Embodiment Construction

[0025] figure 1 A schematic diagram is shown of a possible embodiment of the invention, where the invention may be provided, for example, as a successor to a digital printing device. It is also possible to integrate the device shown as an accessory into a digital printer or device. In the device shown, the printing substrate or paper 1 enters the primary cooling zone 2 after entering the device through the entry zone. This cooling zone may comprise a cooling plate close to the paper 1 in a dry cold gas stream, or any other known system. In this first cooling zone, in the embodiment shown, there is a second zone where cooling is provided by three rolls 3, 3', 3", the central roll of which has a movement to vary the cooling rolls 3, 3', 3". Capability of contact angle between 3" and paper 1. The role of these rollers may be similar to that disclosed in documents ES2222089 and ES2222110, both of which correspond to the invention of the inventor of this patent.

Abstract

Method for conditioning paper, which comprises a first step of cooling and one of applying a liquid to the paper. In the cooling step, the temperature of the paper is reduced, e.g. below ambient temperature or below the dew point of a liquid-saturated gas mass applied in the liquid-application step. The gas may be ambient air and the liquid water. Control means monitor the amount of liquid applied to the paper by means of measuring the relative humidity of the air, the absolute humidity of the paper, the temperature of the device where the liquid is applied and the temperature of the paper. The invention also comprises a device for applying the method and it may be applied to paper emerging from a printer, e.g. a digital printer.

Description

technical field [0001] The present invention relates to methods and apparatus for conditioning paper. Background technique [0002] In particular, the present invention relates to methods and apparatus for conditioning paper in printing systems, and more particularly, the present invention relates to methods and apparatus for conditioning paper in digital printing systems, although the invention is not necessarily limited to this application. [0003] High-volume printing systems based on electronic technology (digital printing) arise from the need of companies to be able to print a large number of private documents in a short time. These systems have been enhanced in capacity and print quality through the use of roll-fed printers to convert digital files into individual printed files, and have evolved into graphics products, enabling these new printing systems to enter new markets with high growth potential. This technology makes it possible to print smaller-scale product...
