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.

First claim

What is claimed is:

1. A top liner formation method, comprising:
for each of a plurality of lengths of a web substrate,
applying a print agent upon a first side of a length of the plurality of lengths of the web substrate without applying the print agent upon a second side of the length of the web substrate;
utilizing a dryer to dry the applied print agent and the length of the web substrate;
applying moisture to the length of the web substrate, with no dryer to be utilized to dry the web substrate length after the application of the moisture;
moving the length of the web substrate through a web extender after application of moisture to the length of the web substrate, the web extender including rollers that are not cooled by a cooling apparatus; and
winding the moisturized length of the web substrate upon a spool to form a top liner length following movement of the length of the web substrate through the web extender to allow time for absorption of the applied moisture.

2. The method of claim 1 , wherein moisture is applied to a second side of the length of the web substrate, the second side being on a side opposite the first side.

3. The method of claim 1 , wherein there is a delay of at least sixty minutes as between the winding of a top liner length upon the spool and adhering of a top liner length to a single face length to form a corrugated length.

4. The method of claim 1 , wherein the applying of the print agent to the length of the web substrate includes applying an ink film to the length of the web substrate utilizing a print engine.

5. The method of claim 4 , wherein the applying of the print agent to the length of the web substrate includes applying a primer coat layer utilizing a primer coater apparatus.

6. The method of claim 4 , wherein the applying of the print agent to the length of the web substrate includes applying an overprint coat layer utilizing an overprint coater apparatus.

7. The method of claim 1 , wherein the length of the web substrate is unwound from a first spool with the length of the web substrate having a moisture content within a baseline range, and wherein the formed top liner length wound upon the second spool has a moisture content within the baseline range.

8. The method of claim 1 , wherein the web substrate is an offset print media, and wherein the applying of the print agent includes applying a primer coat layer and/or an overprint coat layer to the web substrate.

9. A system for top liner manufacturing, comprising:
an unwinder component to unwind a length of web substrate from a first spool;
a print agent application component to apply an ink film to a first side of a length of the web substrate length utilizing a print engine without applying an ink film on a second side of the length of the web substrate;
a dryer component to dry the applied ink film and the length of the web substrate;
a moisture application component to apply moisture to a second side of the length of the web substrate following operation of the dryer component;
a web extender including rollers that are not cooled by a cooling apparatus, wherein the length of the web substrate is to be moved through the web extender after application of moisture to the length of the web substrate; and
a winder component to wind the moisturized length of the web substrate upon a spool to form a top liner length following movement of the length of the web substrate through the web extender, wherein no dryer is to be utilized to dry the length of the web substrate between the moisture application and the winding.

10. The system of claim 9 , further comprising a mist application apparatus to apply moisture to the length of the web substrate.

11. The system of claim 9 , further comprising a steam application apparatus to apply moisture to the length of the web substrate.

12. The system of claim 9 , wherein the length of the web substrate is unwound from a first spool with the length of the web substrate having a moisture content within a baseline range, and wherein the formed top liner length wound upon the spool has a moisture content within the baseline range.

13. The system of claim 9 , further comprising a corrugation component to, for each of a plurality of formed and connected top liner lengths,
unwind the top liner length from the spool; and
adhere the top liner length to a single face length to form a corrugated length.
