VARN washes remove ink from rollers and blankets in sheetfed offset printing. Select by ink, rubber and cleaning method. Compare the applications and limitations of each variant below.
Check also the full range of VARN chemicals and general offer of WIT printing chemicals.
Provide the ink name and rubber type: NBR, NBR/PVC or EPDM. Then specify the cleaning method and press model. Conventional printing wash does not have to be compatible with EPDM or UV inks.
For automatic washing, check the installation instructions and the required manufacturer’s approval. Do not dilute the product according to the rules of another wash. When washing by hand, take into account water, evaporation time and residues on the blanket.
Compare applications and product selection conditions below. Download available technical data sheets (PDF, ENG). If you need a safety data sheet or information about another variant, please write to us.
Sheetfed offset washes
Manual and automatic washing after conventional inks. The preparation is mixed with water and contains corrosion inhibitors.
Do not use on EPDM. In an automatic system, use undiluted product according to the instructions.
For manual and automatic washing
Roller and blanket wash, described in the manufacturer’s data sheet from 2017. Choose it according to the type of ink and washing system of your machine.
In automatic washing, use without dilution, after confirming compatibility with the system. When washing by hand, the card allows the addition of up to 20% water. The flash point is above 60°C (class AIII). Confirm the conditions of use for the currently supplied variant.

Regular ink wash removes ink, but is not a substitute for any stain wash. For calcium or glass transition, choose the appropriate one VARN care chemicals. Water roller cleaner also has a separate use.
Check the technical data sheet, safety data sheet and machine manual before use. The abbreviation NBR stands for nitrile rubber, NBR/PVC mixture, and EPDM is another type of elastomer. The name “UV” alone does not confirm the compatibility of all these materials.
Only if the card allows both inks and a specific rubber. Don’t choose a product based solely on smell or evaporation rate.
Provide the machine model, ink type, roller and blanket rubber, and washing method. WIT will confirm the correct variant, packaging, availability and pricing. We set the price for a specific product and quantity.
