The document discusses key principles of design used in graphic arts, including balance, emphasis, pattern/repetition, proportion, movement, rhythm, contrast, and unity. Balance refers to visual equality in elements like shape, form, value and color that can be symmetrical or asymmetrical. Emphasis creates a center of interest to attract attention. Pattern and repetition unify a work through consistent visual elements. Proportion concerns the relative size of elements. Movement directs the eye along lines and colors. Rhythm relies on pattern and movement to create order. Contrast arranges opposing elements to make visual interest. Unity occurs when all elements combine into a harmonious whole.
