Important: Characteristics of White Ink
The usage and handling of white ink involves some important considerations that do not apply to ink of other colors.
Be sure to familiarize yourself with the characteristics of white ink before you use it.
White ink settles and separates.
➢
If it is allowed to stand, the precipitated material may solidify and cause clogging of the print heads or other
malfunction. Be sure to observe the cautions in this manual.
Periodic maintenance is necessary and must be performed without fail.
➢
We recommend operating the printer at least once a week.
➢
Maintenance must be performed at least once every two weeks, even when the machine is not in use. Allowing
it to stand may result in malfunction.
➢
Maintenance requires four SOL INK cleaning cartridges, so be sure to have these on hand.
Be sure to shake the cartridges before each use.
➢
Before starting the day’s operations, be sure to remove the white ink cartridges and shake them gently. Failing
to do this may result in faint color or cause breakdown.
Drying white ink
➢
Allow all ink (not just white ink) to dry sufficiently. Note that white ink in particular requires printing at a high
density, and so is more difficult to dry than CMYK inks.
➢
We strongly recommend using an auxiliary drying unit (DU-540) .
Using white ink out of doors
➢
Depending on conditions, the weatherability of white ink may be inferior to that of CMYK inks. The ink may
deteriorate and become powdery, peel or flake off, or smudge. We recommend performing lamination when
the white ink is to be used out of doors.
