What are GTT "sizes" and how can there be so few?

Now you can stop worrying about the sheer number of possible line and volume anilox combinations needed to run your print jobs.  Since each GTT "size" covers the range of two or more conventional anilox rolls, most printers only need two or three GTT "sizes" to perform all printing tasks.  So instead of calculating complex BCM, LPI, L/cm and cm³/m² formulae, just analyse the type of job you're going to print and select the appropriate GTT size.  For example:

  • For extreme opacity, use "XL"
  • For solid and screen combos, use "L"
  • Midrange and vignette, use "M" or "S"
  • Superfine line or dot work, use "XS"

It's really that simple!
