Printing on acrylic photo blocks

[Lana_ZL]

Hi all!
Tell me, please, does anyone know if it is possible to print on acrylic photo blocks with a transparent background? Or instead of a transparent background, which is on my design, will white be printed in these places?

i just tested a photo block using a transparent png image on one of the side panels. In the layer it shows as transparent, but the preview  of that transparent  layer on the block shows a white bkgrnd,and  on all the other panels. Clicking done, the transparent panel shows a white bg. Also while In layers, tried clicking on transparent instead of white, in colors, stayed white.
So it had a white background and can’t be removed. But, you can change the bg color from white to another color, for example, blue or black….

Thanks for the answer. But the problem still seems to be there.
My design is conceived in such a way that transparent places are left where necessary. It looks great in Photoshop, but with this product, I probably won't be able to show it to the customer exactly as it was intended. With a white background, there is no such charm as with a transparent one. Today I started uploading my designs on photo blocks and noticed the difference.

Has anyone seen the PHOTO BLOCK in person? I haven't. 

I believe that the image is printed on paper that is then adhered to the back of the block - I could be wrong. The paper is white in the "blank" spots.

Yes, you are correct. I have actually ordered a few of them for gifts. I love how they look! Zazzle does a great job with the printing.
