Ensuring good screen-film contact also ensures reduced: WebObtaining the best possible resolution may also require the use of a reduced focal spot (0.6 vs 1.2 mm), which will also require a reduction of the focal spot power loading (25 vs 100 kW). However, when a small focal spot is used with reduced power loading, the scan time may need to be increased, which also increases the likelihood of motion blur.
