Hi Shapeways,
Today, I dyed a set of puzzle rings from two different production batches. I received the first batch two weeks ago, whereas I received the second batch today. I washed and dyed rings from both batches in a single dye bath. [list type=square]
[*] Yellow: 6 rings of batch 1 and 6 rings of batch 2
[*] Green: 2 rings of batch 1 and 2 rings of batch 2
[/list] As you can see from the photo below, the rings of batch 1 turn out significantly lighter than those of batch 2.
As I have treated the rings from both batches identically at my side (washed together, together in dye bath, rinsed together), the difference must be at the Shapeways side.
Can you explain these color differences?
Thank you.
Oskar
