Press Maintenance Programme
 Regular preventative press maintenance is often the most
overlooked factor in relation to producing quality offset printing
on a consistent basis.
 Without a scheduled regular roller and blanket maintenance
programme, you could struggle to achieve the consistent
quality that you need to compete.
 Inadequate or no press maintenance means higher costs in
waste board, ink, overheads, lost press time and in extreme
cases, lost customers.
 Regardless of your spend on expensive press technology it is
impossible to attain high print quality if your rollers cannot
transfer ink effectively due to glazing.
 Are you aware of the factors that can cause these profit losses?
Blanket Maintenance Programme
 Blankets should be treated weekly to remove any glaze buildup. The following procedure is recommended to ensure highest
quality printing performance and maximum blanket life.
Blanket Maintenance & Wash Up
1. Wash blanket to remove wet ink with a Varn water miscible
wash such as Varn V60 Plus (KV10-0V6G).
2. Apply Varn Take It Off (KU40-0TFG-01B7) or Varn Revitol (KU401RVG-01AF) and leave on blanket for at least 10 minutes.
3. Wash off with a Varn water miscible wash such as Varn V60
Plus (KV10-0V6G).
4. For heavily glazed blankets or light embossing, wipe over with
Varn Super Rubber Rejuvenator (KU40-0SRG-01F9).

Roller Maintenance Programme

Deep clean roller wash-ups should be performed weekly to maintain the rollers
and revitalise their surface.

Special attention should be paid to roller ends to prevent build-up of glaze
and/or board fillers.

Additional Maintenance Tips

These small investments in time and chemistry will pay big dividends
in quality printing, profitability and longer equipment life.
 Use Varn True Blue (KU40-5TBG-01AF) plate cleaner/ conditioner to clean

chrome dampening rollers and dried ink from impression or back cylinders.
Keep your fountain solution circulators free of ink, paper dirt, calcium, fungus,
etc., Flush system with Varn Fountclean (KT10-5FCG) regularly.

Don’t wait until performance/quality levels drop off before taking
action.

With a regular maintenance programme (x mins per week),
performance & quality will remain high.
