General
Unlike conventional plate making production of direct laser engraved printing plates and rollers is a digitally controlled 3D process. Aspects of the formation of the image like the first step height, total relief height and shoulder width can all be controlled separately from the image detail.
Laser engraving occurs as a cylindrical process. Materials capable of being coated on roller or sleeve bases can be engraved with continuous seamless designs. The materials that can be applied to a roller or sleeve base include a wide range of photopolymers and elastomers..

High Definition
Printing traditionally uses halftoning to represent continuous tone (grayscale) images. Laser engraving can take advantage of the 3D aspects of a printing plate to offer a higher level of control than conventional platemaking processes. Due to the digital nature of the laser engraving process traditional halftone data can be combined with grayscale data in a number of ways. This adds control over the 3D details of an engraving, first step height, total relief and shoulder width, to the realtime imaging of the plate or roller. Significantly, this hybrid data can also extend the total number of grayscale (tone) equivalents a laser engraving can emulate without processing images at extremely high resolutions. Halftone line counts depend on the characteristics of the plate material being engraved and the type of laser used for engraving.
Materials
LASERLIFE LITTLEJOHN can supply and engrave a variety of plate materials. As laser engraving is not a photographic process, laser engraved plates can be made of photopolymer or opaque materials like natural or synthetic elastomers. Laser engraving offers the printer the widest range of available plate materials.

Plastic Rollers
We coat various types of plastic synthetic coatings for the printing industries. Our two main synthetic coatings are Corvel and Rilsan. Synthetic materials which provide resistance to chemicals while offering excellent abrasion, wear and impact resistance with a low coefficient of friction
Ceramic Rollers
Using the latest plasma system we are able to produce dense, hard wearing coatings that will withstand harsh environments. The diamond lapped super finished process yields a high quality ceramic surface which delivers excellent hydrophilic properties ideal for dampening rollers in Lithographic printing.

Ceramic rollers are also used for metering rollers, feed rollers and transfer rollers.

Metal Rollers
A variety of metals sprayed includes Nickel Chrome, Aluminium, Tungsten carbide with nickel matrix, Copper, Bronze, Brass, Molybdenum, Stainless Steels, Stellite and Zinc. The coatings are used widely for wear resistance, corrosion resistance and structure restoration
Copper or Bronze Coating
  • Superb electrical and thermal conductivity.
  • Affinity to water or inks
  • Thick coating can be sprayed
  • Readily machineable and will produce an excellent finish.
Nickel Chrome Coating
  • Resist corrosive gases and oxidation temperatures up to 1000 °C, it can be used to resist heat and prevent oxidation scaling of conventional low alloy steels.
  • Used as an oxygen barrier under sprayed coatings of ceramics. and is also used as a bond coating for ceramics. The corrosion is significantly inhibited with this material.
  • Machineable.
Zinc Coating
  • Used to protect iron and steel against corrosion.
  • Suitable for alkaline environment.
  • Comparatively cheap coating.
None Stick Coating
Recently we have developed a new coating process and material that has been very well received. It is our non stick coating. This thermal sprayed coating not only has the non stick properties but also is very wear resistant and excellent against corrosion. The non stick surface offers:
  • Excellent release which minimises the build-up of residue from manufactured product onto coated production equipment. It releases what-ever it comes in contact with. (Examples: ink, glue, food, paint, varnish, adhesives, etc.) An excellent release property (i.e. mould release).
  • The release coatings have lower friction which decrease the drag of product over stationary or guiding parts. They also provide durability and conductivity of static.
  • These coatings are designed for ease of cleaning which minimise accumulation of residue and product pick-off. Cleaning is quick, easy, and operator friendly.
Ceramic
Coatings

Any of various hard, heat-resistant, corrosion resistant coatings made up of non-metallic materials.

Chromium Oxide
  • Very hard coating, the hardness is 70-75Rc.
  • Excellent resistance to corrosion, sliding wear and particle erosion.
  • Very dense coating, porosity is less than 2%. Insoluble in acids, alkalis and alcohol.
  • Dissociates easily, hence ideal for laser engraving and widely used for the wear protective coating of printing rolls which are subsequently laser engraved
Aluminium & Titanium Oxide
  • Good abrasion and erosion resistance.
  • Easier to grind than Chrome Oxide coatings.
  • Better hydrophilic property than chrome oxide coatings.
  • Less brittle, more ductile than Chrome Oxide coatings.

LASERLIFE LITTLEJOHN can offer a wide range of cleaning solutions to help you maintain or restore the performance of your anilox rollers.
Corrective Engineering
After continuous usage, it is quite often rollers are worn out on bearing journals and damaged on keyways and threads. Some shafts can be snapped off after excessive force and imbalance.

LASERLIFE LITTLEJOHN offers customers comprehensive corrective engineering to salvage damaged and worn-out rollers: The service includes:

  • Repairing bearing journals, threads and keyway journals
  • Replacing broken shafts
  • Straightening bent journals
  • Dynamically balance rollers to customer specified RPM
  • Repairing internal bores
  • For rollers used in an extreme corrosion environment, build-up roller bases with a stainless steel layer to prevent corrosion on coatings

The corrective engineering jobs are carried out by methods of welding, hard-chrome plating, machining, grinding and dynamical balancing etc. They are done both in house and out sources to guarantee high quality standard and customer satisfaction.

New Steel Bases
For many years, LASERLIFE LITTLEJOHN have manufactured new roller bases for all type of machines. We manufacture new bases for narrow and wide web as well as corrugated and offset machines.

We are able to either visit on site to measure up the existing roll bases or measure in house at our facility. We then produce an Autocad drawing which the customer approves before commencement. We also have many hundred drawings on file. It is crucial that we use the best possible but affordable metals to ensure the roller will last for many years. We always stress relieve the barrel and journal than machine to required surface finishes.
