Ink spitting is caused by a buildup of ink on the opposite side of the blade, which then leaks out from the blade or contact point, creating teardrop shaped flaws in the print. Ink spitting is a random phenomenon that impacts the overall quality and profitability of an otherwise perfect print.

When white ink is not sufficiently opaque or homogenous, the final printed graphics may appear dull or grey. Increasing the printed ink weight by increasing anilox volume can improve opacity; however, there are obvious trade-offs concerning bond strengths for lamination — not to mention ink usage. White ink typically accounts for 30% of a converter’s ink costs.
