Currently, most stroboscope have internal and external triggering mode, the internal trigger mode is used to manually adjust the frequency; external trigger mode for automatic tracking, but with the need to use an external sensor, generally Hall proximity switches and photoelectric switch two kinds. 

1 stroboscope internal trigger mode of operation is as follows 
a. estimated velocity of the print pattern 
b. adjust the flash estimate of the frequency of the above 
c. trimming flash frequency until relatively stationary or slow-moving 
 
2 stroboscope external trigger mode operation is as follows 
a. install an external sensor 
b. Setting parameters stroboscope 
 
     Due to the high intensity strobe flash, not in front of the eyes irradiation, for flexible packaging printing industry, we must pay attention to the elimination of direct and reliable static grounding strobe. 

Stroboscope unique internal structure can eliminate the visual result of high-speed motion blur caused to help inspectors for high-speed operation of the production line of products for visual inspection. Stroboscope can be installed on the press, slitting, rewinding machine, lamination machine, hot stamping machine, laminating machine, seizure of goods, coiling machines and other machines to help detect can print clearly and accurately detected and tangential effect. The stroboscope installed electronic microprocessor, is also designed with the control button, you can automatically adjust the strobe frequency based on line speed, so that inspectors can select automatic mode. After using stroboscope, even the smallest defects, such as: non-continuous film missing, adhesive material, stains, white spots, stripes, color blur, chromatic allowed, were missing, color and layout alignment and other issues, can be detected to quickly find. Use strobe signal devices can greatly reduce the defect rate, increase production, and improve the detection accuracy and increase customer satisfaction. 

Stroboscope applications for over 20 years in the history of flexible packaging printing industry, its intuitive test results have been recognized by the majority of users, for a long period of time, stroboscope will continue to serve the flexible packaging printing industries.
