Title:
INK JET PRINTING SYSTEM
Document Type and Number:
WIPO Patent Application WO2000013906
Kind Code:
A3
Abstract:
In a first aspect, in a continuous stream ink jet printing system generating a plurality of streams of ink droplets, a chosen number of droplets of each stream is less than all of the droplets of the stream. A control means of the printing system is arranged to consider for printing from amongst a number of the droplets of each stream greater than the chosen number with the provision that the resultant selection made observes this constraint. In second and third aspects, a control means of the printing system is arranged to create a set of droplet print positions ideal for representing an image to be printed, which set is permitted to include print positions offset from print positions of a nominal matrix, at speeds of operation less than the predetermined speed the control means comparing the positions at which droplets can be deposited at the lower speed with the set of ideal positions, the control means deciding which droplets to print in dependence on the comparison.
