Great you got a great new logo designed, perhaps at my favorite logo crowdsourcing site 99designs.com, or by another graphic artist – now what?
Here is a checklist of the file type formats (.eps, .psd, .ai) and the sizes you need to get from your logo designers when you accept them as the winner of the logo contest. 99designs requires all their graphic artists to follow these guidelines for file downloads and gives them templates in the correct size and file formats
Logo File Formats with Explanations
|.ai - Adobe Illustrator (also called the original and editable file or source file)||To adjust and change the logo in the future|
|.eps Vector file in digital RGB (red, green, blue) format||For digital media|
|.eps Vector file in print (CMYK - cyan, magenta, yellow, black)||For print media and printing|
|.png, .jpeg or .jpg, .pdf Wed preview file||To view online and use for websites, social media and internet advertising|
Most images files for logos and business uses are generally divided into two categories, raster, and vector. Vector files are used mostly for digital purposes and rast2r for print, however, there is crossover and exception. Read on for more information about file types and how they will affect how your new logo will appear on your website, t-shirts and business cards.
Raster Images File Types
- JPEG or JPG
These Raster images are created by a grid of dots (pixels). Each pixel is assigned a specific color. Unlike vector images, raster images are created in one size and are not meant to be enlarged and made larger.
If you attempt to enlarge a raster image, you stretch the pixels, which can result in a “pixelated” or blurry image – sort of like the holes in swiss cheese. When you try to make a raster image larger, your graphic software will fill in, by guessing, the colors that are missing based on the surrounding pixels.
Graphic artists use raster image files for photo, digital art and web graphics (such as banner ads, social media images, and email marketing pictures.
CMYK vs. RGB
Raster logo images can be saved in one of two main color models: CMYK (for print) and RGB (for digital)
Vector images are math equations, where each dot, line, and shape is represented by its own mathematical formula.
Every “formula” can be assigned a specific color, stroke or thickness to turn the shapes into art. The superiority of vector images is that they are not sized dependent on the original image. You will not lose detail or get a blurry image when you decrease or enlarge your logo vector image.
Vector images are generally used for logos, icons, typesetting and digital illustrations.
