Document Type and Number:

WIPO Patent Application WO/2018/094715

Kind Code:

A1

Abstract:

A method of treating an aluminium printing form precursor for use in lithographic printing. The treatment conditions comprise a relative humidity of at least 30 ％, a temperature in the range 60 to 120 ℃, a pressure of from 0.9 to 10 atmospheres and a treatment time in these conditions of at least 10 minutes. The method may be used for preparing an aluminium printing form precursor for imaging and subsequent printing. The method may provide a beneficial decrease in hydrophilicity and a beneficial increase in oleophilicity of the aluminium printing form precursor. An improved aluminium printing form precursor is also described.
