Engine print balancing procedure

Use this procedure daily to match the appearance of the solid black areas and the gray areas between the two printers. See Balancing print contrast between Printer 1 and Printer 2 and Balancing print boldness between Printer 1 and Printer 2.

Note:
You should perform this procedure sequentially.

Balancing print contrast between Printer 1 and Printer 2

To balance the print contrast between Printer 1 and Printer 2, do the following:

  1. Run a Primary Print Sample quantity of 500 to stabilize the print quality.
  2. Run the Alternate Print Sample to compare the front and back sides of the forms.

    Note:
    This Alternate Print Sample is only for high resolution printers. Low resolution printers use a different Alternate Print Sample.
  3. If the print contrast between Printer 1 and Printer 2 is not balanced, do the following:
    1. Starting with a lower contrast value, increase the value until the large black square on the Alternate Print Samples just fills in with solid black on one of the printers.
    2. Repeat step 3a for the other printer. Compare the samples marked 85 LPI.
    3. Use the contrast control (Printer Definition -> Print Quality) as necessary to make the black squares of equal darkness on both printers. This may result in different contrast values for each printer.
      Note:
      The contrast values change only for the loaded Snapshot.

Balancing print boldness between Printer 1 and Printer 2

To balance the PQE boldness between Printer 1 and Printer 2, do the following:

  1. Run the Alternate Print Sample at 50% boldness to compare the front and back sides of the forms.
  2. If the PQE boldness between Printer 1 and Printer 2 is not balanced, do the following:
    1. Select Printer Definition -> Print Quality.
    2. Adjust the PQE boldness of the printer with the lighter print to match the appearance of the 85 LPI grayscale of the darker print.

      Compare the grayscale appearance of both printers by folding one grayscale sample next to the grayscale sample of the other printer.

    3. Select OK to save the PQE boldness values in the printer configuration.
      Note:
      The PQE boldness values change only for the loaded Snapshot.
