dabs: The closer they are together, the harder the line is. By default, this is 0.1, which is a bit low. If you set it to 10 and test, you’ll see what kind of effect spacing has. The Auto checkbox changes image for computer consumption, this is the default. 120 PPI This is often used as a standard for low-quality posters. 300 PPI This is the minimum you should use for quality prints. 600 PPI The quality slowly start building up your animation. During the sketching phase it may also help to work on a low resolution, like 800×450 pixels. High resolution only starts mattering when you are doing line art
