Scaling ArtworkIntroductionNot all mechanicals are comprised of text only. You must know how toproportionally scale art and photographs to fit into a predetermined space.Scaling is calculating the dimensions for a reduction or enlargement of agiven image. You can use a slide rule, a mathematical formula, the diagonalline method, or a scaling wheel to scale artwork. This segment will coverthe most common and easily available methods, the diagonal line method andthe scaling wheel which is often called a proportional scale.Diagonal lineThe diagonal line method reduces or enlarges the size of the original artworkor the size of the allotted space in the paste-up or mechanical.To use the diagonal line method, use this table:StepAction1Cover the allotted space on the mechanical with tracing paper or anoverlay.2Using a straightedge and a pencil, draw the outline of the allottedspace on the paper.3Extend the left-hand vertical line and the lower horizontal line.4Using a triangle, draw a line from the lower left-hand cornerthrough the upper right-hand corner of the outline.5Place the overlay on top of your original artwork aligning the leftside and the bottom.6Determine whether the height or width is most important for yourimage.7Mark the line corresponding to your selection of the most importantdimension and extend this line to the diagonal.8Using your straightedge, draw a line from where the last lineintersected the diagonal to complete the box or rectangle.Continued on next page1-38
