More and more newspaper printing factories
and offices had started to manage newspaper printing quality with lean management, adopted the method of process control to improve the quality of newspaper printing. Controlling with the nodes of all process flow is the key to improve the efficiency of process-control.
The printing effect of pictures determines the aesthetic of the newspaper in a great extent. Therefore, our factory requires not only guaranteeing the basic printing quality of newspaper, but also requires being full in color and rich in layers. Excelsior is our seeking goal.
Our factory requires not only the prepress staff is familiar with the printing process; understand the relevant parameters of printing, but also high artistic accomplishment and aesthetic. This is the only way to accurately analysis and flexibly processing all kinds of pictures.
In addition, the color restoration ability of the printing staff is also an important factor to affect the final printing effect of the picture. Therefore, the printing effect of the picture is closely related to the prepress processing and the printing processing personnel.
Accordingly, we convene all the prepress processing and printing processing personnel to carry out the technical exchanges. Analyze and solve problems. Continue to urge them to make technical improvements, and arrange technical personnel to analyze the printed daily newspaper picture quality, and select some excellent and some inferior pictures, rewarded and punishing at the same time to the related prepress processing personnel.

But due to the impossibility of each ink path are put a group of control strip, so the control method is relatively rough. Can only guarantee the basic balance of color, and no obvious color deviation. But the advantage is not increase process time and cost, good feasibility and effectiveness.
