The brush selector
Tap the brush icon to open the brush selection screen.
You have twelve brushes to choose from. Each brush remembers the colour you last used with it. Each brush can be modified extensively -- they are all functionally the same, they all just have different starting characteristics.
Choosing a brush
The current brush is always shown highlighted in blue.
To select a different brush, tap it. If you tap quickly, you will return to the drawing screen immediately with that brush selected. If you tap and hold, the brush will be selected but you stay on this screen.
Brushes and colour
Brushes remember the last colour used; when using a new brush it will start as black. To choose a different colour for a brush, tap on the palette icon and choose a colour.
Brush width
Use the lower slider to control brush width from 0.1mm to 100mm (about a hair's width to four inches).
Brush width is accurate when compared to the size of the page.
Brush density
Use the upper slider to control density from 10% to 100%
Density is how much pigment (or ink) is put on the paper with each stroke.
Bristles and medium
Tap the preview pad (at the top of the screen) to change both bristle shape and painting medium.
Each tap changes the brush in the following sequence:
- Round bristles, pigment
- Round bristles, ink
- Square bristles, pigment
- Square bristles, ink
Pigment and ink
Understanding the difference between pigment and ink is important to getting the most natural look from your PaintBook art.
Pigment is opaque
Pigment colours are opaque. As you lay down more and more pigment, the colour on the page becomes more and more like the true pigment colour.
White pigment can be used as an eraser, as long as your paper is white.
Ink is transparent
Ink colours are transparent, and always darken the paper. As you lay down more and more ink, each stroke on the page darkens. Eventually, nearly all ink will overlap to black.
White ink is completely transparent, and has no use at all!
