A business letter is usually used when writing from one company to another, or for correspondence between such organizations and their customers, clients and other external parties. The overall style of letter depends on the relationship between the parties concerned. Reasons to write a business letter include: to request direct information or action from another party, to order supplies from a supplier, to identify a mistake that was committed, to reply directly to a request, to apologize for a wrong, or to convey goodwill. A business letter is useful because it produces a permanent written record, is confidential, and formal.
There are two main styles of business letters:
In typography, leading // refers to the distance between the baselines of successive lines of type. The term originated in the days of hand-typesetting, when thin strips of lead were inserted into the forms to increase the vertical distance between lines of type. The term is still used in modern page layout software such as QuarkXPress and Adobe InDesign.
In consumer-oriented word processing software, this concept is usually referred to as "line spacing" or "interline spacing."
Graphic design is the art of communication, stylizing, and problem-solving through the use of type and image. The field is also often erroneously referred to as Visual Communication or Communication Design due to overlapping skills involved. Graphic designers use various methods to create and combine words, symbols, and images to create a visual representation of ideas and messages. A graphic designer may use a combination of typography, visual arts and page layout techniques to produce a final result. Graphic design often refers to both the process (designing) by which the communication is created and the products (designs) which are generated.
Common uses of graphic design include identity (logos and branding), publications (magazines, newspapers and books), print advertisements, posters, billboards, website graphics and elements, signs and product packaging. For example, a product package might include a logo or other artwork, organized text and pure design elements such as images, shapes and color which unify the piece. Composition is one of the most important features of graphic design, especially when using pre-existing materials or diverse elements.
