Every print fades eventually. Light, air and moisture all break down colourants over time, and no coating or ink makes a print permanent. What you can do is slow the process considerably, so that colours stay true for as long as reasonably possible. The approach combines choices at four stages: printing, finishing, display and care.
What causes fading
- Ultraviolet light from sunlight and some artificial sources is the biggest single factor.
- Visible light also contributes, especially at high intensity over long periods.
- Ozone and airborne pollutants can attack some colourants, particularly in busy urban or industrial spaces.
- Heat and humidity speed up chemical changes in inks and media.
Start with the right ink and media
Pigment inks are generally more lightfast than dye inks, which is why they are the standard for fine art and photographic reproduction. Latex, UV and eco-solvent inks are widely used for display work. Media matters too: some papers contain optical brighteners that can yellow or change appearance with time. If longevity is a priority for a job, choose an ink and media combination with a good reputation for permanence and check the manufacturer’s information.
Add a protective coating
A clear coating places a barrier between the inks and the environment. Colourjet includes integrated UV inhibitors to help protect against premature fading, and also shields the surface from water, chemicals and abrasion, which matters because a scuffed or stained print often looks worn long before its colours fade. Landor Liquid Lamination is designed for prints from pigment fine art, latex, UV and eco-solvent printers. As with any solvent coating, test on your own ink and media first. Browse the options on our coatings page.
Display thoughtfully
- Keep valued prints out of direct sunlight wherever possible, or use blinds and window films.
- Choose lighting with low UV output and avoid placing spotlights very close to the print.
- Avoid hanging prints above radiators, in steamy kitchens or bathrooms, or near heat sources.
- Rotate temporary displays and promotional graphics where practical.
Outdoor work
Outdoor signage and graphics face the toughest conditions, with full sun, rain and temperature swings. Here, protection is close to essential. Plan for the expected display period, choose inks and media intended for outdoor use, and apply a coating or laminate suited to exterior conditions. Be realistic with clients about how long an outdoor graphic will look its best, and avoid quoting a lifespan you cannot support. Our indoor vs outdoor guide covers this in more depth.
Care and storage
Prints in storage should be kept dark, dry and at a stable temperature, ideally flat or loosely rolled with acid-free interleaving for fine art. Clean coated prints gently, as harsh cleaners and abrasive cloths can wear the surface over time.
