Just as subprocesses should be placed at separate pages (diagrams), each process should be placed at a separate diagram when modeling collaboration. Communcating processes should be depicted as black boxes.
If processes are connected by several message and/or data flows, they should be identified by names. Make sure that the same messages have the same labels.
Although BPMN spec allows dataflows connected to black box pools (how to, diagram below), not all BPMN modelers support this.

It may be handy to depict several expanded processes on a single diagram for training/explanatory purposes but working models should follow the rule “one diagram - one process”.

Diagram should fit one page
