Lucy in the Sky with . . . Polka Dots

Usually when I use my icing printer, I format the image to the size I want before printing.  I decided to play around with something new and print out a patterned page frosting sheet and cut it to fit my cutters.

Some of you have asked....my printer is an Epson WorkForce 30 Color Printer ; it is compatible with the food coloring cartridges.  You can find a list of all the compatible printers from KopyKake.  The printer itself is pretty affordable; it's the ink that is expensive....$90 for the set.  {That's why it took me so long to order one!  It was a major dent in my Starbucks fund.}

First, I ordered some digital paper from etsy.  Oh my gosh, there are SO many cute designs available!  I think I now have 100 digital papers in my arsenal.

{The smart thing would have been to TRY my idea before buying all of them, but I got a little carried away.}

Second, I printed the image on a full sheet of icing paper.

Third, using a food coloring pen, I traced the cookie cutters I used and then cut the icing sheets.

Forth, the cookies were outlined and filled with white royal icing.  While the flood icing was still wet, I applied the icing sheet.  It's not a perfect fit, so....

Fifth, after the cookies were dry, I went over the borders and added piping.

Do I love my icing printer?  Yes.  

But here's my problem with it...and maybe somebody can help me. 
The original image was this:

It looks so different on the cookies.

But, when I made these cookies, the colors stayed pretty true.  I'm so confused.

Anyone have experience with this they'd like to share?
