Enlarging and Reducing Illustrations

Abstract

Although the usual procedure is to plan and prepare illustrations at the proper size for final use, if is often necessary to en­large or reduce rough draft artwork. There are seven techniques, ranging from man­ual to mechanical, for accomplishing this: free-hand sketching, the “squares” method, proportional dividers and vari­able scale, pantograph, projector, electro­static process, and photography. The first five techniques involve varying degrees of artistic skill, whereas the last two depend more on dexterity with machines. The first five methods produce a new size of rough draft artwork that must be finished with standard illustrator’s methods, but the last two may produce artwork ready for use in the final camera-ready copy.
