| Stable and accurate printing register will minimize web loss.
Twin nip rollers installed at both end of printing section keep the web tension constant through all the process.
The web proper tension can be set easily on the touch screen according to printed material. Consequently the waste of web can be reduced. |
Easy operation and shortened make ready time are suitable for large variety and small amount production.
|
All settings can be done automatically only by inputting necessary data such as printing speed, print length, cutting ratio of Flat Die and necessary options on the touch screen monitor.
Easy plate change is suitable for large variety and small amount production. | |
Various attachments can be added for combination printing. |
In order to satisfy changing needs of today's market, a wide range of
attachment is available as option such as flexible die which enables cutting
into complicated shapes and forms, flexo printing unit, flexo varnishing unit,
hot stamping unit, laminating device and sheet cutting unit. |
| Hot foil stamping unit is an available option. Accurate digital heat control per ± 1 degree makes it consistent regardless of the running speed. |
