SYSTEM G38

This in-line colour control system PQA-W uses a CCD camera to acquire high-precision images. Colour data captured by RGB is converted to density values by our software. By using this density data to automatically control the ink keys, high-quality density control is achieved immediately after machine start-up.

KHS-AI start-up to targeted density rapidly, and PQA-W maintains this density during a run. KID display a wide variety of information about print monitoring, print images, PDC-SX, PQA-W, etc. PQA-W displays the measured data of the inline colour control, that is, the density status during printing.

In addition to density, G38 also automatically adjust the register, cut off, and paper width positions, allowing you to display the four types of trend information at the same time. This information serves as criteria for the OK sheet and can be a great support for crews to operate the high-speed printing press.

 This is Closed-loop automatic register controller with a uniquely designed area array sensor that reads up to 0.36mm register marks at speeds up to 17.8m/sec (3500 ft/min).

It combines the flexibility and unmatched plate register functions required to meet the requirements of the most demanding printing presses. We have adopted a new camera technology that is highly adaptable and virtually maintenance-free.

From the start of printing, the printer run the paper with a minimum number of sheets, reducing loss and improving productivity. Hardware has also been updated to achieve compactness and power saving.

The high-precision CCD sensor is used to control the paper position in the lateral direction. Komori's unique AI LINK function controls not only the lateral paper position at the outlet of the web guide but also the reduction of the wrinkle by feeding back the twisted paper amount to the Splicer. Additionally, the entire paper position between splicer and folder is controlled by cascading just before the folder, which allows you to reduce make-ready time and waste.

Komori cut-off controller automatically controls the cutting position. The digital image data loaded through PCC, and KHS-AI is analyzed to find out the contrast in the image to preset the optimum target. This function automatically finds the cutting position during start-up and maintains the position to reduce the number of wasted paper and to support the operator with less touch on the operating screen.
