Should you have a monochrome version of the logo?

Yes, because the stamp, the embroidery, the photocopy and the engraving do not print the palette. Without that version, each supplier invents a different black. List what is done in one ink this year: stamp, apron, frosted glass, a supplier's copy. That defines the file. The colour logo is sent to the embroiderer and the thread comes out as an approximation. On the shirt at Clínica Dos Ramos the mark is not recognised. The mark in black and in white, tested on the real cloth or paper, inside the master folder. The sheet says which goes on the stamp and which on the dark apron.
