A printed document includes a print quality indicator on the print surface of the document in the primary printing area. The image of the print quality indicator has a plurality of printed targets, each of the targets defining an unprinted area. The dimensions of the unprinted areas of the targets varying among the targets. The print quality of the printed document is determined by noting which of the unprinted areas in the print quality indicator printed on the document are not clearly free of ink upon close visual inspection of the document. Each target is made up of a printed circle, having a specified outer diameter, a specified line weight, and a specified inner diameter, and a printed circular dot, having a specified diameter, positioned centrally within the printed circle. The specified diameter of the printed circular dot is less than the specified inner diameter of the printed circle such that the printed circular dot and the printed circle define an annular unprinted area there between.
