Abstract
An example method includes concentrating first printing liquid on a conveyor. Concentrating the first printing liquid produces liquid carrier having a low non-volatile solid concentration. The method also includes concentrating the liquid carrier having the low non-volatile solid concentration on a developer roller. Concentrating the liquid carrier having the low non-volatile solid concentration produces liquid carrier substantially free of non-volatile solids. The method also includes delivering the liquid carrier substantially free of non-volatile solids to a storage vessel.
Claims15
A system comprising:
- a conveyor;
- a first developer unit to:
- apply mechanical and electrical forces to a liquid carrier to separate the liquid carrier from residual non-volatile solids present in the liquid carrier and to produce second printing liquid containing the residual non-volatile solids, and
- deliver the second printing liquid to the conveyor;
- and
- a first squeegee unit to apply mechanical and electrical forces to first printing liquid on the conveyor to remove the liquid carrier from the first printing liquid and concentrate the first printing liquid.
A method comprising:
- concentrating first printing liquid on a conveyor, wherein concentrating the first printing liquid produces liquid carrier having a low non-volatile solid concentration;
- concentrating the liquid carrier having the low non-volatile solid concentration on a developer roller, wherein concentrating the liquid carrier having the low non-volatile solid concentration produces liquid carrier substantially free of non-volatile solids;
- and
- delivering the liquid carrier substantially free of non-volatile solids to a storage vessel.
An apparatus comprising:
- a conveyor;
- a first printing liquid tank;
- a first developer unit to:
- concentrate first printing liquid from the first printing liquid tank, and deliver the first printing liquid to the conveyor;
- a second printing liquid tank;
- and
- a second developer unit to:
- concentrate second printing liquid from the second printing liquid tank, and
- deliver the second printing liquid to the conveyor.
