Hi layla,
Draw your title block on the master layout using the normal 2d text, lines, fills and external drawings or images. It is generally recommended to place all items on the 'ArchiCAD Layer' to prevent them being turned off accidentally.
You can add autotext to any of these blocks of text which reads the contents of the 'Project Info' settings listing all the common information that could appear, like the project name, the address, the architect etc. This is all detailed in the help files.
These will then appear automatically filled out on all the layouts the master is assigned to, ensuring consistency.
When setting up a master I also find it best to set the paper size and margins by selecting the 'import settings from printer'. You can then guarantee that what you place on the master will print.
