Help re image for custom engraving for Shruthi-1 case

Hi there

Just picked up the kit for the Shruthi 1 - really excited to put this together, sounds unique and fabulous.

I ordered the custom engraved option, but a bit confused about format. Do shades of grey work, or is it purely just black and white? Do you have an example image?

Many thanks, Ben

Shades of grey don’t work. Here is the “standard” image engraved on the cases:

Great, many thanks, I already have a black and white one sorted!

Cheers

Ben
