.ai is the ending for files that have been created with the vector graphic program Adobe Illustrator.
A color produced by light falling onto a surface, as compared to subtractive color. The additive primary colors are red, green and blue.
Software used for creating high-resolution, vector-based graphics.
A detailed sequence of steps for solving a logical or mathematical problem or performing a task.
A special 8-bit grayscale channel that is used for saving a selection.
A key element in vector graphics. An anchor point is the part of a path that "ties the path down to the page." Paths (also called curves) can be defined by using the mouse to select anchor points and directions. A line will have at least two anchor points on either end. Anchor points remain in the same position whether turning, bending, enlarging, reducing or mirroring the object. These anchor points do not print out but they shape the paths that appear on the hardcopy.
The blending of pixel colors on the perimeter of hard-edged shapes, like type, to smooth undesirable edges (jaggies).
An application or software program is a software executable designed to perform a specific function. Adobe Photoshop is an example of an application designed to perform image editing. Microsoft Word is an example of an application designed to perform word-processing.
All original copy, including type, photos and illustrations, intended for printing. Also called art.
A function in illustration software that creates paths along the edges of a scanned sketch. A common way to begin a drawing is to create a pencil or ink drawing and scan that. This scan will be used as a template over which the auto tracing occurs. The next step is typically to clean up the paths the auto trace function created and then discard the template scan file. There is significant concern when using auto trace functions that the shapes will be overly complex (too many anchor points) and will not output. This is a leading cause of output failure.
