Accurate calculation and automatic control of ink quantity is very important to improve the image quality of color newspaper. Calculation method for color newspaper ink quantity based on Particle Swarm Optimization Algorithm is studied in this paper to overcome the shortage of inaccurate calculation for ink quantity. Based on the principle of basic Particle Swarm Optimization Algorithm, by introducing adaptive inertia weight and shrinking factor to improve the convergence ability of the algorithm, the improved algorithms are used to solve this problem and the results show their validity. This method can control ink layer thickness more precisely and it provides an available method for color newspaper printing to match colors.
