Measurement and compensation of printer modulation transfer function
bstract. The capacity of a printing system to accurately reproduce etails has an impact on the quality of printed images. The ability of system to reproduce details is captured in its modulation transfer unction (MTF). In the first part of this work, we compare three exsting methods to measure the MTF of a printing system. After a horough investigation, we select the method from Jang and Alleac...
متن کاملCompensation of printer MTFs
Preliminary experiments have shown that the quality of printed images depends on the capacity of the printing system to accurately reproduce details. We propose to improve the quality of printed images by compensating for the Modulation Transfer Function (MTF) of the printing system. The MTF of the printing system is measured using the method proposed by Jang and Allebach, in which test pages c...
متن کاملCompensating Printer Modulation Transfer Function in Spatial and Color Adaptive Rendering Workflows
Experiments have shown that the quality of printed images depends on the capacity of the printing system to accurately reproduce details. We propose to improve the quality by compensating for the Modulation Transfer Function (MTF) of the printing system. The MTF of the printing system is measured using a modified version of the method proposed by Jang and Allebach [1]. Then the MTF is adaptivel...
متن کاملModulation Transfer Function Measurement Using Three- and Four-bar Targets.
Modulation-transfer-function (MTF) measurement often involves the use of three- and four-bar resolution targets. In the conversion of three- and four-bar image data to MTF, biased results can occur when we use series-expansion techniques appropriate for square-wave targets of infinite extent. For systems where the image data are digitally recorded, a convenient and accurate conversion of bar-ta...
متن کاملModulation transfer function measurement of a multichannel optical system.
We present a new method to measure the modulation transfer function (MTF) beyond the Nyquist frequency of a multichannel imaging system for which all the channels have parallel optical axes. Such a multichannel optical system produces a set of undersampled subimages. If the subimages contain nonredundant information, high spatial frequencies are folded between low spatial frequencies, leading t...
