About

Cheshire Anilox Technology is a manufacturer of superior laser engraved ceramic Anilox rolls that improve the printing process. Established in 1992, Cheshire Anilox Technology has expanded progressively into many market areas, which includes flexible packaging, corrugated, label, envelope, can coating and offset. We are now established as one of Europe’s leading suppliers of Anilox rollers servicing a loyal customer base in over 100 countries worldwide. Cheshire Anilox Technology has invested in the latest Fibre laser systems, the most technologically advanced ceramic coatings and inspection and volume verification systems. Cheshire anilox rolls are produced entirely in house. This allows us to manufacture standard and custom rollers more efficiently and cost-effectively while maintaining the highest quality. Quality is closely monitored in all manufacture steps to ensure absolute consistency of each roll from end to end. This also gives us the flexibility of developing specialized manufacturing processes and meet tight delivery times. At Cheshire Anilox Technology we use the latest Fibre laser technology with state of the art optics that provide unparalleled control of the beam for high line screen engravings with consistent cell geometry and improved ink release properties. Our powerful 500 watt fibre lasers come with custom pulse which can produce unlimited cell designs allowing Cheshire Anilox Technology to develop new engravings for exceptional print quality, improved consistency and higher line screen definition.

Chesire offers multiple engraving types, such as:

MaxFlo

For many years the industry standard cell configuration has been 60 degrees. Due to new laser technology improved cell shapes have now been produced. The maxflo has evolved to offer many advantages with ink lay down and improved print quality.

The standard 60° engraving pattern has a honeycombed structure which offered good uniformity but due to its conical profile only released around 60% of its total volume. Problems would occur as the left over ink often congealed or dried causing plugging of the Anilox cells.

By stretching the cell shape the laser no longer focuses at the base of the cell, which in the past had created the conical effect. Instead the new technology multi-hits the cell walls creating a boat- shaped cell which is vastly more efficient at releasing ink, completely eradicating the cleaning problem of the past and allowing the printer to use a finer Anilox without loss of density or volume.

MaxFlo+

The concept of using channel engravings to improve ink transfer efficiency is not a new one. Channels have been used for many years as an effective means of increasing the ink flow within the Anilox improving transfer efficiency. However ink film consistency and uniformity was always more difficult to control in conventional channel engravings. The real challenge is to design a channel that can effectively control the volume of ink transferred as well as maximize ink evacuation from the Anilox. MaxFlo+ has accomplished both.

MaxFlo+ is a channel engraving that radically improves the ink flow within the Anilox engraved structure. There is no individual closed-up cells but a continuous cell structure which has 50% less land area than 60° conventional engravings. This offers a more efficient and finer ink distribution to the plate. More ink surface area is in contact with the plate which maximizes its inking in a more uniformed way. Engraving depth is shallower than conventional closed -cell engravings which greatly improves ink evacuation from the Anilox.

Some of the advantages of using MaxFlo+:

- Improved ink release and superior print quality with up to 10%
- Uniform coverage
- Pin hole effect is reduced
- UV spitting is reduced

EASYFLO

“EasyFlo” engraving has been specially developed for anilox rolls for flexo printing with UV polymerized inks. One of the most common problems with flexo printing with UV curing inks is the "ink spitting" effect. The viscosity of UV-cured inks is almost five times higher than that of water-based or solvent-based inks, which is why the ink collects and puts pressure behind the squeegee during printing.

Easyflo is a cell engraving system at an angle of 30 ° that allows a better uniformity of the ink between the alveoli of the anilox roller, reducing the pressure behind the squeegee and thus eliminating the spraying effect.

Another advantage of this engraving system is that the anilox rolls thus engraved transfer by about 10% than conventional anilox rolls engraved at an angle of 60 °.

EASYFLO HD

High opaque white is a common challenge in today’s flexographic industry. Recent developments in narrow web ink, plate and anilox technology allow printers to achieve the opacity of rotary screen whites.

Easyflo HD is designed to mimic the opacity of screen whites on film in one single pass. In order to achieve opacity levels above 80% a high volume of ink is necessary, this unique engraving technology offers an improved ink flow, efficiently distributing high volumes of ink resulting in an outstanding uniformity of coverage, increasing opacity and eliminating mottling and pin holing. Combined with the use of low viscous, fast curing, highly pigmented inks and hard capped plates, easyflo HD has proven it can hit opacity levels of 85% in on single pass running at 50-60m/min.

PROFLO

Innovations in all press components continue to raise the bar in Flexo printing allowing converters to match or excel the print quality of offset: HD plates are used with high pigment and fast drying inks and high-release ultra-fine anilox rollers.

HD flexo operates very fine plates which need to be used in conjunction with extremely fine anilox rollers to avoid dot bridging.

New advancements in coating technology are helping along with new generation lasers to make today possible the feasibility of producing such ultrafine engravings consistently as porosity is reduced to less than 1%.

Cheshire Anilox Technology has developed a new engraving, Proflo specifically for ultrafine screen specifications. It features a new improved cell profile that will provide a more consistent ink lay down while also eliminating the chance of uncontrolled dot gain. This high-release cell offers as much as fifteen percent additional ink compared to conventional engravings allowing printers to achieve high colour densities at extremely fine linecounts.
