Kodak CIS-201 Compensation Procedure for, NORITSU 1401/1501 Printers, Densitometer Method

For other printers, follow these steps:

1.Print your “Normal” Printer Control Negative on EKTACOLOR Edge 8/ROYAL VIII Paper again at the aim density, and with 1 red, 2 red, 3 red, and 4 red color-correction buttons.

2.Compare these prints to the print from Step 1 under “To Determine If Compensation Is Required” (EKTACOLOR Edge 7 or ROYAL VII Paper printed on aim). Determine which red-corrected print is the closest match. The amount of red correction used to make that print is the amount required to compensate for the difference in densitometer measurement. Add the red correction to your paper channel setup for EKTACOLOR Edge 8 or ROYAL VIII Paper.

3.Print the “Normal” Printer Control Negative on the new paper again (the print should appear neutral), and measure this print. Record these density readings as your aim densities. Write the aim densities on this print, and keep it to use as your aim.

4.Adjust your paper Under and Over slopes to match your aim.

5.Print some customer negatives on this setup and adjust for preferences if necessary.

Compensation Procedure for

NORITSU 1401/1501 Printers

Follow this procedure to convert to KODAK EKTACOLOR Edgeþ8/ROYAL VIII Paper from KODAK EKTACOLOR Edge 7/ROYAL VII Paper. This procedure permits conversion without the use of the printer’s built-in densitometer. It includes a choice of methods: an external densitometer method and a ringaround method.

Densitometer Method

For this method, you must use an X-Rite or similar densitometer that has Status A filters (e.g., an X-Rite 881 or 891 densitometer) to measure the print densities.

1.When your supply of EKTACOLOR Edge 7/ ROYAL VII Paper is about to run out, print the Printer Setup Negative “Normal,” “Under,” and “Over” on the channel most commonly used for the paper. Label the three prints “Old-Paper Reference Print—Normal,” “Old-Paper Reference Print—Under,” and “Old-Paper Reference Print—Over.”

Keep the negative and prints in a safe place. Record the paper channel and Morning Setup channel used to print this test.

Also record the channels that will be using the new paper. Only these channels will be corrected.

Note: If this paper size/surface will also be used for Morning Setup, you must include channel 00 in the corrections.

2.When you are ready to convert to the new paper, load it into the printer.

3.Print the “Normal” Printer Setup Negative on the new paper, making sure to use the same channel as in Step 1. Label the print “New-Paper Test Print.”

4.Use the external densitometer to measure the Old-Paper Reference Prints and the New-Paper Test Print, and record the readings. See the example.

Example

Densitometer Readings—Normal Reference

and Normal Test Prints

	Cyan	Magenta	Yellow
REFERENCE	75	80	73
TEST	90	87	73
Difference	-15	-7	0

Note: To obtain the difference, subtract the test-print density from the reference-print density.

Add the Cyan + Magenta + Yellow difference values to obtain an overall density reading. Then divide by 50 to obtain the density correction:

Density

Correction

Difference -15 -7 0 = -22 -22 / 5 = -0.4

Divide the Cyan, Magenta, and Yellow difference values by 10 to obtain the color correction:

Color Correction -1.5 -0.7 0.0

The correction for this example is -1.5 Cyan, -0.7 Magenta, 0.0 Yellow, and -0.4 Density.

5.Identify which channels are currently using Edge 7/ ROYAL VII Paper. These channels will all require the same correction.

Note: If the Master Balance or Morning Setup channel will use the new paper, you must include CH 00 in the Channel Balance Shift.

6.Apply the balance correction to the paper channels using this paper size:

MODE 33 (CH SHIFT)→ YES→ CH BALANCE SHIFT→ D-IN→YES

7.If you will use the new paper for channels 10, 11, 12, 13, 14, and 15, you would enter the following to input the corrections calculated in the example above:

10-15 (N)	Range of channels
	Input corrections
0.0Y -0.7M 1.5C -0.4D Y/N	calculated above.
	Press arrow keys to
	move cursor.

The Channel Balance correction will be made to channels 10, 11, 12, 13, 14, and 15.

Note: If the Master Balance or Morning Setup channel will use the new paper, you must include CH 00 in the Channel Balance Shift. For example, if channels 01, 02, 03, 04, 05, 06,and 07, and the Master Balance or
