Solvents used for cleaning offset press cylinders, blankets and ink systems represent one of the largest consumable costs in print workshops. Recovery machines can dramatically reduce these costs.
Solvents Used in Offset Printing
- Press cleaning solvent (specialty): 80β88% recovery
- IPA: Dampening system and cylinder cleaning, 92β96% recovery
- Acetone: Specialist cleaning applications, 90β95% recovery
- Naphtha/white spirit: Heavy oil and ink removal, 80β88% recovery
Calculation: Mid-Sized Offset Facility
A mid-sized offset facility with 4 presses consumes 5β10 litres of cleaning solvent per day β 150β300 litres monthly. With AR-120 and 85% recovery, 127β255 litres of monthly fresh solvent purchasing disappears.
π‘ Large format or web offset facilities can exceed 500 litres/month β annual savings at this scale are very substantial.
Ink Contamination Issue
Offset cleaning solvents typically contain ink pigment and oils. This contamination must be removed by pre-filtering before recovery. Pre-filtered solvent processes more efficiently and yields higher recovery rates.
Environment and Compliance
The offset printing sector, with high VOC emissions, is under close environmental scrutiny. Solvent recovery both reduces VOC and lightens disposal obligations.
β AR-120 use in offset printing facilities typically delivers payback in 6β10 months.
