I want set ink order in Affinity Publisher. Is related how silver, gold, white, gloss is printed using xerox modern digital printing machines. because if white is printed first i can use it get stuff in black paper. and if silver/gold its same plus i can tint them with cmyk colours to make metallic copper, metallic blue, metallic green and such. if possible already i want know.
