"Currently three methods are available for applying the “Ident” to the PCB.
- Manual screen-printing can be utilized when line widths are greater than 7 mil (0.007”) and the registration tolerance is 5 mil.
- LPI (Liquid Photo Imaging) provides more accuracy and legibility than manual screening and is employed when line widths are greater than 4mil.
- DLP (Direct Legend Printing) is the most accurate and legible of the 3 processes but also has the highest cost for consumables."
