Create your poster to actual size. Use Page Set-Up 42"(wide) X 36"(tall) (42" X 36"). This way you can view your file at actual size (100%) to verify resolution and quality.
Overly complex posters created in PowerPoint can have display and printing issues. You will have less problems if you use fewer layers and keep your design simple. Adobe Illustrator is recommended for more complex designs, but note that Adobe Illustrator is not available in our computer labs.
Try to use only system fonts. Arial and Times New Roman are reliable fonts.
Make sure that any bitmap (pixel based) images contained in your file are scanned to a high enough resolution (150 ppi at final size). Resolution higher than 150 ppi will result in excessive file sizes.
Do not use the transparent or semi transparent setting in the fill options window.
Do not fill objects like graph bars with patterns. If you must fill graphs with patterns, please do so outside of PowerPoint and insert the graph as an image.
If you have a presentation that contains multiple slides, you will need to consolidate the slides into one slide of size 42"(wide) X 36"(tall). Examples of consolidated poster formatted presentations are below.
