Configuring printheads

You can configure the number of jets and the number of ink drops to print per dot. You can also configure the relative starting position of the printhead, for example, to compensate for gaps between the printheads.

If all printheads have the same characteristics, you only need to configure one printhead.

The printhead definition must have a unique ID. You use the ID to assign printhead characteristics to a RIP, see Using a RIP with single printhead and Example 31.

To configure printheads

1	Configure a unique printhead definition ID with the printhead property.

2	If required, change the relative starting position for the printhead with the xposition property.

3	Configure the number of:

–	Jets with the jetcount property.

–	Drops per dot with the dropcount property.

Example 30

Printhead configuration

In this example, the printhead uses 2688 jets and prints 1 drop of ink per dot. The position of the printhead is not specified in the job file since xposition is 0.
