Embodiment Construction

[0041] In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustration various examples in which the invention may be practiced. In this regard, directional terms (eg, "top", "bottom", "front", "rear", "front", "rear", etc.) are used with reference to the orientation of the figures being described. Because the disclosed components can be positioned in a variety of different orientations, the directional terminology is used for purposes of explanation and not limitation. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. Accordingly, the following detailed description is not to be taken in a limiting sense, and the scope of the invention is defined by the appended claims.

Abstract

A printing method and system includes a printhead (101) configured to eject a fixer fluid. The controller (10) is operatively connected to the printhead and is configured to control the printhead to apply the fixer fluid to the print area (114) in a pattern to form a patch (214, 224) having a predetermined area free of the fixer fluid .

Description

technical field [0001] The present invention relates to the field of printing, in particular, to a printing system. Background technique [0002] Some printing systems use a fixer fluid, which can be used to pre-treat print media. For example, inkjet printers form printed images by printing a pattern of individual dots at specific locations in a defined array for the print medium. The locations are conveniently visualized as small dots in a rectangular array. The locations are sometimes point locations, point locations, or pixels. Thus, the printing operation can be viewed as filling a pattern of dots of position with dots of ink. [0003] Fixer fluids are sometimes used to pre-treat print media to address coalescence, bleed, or other similar defects that are characterized by ink or pigment transfer across the print surface. Pretreatment fluids are often applied as a consistent layer prior to printing using common application methods, including roll coating of the pretre...
