Technical Guidelines
The BSGA Technical Guidelines provide a definitive source of information on every aspect of signmaking and are an invaluable tool for every signmaker. The guides have been produced over a great many years and are constantly updated and upgraded by the Technical Committee and its advisors.
In this section we provide a synopsis of the contents. Full contents are available to members only and can be accessed, as downloadable PDFs, in the secure “members only” area of this site.
