Hi I am a newbie, and I would like to attempt a chocolate transfer of my husband's company logo onto a cake for a new employee luncheon they are having this Friday. My question is can I use toll house chocolate chips melted down or do I have to buy a specialty chocolate for this to work? I bought white chocolate chips-- can I add wilton colors to this to get the colors I need ( i just need red and white). Thanks! 
1. Regular semi-sweet chocolate chips can be tricky, because if you don't temper them (involves heating and cooling to specific temperatures), they are likely to have problems. It can be done, but the results aren't as consistent. Candy melts, also called confectionary coating or summer coating, are easier to work with, but don't taste as good.
2. Chocolate doesn't do well with any kind of water, including the water-based Wiltin icing colors. Wilton does make candy colors, which are oil based.

I would also recommend candy melts or a confectionary coating (like almond bark it is called around here) It is not real chocolate, but it sets up hard after it is melted. If you use regular chocolate I think you would need to temper it.
I have done quite a few of these and personally I prefer to use the pre colored candy melts. I will color them when I have to with candy colors.
carries_creations, As the others have said candy melts or almond bark do work much better, but in a pinch you can use chocolate chips, melt them slowly, heat just to begin melting and stir until remander of lumbs are out, then add either veg. oil or shortening like crisco, a little at a a time, you also can use wilton colors, however red is a hard one, you have to add alot a little at a time, and the wilton colors will seize up your chocolate, you conter this by adding more oil or shortening as you go. Chocolate transfer are the greatest, and it is best to start with the right materials, and those can be just a matter of preference or whats available in your area.
