Using desktop publishing tools
CLCs can themselves produce their own consistent-looking publications (e.g. the annual report, research reports) using desktop publishing (page layout) software or commonly-available word-processing software such as Microsoft Word.
To take full advantage of such software, a staff member should undertake training in its use. Local community or evening colleges often have short courses.
Of course, CLCs with a sufficient budget may want to use a graphic designer but you still need to manage that process tightly.
