What is illustrator

a program for illustrating and vector graphics

Adobe Illustrator is a program used by both artists and graphic designers to create vector images. These images will then be used for company logos, promotional uses or even personal work, both in print and digital form

Bleed is the part of the image or background colour that runs off the edge of the printing area of a document before the document is trimmed down to size. The purpose of the bleed is so that there is margin for paper shift in the printer and room for design inconsistencies.

Raster graphics are digital images created or captured (for example, by scanning in a photo) as a set of samples of a given space. A raster is a grid of x and y coordinates on a display space. (And for three-dimensional images, a z coordinate.) (looses Quality)

Vector graphics is the use of geometrical primitives such as points, lines, curves, and shapes or polygons—all of which are based on mathematical expressions—to represent images in computer graphics.
