Archival Care of Prints

It does not take much research on this topic to discover that the information available is very limited and very technical. The most current information on this topic can be found at Wilhelm Imaging Research. www.wilhelm-research.com. Their studies on image permanence are vast and in depth. 

Next, let's look at some generalities of longevity and preservation of printed images.

 

Protection of Printed Images

Photographers use a number of methods and substrates to print photographic images. The longevity of these images is dependent on many factors in manufacturing including paper selection, acidity of the paper and mounting materials, ink types, exposure to photographic chemistry and washing in the printing process.

 

General approaches to improve longevity during production of printed images include: 

· Minimizing long exposure to the chemical processing of prints

· Thorough washing after exposure to chemical processing

· Using coated papers for inkjet printing

· Use of printing inks that use pigment instead of dyes

· Printing on archival papers that are acid free

 

There are also factors affecting the longevity of an image once it is printed. These factors include exposure to light, humidity, temperature and handling.

 

General approaches to improving longevity of an image after printing include: 

· Minimizing exposure to light (particularly sunlight and fluorescent lighting)

· Minimizing exposure to humidity (40% or less is recommended)

· Minimizing exposure to heat

· Minimizing exposure to airborne pollutants

· Use of storage boxes and presentation mats that are acid free

· Storage of images in polyethylene, polyester or polypropylene sleeves

 

Long term storage of images is best with cold storage and low humidity.
