If you are using a vector file that has been created or imported into CorelDraw or Illustrator, then creating the underbase file is usually simple. You will need to create an exact duplicate of the file and then change all of the pieces and outlines in the image that are to be underbased into black. the next step would be to adjust for any trapping by adding a small white outline to the appropriate parts of the image.
Deciding whether or not to use an underbase for a color can be complicated, involving a lot of factors that will affect the final print. Many printers throw in the towel and just underbase everything in the design. Of course, this makes the shirt feel as though a big plate of ink is sitting on top of it, and it also tends to make all of the top colors that are not flashed immediately begin to bleed outside of their image area.
