This study addresses the importance of the subjective quality evaluation and describes the lists of considerations for print quality evaluation. It demonstrates a practical test method of the subjective quality evaluation regarding test stimuli and psychophysical assessment. For the purpose of printer benchmark, subjective quality evaluation may contribute to two objectives. It provides to detect image quality attributes such as blurriness and raggedness for character and line attributes. Also, it gives the preference measurement which provides information about the overall image quality in a customer-relevant form. Considering two aspects, we represent quantitative ranking of printer performance in terms of image quality. For the universal printer benchmark point of view, it is quite necessary to analyze the printed image quality for developing printing systems, and extract the performance level comparing other competing models. Then, the quantitative ranking is acquired based on both the measurements from quality attribute metrics and the expectation of the preference level.
