Glossary
Airflow
Air is blown through the printing zone to speed up the drying process.
Back tension
The backwards tension applied to the substrate by the input spindle, which must be constant across the width of the
substrate. Too much or too little tension may cause substrate deformation and print quality defects.
Bidirectional
Bidirectional printing means that the printheads print while moving in both directions. This increases the speed of
printing.
Bleeding
A print-quality defect that occurs when the ink spreads on the substrate across areas of different colors.
Coalescence
A print-quality defect that occurs when the ink coalesces on the substrate within an area of the same color.
Cockle
A substrate condition in which it is not lying perfectly flat, but rises and falls slightly in shallow waves.
Color accuracy
The ability to print colors that match the original image as closely as possible, given the fact that all devices have a
limited color gamut and might not be able to match certain colors precisely.
Color consistency
The ability to print the same colors in a particular print job, from print to print and from printer to printer.
Curing
The substrate is heated in the curing zone to coalesce the latex, creating a polymeric film which acts as a protective
layer, while at the same time removing the remaining co-solvents from the print. Curing is vital to ensure the durability
of the printed images. Too high or too low a curing temperature may cause print quality defects.
Cutter
A printer component that slides from left to right across the platen to cut the substrate.
Edge holder
A metal piece designed to prevent the edge of the substrate from rising while printing is in progress.
ESD
ElectroStatic Discharge. Static electricity is common in daily life. It is the spark when touching the car door, or the cling
of clothing. Although controlled static electricity has some useful applications, uncontrolled electrostatic discharges are
one of the main hazards to electronic products. Therefore, to prevent damage some precautions are needed when
setting up the product, or handling ESD-sensitive devices. This type of damage may reduce the life expectancy of the
device. One way to minimize uncontrolled ESDs, and therefore to reduce this type of damage, is by touching any exposed
grounded part of the product (mainly metal parts) before handling ESD-sensitive devices, such as the printheads or ink
cartridges. To reduce the generation of electrostatic charge in your body, try to avoid working in a carpeted area, keep
your body movements to a minimum when handling ESD-sensitive devices, and avoid working in low-humidity
environments.
