How much ink do I need for screen printing?
The result will be the total volume of ink you’ll need. To cover test prints, setup, and slight overage, it’s generally wise to inflate the final number by another 5%–just in case….Inks & Coatings.

How is ink coverage calculated?
Ink coverage is specified as a percentage: using 100% of each process color (cyan, magenta, yellow and black) equals 400% TIC….The following percentages are industry averages:
- Sheetfed offset on coated paper (typical commercial printing jobs): 320 to 340%
- Heatset web offset (such as magazines): 300 to 320%
- SWOP: 300%
How is print area calculated?
Calculate the area of paper being used (are you printing on 8.5in x 11in sheets? 24in x 36in sheets?) [Area= Length x Width] 2. Multiply the paper area by the ink coverage percentage to find the total area covered in ink of ONE SHEET OF PAPER (convert the percentage to a decimal) 3.
What is ink mileage?
Ink mileage is a method to determine how much ink that is required for a certain target density. Further tests on the same substrates have been done including print through and surface roughness measurements.
How many shirts can a quart of ink print?
200-500 shirts
A quart of ink can usually print 200-500 shirts. This wide range is because light designs on dark cloth usually use twice as much ink.
How is page coverage calculated?
On an average a normal print page consists of 20% coverage. So cartridge “A” in real conditions will have 20/5= 4% Page coverage. And the number of pages it will actually print will be a maximum of 1600/4= 400 Pages. Similarly, cartridge “B” in real printing conditions will have 20/10= 2% Page coverage.
How long should I expose my screen?
Determine the increments of time with which you will be exposing your screen. For fast burning emulsions you will use small increments (5-10 seconds), for slower burning emulsions you will use 30-60 second increments.
