Abstract: In one example of the disclosure, a print agent is applied upon a length of web substrate. A dryer is utilized to dry the web substrate length. Moisture is applied to the web substrate length. The moisturized web substrate length is wound upon a spool to form a top liner length, with no dryer to be utilized to dry the web substrate length between the moisture application and the winding.

Abstract: A pre-treatment coating composition can include an evaporable liquid vehicle and a pre-treatment coating matrix carried by the evaporable liquid vehicle. The pre-treatment coating matrix in this example can include from 30 wt % to 70 wt % multivalent organic salt including a multivalent metal acetate or a multivalent metal propionate, from 5 wt % to 30 wt % dispersed polymeric binder having a weight average molecular weight from 20,000 Mw to 1,000,000 Mw, from 0.5 wt % to 8 wt % of a high molecular weight polyvinyl alcohol binder, and from 10 wt % to 30 wt % of a low molecular weight polyvinyl alcohol binder. The low molecular weight polyvinyl alcohol binder and the high molecular weight polyvinyl alcohol binder in this example can be present in the pre-treatment coating matrix at a 3:1 to 15:1 weight ratio. Weight percentages in this example are based on dry weight of the pre-treatment coating matrix.
