Illustration of a print-tip group effect. The eighth Y-orthogonal loading vector po,8T displayed using a spatial representation of the array layout. The 48 print-tip groups are delimited using solid lines. Darker areas denote higher absolute loading values whereas brighter areas denote lower absolute loading values. One distinct print-tip group with high-magnitude loading values can be seen in the upper right corner of the figure (indicated by the arrow), capturing a print-tip group effect.
