Processed prints made on this film will show less than
10-percent image dye loss, even after several decades of storage at room temperature and 50-percent relative humidity.
COLOR BALANCE
Color print film is balanced to be printed from a color negative, duplicate negative, or internegative, using either an additive or subtractive printer. Black-and-white (silver image) negatives can be printed to yield a fairly neutral image, although slight coloration may be seen in highlights or shadows.
Overall filtration should include a UV-absorbing filter, such as a KODAK WRATTEN Gelatin Filter No. 2B.
FILM STRUCTURE
KODAK VISION Premier Color Print Film / 2393 is coated on an 120 micrometre (0.0047-inch) ESTAR Base featuring a proprietary electrically conductive anti-static layer, a polymeric scratch-resistant backing layer, and a process-surviving backside lubricant. Unlike rem-jet, the anti-static layer remains with the film after processing, eliminating the electrostatic attraction of dirt particles to the processed print, even at very low relative humidity. A very thin polymeric backing layer coated on top of the anti-static layer provides superior resistance to scratches, cinch marks, and abrasion of both raw stock and processed film. The backing layer also contains process-surviving lubricant and matte to optimize winding and transport characteristics.
An antihalation layer containing proprietary solid particle dyes is coated under the normal emulsion. These dyes offer superior protection against exposure by light reflected back from the support surfaces, minimizing color fringing in critical scenes like white titles and night scenes with automobile headlights. The antihalation layer also provides improved resistance to safelight edgefog, since it is coated between the support and the emulsion layers, and absorbs any support light-piping from the edge of the roll.
The imaging layers are coated on top of the antihalation layer and they contain new patented emulsion and coupler technology. The bottom layer is sensitive to blue light, and produces the yellow dye image. An interlayer controls diffusion of developer and development by-products. The next layer is sensitized to red light, and yields the cyan dye image. Another interlayer is coated on top of it. The top image-forming layer is sensitized to green light, and produces magenta dye. The very thin topmost layer (SOC) provides protection from scratches. Process-surviving lubricant and matte are used in the SOC to optimize winding and transport characteristics. The emulsion layers also contain absorber dyes to precisely control film speed and reduce intragrain light scatter, increasing sharpness and further reducing halation. These soluble absorber

IDENTIFICATION
KODAK VISION Premier Color Print Film / 2393 raw stock has the typical blue-purple emulsion color of print film. Slight batch-to-batch variations in raw stock color are normal. The back side of the raw stock has no rem-jet, appears dark blue to slate-gray, and has a slight iridescence.
This film has slightly less surface gloss than processed 2386 / E / 3386 / E Film. When viewed by reflected light, the back side exhibits a slight iridescence, with subtle color bands due to the dichroic nature of the very thin back-side coatings.
After processing, “2393 KODAK” is visible along the length of the film, along with strip number and date codes.
This film is available on ESTAR base only. Most 35 mm applications use KS-1870 (ISO type “P”) print perforations.
DARKROOM RECOMMENDATIONS
You can use sodium-vapor lamps with a KODAK No. 8 Safelight Filter / dark yellow in safelights providing general darkroom illumination. The filtered sodium-vapor lamp provides the best visual efficiency with the least visual effect on the film.
If you are using a low-wattage tungsten bulb for task-lighting, filter it with a KODAK 8 Safelight Filter / dark yellow. You can use amber Light Emitting Diodes (LEDs) (590 nm peak wavelength) for minimal task or path lighting; however, do not use them for prolonged or general darkroom illumination.
