1. Get the weight of a full gallon of ink in grams. Then divide the cost of the gallon by the grams, to obtain the ink cost per gram.
2. Next, weigh the garment before printing and straight after printing (before curing). Subtract the non-printed weight from the printed garment weight, giving you the grammage of ink used.
3. Finally, multiply the grams of ink used per garment by the cost of ink per gram, which will total the ink cost per print.
You will find that the ink costs are low compared to other costs incurred in the screen printing process. The overall largest cost for screen printers is labour. Instead of worrying about ink costs, do everything in your power to streamline production and see your overall costs fall.
