Instructions
To co-brand web transition pages and printed materials, please submit your logo in a suitable format for the intended use.
The resolution, or the sharpness and clarity, will determine which file types are used for the web (low-resolution) or print (high-resolution).
To the ight you will find the necessary requirements for your logo. |

Logos for Web Transition Pages
|
| Acceptable logo types for transition pages only: |
JPEG (sized to a maximum of 150 x 100 pixels)
GIF (sized to a maximum of 150 x 100 pixels)
EPS (vector fil, preferred) |
| The display size of logo online will be: |
 |
| Horizontal vs. vertical orientation |
If a logo is extremely long, resizing it to fit the size above may render it small and difficult to read. Many partners have alternate versions of their logos for this purpose. For example, look at the logo below. The “vertical orientation” (also called "stacked") of the logo fills the space much better and looks bigger than the “horizontal orientation.”
 ––"vertical orientation"
 –– "horizontal orientation"

| Logos for Printed Materials (Brochures, Flyers, & Workshop Materials) |
| Acceptable logo type for printed materials: |
EPS (vector file preferred for professional printing)
In cases where an EPS logo is not available, please keep in mind that several factors will determine the quality of printing a JPEG (or TIFF) logo. First, the resolution (minimim of 300 DPI) is limited by the size. A small logo cannot be printed at a larger size, and the screen-size (what it looks like on a monitor) can be deceptive. Second, do not manipulate a small logo in a program like Photoshop to appear larger or increase the DPI. The result will be a very fuzzy logo. Basically, size is a one-way street: a large JPEG logo can be made smaller, but a smaller JPEG logo cannot be made larger. |
| Vector files (EPS) vs. Raster files (JPEG) |
A vector file, typically created in an illustration program like Adobe Illustrator, is made of clean lines which allows for easy resizing with no lost resolution. Raster files, typically created in Photoshop (or scanned), are made of pixels, and the resolution is limited. For example, look at the logo below. Zooming in on the "vector" logo shows a much clearer resolution.
 EPS "vector file"
 JPEG "raster file"

| Why EPS vector files preferred for professional printing |
Vector EPS files (which are typically created on programas like Adobe Illustrator) can be easily enlarged or reduced with no loss of resolution. EPS files are best for professional printing, and will result in crisp reproduction. Precise color matching or inverting the contrast is also possible when using EPS files. Also, most true vector EPS files have a transparent background (unlike JPEGs which typically have a "white box" background). |

Do's and Don'ts
-
Don't enlarge small JPEG logos in Photoshop. As a general rule of thumb, JPEG (raster) logos can only be reduced in size.
-
Don't manipulate the resolution in Photoshop. For example, a GIF taken from a website could be incorrectly enlarged in Photoshop to a higher resolution, but the result is a very blurry image.
-
Don't covert JPEG files to EPS files. The result is not a "true" EPS file. EPS files are typically created on Adobe Illustrator or similar illustration program.
-
Do send us "true" EPS vector files (created on Adobe Illustrator for example) which can be easily resized without compromising the resolution.
-
Don't open vector-based EPS files in Photoshop. This irreversibly converts the file to the less flexible raster format.
-
Do send EPS files when you need a transparent background. Unlike many other formats, EPS files allow for placement on PowerPoint and other applications without a "white box" behind them.
-
Don't send logos in PDF or Word formats. Logos embedded in other documents cannot be extracted.
