logo design - description of bitmap and vector file formats

HOME CONTACT

Successful logo must be applicable both in black and white and in color, in multiple sizes and it must translate well in all modes of communication.
There are two major graphic types: bitmap and vector file formats. At info@ehzd.com both of these file formats are included in each of our logo design packages.
A bitmap file (for example .gif or .jpg) is an image made of dots (pixels). Each dot contains different color information. It depends on the resolution (dpi - dots per inch), how many dots are there in an image. The higher the resolution, the better the quality of the image. Scaling a bitmap file causes loss in quality. Therefore it should be used only at the same size it was created.
A vector file (for example Illustrator .eps) is an image both scalable and fully editable, designed to be scaled and resized without any loss in quality.

Print logos are usually saved in EPS or TIFF format.
Web logos are usually saved in GIF or JPEG format.

Your final logo design will be saved and sent to you in the following formats:

.gif and .jpeg files (72 dpi, 216 index color). This is your logo suitable for web applications. These files are optimized in web-safe colors for rapid downloads on the web. They will have true color accuracy on all platforms and browsers.

- .jpeg file (300 dpi). This is your logo in high-resolution mode, which can be converted and imported into most desktop publishing and word processing software. This file can be resized (down) and used in monitor friendly (RGB) or print friendly (CMYK) color modes.

- .tiff file (300 dpi). This is your logo in high resolution (bitmap) mode for traditional printing.

- .eps file (300 dpi). This is your logo in Encapsulated Postscript format, required for traditional printing. It is both scalable (can be resized without any loss in quality) and editable. Most commercial printers and software packages can use it.

- onetone .eps file (300 dpi). This is your logo in black and white suitable for faxes, invoices and other media, which does not require high quality reproduction. In some countries you will need a black-and-white version of your logo for its registration.
