One of the main reasons to coat a print is so that it can be cleaned. An uncoated inkjet print can be marked by a damp finger; a coated one can usually be dusted and wiped without harm. That said, a coating is a protective layer, not armour, and the way a print is cleaned will affect how long it keeps looking good. This guide is written so you can pass the advice straight on to your customers.
Before cleaning anything
Make sure the coating has fully cured. A print that has only just been coated may be dry to the touch but still soft underneath. Follow the curing guidance on the coating’s technical data sheet, and if in doubt, wait longer before handing the print over or cleaning it.
Routine dusting
For most prints, regular light dusting is all that is needed. Use a soft, clean microfibre cloth or a soft brush. Work gently and avoid pressing dust into the surface, as grit dragged across a print can cause fine scratches over time.
Removing marks
- Dust the area first to remove any loose grit.
- Dampen a soft cloth with clean water and wring it out well. It should be damp, not wet.
- Test on a corner or less visible area first.
- Wipe gently, without scrubbing.
- For stubborn marks, add a small amount of mild, non-abrasive detergent to the water and repeat.
- Wipe again with a cloth dampened in clean water to remove any residue.
- Pat or wipe dry with a clean, dry, soft cloth.
What to avoid
- Abrasive pads, scouring creams and paper towels, which can scratch or dull the surface.
- Solvent-based cleaners, strong alcohol or ammonia-based products, unless the coating manufacturer confirms they are suitable.
- Soaking the print or spraying cleaner directly onto it. Apply to the cloth instead.
- Pressure washing outdoor graphics, which can lift edges and damage the surface.
Colourjet is designed to protect against water, chemicals and abrasion, but gentle cleaning will still extend the life of any coated surface.
Canvas and fine art
Textured surfaces trap dust in their weave. A soft brush works better than a cloth here. Avoid pressing hard on stretched canvas, as it can leave dents or stretch the fabric. Customers should also check the back of the canvas from time to time for dust and signs of damp.
Handling and display
Handle prints by the edges or frame, ideally with clean cotton or nitrile gloves for fine art. Keep prints out of direct sunlight and away from heat sources, and they will stay looking their best for longer. Our guides on preventing fading and moisture protection go into more detail.
