Inkjet version - now print directly on your Archival Gold CD-Rs from your CD-compatible inkjet printer. The innovative materials found in eFilm Archival Gold CD-R's make them one of the most reliable storage mediums available. Typically CD-R's are known to deteriorate quickly due to Earth's common elements such as: ultra violet light, heat, and humidity. Using an accelerated aging process to test the longevity of CD-R media, eFilm Archival Gold CD-R's have been shown to safely store your images for more than 300 years. The patented Phthalocyanine dye is the most critical component of the CD-R because it is where your data is stored. Your CD burner creates pits in the dye layer when it burns a CD-R and your digital information is stored in these pits. The Phthalocyanine dye reacts quicker to the writing laser than dyes found in most CD-R's on the market, thus making sharper pit edges and making your CD-R easier to read by CD drives. Compared to Cyanine and Azo dyes found in the majority of CD-R's on the market, Phthalocyanine dye lasts significantly longer when subjected to the harmful effects of UV light, heat, and humidity. Gold is one of the most inert elements on earth and Delkin incorporates 20? of 24k gold into every eFilm Archival Gold disc. Gold's inert characteristics prevent oxidation, a common cause of failure to most CD-Rs. Along with the Phthalocyanine dye and gold reflective layer, eFilm Archival Gold CD-R's provide the most extreme protection for your digital images from environmental degradation. Features: Patented Phthalocyanine dye formula that gives a storage life of 300 years Gold is one of the most reflective robust elements on Earth. More than 20? of 24k gold in every CD-R Maximum resistance to the harmful effects of oxidation, a main cause of failure to optical media.
