If it is just a monogram, you could stencil it with either dark luster dust, or color gel, or even royal icing.
If it was edible paper, its possible they cut it the same shape/size as the bottom tier of the cookie so that the edges wouldn't show...
Not sure where you got this photo from, but I know that there are at least a couple of companies out there that have printers that print directly ON the cookie. Maybe this is one of them.
I usually use a stencil for mine and either use a dry brush or air brush over it.
there was a thread on these a while ago (maybe 2 yrs. ago) and it was determined (I think they found the actual person that made these cookies) that the jet decorating system was used (the link above) and it DOES print directly on cakes and cookies and if I remember correctly in was in the range of about $4,000 I believe
Here is the jet decorator in operation
KHalstead nailed it. I did a lot of research on this a while ago and that was indeed done with a jet decorator. I couldn't justify it yet at this point for myself, but it is oh, so neat! I spoke to a few people that had them and they were very pleased with theirs.
Thanks everyone for the wonderful information! Greatly appreciated!
Yes, it was me who started a thread with the same pic or something very similar. It was definately that expensive machine that prints onto the cookies. So cool.
The easiest and more economical way to do this is the stencil as gemini suggested, or edible paper.
I have done it both ways, edible paper and stenciling. For a monogram or something simple, I did RI stencil (had the stencil custom made at stencilease.com for around $20) See my pics of cookies. I also did cookies where they wanted "will you be my bridesmaid?" on the cookie and I did an edible image.
