High speed product positioning is crucial to the success of printing. In order to achieve high-speed positioning, it is necessary to provide high-speed position locking input to the driver or motion controller, so as to capture the accurate spindle position when encountering the positioning mark. The difference between the front and back positions is used to calculate the actual distance between the positioning marks. That is, the distance is compared with the theoretical distance between the marks, and a correction amount is calculated. Then, the correction amount is substituted into the slave axis motion curve.

The time required from the detection of the positioning mark to the application of the correction amount is very important for the production of high quality products. This time is entirely dependent on the motion controller used for the application, and may also be affected by the technology used (for example, some digital motion control networks have a transport lag that must be compensated, which may not be acceptable in some applications). In some applications, it is necessary to use a special positioning algorithm, such as averaging the correction of several or many products, filtering the correction, or not applying the correction in some segments of the motion curve. The motion controller shall also be able to properly handle web splicing and missing positioning marks.

A typical 10 color printing line with basic configuration has more than 65 closed-loop motion control axes. In larger lines, there are usually more than 100 shafts. In the past, each axis was mechanically driven. Now, the updated control system improves the positioning performance and reduces the positioning accuracy to half of the old system. These control systems have high flexibility, can deal with special tasks, and provide unlimited variable repetition. Instead of the speed matching method discussed above, it enables the user to increase or decrease the speed of the plate roller relative to the web to change the repetition length.

These improvements can also make the speed faster, the maximum speed can be increased from 1200 FPM to 2000 FPM, flexographic printing process can achieve higher speed. The average time for a printer to switch from one task to the next is reduced from 4-6 hours to 30 minutes, or even less in some cases. The manipulator with motion control and printing driving device positioning system has a great influence on the switching time. In the application, because the whole control system provides better diagnostic information, the machine production time can be extended.
