As you are using an industrial enamelling process, as you described,
your best source of is from a ceramic ware maker ie
pottery, china etc maker. They apply all the designs by a tranfer
process. I do not know exactly the detail of this procedure, you
should contact a ceramic ware maker in your country for their
guidance. In our trade we apply enamel either by wet inlay, which is
not what you need or by sifting onto a prepared wet/adhesive design
on the prepared enamel surface.
The adhesive is gum tragacanth and if this was painted onto your
white enamel surface via a stencil, lift off the stencil, dust on the
enamel powder, and shake off where it has not stuck, this would give
you the decal design. Then after drying fire in the usual way.
I suggest you try this on some flat enamel surface first, then if it
meets your needs, progress to trying this on the curved surface.
If i could find an Easyjet flight to Tirana, I would come and help
