CURRENT INFORMATION SUMMARY  
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.  
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.  
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.  
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.)  
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.  
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.)  
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

Procedure to Confirm Leuco Cyan Dye. If you suspect  
that leuco cyan dye is the cause of a red image tone, you can  
bleach a processed print in FLEXICOLOR Bleach III  
Replenisher to confirm a leuco cyan dye condition. Follow  
this procedure:  
due to inefficient squeegees in the developer or low  
bleach-fix replenishment. Any condition that allows the pH  
of the bleach-fix to increase can produce a slightly pink  
image tone.  
These conditions are not generally reflected in the control  
plots, but you can correct them by reducing the pH of the  
bleach-fix. Add KODAK EKTACOLOR RA Bleach-Fix  
and Replenisher NR, Part C, or glacial acetic acid (see the  
following table).  
1. Choose a print with a neutral density between 1.20 and  
2.00 (1.60 to 1.80 is best). Take density readings of  
specific areas on the print and mark the spots so that you  
can take comparison readings after bleaching the print.  
2. Immerse the print in FLEXICOLOR Bleach III  
Replenisher solution at 21°C (70°F) for 2 minutes.  
3. Rinse the print for 1 minute in running water at 21 to  
43.3°C (70 to 110°F).  
Caution  
4. After rinsing the print, run it through the last wash and  
the dryer of the same processor used to process the print  
the first time. It is important to achieve the same surface  
gloss, because the gloss will affect the density reading.  
Before making changes to the bleach-fix, verify that the pink  
hue is not caused by a developer activity problem. Check  
your developer replenishment rate, processor utilization,  
and control plots. Overuse of the following prescription will  
cause leuco cyan dye problems. Be sure to very that the pink  
hue is not developer-related before applying this  
prescription.  
After bleaching, washing, and drying, read the red and  
green densities in the areas you marked. Subtract the original  
red and green densities of the print from the red and green  
density readings of the print after bleaching. Then subtract  
the green density difference from the red density difference.  
If the answer is greater than 0.10, leuco cyan dye is  
confirmed.

Add the appropriate amount of EKTACOLOR RA  
Bleach-Fix and Replenisher NR, Part C, or glacial acetic  
acid to the bleach-fix tank. Allow the solution to mix  
thoroughly, and then process some test prints. If the pink  
cast is reduced but not eliminated, repeat the prescription  
once. If the pink cast does not change, do not repeat the  
prescription. If a pink hue remains after you apply the  
prescription a second time, it is likely that your process has  
a developer problem or that your viewing conditions are  
inadequate (recheck that you are using the appropriate light  
source).  
Because the red density difference minus the green  
density difference is greater than 0.10 (0.15 – 0.04 = 0.11),  
the test confirms that leuco cyan dye is the problem.  
Correcting Process Problems  
Follow the appropriate procedure below to correct the  
process problem identified in the preceding section.  
High developer activity  
High activity may be due to a high replenishment rate, a high  
temperature, or bleach-fix contamination of the developer.  
When you have identified the cause of the condition, make  
adjustments to correct it.  
Low developer activity  
Low activity may be due to low processor utilization, a low  
replenishment rate, or high oxidation. You can notice this  
condition in your control plots. In addition to having a  
slightly pink hue, prints on EKTAMAX RA Paper will have  
a “muddy” upper scale. When you have identified the cause  
of the condition, make adjustments to correct it.

Note: When you add developer starter to the bleach-fix,  
foaming will occur. Turn off the bleach-fix recirculation  
system and add the starter very slowly. Wait several minutes  
for any foaming to dissipate before turning the recirculation  
pumps on. You may want to consider removing some  
bleach-fix from your working tank and adding the starter to  
that solution to avoid any chance of the bleach-fix foaming  
over and contaminating your developer tank. Slowly stir the
