Dynamic color registration is not saved in the substrate preset and so the printer remembers only the last dynamic color registration that you performed. You need to repeat it in any of the following cases: ● Whenever you change the type of substrate on which you are printing. ● Whenever you align the printheads. ● Whenever you change the drying temperature. NOTE: Substrate expansion or contraction does not occur immediately at the beginning of a print. You are unlikely to see it in the first 0.5 m (20 in) of printed substrate. After dynamic color registration, you may notice overcompensation in the first 0.5 m (20 in) of each job, depending on the substrate. Dynamic color registration without the test pattern You can, if you like, enter the A and B values without printing the test pattern. There are two scenarios in which you may want to do this. ● You have printed the test pattern for the same substrate in the past and already know the correct A and B values. The width of the substrate is irrelevant: you can use the same values for any width of the same substrate type. ● You intend to find the correct A and B values by trial and error. In this case, you need to know that the A value affects printing on the right-hand side of the substrate, while the B value affects printing on the left-hand side. Increasing the value moves magenta to the left, descreasing it moves magenta to the right. Dynamic color registration on the fly You can adjust the dynamic color registration while the printer is printing. In the HP Internal Print Server, select Printer > Printing adjustments. Printer calibration Change the A and/or B values and click Apply. The A value affects printing on the right-hand side of the substrate, while the B value affects printing on the left-hand side. Increasing the value moves magenta to the left, descreasing it moves magenta to the right. The new calibration will be visible after a certain length of substrate has been printed on. The length will depend on the print mode. Examples: ● With a 2-pass print mode, about 1 m (40 in) of substrate will be printed before the calibration takes effect. ● With a 4-pass print mode, about 0.5 m (20 in) of substrate will be printed before the calibration takes effect. ● With an 8-pass print mode, about 0.25 m (10 in) of substrate will be printed before the calibration takes effect.

Dynamic color registration is not saved in the substrate preset and so the printer remembers only the
last dynamic color registration that you performed. You need to repeat it in any of the following cases:
●
Whenever you change the type of substrate on which you are printing.
●
Whenever you align the printheads.
●
Whenever you change the drying temperature.
NOTE:
Substrate expansion or contraction does not occur immediately at the beginning of a print.
You are unlikely to see it in the first 0.5 m (20 in) of printed substrate. After dynamic color registration,
you may notice overcompensation in the first 0.5 m (20 in) of each job, depending on the substrate.
Dynamic color registration without the test pattern
You can, if you like, enter the A and B values without printing the test pattern. There are two
scenarios in which you may want to do this.
●
You have printed the test pattern for the same substrate in the past and already know the correct
A and B values. The width of the substrate is irrelevant: you can use the same values for any
width of the same substrate type.
●
You intend to find the correct A and B values by trial and error. In this case, you need to know
that the A value affects printing on the right-hand side of the substrate, while the B value affects
printing on the left-hand side. Increasing the value moves magenta to the left, descreasing it
moves magenta to the right.
Dynamic color registration on the fly
You can adjust the dynamic color registration while the printer is printing. In the HP Internal Print
Server, select
Printer
>
Printing adjustments
.
Change the A and/or B values and click
Apply
. The A value affects printing on the right-hand side of
the substrate, while the B value affects printing on the left-hand side. Increasing the value moves
magenta to the left, descreasing it moves magenta to the right.
The new calibration will be visible after a certain length of substrate has been printed on. The length
will depend on the print mode. Examples:
●
With a 2-pass print mode, about 1 m (40 in) of substrate will be printed before the calibration
takes effect.
●
With a 4-pass print mode, about 0.5 m (20 in) of substrate will be printed before the calibration
takes effect.
●
With an 8-pass print mode, about 0.25 m (10 in) of substrate will be printed before the calibration
takes effect.
