Issue/ Error Causes Solutions
Fuzzy blurry prints Table height is too low. Set the garment correctly on the platen,
and then perform HEIGHT ADJUST again.
Too much ink (oversaturated)
causing bleeding (mostly for
white or light shirts without
pretreat).
Check the settings in ColorGATE
Productionserver. Especially rendering
intent (perceptual is default and should be
used in most cases). Make sure you have
not changed profiles selection.
Nozzle check shows all
nozzles, but some areas show
deflection. (See page 124,
“NOZZLE CHECK”.
Perform normal nozzle cleaning or strong
nozzle cleaning, and then recheck the
nozzles to see if the deflection is gone.
For dark shirts with a white
Underbase, poor pretreat. Not
enough pretreat can make the
white can CMYK areas of print
to appear dull or fuzzy.
Especially if a section of the
print appears sharp and
another section appears dull or
fuzzy.
Check the dilution ratio of the pretreatment
and the coating/drying method again.
For details, see page 92, “Pre-treatment of
Dark Colored Garments”.
Head alignment is off.
Perform the head alignment procedure
(see page 175, “Adjusting the Head”).
Make sure to rule out the above reasons
before this adjustment.
Horizontal banding and
thin horizontal lines
across the entire shirt
Nozzles are missing. A nozzle
check may show some nozzles
are missing.
Perform head cleaning of CMYK print
head to clear the clogged nozzles.
Nozzles are all accounted for,
but some are showing minor
deflection.
Check the table height. The effect of any
deflection can be exaggerated if the
printing surface is too far away from the
head. Set the garment correctly on the
platen, and then perform HEIGHT
ADJUST again.
Perform head cleans until the deflection is
reduced.
Nozzles are 100% and little to
no deflection.
Perform the table alignment procedure
(see page 178, "Adjusting the Table").
