Would anyone know how to explain simply how the method of printing is done
differently between the magazines and the newspapers? Thanks for any
advice.

The paper is much different. Glossy magazine paper
is filled with kaolin (a mineral) and casein (protein
from milk) as sizing and surface treatment. The printing
process is also much different, with many more steps
for a magazine page. For example, when there is both
a glossy and a dull surface texture on the same page,
that means they've done an extra pass to print a layer
of shellac. Magazine papers may also have odorant
additives. I would not use those papers for anything.
