All of my design based from vector(Ai,PSD, and EPS).And i draw it (this designs) by myself.
AI: Adobe Illustrator vector format with editable text - will allow your logo to be scaled up and down as needed, you can also
change the tagline or the color scheme.
PSD: Fully scalable built with vector masks, Photoshop layered file. The PSD file format is an industry standard and it allows color
changes, or even adding or removing parts of the logo (by hiding or activating layers). The normal desktop printers (ink-jet and
colour photocopier) are designed to work happily with a range of image file formats, including JPEG compressed files. However they
will still work best with the maximum amount of image data supplied by an uncompressed image such as a PSD file.
EPS: This is an industry standard, meaning "Encapsulated PostScript". It can be imported into all major design programs, and is often
the file of choice for printing companies.
