Our last post about vector art noted that an explanation of raster graphics was a story for another day and guess what. That day is here!
If you recall, vector graphics use mathematical equations to “draw” the image so there’s no loss of resolution as they’re sized up. That makes them great for logos and other simple graphics, but not so great when you need more detail. Raster graphics, in contrast, are made of countless tiny dots (sometimes called pixels) that when viewed as a whole create an image. The family photo on your desk is a raster image…and so is that selfie. Typical file types include jpg, png, tiff, bmp and gif.
The tiny dots that comprise a raster image are what makes them capable of displaying richly detailed images and highly editable. The more dots per inch (dpi) the more precise the detail. Plus you can actually edit every single one of those dots to get exactly the image and color you want. The possibilities are endless!
The downside? Well, when you enlarge a raster image you enlarge those dots (as well as the space between them) and can end up with a fuzzy image if you go too far. Plus, remembering the individual characteristics of every dot makes raster file sizes pretty big and sometimes unwieldy. If they’re too large they can slow down your computer and be difficult to transport.
It’s a cinch that you’ll use raster images for your print and marketing materials at some point, so let the experts at Curtis 1000 make sure they look precisely the way you want them to…down to the very last pixel. Call us at 877-287-8715 or fill out the “How Can We Help You” form on our website!
