Advantages of Disc Printing Technology and Process Control (II)

CD UV printing process

Multi-color screen printers using solvent-based inks have not been successfully accepted by the market. We cannot tolerate a high-speed machine that always stops to wipe the blocked mesh. This creates many potential problems: Production The efficiency is seriously affected, the color of the disc is not uniform, and a large amount of waste products appear. This is the reason why it must use UV ink, and the use of UV ink will greatly complicate the structure of the machine.

The successful use of solvent-based inks in pad printing does not mean that we have not paid attention to the progress of UV technology. In fact, the development of UV pad printing technology has been continuously carried out both theoretically and practically. UV pad printing inks will make the print coating better quality, more wear resistant, and higher gloss.

CD UV printing process:

Optical Disk Conveying - Disc Overlay - Disc Inspection - Printing on White - UV Curing - Four-Color Pad Printing - UV Curing - Finished Discs

The above pad printing process has been proved to be feasible by practice, but it can be seen that it does not protect the picture layer by UV varnish coating as offset printing. This is the current status of pad printing. Many manufacturers finally use a monochrome screen printer to apply a layer of UV varnish to compensate for this defect.

It is not particularly troublesome to install a UV curing device on a multi-color pad printing machine because multi-color screen printing machines have had very successful experience. The key is that we must look for specialized UV pad printing inks. If the UV printing technology of optical discs still needs further study, we must find a more mature and stable optical disc UV printing ink.

Optical disk printing technology is a relatively young technology. Therefore, it must learn from the features of other mature printing technologies in order to continue to mature. In the 21st century, the development of engineering technology has a wide range of significance in terms of integration and deepening, and printing technology is no exception. In terms of integration, there is a close relationship between printing, screen printing and offset printing. The formation of a more mature printing technology should receive attention; in terms of deepening, any printing technology is constantly drawing high-tech blood. The direction of full recognition by operators, environmentalists and business managers.
