Note: * This engraving was developed in 2001, however it was not accepted as an improvement of 60° by the industry. Following the GTT Technology enhancement, the Longcell was revisited by our competitors to try and compete with the emerging GTT patent. Various tricks and breaks in the wall construction of Longcell has created an engraving that increases the ink transfer and volume which assists cheaper / poor board quality. *

- Can print dirty on fine text and edges.
Channellox
Scope / Best working Environment
The Channellox engraving is best suited to:
- Thick viscous inks and coatings such as UV.
Note: * The Channellox was developed to break the walls running top to bottom to allow ink to flow more freely within the engraving. *

Guaranteed Consistency
In flexography, the staggering combinations of plate, ink, press, speed, operator – and even climate – all conspire to reduce predictability on press. As the heart of the flexo press, the anilox roll is the foundation of the printing process. Therefore, to limit the possible variables at the ink transfer stage — engravings, ceramics, TIR tolerances, volume, wear — will provide the stability required to achieve print consistency and press efficiency. Through high QC standards and innovation, Apex helps remove the anilox from the list of variables. With the advent of Apex’s GTT engravings, ink release has never been more predictable.
