1： Epson printer ink cost

　　1. Ink cost required for printing flat effects

　　The unit price of Epson ink is 300 yuan/liter, and 1 liter can print 80-100 square meters. The cost calculation is as follows:

　　300 yuan/80 square meters=3.75 yuan/square meter (rounded to 4 yuan per square meter); 300 yuan/100 square meters=3 yuan/square meter, plus ink loss and other costs of about 1-2 yuan/square meter, therefore the ink cost for Epson tablet printers is between 5-6 yuan/square meter;

　　2. The ink cost required for printing relief effects

　　Relief is made by stacking ink. Generally, the ink cost of relief effect is increased by 80% on the basis of the flat effect, plus the loss. Calculated at twice the flat effect: 10-12 yuan/square meter

　　3、 The cost calculation for coating or varnish treatment is as follows:

　　The price of ordinary coating is 60 yuan/liter, and 1 liter can spray 60 square meters. The cost of coating/ordinary varnish is: 60 yuan/60 square meters=1 yuan/square meter; (The cost of high gloss gloss oil is generally 5 yuan/square meter, which is usually used with a coating machine.)

　　The labor cost varies from place to place, calculated according to the minimum wage standard in Shenzhen, which is 2130 per month.

　　5： Electricity bill

　　Similarly, the charging standards vary from place to place. Calculated at 1 yuan per kilowatt hour, the machine speed is also calculated at 20 square meters per hour. The machine has a power of 3km, with 1kw/h * 3kw=3kw/h, which means one hour at 3 degrees Celsius. The cost is 3 yuan per hour, and if 20 square meters are produced, then one square meter is 0.15 yuan.
