Saw that you said you have doubts about the color reflection that I used. But how about the reflection of the knives, or other metal tools, there are no difficulties of printing there? No there aren't.
I want to assure you that every colored logo can be printed very good in B&W.
In B&W printing, all elements are printed in black. The shadows or other glowing effects can be obtained with a big distance between the printing raster points. A little printing tips : )
What do you mean when you say "rustic looking"? Please be more specific to help us, in creation of the right logo for you.
Thanks!
