For my job at the Lipscomb Communications Dept, I was tasked with creating a safety sign template for the science department laboratories that matched with the school's branding and that they could change and print as their needs evolved. I created a 3-piece sign with a clear acrylic frame and 2 interactive pdfs so the department could print out any sign they needed.
