PLOTTING CHARACTERISTIC CURVESOnce the graph is labeled, use a densitometer and read the densities ofthe sensitometric strip and plot them on the graph to form a curve.Assume that the sensitometric strip has the following density readings:To plot these densities on the graph, find thedensity value reading of step 1 and place a dot at thatpoint. Do the same with steps 2 through 21, as shownin figure 24. After plotting all the readings, connectthe plotted points with a french curve and straightedge(fig. 2-5). You do not necessarily want to connecteach plotted point. The resulting curve should be asmooth, flowing line with no angles apparent.Remember to label every graph with all thepertinent information, because information that is notrecorded on the graph may be lost or forgotten.
