ink chamber The ink chamber links the ink store with the drop formation and its controlled
dispersal onto the textile substrate; however, it acts as more than a reservoir. As
the ink drop leaves the nozzle, fresh ink is drawn into the ink chamber to fill this vacant
space. In print heads using a thermal activator or “acInks for ink jet printing come in a variety of formulations, and as the main component
running through the print head, they also have an impact on its design. Inks will be
discussed in more detail in Chapter 7 of this book, but in most cases, they are essentially
colorants in fluid. The fluid is either a “solution” with dyestuff fully dissolved
throughout, or a “suspension” carrying microscopic solid particles of pigment. Generally,
dyestuff in solution will print translucently, whereas pigments are more opaque,
and the software driving the printer adjusts the print information accordingly. Ink
types could also be defined as water (aqueous) based or solvent based (usually using
oil or alcohols). Running an alternative ink type through the print head may not only
give unsatisfactory print results, but may also damage a print head designed for a different
ink type. Print heads may need to be matched not only to ink types, but also to
certain formulations of these, as brands vary. The print head is made from small and
sensitive components, so only a small change can have a visible effecttuator,” the chamber is where the
heating element sits, bringing the ink up to the appropriate temperature. The ink chamber
may also include sensors that monitor and control ink levels, temperature, and
pressure as well as filters to remove air bubbles and debris carried by the ink. Removing
undesirable air bubbles is sometimes known as “degassing.” Agitators may also be
incorporated as well as elsewhere in the ink jet system to “stir” the ink to mix the component
chemicals, particularly pigments. Different types of thermal or piezoelectric
print heads may or may not be compatible with different ink jet types and even different
manufacturers’ formulations within these types. Incompatible combinations
might damage the costly print heads themselves as well as ruin a print run. This is
one significant reason why many ink jet printer manufacturers often recommend particular
brands of ink to be used in conjunction with their brand of printer.
