<Offset Printing Pins> Production Procedures: Preparing Films for each different colors → Printing colors (Each time by one color) → Baking at temperature of 180°C (Baking each time after one color printed) → External Shape Cutting → Soldering Attachment → Racking before plating → Electroplating if necessary → Epoxy Covering → Packing. Color reference: Offset printing is also named 4 color process printing (Yellow/ Magenta/ Cyan & Black), no matter how many colors involved on the art, we charge the printing set up fee for 4 colors only if there is no metal border left on the edge or 5 colors if metal border is necessary on the edge, the extra one is for white background color. Material: Based on different prices, there are 4 different materials for choices: A: Brass Material with gold or nickel plating (Most Expensive) B: Brass Material without any electroplating (Less Expensive) C: Stainless Steel without electroplating (Cheaper than Brass w/o plating) D: Aluminum material without any electroplating (Cheapest one)
