– Image Armor CLEANING SOLUTION:
The nozzle tips of any spray system are a wear item in the Viper XPT and will over time due to a
variety of factors, erode the spray tip causing poor spray patterns. Below are several of the
common factors that can cause spray tip degradation and poor pretreatment machine
performance.
1. Erosion:
Erosion is the gradual removal of
nozzle material which causes the nozzle
orifice and internal flow passages to enlarge.
When this happens your spray pattern will
change and additional pretreatment will be
applied to the garment in comparison to
when the tip was new.
2. Corrosion:
Some pretreatments that are used
in DTG printing are very highly corrosive. This
can cause the nozzle material to wear internally as well as externally, enlarging the
orifice and corroding the spray tip features causing irregular spray patterns.
3. Caking/Bearding:
This is the build-up of
pretreatment material on the inside or
outer edges of the orifice. Most typically
if nozzle tips are not cleaned and flushed
daily, pretreatment can dry and build up
on the tips. Many times this is
imperceptible to the naked eye, but this
build-up can cause irregular spray
patterns by obstructing the orifice and/or
flow passages inside the tip.
4. Accidental Damage:
Use of improper cleaning tools can result in scratches that can
affect nozzle performance and spray patterns. Dropping the tip during maintenance or
installation can also damage the nozzle tip causing irregular spray patterns. When
cleaning the Viper’s spray tips, use only a soft bristle toothbrush and Image Armor
