Artwork and photos used in your poster should be original work. If you use material that is not yours, make sure you have permission to use the material before submitting your file for printing, and that your poster includes appropriate acknowledgement.
The image resolution for all artwork and photos should be at least 100 pixels per inch (ppi) after it is placed and sized in your poster file. If the image resolution is less than 100 ppi, the artwork and photos will appear pixelated or blurry when printed. For example:
- A 4"x6" photo that is 300 ppi can be enlarged 300% to become a 12"x18" photo at 100
- A 4"x6", 100 ppi photo that is enlarged 300% will become a 12"x18" photo that is only 33 ppi. This image will appear very jagged.
Test image quality by setting the zoom to 100% and checking the clarity of all images and photos.
