When creating or sending assets, avoid screenshots, or photos of a photo.
If content looks pixelated to begin with, it’s still going to look pixelated on your sign. It works best to scale down to fit content, as opposed to scaling up. Luckily, if your team utilizes vector graphics for their logos and other assets, you won’t have to worry about size affecting quality.
Vector files (.svg, .eps, and .ai, to name a few) utilize points, lines, and curves based on mathematical equations. So, no matter how big or small the image is, it will appear the same.
Keep in mind that photographs and many file formats are not vector files, so assets that are .jpeg, .png, and some .pdf formats should still be created with the highest quality in mind.
