2. Degredation By Humidity
Most ILFORD photo inkjet papers have high resistance to changes in humidity. As a general rule, when using Original Equipment Manufacturers ink, pigment ink prints do not show any colour change up to very high humidity (> 95% r.h. or relative humidity), whereas dye ink prints are stable up to 80% r.h. However, very low humidity (<20%) can make materials brittle.
- Keep prints between (> 20% r.h. < 65% r.h.).
- Avoid heat and high humidity over longer periods.
3. Heat Degredation
ILFORD GALERIE media is not very sensitive to higher temperatures (up to 35°C/95°F), and is not affected by the moderate temperatures found in most homes however the following recommendations are still advised.
- Keep prints below 60°C (140°F). Such high temperatures can occur, for example, if prints are left in a car during the summer.
- Keep prints <30°C (86°F) for long term storage in homes.
- Avoid high temperature and high humidity combinations.
- Avoid contact with other heat sensitive materials that could transfer onto the paper such as wax, oil and glue.
4. Degredation By Pollutants
ILFORD media is designed to allow the easy absorption of inks. However, this means that some environmental pollutants may also be absorbed.
Keep prints framed, in an album or sealed with non-contaminant materials (for example PE plastic, PET, archival board, cotton etc).
Contact with certain paper products (cardboard, paper etc) can transfer contaminants and should be avoided for longer term storage, use plastic sleeves or archival cardboard when possible.
Avoid contact to rubber products, most of which can stain prints.
5. Degredation By Water
Whilst ILFORD photo papers and many inks are moderately water fast, coloured liquids may stain the print if they come into contact with the surface.
- Avoid water spillage. If it happens, let it dry or remove gently with a cloth without rubbing and leave to dry naturally.
- Coloured liquids such as tea, coffee, ketchup etc. may stain a print. If this happens, immediately wipe off after a spill.
6. Scratches And Mechanical Damage
The surface of photo prints can be scratched and damaged if handled roughly. Pigment ink prints are generally more sensitive to abrasion than dye ink prints or unprinted paper.
- Avoid touching the prints with fingers.
- Keep the surface away from abrasive materials.
- Do not touch with a sharp tip.
