Abstract
Marangoni flow induced print defects are alleviated by underprinting and/or overprinting by a primary ink-jet ink with at least one treating solution that is capable of inducing the precipitation of the colorant in the primary ink-jet ink upon sustained contact. Since the time scale of precipitation is fast compared with the development of print defects due to Marangoni flow, the deleterious effects of Marangoni flow are forestalled. The method of the invention offers an effective and easily-implemented solution to the problem of Marangoni flow induced print defects that supplants the use of specially-treated paper and its associated high cost and inconvenience.
