X-Rite®882
(An Addendum to the X-Rite 881 Operation Manual)
The X-Rite 882 was designed to meet the quality control needs of the professional
photofinisher processing E-6, as well as the other common processes.
The 882 is very much like the X-Rite 881, except that the 881 has only Status M for
transmission operation, and the 882 has Status A and M for transmission operation.
Transmission Status A is used for checking Positive transparencies (i.e., E-6 films) and
Status M for checking Negative transparencies (i.e., C41 negatives). The 881 Operation
Manual explains all of the functions and operation of the 882. However, there are a few
differences in operation and they are explained in this 882 addendum.
The 882 has the additional capability of:
•Measuring E-6 (Kodak & Fuji), Q-Lab, AP44, and P-5 film strips
•Measuring 2 different types of Internegatives
The additional film strips are selected and measured in the same manner as the other
film strips explained in the 881 Operation Manual. The procedure for selecting and
measuring internegative strips is explained in Section 1 of this addendum. Refer to
Section 2 for definition on the additional film strips and internegatives.

1. Measuring an Internegative
The 882 allows measurements of internegatives. It will optional compute the changes in exposure
and filter pack necessary to balance the internegative using the Density Difference method.
Step 1 - Press [film].
Step 2 - Press [other] until "Ineg Step 1"is
displayed.
Step 3 - Select the interneg type (see Section 2
for type definition).
Each depression of the [type] key will
alternate between "type 1"and "type 2"
(for this example "type 2" is selected).
Step 4 - Select interneg film type.
Press either center key to select the film
type. Select "6011" if you are using film
similar to Kodak 6011 or 4112 Interneg
film. Select "4114" if you are using film
similar to Kodak 4114.
Step 5 - Insert strip into the 35mm slot (step 1
inserted first) until it rests against the
drive rollers.

Step 6 - When the reading is completed, the
display will indicate which step pair will be
used on subsequent calculations.
•Pressing the [view] key allows viewing
of density difference numbers (refer to
Section 1.1).
•Pressing the [+Step-] key allows
viewing of the individual steps on the
strip (refer to Section 1.2)
•Pressing the [auto] key performs filter
pack and exposure calculations
automatically (refer to Section 1.3).
›If the strip is severely over exposed, the warning message
"STRIP TOO FAR OVEREXPOSED" will appear briefly. You will
then be allowed to view the individual steps using [+]or [-]
step keys, but will not be able to use the view and auto
functions. If this happens, reduce your exposure by three or
four stops and try another strip.
1.1 View (continued from Step 5 in Section 1)
The View function allows you to view the density difference values and recommended
filter pack changes. Density difference values are calculated by simply subtracting the
density values of the higher numbered step from the densities of the lower numbered
step. These are used to look up your filter pack changes from the table.
Step 6 - Press [∆fp] key to get the filter pack
changes from the internal table and
display them.
›These numbers are changes (indicated by the Greek letter
∆) and should be added to the filter pack which was used
for exposing this internegative.
Step 7 - Press [∆den] key to display the density
difference values again.
Step 8 - Press [exit] to return to the Step Pair
Menu so that further viewing or
calculations can be performed.

1.2 +Step- (continued from Step 5 in Section 1)
The +Step- function allows viewing of the individual steps on the strip.
Step 6 - Press either the [+]or [-] key to view
data on each step of the internegative.
•[+] increments to the next step (step 21 will
advance to step 1).
•[-] decrements to the next step (step 1 will
advance to step 21).
Step 7 - Press [exit] to return to the Step Pair
Menu so that further viewing or
calculations can be performed.
›For "Type 1" internegatives (4 x 5 format), all of the even
numbered steps are computed internally using a curve
fitting algorithm because the actual internegative contains
only the odd numbered steps.
1.3 Auto (continued from Step 5 Section 1)
The Auto function initiates the automatic
exposure and filter pack compensation.
Step 6 - "Enter Starting Filter Pack..."is
momentarily displayed. Enter the values
of the filter pack used to make this
internegative.
•[↑] increases the value marked by cursor.
•[↓] decreases the value marked by cursor.
•[→] moves the cursor to the next position.
Press [cont] when finished.
Step 7 - "Enter Exposure"is momentarily
displayed. Enter your exposure time and
aperture.
›The "f" stop values increase or decrease in 1/6 stop steps
and values can range from f/4.0 to f/32.0.
•[↑] increases the value marked by cursor.
•[↓] decreases the value marked by cursor.
•[→] moves the cursor to the next position.
Press [cont] when finished.

Step 8 - The display now indicates suggested
changes to your filter pack.
›The numbers displayed are changes (indicated by "∆")
and should be added to the filter pack which was used to
expose this internegative.
Press [∆off] to turn the "change mode"
off and view "absolute" filter pack values.
Absolute values are the addition of your
starting filter pack (entered earlier) to
the changed values.
›These values are adjusted to remove any neutral density.
Therefore, one of these values (usually cyan) will always
be zero. These values constitute your new filter pack
which should be used for subsequent exposures.
Step 9 - Press [exp] to display the suggested
exposure.
›Any neutral density adjustments to the filter pack will
affect exposure as well. To avoid reciprocity problems,
exposure time is held within 1/2 stop of your starting
exposure time. This will sometimes cause an aperture
change if the calculated exposure time adjustment is
greater than 1/2 stop.
Step 10 - Press the [read] key to measure another
internegative. The entire procedure
described is repeated except that the
exposure and filter pack values you have
just viewed will be used as the starting
values.
Step 11 - Press the two keys labeled "MENU"to
exit out of the interneg function.
›Since internegatives are a setup tool rather than a process
control tool, any internegatives read are not stored in
channel memory. Data that is currently stored in the
channel memory is not destroyed.

2.2 Internegative Film Strips
•Type 1 (4 x 5)
The "Type 1" interneg consists of a
Kodak Step Tablet No. 1Acut between
steps 11 and 13, with the two halves
mounted side by side in a slide frame (see
illustration). Make sure that the full
length of the steps 11 and 13 show (i.e.,
not covered by the inside edge of the slide
frame).
This slide is then projected on to a 4 x 5
interneg such that each step is 1/2" wide.
Step 11 and 13 should begin
approximately 1/4" in from the edge of the
interneg. Note: Steps 1 and 21 can go off
the other end during projection - this is
OK.

•Type 2 (35mm)
The Type 2 interneg consists of a Kodak
Step Tablet No. 3 contact printed onto
35mm internegative film. To enable the
resulting interneg to be recognized by the
882, a piece of opaque tape must be
placed over part of step 1 on the step
tablet as shown. The tape should be
placed such that 0.4" (approx. 3/8") of step
1 is still exposed adjacent to step 2.
To satisfy the leader requirements of the
882, a 1-1/8" leader should precede the
taped area on the resulting interneg.
This strip is inserted into the 35mm slot
with step 1 entering first.
