Classic ink vs. Craft ink?

I felt it was time for a little Q&A session with 'Dear Jodie, the Stampin' Lady'. Not because I've gotten a lot of questions but because this was something that confused me for sometime when I first became a stamper and to make myself feel better I thought that maybe others were confused by this too. So the question I'm going to answer today is "What is the difference between classic and craft inks?"

Here is the low down straight from the souce (Stampin' Up! product guide for demonstrators)

Classic Ink - good for day to day stamping and the only ink most stampers will need (note: this is my comment).
■ Water-based dye ink
■ Basic Black and Basic Brown are made with waterproof dye ink and will not bleed on Stampin’ Up!’s card stock
■ Slightly raised fabric pad
■ Cannot be used on vellum or plastics

Craft Ink - takes longer to dry so more patience is needed. Craft ink does have its place but you will probably only ever need to get the stampin' spots to fulfill your needs (note: this is my comment).
■ Pigment ink
■ Slightly raised foam pad
■ For use in scrapbooks as well as on wood, fabric (see below), and other craft items (ie, plastics, vellum)
■ Opaque look on coloured card stocks
■ Great for embossing

This ink is thicker than our dye-based ink (classic ink), so you use more each time you stamp; we recommend keeping an ink refill handy so you can re-ink the pads.

Let Craft ink dry for a bit or heat set before adding photos or other embellishments.

You’ll get better results on fabric if the pad is well inked. Be sure to hold the inked stamp on the fabric for at least 30 seconds. For best results when stamping on fabric, use a tightly woven or smooth finished fabric and heat set. Line dry stamped fabrics to avoid fading. Always pretest the ink on a small swatch of fabric, as fabric finishes vary greatly. Be sure to prewash all of your fabrics before stamping.

The following colours do not work well on fabrics: Only Orange, Really Rust, More Mustard, and Whisper White.

We do not recommend Craft ink for stamping on walls; we recommend that you use acrylic paint.
