A:Answer Printing cost = $0.25 + $0.7 + $0.15 = $1.1
Ink cost: Here we assume the graphic printing size to be A4 letter size. Generally speaking, an 1000ml ink valued $100 can support 400 prints in average. That’s to say, in this case each print cost 2.5ml ink valued $0.25.
Film cost: Here we assume the printer to be a sheet-fed version. 100 pieces of printing film cost $70, equivalent to $0.7 per sheet.
Powder cost: An A4 letter size print normally requires 1.5g adhesive powder. 1000g powder cost $100, that’s to say the powder cost of each print will be $0.15
Conservatively estimated, the cost of per custom shirt would be $6.6
