CURRENT INFORMATION SUMMARY
Printer Conversion to
KODAK EKTACOLOR Edge 8 and
EKTACOLOR ROYAL VIII Papers
KODAK EKTACOLOR Edge 8 and ROYAL VIII Papers
incorporate new image-forming components to deliver
improved colors. These new papers are designed so that a
visually neutral patch will result in approximately balanced
red, green, and blue densities when measured with
densitometers that conform to ANSI Status A responses.
Some densitometers that do not conform to ANSI Status A
responses may produce non-matched red, green, and blue
densities for a neutral patch on these new papers. Labs that
use these non-Status A densitometers must compensate for
the differences in densitometer performance when they set
up printers for the new papers.
WHY DOES THIS HAPPEN?
Densitometers fall into two classes: (1) for analytical use and
(2) for comparative use.
Analytical densitometers conform to an ANSI standard
called “Status A.” Status A densitometers correlate colors
similarly to the human eye through a wide color and density
range. These densitometers will give similar readings for
KODAK EKTACOLOR Edge 7/ROYAL VII and
EKTACOLOR Edge 8/ROYAL VIII Papers if the prints
appear visually matched.
Comparative densitometers are designed to match prints
to a specific density. They are not intended for use over a
wide range of densities and colors, and they do not see colors
as the human eye does. These densitometers are often used
in printing systems as a part of a minilab or a high-speed
printer. They produce consistent measurements in the ranges
used for printer setup. However, with KODAK
EKTACOLOR Edge 8 or ROYAL VIII Paper, they do not
measure the neutral aim patches as neutral. For example, an
aim print on EKTACOLOR Edge 8/ROYAL VIII Paper
measures 0.80 red, 0.80 green, and 0.80 blue with a Status A
densitometer. The same print may measure 0.70 red,
0.80þgreen, and 0.80 blue with a comparative densitometer.
WHAT DOES THIS MEAN FOR LABS?
New EKTACOLOR Edge 8 and ROYAL VIII Papers
provide many performance advantages. But when they are
used with densitometers that do not conform to Status A
specifications, results may vary. Labs that use these
non-Status A densitometers must compensate for differences
in densitometer performance when setting up their printers
for the new papers.
When you are ready to convert to KODAK
EKTACOLOR Edge 8 or ROYAL VIII Paper, follow the
procedure below to determine how your densitometer
performs. Once you’ve determined the densitometer
performance, choose the appropriate compensation
procedure (if one is necessary).
To Determine If Compensation Is Required
1. Print your “Normal” Printer Control Negative on
EKTACOLOR Edge 7 or ROYAL VII Paper at the aim
density.
2. With EKTACOLOR Edge 8 or ROYAL VIII Paper,
balance to match the density readings from Step 1.
3. Compare the two prints. If the prints match visually,
follow normal printer paper conversion procedures (see
your printer manual). If the print from Step 2 appears
cyan, the densitometer is reading EKTACOLOR Edge 8
or ROYAL VIII Paper differently. You will need to
follow one of the compensation procedures below.
Note: Compensation procedures have not been prepared
for equipment that produces matched prints in Step 3 of
the procedure above. If your printer is not included in
the list below, follow your equipment manufacturer’s
paper setup instructions.
