Vector images are needed for various reasons in all media organizations, as they can be scaled without losing their quality. One of the most popular format that is currently being employed is the Encapsulated PostScript (EPS) file format.
Did You Know?
Personal computers supporting the EPS file format were first pitched by Apple founder Steve Jobs for their NeXT computers.
Vector graphics have been in use by air traffic controllers to guide planes on the landing strip. Now, they are used in almost all sorts of media for presentation purposes.
The fonts that we take for granted were mathematical curves or points using a pen plotter. The formats for creating these files were written in PostScript language.
It’s a page description language that includes metadata about the image, as well as security features that protect the image from corruption. This is mostly used in the desktop publishing industry. One of the image formats that was written in this language is the EPS file.
What is an EPS File Format?
EPS, or Encapsulated PostScript, is a PostScript document that has an image or bit map embedded within it. EPS files are used in all vector-based software, like GIMP, Inkscape, Adobe Illustrator, etc. These files provide information and comments about a particular image, as well as a preview in the current window.
EPS files also contain information that can be read by printers and typesetters. The EPS file formats were used by Adobe in the form of TIFF, that supported the header information, though most Windows-based PCs used the Windows Metafile format (WMF). Another file format that shows previews in black-and-white is the EPSI format, used on UNIX systems.
□ They are used to compress composite images or raw images clicked by a digital camera.
□ They are used by graphic designers to make designs that are print-ready.
□ These files are compatible on multiple platforms, and can be easily viewed on a PC or a Mac.
□ They are also used for printing graphics on T-shirts, since their typesetters support the EPS file.
□ The advantage of an EPS file is that, it can be scaled to any size and retain its quality without getting pixelated.
□ These files can be used to combine text and graphics together very easily.
□ They are recognized by printers, in which you can add additional information that will reflect the changes in the output.
□ They can easily be imported into other desktop publishing software, especially to edit logos and other designs.
□ They are easily supported by any word-processing software, like Microsoft Word.
□ Most operating systems don’t support multiple-page EPS files.
□ Saving work in an EPS format can take time.
□ EPS files should be print-ready, as many page layout software don’t support modification.
□ All EPS files must have a minimum resolution of 300 dpi (dots per inches), or they end up losing their quality.
EPS files are used by desktop publishing software embedded in their own format, like TIFF, WMF, etc. That being said, EPS is a dying format, that’s soon going to be replaced by the PDF.
