Since it's introduction in 1970, Cinegel has continually developed and grown to meet the working needs of the professional. In 1974, Cinegel won an Academy Award for technical achievement. Deep-Dyed Polyester (Rosco Cinegel, GAM Filter) Like surface coated PET, deep dyed film begins with a roll of clear polyester. The film is passed through a bath of heated solvent suffused with dye. The solvent causes the PET film to swell expanding the polymer structure of the film and allowing the dye molecules to penetrate the surface. The film is then washed and the polymer contracts to its normal form, trapping the dye molecules below the surface. Compared to surface coating, more extreme temperatures are required to cause the dye particles to sublimate through the surface. Deep-dyed filters are, therefore, more resistant to fading than surface coated. Gels Are Not Returnable
