In the past, I've used 2 differnt brand {Pink} Dual Cure Emuslsions..... Both are orange They turn a red color when you pour the Diazo in but when throughly stirred {about 10 minutes} it turns back to Orange.... after the screens are coated they will still look orange to you..... After exposure and washout and the screen has dried it will finally look pink..... Chuck Squirts T-Shirts
