In the days of keyline and pasteboard production, I did tissue comps of designs which then were interpreted by a person who did typesetting galleys. They were not always as I have envisioned the type, but this was before desktop publishing so you could not see it on screen before the galley was photographically developed.
Our magazine did not have a budget for a staff photographer or models. We relied heavily on marketing materials provided by advertisers that might be preprinted samples. This added a creative challenge to bring something fresh to a layout when there was no control over the orientation of the images provided.
Design Challenge: This article is a two page spread where one page fell on a 4 color printed form and one on a black & white printed form. I had to come up with a design that made sense and appeared cohesive, so I used a border to unify the pages and the photos provided. I was able to show the contrast bewtween the past (black & white) and the present (full color).
The design challenge here was that the spread landed in the magazine where one page was printed on a B&W signature and one was printed on a color signature.
