It is most often useful in: * Helping minimize blobby strokes when drawing with low physical pressure near the pen's IAF * Smoothing out the inherent variations due to holding the pen with the hand and moving the pen across the textured surface of the tablet. See: * [Drawing at low physical pressure](/drawtab/core/pressure/drawing-low-pressure.md) * [Drawing smooth strokes](/drawtab/guides/drawing/drawing-smooth-strokes.md) ### Availability * Tablets - MAY perform some light pressure smoothing. * Drivers - MAY perform some light pressure smoothing. No drivers offer any direct control over pressure smoothing. * Applications - MAY support performing some pressure smoothing. If it is done, it might be directly exposed as something users have control over (see Rebelle) or it may be a part of other smoothing/stabilization features (Krita and Clip Studio Paint). Overall it is very rare for an application to explicitly mention pressure smoothing to the user. ### Pressure smoothing in Krita In Krita, in **Tools Options**, when **Brush Smoothing** is set to Weighted, there is a **Smooth Pressure** checkbox. Note that this pressure smoothing is NOT independent of the position smoothing. You can't have pressure smoothing without position smoothing.

### Pressure smoothing in Rebelle In Rebelle 8, You can open the **Line Smoothing** UI to configure pressure smoothing. Note that pressure smoothing is independent of position smoothing.
