In roller printing, the print paste is supplied from reservoirs to
rotating copper rollers, which are engraved with the desired design.
These rollers contact a main cylinder roller that transports
the fabric. By contacting the rollers and the fabric the design is
transferred to the fabric. As many as 16 rollers can be available per
print machine, each roller imprints one repeat of the design. As the
roller spins, a doctor blade in
continuous mode scrapes the excess of paste back to the color trough. At
the end of each batch the paste reservoirs are manually emptied into
appropriate printing paste batch containers and squeezed out. The belt
and the printing gear (roller brushes or doctor blades, squeegees and
ladles) are cleaned up with water.
