The flexo or flexographic printing press is used commonly in the food packaging industry. The flexo or flexographic press is commonly associated with the plastic industry as many of the food packaging products use plastics. Besides the food packaging industry, the flexo printing press is also associated with industries including paper bags, carton and cardboard box, medical packaging, sanitary product labels, and the diaper industry. In recent years the flexo printing press is also found in the process for printed electronics manufacturing such as RFID, OLED lighting, functional substrates, circuit boards, and sensors. The Flexo press can print on various substrates or materials. This includes porous substrates such as paper, carton and cardboard. For non-porous substrates family including PE, PET, PP, and aluminum. The substrate is fed into the flexo press in a roll form from the unwinder unit. The tension of the substrate needs to be controlled with precision as it moves through the printing and drying units. The capability to main a precise substrate tension makes all the difference in print quality. This is a crucial disguising point for great flexo press and mediocre flexo press. Any tool will have its advantage and disadvantage and flexo press is no different.
CI press means a type of printing press used in multicolor flexo graphy in which a single large diameter common impression cylinder supports the substrate as it contacts a series of adjacent plate cylinders, which lay down successive colors.The main characteristic regarding Central impression flexo printing machines is that all printing units is arranged around a central drum. Here is a photo of an 8 color printer. it can print on PE, PP, OPP, PET, Paper. As it can be seen from the photo the printing units surrounds the drum. This type of press offers a high print quality and registration accuracy. Registration accuracy is when the ink combinations is aligned precisely on the substrate. Flexographic printing machines (often abbreviated as flexo press) perform a printing process which utilizes a flexible relief plate to transfer ink to printed substrate. Every printing job will require its dedicated set of plates. Flexo CI presses use a central drum which is common to all colours as counter impression roll. Flexo presses are used to print on different supports: plastic films, paper and aluminium foil. Flexo printers CI (Central Impression) are especially suitable in markets which require process jobs and flexibility (involve productions of small lots). In particular, technological improvements of last 15 years have re-shaped CI flexo presses both in their mechanical construction and in its controls. This improved their printing quality, drastically reduced change over times and consequently downsized their "minimum economical lot".
Flexographic printing machines (often abbreviated as flexo press) perform a printing process which utilizes a flexible relief plate to transfer ink to printed substrate. Every printing job will require its dedicated set of plates. Here are some advantages of it as folloeings:
Gearless Servo Flexographic press has become increasingly popular among the printing and packaging industry. A Servo Flexographic press is able to maintain print quality, reduce startup time and waste better. Many know that gearless servo presses are more precise when it comes to color registration and impression control when compared to a geared press. But why is it more precise? When is it more precise? Are there any other advantages besides being more precise? In this article we will understand why a servo gearless is more precise, we need to understand what is affecting the print precision in the first place. The accurate synchronization of the anilox roller and the plate cylinder at each print deck plays an important role in print precision. In the flexographic printing process, the anilox roller contacts the plate cylinder that carries the plate with dot patterns that form the print image. During the contact, ink is transferred over from the anilox roller over to the dot patterns. To be able to provide a constant ink coverage is crucial to the print quality and this depends on maintaining consistent motion between the surface of the anilox roller and the plate cylinder. Whenever the print cylinder moves faster than the anilox roller, less ink is transferred to the print cylinder, resulting in a light section In the printed piece.
The Gearless CI Flexo Printing Machine is suitable for printing such packing materials as polyethylene, polyethylene plastic bag glass paper and roll paper etc. And it is a kind of ideal printing equipment for producing paper packing bag for food, supermarket handbag, non-woven bag, vest bag and clothes bag, etc Here are some Characteristic as followings:
