Aerosol lter
The printheads produce many îžne droplets of ink, most of which are placed accurately on the substrate. However, a
small proportion of these droplets escape sideways; the two aerosol îžlters are placed on either side of the printhead
carriage to intercept them.
Bleeding
A print-quality defect that occurs when the ink spreads on the substrate across areas of diîž«erent colors.
Carriage beam
The beam supporting the printhead carriage as it moves back and forth across the printer.
Coalescence
A print-quality defect that looks like a higher level of whiter grain.
Cockle
A substrate condition in which it is not lying perfectly at, but rises and falls slightly in shallow waves.
Color accuracy
The ability to print colors that match the original image as closely as possible, bearing in mind that all devices have a
limited color gamut and may not be physically capable of matching certain colors precisely.
Color consistency
The ability to print the same colors from a particular print job from print to print and from printer to printer.
Color model
A system of representing colors by numbers, such as RGB or CMYK.
Color space
A color model in which each color is represented by a speciîžc set of numbers. Many diîž«erent color spaces can use the
same color model: for instance, monitors generally use the RGB color model, but they have diîž«erent color spaces,
because a particular set of RGB numbers results in diîž«erent colors on diîž«erent monitors.
Curing
Curing is needed to coalesce the latex, creating a polymeric îžlm 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.
Drying
The heat applied in the printing zone removes water and îžxes the image to the substrate.
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 the electronics 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 or render it unusable. One way to minimize uncontrolled ESDs, and therefore 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). Additionally, to reduce the generation of electrostatic charge in your body try to avoid
working in a carpeted area, and keep your body movements to a minimum when handling ESD sensitive devices. Also,
avoid working in low humidity environments.
