I have changed to a new type of paper and the paper recording is not as clear (Black/White) as it used to be.
The thermal printing paper delivered from RESON is high grade, steep slope paper. This means that the gradient between white and black is very steep. Therefore, the NAVISOUND is printing in a digital (On/Off) way, this paper produces crisp, clear images.
Other sources of paper generally have a slow gradient, resulting in an image that tends to have varying shades of grey with no black.
