"Ghosting" Problems and Remedies
When "ghosting" occurs because of premature drying of ink on the anilox roll, the following is a list of possible solutions or remedies to help correct this problem:
- If possible, put ghosting color on a back deck to utilize the full chamber for wetting.
- Change anilox for one with the same volume but with a coarser screen to bring the same ink to the plate but with reduced drying on the anilox.
- With solvent inks (and sometimes water), the viscosity may be too low. A higher viscosity should slow the drying on the anilox rolls
- Make sure the anilox is covered and protected from ambient air or blown air from dryers.
- Reduce blade pressure, which will reduce friction and heat at the sheer point of the ink.
- If possible, try to open the dwell time between blades or run trouble inks on decks that have enclosed systems with greater openings. This will assist rewetting of rolls.
