X-Rite 882 Operation Manual

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.

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

These numbers are changes (indicated by the Greek letter

for exposing this internegative.

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.

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. 1A cut 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.
