Supplementary Information on

KODAK EKTAMAX RA

Professional Paper

KODAK EKTAMAX RA Professional Paper uses colored

dyes to form black-and-white images in prints made from

color and black-and-white negatives. It is designed for

processing in KODAK EKTACOLOR RA Chemicals for

Process RA-4 along with color negative papers.

The information in this publication supplements the

information provided in the instruction sheet and in KODAK

Publication No. G-22, KODAK EKTAMAX RA Professional

Paper.

CHARACTERISTICS AND APPLICATIONS

Suggested uses for EKTAMAX RA Professional Paper

include intermediate applications for graphics reproduction,

displays, real-estate brochures, publications, press releases,

and portrait proofs. The paper may also be acceptable for

other applications in which long-term display and keeping

are not required. In applications that require archival or

long-term keeping or complete image neutrality, a traditional

black-and-white paper is a better choice.

STORAGE AND HANDLING

Store unexposed paper at 13°C (55°F) or lower in the

original sealed package. High temperatures or high humidity

may produced undesirable photographic changes. Storage of

unexposed paper at room temperature will produce a hue

shift over time (see “Effects of Storage Conditions”).

Avoid moisture condensation by removing the package

from cold storage the day before printing.

Handle paper carefully by the edges. The paper is

packaged with the emulsion side of all sheets facing in the

same direction. For complete light and moisture protection,

use the inner bag and the two-part cardboard box to store the

paper.

EXPOSURE RECOMMENDATIONS

The spectral sensitivity and printing speed of KODAK

EKTAMAX RA Professional Paper are designed to be the

same as those of KODAK PROFESSIONAL PORTRA,

SUPRA, and ULTRA Papers. Therefore, printing

EKTAMAX RA Paper should be very similar to printing

KODAK PROFESSIONAL Papers. If you are printing color

negatives and have a balance setup for those color papers,

you can use that setup for EKTAMAX RA Paper. An

adjustment of filtration from that balance will not change the

hue of EKTAMAX RA Paper, but it will cause a change in

contrast.

If you are printing black-and-white negatives onto

EKTAMAX RA Paper, two methods can provide suitable

results:

• Put a piece of processed D-min from KODAK

PROFESSIONAL PORTRA Film in the exposing beam

along with the filters you normally use to print color

negatives.

• To the filtration that you use to print color negatives,

add 35 units of magenta and 65 units of yellow filtration

to simulate a piece of film D-min.

If you do not have any processed D-min from

PROFESSIONAL PORTRA Film or a starting filter pack, a

filter pack of 80M + 110Y is a reasonable starting point.

LATENT-IMAGE KEEPING

You should not notice shifts in the latent image with keeping

times from 1 minute to 24 hours. Therefore, you do not need

to change your printing procedures to compensate for

latent-image shifts under normal temperature and handling

conditions. (If shifts do occur, you can minimize their effect

by keeping the time between exposure and processing the

same for all paper.)

IMAGE HUE

The term “hue” usually doesn’t apply to untoned

black-and-white papers. However, this paper can exhibit

slight variations in hue because it uses colored dyes to form

images. When we use the term “hue” in this publication, we

are referring to the image tone (or image-tone neutrality) of

prints. We will use hue interchangeably with image tone to

describe images that vary slightly from neutral.

Those who view prints on this paper expect them to appear

neutral. Therefore, viewers are more sensitive to hue

variations in prints on EKTAMAX RA Paper than they are

to hue variations in color prints.

The most likely contributor to hue variations is the color

quality of the viewing light. However, improper storage

conditions and some processing problems can also cause

variations in hue. (The references to hue in the following

sections are based on tests made in the school-finishing and

commercial markets.)
