We manufacture make up comptible to Markem Imaje CIJ printers. A188, 5191, cleaning solution, etc. For these make up, we usually add pink, purple or black color additive in it or just leave it to be transparent if you like. But for easy customs clearance, we suggest that it will be better to add in some color.
