Abstract
The utility model discloses a kind of intaglio printing roller, including roller body and the main shaft stretching out roller body two ends, described main shaft and this body by integral forming of roller, the outer peripheral face of described roller body is provided with several ink cells, and the middle part of each ink cell is provided with integrated cylinder at the bottom of and ink cell.This utility model sets up the cylinder at middle part in original ink cell structure, and the mid portion solving ink contained by ink cell contacts the problem that ink site that is abundant not as surrounding and that be transferred out reduces from the ink cell that depth ratio is shallower with printable fabric.
Description
Technical field
This utility model relates to a kind of intaglio printing roller, particularly relates to the printing roller of the shallower ink cell of the degree of depth on outer peripheral face.
Background technology
Intaglio printing is compared with relief printing plate, lithographic plate, and it is ink cell that intaglio plate preserves and transmit the carrier of ink.Owing to the ink volume of ink cell can be different, then the quantity of ink transmitted is also the most different, and therefore, the printing of intaglio printing has that layer of ink is abundant, bright in luster, clear layer abundant and the feature such as strong sense of reality, occupies the most important position in packages printing.The quality of printing and ink transfer situation have much relations, for the ink cell that depth ratio is shallower, the ink site being transferred out reduces, the such as site of the ink cell degree of depth 14 μm reduces, especially in high light part, illustrate that intaglio printing height light step turns shifting bad, reason is that ink cell is shallow, corresponding they the ink cell degree of depth and aperture area less, and the ink bottom the taper ink cell of carved intaglio is difficult to be transferred out, the especially mid portion of ink contained by ink cell, middle part and printable fabric instantaneous touch when ink transfer, not as surrounding contact abundant, so having occurred as soon as, from the ink site that the ink cell that depth ratio is shallower is transferred out, the phenomenon reduced.
A kind of theory is had to think: to be due to capillarity, i.e. when paper (or other printable fabrics) separates with photogravure roller, by means of capillarity attraction, ink in ink cell is removed and is attached to above, forme is the least with the gap of stock, capillarity suction is the biggest, ink transfer amount is the biggest, and the aperture area of shallower their ink cell of ink cell of depth ratio is smaller, so capillarity attraction of forme and stock is the least, is therefore easy to the situation that the ink site being transferred out reduces occur.
Utility model content
This utility model mainly solves the technical problem that and is, it is provided that a kind of shallow ink cell intaglio printing roller, the ink site that it is transferred out will not reduce.
This utility model solves its technical problem and be the technical scheme is that a kind of intaglio printing roller, including roller body and the main shaft stretching out roller body two ends, described main shaft and this body by integral forming of roller, the outer peripheral face of described roller body is provided with several ink cells, and the middle part of each ink cell is provided with integrated cylinder at the bottom of and ink cell.After cylinder is set up at middle part, change the ink level of original concave downward, although ink level is still concave downward, but the setting due to mediate cylindrical, concave downward degree is reduced, the abundant degree that when this can be effectively improved ink transfer, middle part contacts with printable fabric, can be prevented effectively from the situation about reducing of the ink site being transferred out from the ink cell that depth ratio is shallower；And reduce the gap of forme and stock to a certain extent, improve capillarity suction, increase ink transfer amount.
As the further improvement of this utility model a kind of intaglio printing roller, cylindrical height is slightly below the height of ink cell mouth.Such setting not only makes the recessed degree of ink level reduce, moreover it is possible to ensures the abundance of mid portion ink, greatly avoids the situation about reducing of the ink site being transferred out from the ink cell that depth ratio is shallower.
As the further improvement of this utility model a kind of intaglio printing roller, ink cell is reverse taper shape or basin shape.Using general ink cell form, in the most general ink cell structure, technological transformation is easy, sets up mediate cylindrical.
As the further improvement of this utility model a kind of intaglio printing roller, ink cell inwall one layer of oleophobic coating of coating.Such setting makes ink in ink cell die down with the adhesion of ink cell, ink in ink cell has the trend departing from ink cell, once stock presses ink and i.e. possesses the biggest and stock absorption trend, increase the trend of ink transfer, improve the transfer amount of ink, even shallow ink cell is without worrying that the ink bottom taper ink cell is difficult to be transferred out.
As the further improvement of this utility model a kind of intaglio printing roller, cylindrical end face one layer of oleophobic coating of coating.Such transfer amount being disposed to improve the mid portion of ink contained by ink cell further, itself is for shallow ink cell, owing to the ink cell degree of depth and aperture area are less, ink bottom taper ink cell is difficult to be transferred out, the mid portion of ink contained by ink cell is more difficult to, middle part and printable fabric instantaneous touch when ink transfer, not as surrounding contact abundant, so having occurred as soon as, from the ink site that the ink cell that depth ratio is shallower is transferred out, the phenomenon reduced, and cylinder is set by the middle of ink cell, and end face arranges oleophobic coating, the ink above it is made to have the trend departing from ink cell, add the ability of the transfer tendency of middle ink, and owing to adding cylinder, reduce the difference of the exposure level of conventional mid portion ink and circumferential section ink, the most also the situation that site ink reduces can be reduced.
As the further improvement of this utility model a kind of intaglio printing roller, it is additionally provided with integrated cylinder at the bottom of several and ink cell arranged around described cylinder circular array.Such setting makes an original recessed ink level become multiple recessed ink level, but recessed degree is greatly reduced, recessed height is greatly reduced, the abundant degree that when being effectively improved ink transfer, middle part contacts with printable fabric, can be prevented effectively from the situation about reducing of the ink site being transferred out from the ink cell that depth ratio is shallower；And reduce the gap of forme and stock to a certain extent, improve capillarity suction, increase ink transfer amount, and the mode arranged of several cylinder uniform intervals does not interferes with the transfer case of the ink on the circumference of its circle formed yet.
The abundant degree that when this utility model is effectively improved ink transfer, middle part contacts with printable fabric, add the capillarity attraction between forme and stock, improve the transfer amount of ink, the ink site being transferred out will not reduce, and technological transformation is easy, with low cost.
