They are drawn by hand, 100% digitally and on the screen: The interactive Pen Display (WACOM Cintiq21UX) replaces paper, pen and colour.

Even the sketch is done digitally on the screen and can be sent as a fully scalable pdf-file via email immediately after completion - no scanning required.

After agreeing on the sketches and carrying out eventual corrections the colour is added digitally as well. So there are no blemishes common in scanning analogue drawings - even thorough corrections are possible at any time and the finished result can be sent electronically and is print-ready immediately.
