvalue selection schemes, optimization algorithms and regression algorithms. The experimental results show that the proposed loss prediction method has higher generalization and prediction accuracy, and the determination coefficient, average absolute percentage error, and root mean square error are 0.995, 0.005, and 1.969 respectively. It provides theoretical support for the follow-up related problems.
