Color Print Film / 2393

RICHER COLORS ON THE SCREEN

Now, there’s a new choice in motion picture print ﬁlms— KODAK VISIONPremier Color Print Film. Aﬁlm with a different look. Richer blacks. More saturated colors. Cleaner performance. A ﬁlm worthy of the KODAK VISION Film family name.

The upper tone scale of VISION Premier Film is significantly higher in density than EASTMAN EXR Color Print Film, so shadows are deeper, colors are more vivid, and the image snaps and sizzles on the screen. The toe areas of the sensitometric curves are matched more closely, producing more neutral highlights on projection. Cinematographers can be more creative with lighting and exposure, and still see remarkable results.

BENEFITS FOR LABS

• Polyester base provides greater tear strength, durability, dimensional stability, and archival keeping

• Elimination of rem-jet (no carbon black or prebathsoluble binder)

• Potential for reduced chemical and water usage in processing

• Improved cleanliness on high-speed printers (less white dirt)

• Protectionfromstaticmarks prior to printing

• Reduced dirt attraction to processed prints and static protection prior to processing

• Better transport characteristics for processed ﬁlm

• Superior halation protection (no colored fringes in titles)

• Improved safelight edgefog protection for digital soundtrack area

• Improved fades and dissolves, and less propensity to safelight fog

• Extremely rich blacks, higher color saturation, and more neutral highlights on projection

• Improved laser subtitling

Likeits counterpart KODAK VISION ColorPrintFilm, VISION Premier Film is coated on a polyester base without rem-jet, for a cleaner process and cleaner screen images. We’ve incorporated a processing-surviving, anti-static layer to reduce dirt attraction, and a scratch-resistant backing layer to improve projection life. And there are no color shifts during fades and dissolves. So, from set tolab to screen, day to day, you’ll have more consistent performance.

These are not incremental improvements. They are quantum leaps forward in film technology. And with VISION Premier Film, you’ll have the finest motion picture color print film Kodak has ever made.

STORAGE

Unexposed print ﬁlm is not adversely affected by short-term storage at room temperature (less than 25˚C (77˚F).Store unexposed ﬁlm at 13˚C(55˚F)orlowerwhen storage exceeds 1 month. If refrigerated, allow the sealed can or foil bag to equilibrate to room temperature before opening to avoid condensation. Rebag unused raw stock and seal it in ﬁlm cans before returning it to refrigeration.

Process exposed film promptly. This film exhibits excellent latent image keeping. When exposed film must be kept several days before processing, the tone scale of VISION Premier Color Print Film / 2393 shows little change. Depending on the storage temperature, labs can compensate for the small latent image speed loss by increasing printer TRIMS slightly (a neutral increase of 1 to 2 printer points)ifthere is a longdelaybetween printing and processing. You can slow changes in latent image by storing exposed film at lower temperatures. For critical applications, such as sensitometric exposures used for process control, keep exposed film strips at 0˚C (32˚F) or lower.

For short-term “active” storage and projection of processed prints (e.g., commercial film exchanges and theatres), store at room temperature of 20 to 25˚C (68 to 77˚F) at 50 to 60 percent relative humidity. Avoid prolonged unconditioned storage at high temperatures or excessive humidity. For medium-term storage, store at 10˚C (50˚F) or lower, at a relative humidity of 20 to 30 percent. For more information on long-term storage, see KODAK Publication No. H-23, The Book of Film Care.

For extended-term storage (for preservation of material having permanent value),store at 2˚C (36˚F)or lower, ata relativehumidity of 20to30percent. Molecular Sieves*in a sealed can will provide additional benefit.

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.

EXPOSING LIGHT

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) ESTARBase 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, cinchmarks, and abrasionofbothraw 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 reflectedbackfrom the support surfaces, minimizing color fringing in criticalsceneslike white titlesand night scenes with automobile headlights. The antihalation layer also provides improved resistanceto safelight edgefog,since it is coated between thesupportand the emulsion layers,and absorbs any support light-piping from the edge of the roll.

IDENTIFICATION

KODAK VISION Premier Color Print Film / 2393 raw stock has the typical blue-purple emulsion color of print ﬁlm.Slightbatch-to-batch variationsinrawstockcolor 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.
