Abstract
One kind freezing off type offset printing coating paper, wherein has pigment application layer in the one or two sides of body paper, grammes per square metre is 60~200g/m2, above-mentioned pigment application layer includes 0.95 μm of calcium carbonate below of average grain diameter, and the coating weight of above-mentioned pigment application layer is every single side 5g/m2More than.The present invention provides one kind and freezes off type offset printing coating paper, and excellent printing characteristic is presented and is not likely to produce fold.
Description
Technical field
The present invention relates to freeze off type offset printing coating paper.
Background technique
Paper for newspapers is usually by without the newspaper press of drying device and in the way of using infiltration dry (freezing off)
Newspaper ink special is printed.In the past, as paper for newspapers, it is known that without the uncoated paper of pigment application layer, micro- coating
Paper (patent document 1: Japanese Unexamined Patent Publication 2003-286686).However, implementing to print made of printing to these paper using newspaper press
Brush object is compared with implementing printed article made of printing to coating paper using the Commercial printers for having ink drying apparatus, drying property
Difference, print gloss is low, poor appearance.
On the other hand, in rotary press, if the surplus of paper tails off, in order to avoid operating efficiency reduction and
Moment carries out splicing operation automatically in the case where not stopping rotary press.Be carried out at high speed operating rotary press in, due to splicing
When impact it is big and paper for newspapers occur and lead to the problem of fold.Therefore, it is proposed to a kind of method (patent of pre- anti-fold generation

The processing that soft press-polishing machine, supercalender, gloss calender, hot pressing ray machine, sucked type calender carry out.
(4) characteristic of type offset printing coating paper is freezed off
1) grammes per square metre
In general, being as follows by the grade separation of pigment coated paper: 80~150g/m2The pigment in the grammes per square metre area of degree applies
Cloth paper is A2 grades, 60~80g/m2The pigment coated paper in the grammes per square metre area of degree is A3 grades, in conjunction with purposes paper selected to use.This hair
The bright grammes per square metre for freezing off type offset printing coating paper is 60~200g/m2.Spooling length is short if grammes per square metre is excessively high, utilizes rotary press
Paper replacement frequency it is high, thus the risk of disconnected paper is got higher.In addition, the rigidity due to paper is high, so winding paper is difficult to be utilized
It is printed, and the risk for generating the mechanical breakdown to become larger with the thickness of paper difference of common paper for newspapers increases.On the other hand, such as
Fruit grammes per square metre is too low, then fold when splicing can not be inhibited to generate.According to the above, the lower limit value of grammes per square metre is preferably 60g/m2More than,
More preferably 70g/m2More than.The upper limit value of grammes per square metre is preferably 180g/m2Hereinafter, more preferably 170g/m2Below.Of the invention
The grammes per square metre for freezing off type offset printing coating paper is more preferably A2 grades of 80g/m2~150g/m2.A2 grade of the invention freezes off type
Fold of the offset printing coating paper in printing generates few, available further excellent print gloss, image distinctiveness.Grammes per square metre can
It is measured based on JIS P8124.
2) winding diameter
It is as newspaper printing with winding paper using the winding paper that type offset printing uses coating paper to wind and obtain that freezes off of the invention
Useful, winding diameter is preferably 850~1200mm.Winding diameter refers to the diameter of winding paper (roller), using formula below,
It is found out by calculating:
D=(4tL/ π+d2)1/2×1000
D: winding diameter (mm), t: thickness of paper (m), L: spooling length (m), d: the diameter (m) of mandrel
If winding diameter is less than lower limit value, spooling length shortens, and splicing number when printing becomes more, operating efficiency etc.
It can reduce.On the other hand, the printing machine reduced if winding diameter is more than upper limit value there are transfer efficiency can not corresponding feelings
Condition.From this viewpoint, the lower limit value of winding diameter is preferably 890mm or more, and more preferably 900 or more.Winding diameter it is upper
Limit value is preferably 1150mm hereinafter, further preferably 1100mm or less.
3) density
The density for freezing off type offset printing coating paper of the invention is preferably 0.8~1.3g/cm3.If density is more than the upper limit
Value, then the hardness of paper can reduce.In addition, need to reduce coating weight to be set as being less than lower limit value, therefore as a result, ink
Drying property, print gloss reduce, and there is the case where can not obtaining effect of the invention.From this viewpoint, the lower limit value of density
Preferably 0.8g/cm3More than, more preferably 0.9g/cm3More than.The upper limit value of density is preferably 1.3g/cm3Hereinafter, more preferably
For 1.2g/cm3Below.
4) blank sheet of paper glossiness
The blank sheet of paper glossiness for freezing off type offset printing coating paper of the invention is preferably 25~80%.Matt is needed in printed article
It is preferably 25~50% in the case where the quality of style, in the case where printed article needs the quality of bright style preferably 50~
80%.Matt style freezes off type offset printing coating paper without calender processing, or even if carries out the processing also due to slight
And the reduction for freezing off the density of type offset printing coating paper is few, and can inhibit fold generation, therefore it is preferred that.In addition, blank sheet of paper glossiness 25
~50% matt style freeze off type offset printing coating paper printing when drying property it is also excellent.Blank sheet of paper glossiness can be based on
JIS P8142 and measure.
5) ISO whiteness
The ISO whiteness for freezing off type offset printing coating paper of the invention is preferably 80% or more, and more preferably 82% or more.
By making ISO whiteness be in the range, to can get distinct image when carrying out newspaper rotary printing.ISO whiteness
It can be measured based on JIS P8148.
6) bending stiffness
The ISO bending stiffness in the direction MD for freezing off type offset printing coating paper of the invention is preferably 150 μ Nm2/ m or more, more
Preferably 200 μ Nm2/ m or more.In addition, the ISO bending stiffness in the direction CD is preferably 100 μ Nm2/ m or more, more preferably 120 μ
Nm2/ m or more.Fold when being able to suppress splicing and making ISO bending stiffness be in the range generates.In addition, rigidity is high
One side is few the case where paper bending due to self weight when newspaper is unfolded, and becomes the newspaper that readability easily turns over.ISO bending stiffness can be based on
ISO2493 and measure.
7) print gloss
Print of the type offset printing coating paper using newspaper printing (freezing off type) ink implementation printing when is freezed off to of the invention
Brush glossiness (it is blue: C, red: M) it is preferably 10~80%.It is being printed in the case where freezing off type offset printing coating paper of matt style
Under, preferably 15~55%, being printed in the case where freezing off type offset printing coating paper of bright style, preferably 55~
85%.By making, printing characteristic becomes good and print gloss is in the range.Print gloss can be based on JIS P81428
And it measures.In addition, the print gloss difference that the value obtained with subtracting blank sheet of paper glossiness from print gloss defines is preferably 5 points
More than, more preferably 8 points or more.Even if the type offset printing coating paper that freezes off of the invention uses the newspaper printing oil of osmosis type
Ink, print gloss is also high, therefore the images such as photo are distinct.
