Kodak 3383, 2383 manual Processing Conditions, Laboratory AIM Densities LAD, Reciprocity

PROCESSING CONDITIONS

Process this film in Process ECP-2D. No change in process sequence is required.

Because there is no rem-jet to remove, VISION Color Print Film offers the potential for eliminating the current prebath chemicals and reducing water usage. However, exercise care if the rem-jet removal steps are eliminated, as replenishment rates will change dramatically if dry film enters the developer directly. Soluble dye buildup in the seasoned developer will also increase. Greatly reducing water flow will lead to increased concentrations of total process effluent from the laboratory, which may have regulatory implications. For further assistance, contact your Kodak engineering representative.

The antihalation dyes used in VISION Color Print Film are decolorized and removed during processing. Although most of the dye is removed in the developer, complete removal is also dependent on the “tail end” solutions, such as the bleach.

To prevent static during projection, maintain a relative humidity of 50 to 60 percent in the projection room.

It is important that you maintain a “clean” process: proper solution mix and storage procedures to minimize “tar” formation, process machine and recirculation designed to minimize aeration (e.g., submerged racks), periodic cleaning of racks and tanks, proper maintenance of squeegees and wiper blades, and efficient filtration.

LABORATORY AIM DENSITIES (LAD)

To control your process, use Process ECP-2 control strips for this product available through your local sales representative.

To aid in color timing and curve placement, negative originals should be timed relative to the Laboratory Aim Density (LAD) Control Film supplied by Eastman Kodak Company. The LAD Control Film provides both objective sensitometric control and subjective verification of the duplicating procedures used by the laboratory.

For print films, the LAD patch is printed to a neutral gray of 1.0 visual density (1.00 Equivalent Neutral Density) on the processed print at the setup lights.

The Status A densities are:

	R	G	B
Density	1.09	1.06	1.03

For more information, see KODAK Publication No. H-61, LAD—Laboratory Aim Density.

RECIPROCITY

You can print this film on a variety of printers, ranging from slow step-optical printers to very high-speed continuous contact printers used for release printing. Exposure times

may range from 1/10 of a second to almost 1/3000 of a second, with little or no change in tone scale. For printers that change exposure time during printing, new speed reciprocity correction should be used. KODAK VISION Color Print Film / 2383, 3383 has improved fade and dissolve characteristics. Printers with mechanical fader cams will no longer need to use filter correction to achieve neutral color balance with fades and dissolves. Printers with programmable light valves will need to reprogram the fade and dissolve algorithm in the printer to obtain neutral color balance with fades and dissolves. Consult the printer manufacturer for the proper test procedure to obtain the appropriate corrections.

PRINTER RECOMMENDATIONS

Pictorial Printing

The printer setup for KODAK VISION Color Print

Film / 2383, 3383 is similar to EASTMAN Color Print Film 2386 / E / 3386 / E, with little or no change required.

For example, if you use an additive-type printer, such as a Bell and Howell Printer, Model 6123, to print originals, you can use a 90 V dc lamp, a KODAK WRATTEN Gelatin Filter No. 2B, a KODAK Heat Absorbing Glass, No. 2043, a printer speed of 240 feet per minute, and the printer settings in the table below:

Beam	TRIM	Neutral-Density	TAPE
		Filter
Red	14	0.40	25
Green	14	0.50	25
Blue	11	0.60	25

You can also expose this film with a subtractive printer with a KODAK WRATTEN Gelatin Filter No. 2B, a KODAK Heat Absorbing Glass, No. 2043, and suitable color-balancing filters (KODAK WRATTEN Color Compensating Filters).

Sound-Track Printing

Analog and digital sound-track printer setup and control procedures for KODAK VISION Color Print Film / 2383, 3383 are similar to Film 2386 / E / 3386 / E, with little or no change required.

Analog variable area positive sound tracks of silver plus dye usually restrict the exposure to the top two emulsion layers by inserting KODAK WRATTEN Gelatin Filters No. 12 and No. 2B2 in the light beam. The optimum variable-area sound-track density for the print is between 1.1 and 1.8 (read at 800 nm). You can achieve excellent frequency response and a high signal-to-noise ratio in this density range.

For a variable area positive sound track of silver plus magenta dye only, printed from a negative sound track, restrict the exposure to the top two emulsion layers by

2.You can omit the No. 2B Filter without affecting the sound quality. Using this filter is an operational convenience to

conform with printer setup for other products that require it.
