Heart of Flexo printing –Anilox cleaning



The anilox roller is the very heart of the flexographic printing.  If all other prepress conditions are perfect, but the anilox roller is not clean, you cannot produce consistent colour and print quality.  Keeping your anilox rollers clean after each job, ensures the printer’s ability to produce repeat print jobs with consistent colour and print quality in minutes rather than hours.


As the lines on the anilox are getting finer and finer, the need for quality cleaning is getting larger and larger; otherwise quality printing cannot be obtained.

Especially the new laser technologies present new challenges to the printers. The deeper cells can exasperate plugging issues. Plugged   anilox rolls cause inadequate ink distribution, poor colour densities, difficulties in getting the right colour and waste of time, ink and substrate. Smaller cells mean a more delicate cell structure. Delicate cells are more easily susceptible to damages because of improper handling, doctor blade scoring and poor cleaning methods. Pads, abrasive cleaners and brushes are loosing their effectiveness in deep or small cells.

Because of the above mentioned issues, printers cannot wait with cleaning of their rolls until the aniloxes cannot perform anymore. The market is simply getting too competitive and uncleaned aniloxes cause inconsistent print quality, increased downtime, excessive waste and thereby loss of competiveness.

The proactive approach to maintenance of the aniloxes and thereby also in the end to be more competitive is to:

  • clean the rolls after each job
  • keep a regular maintenance schedule on rolls
  • clean the rolls immediately after removal from the press and before storage
  • keep new rolls clean from day no 1. 

Today everyone knows that the aniloxes need to be clean to get an optimal printing quality. Properly cleaned anilox rolls however also reduce set up time, reduce press downtime, minimize waste of ink and substrate, improve productivity and increase the roll life. Therefore it is a must to clean the rolls. Because of the finer lines it is also a MUST to find a safe, gentle and automatic cleaning method, that will cause no wear or tear on the delicate aniloxes.

Flexo Wash uses a safe and gentle cleaning method that does not harm even the most delicate rolls. In fact the cleaning method offered by Flexo Wash means that you can both deep clean the rolls and wash them on a daily basis without harming even the finest rolls. The eco - friendly cleaning liquid used for anilox cleaning dissolve the ink built up in the anilox cells done by   heated  cleaning   liquid  wash followed by high jet water spray.  First the ink /varnish is softened chemically and then by force of the water spray the deposits are dislodged.  The liquid applied is filtered and re-circulated. There is no abrasion caused whatsoever thus preserving the integrity of the anilox roll surface. Being   cleaning liquid they are not size limited hence have the ability to penetrate the high screen count anilox cells. The cleaning and rinsing process is completed by drying with compressed air. No manual handling during the entire cleaning process thus avoiding any damage to the anilox roll.


It does not matter if the anilox roller is wet or dry.  It does not matter if you need to clean water based, solvent and/or UV inks, adhesives, acrylics, polymers, lacquers, varnishes, laminates, etc. The Flexo Wash FW Anilox Cleaning Systems incorporate “plug ‘n play simplicity”:

  • Set the time, close the lid and push the start button. The whole cleaning process starting with liquid spraying, rinsing with high-pressure water and at the end drying by means of air will run through automatically.
  • The systematic cleaning process is safe and harmless to the anilox rolls, employees and the environment
  • Cell volume is completely restored – in a few minutes
  • Cleaning solution is captured and filtered for re-use again and again - lowering costs
  • Simple maintenance: Change the filter monthly and clean the liquid tank every half year.
