Logo Signature File Types
When downloading UWF logo signature files, multiple file formats of each signature will be included. Each format has features and limitations that make them suited to specific uses or distribution channels. The following definitions briefly describe the basic differences between each format and their appropriate uses.
Vector Files (.eps)
Use: Printing (flyers, brochures, banners, promotional items)
A vector image is created using mathematical descriptions of points, lines, and curves. Vectors can be scaled to any size without loss of clarity. Vector file formats are used in graphics software such as Adobe Illustrator. Vector files are the best format to use when professionally printing materials.
Raster Files (.png)
Use: Electronic Distribution, Limited Printing (web pages, newsletters, Powerpoint presentations, Word templates)
A raster image is made up of small, individual colored squares called pixels. When enlarged, raster files can become blurry or “pixelated.” Be sure to use properly sized raster files rather than scaling images that are too big or small. The backgrounds of .png versions of the UWF logo signatures are transparent.
PDF Files (.pdf)
Use: Printing, Downloads, Attachments
Adobe’s PDF file format is the best of both worlds—good for both digital sharing and print distribution. PDFs may contain raster images, vector images or a combination of both. They work well for downloadable files as they can be opened with most modern web browsers and PDF readers on many different devices. The PDF versions of the UWF logos and signatures contain vector graphics that can be used by professional printers.
Spot vs. Process
Each set of logo signatures is provided in the approved colors in two categories referred to as spot and process colors. Spot colors are very specific, pre-mixed inks that are part of a system called the Pantone Matching System. These colors are highly standardized and will therefore reproduce the same way each time they are used. Spot colors are usually required for producing promotional items such as t-shirts, cups, bags and other screen printed items. However, unless your vendor requires spot color, it is not cost effective for general printing. Beyond that, a general printed piece would need to meet a quantity threshold to qualify for the style of printing required to use spot colors.
Most UWF print projects utilize process colors. Process colors are created by blending four colors together — cyan, magenta, yellow and black. These four colors combine during the printing process to create every color included in a print project. If you are unsure of which color type to use, your vendor should be able to advise.
