Detailed description of the invention
< flexible printing plate >
The feature of flexible printing plate of the present invention is: be formed as that one side is printing surface, opposing face is towards the tabular of the installed surface of plate cylinder, described installed surface is the arithmetic average roughness Ra of roughness curve is more than 0.02 μm, less than 0.06 μm, maximum height roughness Rz is more than 0.25 μm, less than 1.60 μm, and 10 mean roughness Rz
jISit is the matsurface of more than 0.20 μm, less than 0.80 μm.
The installed surface connected with plate cylinder is set to even surface by existing flexible printing plate, be close contact on the surface of the plate cylinder being set to even surface equally strongly, therefore as noted, even if terminate along with printing and remove the power of shear direction, extend and also do not remove and accumulate, thus produce position skew.
If in contrast, utilize flexible printing plate of the present invention, then by the installed surface connected with plate cylinder being set to the matsurface meeting described characteristic, the contiguity power relative to plate cylinder surface can be lowered, moderately easily can slide relative to this surface.Therefore, when terminating along with printing and remove the power of shear direction, the extension of flexible printing plate can be removed, and can prevent this extension from accumulating and produce position skew.
And, flexible printing plate of the present invention, except being set to by installed surface except described matsurface, can be formed, without the need to metal base etc. in the same manner as existing flexible printing plate, in addition by being installed on plate cylinder surface with previously same installation method, without the need to using two-sided tape etc. and fixing.
Therefore, even if large areaization also can easily be carried out relative to the installation of plate cylinder, dismounting, and the flatness of printing surface when being installed on plate cylinder surface is excellent, is therefore suitable for the printing of liquid crystal orienting film used for liquid crystal display element.
In addition, in the present invention, by the arithmetic average roughness Ra of roughness curve, a maximum height roughness Rz and ten mean roughness Rz
jISbeing defined in illustrated scope respectively is above due to following reason.
Namely, when any one not enough respective scope of described 3 kinds of roughness, the matsurfaceization of installed surface all can be insufficient, and the contiguity power for plate cylinder surface lowers, and fails to obtain the effect of moderately easily sliding for this surface.Therefore, when repeatedly printing, extending and accumulated and produce position skew.
On the other hand, when 3 kinds of roughness any a kind exceed respective scope, the matsurfaceization of installed surface all can be superfluous, and the contiguity power for plate cylinder surface becomes too low, too easily slides for this surface.Therefore, becoming easy extension when applying the power of shear direction when printing, particularly becoming the skew easily producing the spacing caused because printed patterns entirety extends.
Relative to this, by 3 kinds of roughness are all adjusted in respective scope, can bright making like that moderately lower relative to the contiguity power on plate cylinder surface as noted earlier, moderately easily slide for this surface, be also difficult to offset in the generation position, surface of plate cylinder even if can realize repeatedly printing.
