Problems solved by technology

In addition, when double-sided printing is performed, usually, after printing on one side (front side) is completed, printing is performed on the other side (back side); Deviation in size and position of images printed on front and back (i.e., registration mismatch between front and back)
[0003] Not only double-sided printing, but also in the case of single-sided printing, there is a problem of deterioration in printing quality due to warping or wrinkling caused by paper deformation as described above
In addition, there is a problem of causing negative effects on subsequent processing steps performed after the printing step, such as the binding process
[0004] Japanese Patent Application Laid-Open Document No. 2001-063019 discloses a printing device which is constructed to solve the problem that when performing double-sided printing, if the drying of the front side is insufficient, the image will be scratched when it rubs against guides and the like. hurt
[0008] Therefore, if an arrangement is adopted in which the top plate is placed above the printed stack of sheets, and air is blown uniformly from the side ends to the stack of sheets, some of the sheets on the upper side of the stack tend to Moves up near the roof and air flow becomes poor
In addition, the posture of the paper becomes unstable during the air blowing process, especially in the case of thin-layer paper, problems such as folding are prone to occur

Abstract

The invention relates to a printing paper seasoning apparatus, a method therefor and an inkjet recording apparatus, wherein sheets of paper are placed in a stack in a paper accommodating section.A direction to which convex sides of curled sheets face is taken as a curl direction.An air flow is controlled in such a manner that during an initial period of an air blowing, the air flow supplied to one of the upper and lower portions of the paper accommodating section on a side opposite from the curl direction is greater than the air flow supplied to the other of the upper and lower portions on a side of the curl direction.During a latter period of the air blowing, the air flow supplied to the one of the upper and lower portions on the side opposite from the curl direction is reduced.The air flow supplied to the other on the side of the curl direction is increased.

Description

technical field [0001] The present invention relates to a printing paper seasoning device and method and an inkjet recording device, and more particularly to a seasoning technique that reduces the expansion / shrinkage and out of shape. Background technique [0002] In printing systems, paper expands and contracts shortly after ink has been deposited on the paper due to differences in moisture content due to ink shades (ie, different ink volumes) in the image areas. This problem is especially pronounced in systems that use water-based inks to print on regular paper. In addition, when double-sided printing is performed, usually, after printing on one side (front side) is completed, printing is performed on the other side (back side); Deviation in size and position of the images printed on the front and back (ie, misregistration between the front and back). [0003] Not only double-sided printing, but also in the case of single-sided printing, there is a problem of deteriorat...
