Creating Graphics for Event Displays – Tip #4: Fixing Resolution Issues

We hope that you had a chance to read  Tip #1 and Tip #2 and Tip #3  about submitting graphics for event displays. Read below for Tip #4 about how to detect issues with image resolution and submit your artwork in way that will obtain the best results.

Tip #4: Fixing Resolution Issues

At Expand, we like to help you get your job completed quickly and efficiently. Often times, jobs are held up due to image quality concerns. Below are some guidelines to avoid issues with image quality when submitting artwork to our graphics department.

Submit images with a DPI from 125 to 150:  

Images should fall between 125 to 150 DPI (dots per inch) at final print size. Higher DPI can result in a larger file size without any gain in image quality, while a lower dpi can result in diminished image quality and extremely noticeable pixilation.

Below is an example of the difference between an image with very low DPI vs. one with a proper DPI of 150:

Actual Image Dimensions: 40″ x 26″ @ 72 DPI: The Image is very pixilated and is not the recommend DPI for Large Format Printing.
Actual Image Dimensions: 40″ x 26″ @ 150 DPI: The image is clear and is the recommended DPI for Large Format Printing.

Never rez up an image: 

We do not recommend “rezzing up” an image. Increasing the DPI on a file will create false pixels and ultimately compromise your image quality.  As we mentioned in Tip #1 , you want to create graphics that can be seen from up to 10 feet away. It’s important that the image is clear and will not look fuzzy or pixilated from that viewing distance.

We cannot print from PSB (Photoshop big) files and therefore do not recommend artwork to be submitted in that format. Large Photoshop files can be flattened and saved as a TIFF with LZW compression. This will reduce file size without sacrificing image quality.

View your file at full size: 

Make sure to view your file at the final printing size in order to detect problems with image quality early on. Size and resolution are dependent upon each other when dealing with raster images.
