A printing system and method for improving ink absorption in a print substrate by preventing evaporation includes a conditioned transport module arranged for transporting a printed print substrate from a (conditioned) image formation module to a drying/fixation module. The transport module includes a control system configured for controlling the relative humidity inside the transport module to at least 50%.

Method of printing

A system and method for adding a print medium digitally to a print system are disclosed. The print system has a control unit for controlling a print job queue and print system parameters, a print engine, an input section, and a receiving section. The method includes receiving the print medium in the input section, loading a test job having prescribed print system parameters in the receiving section, printing a large number of prints of the test job to establish an unwanted deposit of marking material on the side of the stack, and establishing whether or not an unwanted marking material is deposited on a stack height side of the stack. If unwanted deposit is established, then printing a number of blank sheets of the same print medium, adjusting the print system parameters, and returning to printing. If no unwanted deposit is established, approving the use of the print medium.

Method for approving a new print medium for use in a print system

The present invention provides a method of optimizing the operating conditions for printing sheets, comprising the following steps: introducing a sheet into the printing system; treating the sheet by exposing the sheet to a physical operating condition of the printing system at a predetermined level; sensing a surface geometry of the exposed sheet to generate data representing a height map of the surface of the at least one exposed sheet for that predetermined level of that operating condition; and comparing the data to one another and/or a reference value to determine the suitable level of the least one physical operating condition. The invention further provides an apparatus optimizing the operating conditions for printing sheets.
