Glossary Aerosol filter The printheads produce many fine droplets of ink, most of which are placed accurately on the substrate. However, a small proportion of these droplets escape sideways; the two aerosol filters 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 different 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 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, 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 specific set of numbers. Many different color spaces can use the same color model: for instance, monitors generally use the RGB color model, but they have different color spaces, because a particular set of RGB numbers results in different colors on different monitors. CSR Customer replaceable parts. Curing Curing is needed 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. Drying The heat applied in the printing zone removes water and fixes the image to the substrate. Glossary 333
