Ryana,
Perhaps you would find it rewarding to to go back, and to look up
historical designs from the
period in graphic design history generally labeled as
"International style," and the works from the Swiss schools under the
tutelage of designers such as
Armin Hofmann, Emil Ruder, and others. Start with schools from Basel
and Weimar.
Then study Jan Tschichold.
There were a lot of printed works these practitioners, including
company bills and bills of lading and
the forms that companies run on (_ran_ on, anyway).
