USING PRE- AND POST-HEATERS.
Use the Pre- and Post-heater for uncoated or slow-drying media. With the Heaters you
can get a wider range of media compatibility.
When using the heaters set it on the maximum temperature.
Important :
Depending on the use of media, it is possible that media starts to curl.
If this is the case, lower the temperature.
USING ECO-SOLVENT INK
•
Before installing or changing to Eco-Solvent ink, perform a Head Wash. The tubes and
heads must be clean. Use the special Eco-Solvent Transition Liquid.
•
Once you have worked with eco-solvent inks, it is forbidden to change to another ink
type.
•
Prints are UV- and water-resistant for up to three years outdoors (*). Lamination is
required for heavy-duty applications.
•
No need for special ventilation or environmental equipment.
(*) Accelerated weather tests predict up to 3 years outdoor durability. Outdoor durability is
location and application dependant.
USING PIGMENTED INK
•
Pigmented ink tends to dry faster than dye ink. Make sure to clean the head cleaning
wiper regularly in order to avoid head clogging.
(See section: cleaning head cleaning wiper)
•
Pigmented inks at all times require the ink density to be set to NORMAL. These inks
are not compatible with FAINT nor with THIN ink density mode which both use the
micro-dot printing mode.
•
If you have a RIP software in which media profiles are available for the Mutoh ink/media
combination, the software normally should disable the micro-dot mode as soon as a
profile for pigmented ink is selected. It is best however, always to double check this.
