[Supplies: Tinsel Town - Melissa Bennett, Tinsel Town Stamps - Melissa Bennett, Oh Christmas Tree - Lauren Grier, Sweet Holiday Digital Stamps - Julie Billingsley (all from SSD) ...plus Copic markers.]
I made this card using supplies and digital stamps from Sweet Shoppe Designs and started off with 4 digital stamps (ie. just the black outlines). I printed this onto the usual cardstock that I use with my Copics (Georgia Pacific) and I used my Canon printer (I always use genuine Canon ink).
Ooops...looks like I should have done more of a close-up on what Copic colours I used - sorry about that :( Hope you can still make them out.
Anyway, I took great care in not necessarily colouring over or on top of the lines, so I guess you could say that I was pretty careful, but... for me, Copics and my printer worked just fine! I'm so excited about this as it means a who new world is open to you with all the digital stamp designs too :)
Of course I can't guarantee that this will work for everyone and different cardstock and/or printer/ink might not give the same results. The little experience I have had with "compatible printer ink" (which I really won't touch since then!) makes me think that this could possibly have a worse result too... but as I said, I really don't know.
If you want to try for yourself I would just recommend being very careful at first (you don't want to ruin your expensive markers!!) and go very carefully up to the printed lines. Colour a little and then wait and see what happens before you colour the whole image and potentially could suddenly find yourself with your marker tip stained with printer ink (horror!!).
...I also used a Spica At You glitter pen to go over some parts of my coloured/shaded images. You can never have too much glitter :)
I hope this little experiment and the info was useful to some of you. :)
