Developing large format graphics may pose some new challenge for many graphic designers. For the most part trade show graphics require the same creative and layout skills and software’s, but there are differences related to resolution of images that need to enlarge to many times their original size.
Below are key factors that may be helpful to know going into large format graphic design for trade show graphics. If by chance these guidelines don’t provide what you need to know, give us a call, we will get you the proper answer so you can build your art files knowing they are correct for the size, and materials of your rental booth.
Most designers use Adobe Photoshop/Illustrator and some international designers use InDesign. The preferred method seems to be the use of Illustrator as the foundation where all text and shapes are created. Images are adjusted in Photoshop, then imported onto the Illustrator document and positioned and sized.
We can accept all Adobe files, but we prefer PDF’s as they avoid the issues of linked fonts or images.
Bleed Margin says that you are actually making your image slightly larger that the final size you need. Adding bleed is the same as saying adding a half inch extra border. The art will typically have guidelines or registration marks showing finished size. The bleed portion is there just in case a little extra is needed to sew into a seam, or tuck into a frame.
Ideally you would build your art files to be the full 100% print size. This assures the size of the final printed product is correct and the quality is as intended. Designers scale art primarily because large format graphic files become larger than their computer can handle. The solution is to build the art smaller with twice the resolution so the printer can enlarge the file to the proper size and resolution. When you need to do this, make sure your math is correct for both resolution and scale so that the result is a print ready art file, at the correct size, and with a minimum PPI of 150.
If you want a clear, detailed trade show graphic, then start with images that will hold their detail when enlarged to the size you need. Photoshop and other programs allow you to enlarge your image and view it as “Actual Size” to show you on your monitor how the image will look when you’re standing up-close looking at it in person.
When a high quality image loses its quality, it may get grainy or blurry. When a low quality image loses its quality, it starts to pixelate and small boxes become visible around the details and edges. Sometimes a small amount of distortion is acceptable, especially if you can’t get a better image. Start with a great image, be flexible and find a different image of better quality if your first choice is of poor quality. Shutterstock sells high quality images ready for download and most of these will work just fine for use in your booth graphics.
