KODAK EKTALURE PAP E R 

KODAK EKTALURE Paper is a medium-speed, single contrast, warm-tone, double-weight, fiber-base paper. It is designed for making enlargements and contact prints with reduced illumination. EKTALURE Paper is particularly suited to portraiture and to display and salon work. 
You can also use it for copy and restoration work, fine-art applications, and hand-coloring. 
It is available in G surface in a variety of sheet sizes. 

 
FEATURES  BENEFITS
  • Warm brown-black  image tone 
  • Exceptional warm tones for prints without toning

SAFELIGHT RECOMMENDATIONS 
Use a KODAK OC Safelight Filter (light amber) in a suitable safelight lamp with a bulb of 15 watts or less at least 4 feet (1.2 metres) from the paper. Minimize safelight exposure to avoid unwanted quality changes. Be especially careful if you use other types of safelights. 
See KODAK Publication No. K-4, How Safe Is Your Safelight? for information on safelight testing. 
Note: Do not use a KODAK OA Safelight Filter (greenish yellow). 

STORAGE AND HANDLING 
Store paper in a cool, dry place (preferably at or below 70F [21C] and at a relative humidity of 30 to 50 percent). High temperatures or high humidity may produce undesirable changes. Always rewrap unused paper in its original packaging (the outer box as well as the inner wrapper) to protect it from light and moisture. Avoid or shield the paper from exposure to radioactivity or x-rays. 

EXPOSURE Light Sources 
Expose this paper with tungsten or tungsten-halogen enlarger lamps. You can use other light sources, such as cool-white fluorescent lamps, mercury-vapor lamps (cold light), or cathode-ray tubes. For best results, make test prints to determine the exposure time for each light source.

&A hardening fixer may improve release on ferrotyping drums. 

Stop Bath 
Bathe prints for at least 15 seconds at 65 to 75F (18 to 24C) with continuous agitation in KODAK EKTAFLO Stop Bath, KODAK Indicator Stop Bath, or 48 mL KODAK 28% Acetic Acid and water to make 1 L. 
With EKTAFLO or Indicator Stop Bath, discard the solution when the color changes to a purplish blue. Change Acetic Acid and water stop bath after approximately twenty 8 x 10-inch prints per litre (eighty 8 x 10-inch prints per gallon). 

Fixing 
Fix prints at 65 to 75F (18 to 24C) with frequent agitation. With KODAK Fixer and KODAFIX Solution, fix for 10 minutes if you use a single bath. If you use two fixing baths, fix prints for 5 minutes in each bath, draining for 5 seconds between baths. 
With KODAK Rapid Fixer or POLYMAX T Fixer, fix for 5 minutes if you use a single bath. If you use two fixing baths, fix prints for 21/z minutes in each bath, draining for 5 seconds between baths. 
Note: Using a hardening fixer makes toning less efficient. For the same amount of processing time, you'll see less of a toning effect. 

Washing 
Wash for one hour in running water at 50 to 86F (10 to 30C), interleaving the prints carefully and frequently. The wash-water flow rate should provide at least one complete change of water in the container every 5 minutes. The KODAK Automatic Tray Siphon provides proper movement and agitation during washing. 
Avoid prolonged washing and soaking times to minimize physical damage to the prints. 
To reduce time and conserve water, use KODAK Hypo Clearing Agent before washing. Transfer the prints, with or without a previous rinse, to the clearing agent. Following the Hypo Clearing Agent, wash prints for 20 minutes with agitation and normal water flow. 

Drying 
Remove as much surface water as possible from prints and dry the prints in a dust-free place. Place prints face down on cheesecloth, fiberglass, or plastic screen racks; between photo blotters; or on a belt dryer. Dry at temperatures below 180F (82C) to avoid excessive curl and changes in the gloss of the lustre surface.

TONING 
Treatment with a toner extends the life of prints that may be exposed to oxidizing gases or subjected to adverse storage or display conditions. KODAK Toners will protect prints whether or not they produce a tone shift.
