The Nareit logo is supplied in two different formats on the Brand Center: JPEGs and Adobe Illustrator EPSs.
JPEGs are raster files and the Adobe Illustrator EPSs are vector versions of our logo. Raster files create images with small dots (pixels) arranged in rows and columns. Vector files (also know as line art) use mathematical descriptions that determine the position, length and direction in which lines are drawn.
The quality of images in raster files is determined by the total number of pixels (the resolution). This resolution is expressed in terms of “dots per inch” or “dpi.” Images in raster files cannot be scaled to a larger size without loss of quality. The images in vector files can be used at any size with no loss of quality.
Software programs that enable you to create and manipulate raster files are called paint programs (such as Adobe Photoshop or Microsoft Paint). Programs that manipulate vector files are called draw programs (such as Adobe Illustrator or CorelDRAW).
In addition to JPEGs, there are many raster file formats, including GIF, BMP and TIFF. An EPS can be either a raster or a vector image, depending on the software that generated it. The EPS files on the Brand Center (generated by Adobe Illustrator) are vector images
