About Printing Tracings and Blocks
It is important that tracings and blocks are printed at the correct size so that they will ‘fit’ the corresponding chart. To ensure correct fit, mariners should refer to the instructions contained within About Australian Notices to Mariners (AHP18).
Please note that blocks are now only available within the full edition.
