As far as using digi's, you have to know a few things;
First of all, the type of printer you have. Is it ink jet or laser? Most people have ink jet because laser printers are the costlier ones.
Some inks in an ink jet printer will run with Copics, others won't. Test it out before you begin colouring an image. If you have the type of ink that runs, try heat setting it. That should set it enough to use.
Also check that your printer can take card stock That is something else you need to test out, because card stock is thicker than printer paper! If it is a problem, there's a trick I learned from Holly. Just tape an inch wide row of regular printer paper to the top of your card stock and feed that end in first. The printer can grab the printer paper and it should go through smoothly.
If you do have laser printer, you will def. have to heat set because lasers don't use ink, they use a type of embossing powder. And if you are putting card stock in the printer, it is too thick for the heat of the printer to adequately penetrate the page. So heat setting is a must. But you can't use Copics with laser printers! The alcohol in the markers just eats through the embossing and demolishes it! But you can colour with Prisma pencils or water based inks or paints when using a laser printer.
To print off the images, I recommend opening Word (if you have Microsoft Word program). Here is what I do:
