A Technological Breakthrough for LAMs Digital Flexo Plate imaging
Woodpecker Nano Surface Micro Structures are applied at the imager output avoiding the need for costly RIP options. Woodpecker Nanopatterns are perfectly symmetrical and the finest available for LAMs layer digital flexo plates. Structures are applied to the highest linescreen ruling (dots) with no need for a protection border. Nano screening is not object or subject based and requires no decisions at the RIP stage.
Surface Micro Structures for Flexo Plates
In continually improving flexo print quality, it is recognised that microscopic structures on the print surface of the plate can improve the ink lay-down giving smoother higher density solids. Another benefit has been found to be sharper printed dots in half-tone screens, reducing or eliminating premature ‘dot-bridging’. In combination, good surface micro structures (SμS) greatly enhance the appearance of flexo print.
Woodpecker Nano Compared to Most Common LAM’s Layer Alternative
Inherently finer achievable surface patterns certainly improve solid ink density and smoothness compared with standard plates or even other lower frequency structures. In addition to SID improvements, half-tone dot screens are greatly enhanced by reducing or even eliminating ‘dot-bridging’ effects that further limit flexo print quality. Nano’s perfectly symmetric Surface Screen Patterns from 2000dpi and above are fine enough that the need for a protection border or ‘Edge Definiton’ (a different pattern) around half-tone dots or fine details is unnecessary.
These finer structure arrays reduce the risk of damage particularly on small half-tone dots as they fit closer-together for more uniform dot sizes. Dot and fine detail edges are more predictable as there is no ‘one line off, one line on’ effect in the image. Furthermore the close and uniform structure greatly reduces the risk that the surface pattern will interfere with the main dot line-screen and cause moiré effects.
Being able to run full range dot-screens or vignettes is very advantageous as it avoids the need to use a ‘fade-out’ or ‘protection border’. Both of these functions can give protection for small dots but the transition from screened to solid dot is almost impossible to hide in all images without a screen break often visible somewhere. Such problems make the screening settings ‘object based’ thus more decisions required at the RIP stage. Fine Nano screening allows simple output giving optimum results for every job with no decisions required or variants to consider.
Woodpecker Nano Surface Micro Structures
Woodpecker Nano utilises the high resolution ThermoFlexX optics, usually used to output 5080dpi image files. Careful and accurate laser beam control allows repeatable and stable implementation of these fine screens. It has been established that an input file resolution of 2000dpi gives an optimum surface micro structure output for this optical path, already in place in most ThermoFlexX large format imagers. Working with 2000dpi image files still provides excellent quality flexo print results. Image files are dramatically reduced in size. Fast transfer and storage of files all becomes an easier proposition contributing to production efficiency. Very importantly, high imager productivity is maintained....

No other digital imager offers the unique Vacuum Slider Concept (VSC). Based on smart design, printers can insert the plate in the advanced clamping system and slide the vacuum setting toward the plate edge, and they are done! No more need for special tape constructions or cutting plates to fit dedicated vacuum zones, thus, allowing the use of cut-off scraps!
The Xeikon ThermoFlexX solutions are unique in their use of 5080 PPI resolution, resulting in:
Xeikon ThermoFlexX imagers are designed for smooth and productive operation. The advanced clamping system facilitates ergonomic and easy plate mounting. The standard vacuum drum and optional hybrid vacuum/magnetic drum assure accurate plate positioning and optimal exposure of flexo and letterpress plates. The integrated display enables fast, user friendly and reliable control of the imager.
