An unwanted halo around the edges of the print, which is generally caused by in-correct printing pressures between the printing form and the substrate

1 Printing pressure is not uniform.
2 The printing pressure is too high and not regular and constant.
3 The printing forme or the mounting tape is too hard
4 Too much ink.

1 The forme carrier (sleeve/cylinder) concentricity is out of tolerances, control and correct.
2 Check the uniformity across the web and adjust the pressure.
3 Use softer printing formes. Check the hardness of the mounting tape.
4 Use an anilox roller with a lower cell volume.
