Archival Gold Layering Protects Photos Below the Photo Layer
- Phthalocyanine dye is long lasting, used by photo professionals nationwide, archives photos your entire lifetime.
- 24k Gold layer reflective coating, (instead of silver), protects a disc with a scratch-armor layer, other discs omit.
- Lacquer layer over the gold prevents peeling and plastic rot – a common problem among ordinary store-discs.
- Diamond protective layer applied to the lacquer will prevent scratches, not found in ordinary store digital discs.
Estimates of Aging Endurance is Based on Effects of Temperature, Relative to Humidity
In general, the test consists of placing samples in an environmental chamber at specified temperature and
humidity levels for 5 different "stress conditions" (shown below). A stress condition is defined by, for example:
2000 hours (in 500 hour segments) at 85% relative humidity and 80 centigrade temperature. Temperature and
humidity "Incubation" periods are reached gradually with the use of ramp times. This is done to avoid a shock
condition where bubbles can form in the media (CD) due to rapid transition of temperature.
5 Stress Conditions are Defined During Disc Testing to Meet Delivery Requirements
Test Cell numbers are Stress Tests in an Incubation period, minimum total time, minimum equilibration duration.
Equilibration is the time spent at ambient humidity before removal from the chamber.
Test Cell# Test Stress # of Samples Incubation hours Minimum Total Hours Min. Equilibration hrs.
1. 80C, 85% RH 10 500 2000 6
2. 80C, 70% RH 10 500 2000 5
3. 80C, 55% RH 10 500 2000 4
4. 70C, 85% RH 15 750 3000 8
5. 60C, 85% RH 30 1000 4000 11
Before and after, each incubation period is tested for error rates for Max-BLER for CD's and Max-PIE8 for DVD-R.
Failure is defined by error rates that exceed Orange Book standards defined by Sony/Philips, DVD-R specifications
defined by the DVD Forum. Due to the length of a test, results from Test Cell number #1 is used: 80C / 85% RH.
Life expectancy is estimated according to ANSI guidelines based on the use of the Eyring models which is a
mathematical equation derived from thermodynamic laws.
The following is a conclusion of 5 separate test periods, first test cell used in summary
Tested at eFilm - these estimates are based on results from industry standard tests subjecting discs to 85%
relative humidity and 110 degrees Celsius for 2000 hours. The Light Fastness Test shows that eFilm tested
Archival Gold to withstand the full spectrum of light, same as the sun, for 100 continuous hours without damage.
Our competitors' discs, with cyanine dye, begin to deteriorate after only 20 hours and fail at 65 hours.
Archival Gold is produced with Phthalocyanine dye under strict manufacturing conditions insure data
is preserved per each disc, is as tested to last from 100 years to 300 years under normal conditions.
Archival Gold is Lab Tested for Aging and Endurance with Extreme HIgh and Low Temperatures
Recording condition temperature -15 - 35 C, Humidity 45 - 75 %RH lower than normal
Playback condition temperature -5 - 55 C, Humidity 5 - 95 %RH lower than normal
Transportation condition temps -20 – 60 C, Humidity 5 - 95 %RH, test period 2 weeks
Storage condition temperature 5 - 30 C, Humidity 8 - 60 %RH, aging test 300 years
