IPI's 6500-square-foot facility on the RIT campus is one of the finest and best-equipped centers in the world for testing imaging and recording materials and for conducting preservation research. The lab is divided into several distinct areas:
Microscopy Lab
For both care and appreciation of images, it is important to understand the physical nature and layer structure of photographic objects. In this laboratory, equipment exists for the scanning, imaging, and cross-sectioning of traditional and digital prints and negatives. Images made here are used in creating publications, lectures, and didactic materials in various formats.
Incubation Lab
IPI's incubation laboratory contains sixteen temperature/humidity chambers and three dry ovens that provide controlled conditions for accelerated-aging tests.The lab also has two walk-in environmental chambers that can maintain a wide variety of controlled temperatures and humidities.
Light Fading Lab
In this area, the display life of images is tested using simulated daylight or office lighting. The room is equipped with a 50-kilolux daylight Weatherometer, one 50-kilolux fluorescent unit and one 10-kilolux fluorescent unit for testing the light-fastness of photographs, ink jet prints, and other materials.
Wet Chemistry Lab
Activities in the chemistry lab include solution preparation, wet-scratch testing of photographic emulsions, testing of alkaline reserve and acidity, and pH determinations on both film and paper.
Pollution Lab
The pollution lab houses two custom-built, 21-cubic-foot chambers for studying the effects of such air pollutants as sulfur dioxide, nitrogen dioxide, hydrogen sulfide, and ozone on imaging media and enclosure materials. These chambers are designed to withstand the rigors of constant exposure to varying levels of corrosive gases and extremes of temperature and humidity, and to maintain constant temperature, humidity, and gas concentration while recirculating and mixing the test atmosphere.
Instrumentation and Physical Testing Lab
Tests on the physical properties of paper and plastics are performed in this area. Materials can be tested for such properties as brittleness, curl, folding endurance, tear and scratch resistance, and color. Measurements are made on commercial equipment using standardized procedures. IPI also has facilities for constructing specially designed equipment for specific applications if the required test apparatus cannot be found commercially.
Calibration Lab
Before it is shipped out, every PEM is checked and calibrated in this area.
Library and Study Collection
IPI has an extensive library on photographic history, technology, and preservation. The 100,000-photograph study collection features examples of the various imaging processes that have been used over the past one hundred fifty years.
