I was looking through my Letraset and Mecanorma catalogs and wondering what the process was like for font submissions 40-50 years ago. Many of the new additions in each catalog were from established designers and non-exclusive, but some designs were submitted by young "indie" designers and perhaps students. Does anyone know what the process was like? Were designers involved in producing the final layout for the dry transfer sheets? Did each designer set sidebearings in order to set the spacing guides (dashes under the characters) that were included on the sheets?
