If you are creating your own e-book comic, you can easily ink, draw and color your comic using Corel PHOTO-PAINT, and use CorelDRAW to layout the pages. Here is how.
1) Draw, ink and color your art in Corel PHOTO-PAINT at 300 dpi. Save original as a .CPT file and export/ or save as a JPEG, PNG or GIF at 96 dpi.
2) Import your art (96 dpi), into CorelDRAW (Ctrl + I). Set up your page sizes, and place your art.
3) When all text and speech bubbles are finished, just save as a PDF (File > Publish to PDF).
4) Log onto your favorite .mobi or other file format converter online, where you are going to publish and sell your comic. And then you are done!
