Description
Technical field
The present invention relates to printing technologies, and in particular to a kind of method for platemaking of belling version.
Background technique
Belling is the technique that raised picture and text are extruded on the predetermined position of printed matter, to enhance the three-dimensional sense of picture and text.Belling
Device generally include intaglio plate, relief printing plate and can control intaglio plate and relief printing plate folding opening and closing control mechanism, intaglio plate include top plate and
At least one intaglio plate unit on top plate, relief printing plate include bottom plate and at least one relief printing plate unit set on the bottom plate, relief printing plate
Unit is identical as intaglio plate element number and corresponds, the raised picture and text on relief printing plate unit and the concave picture and text phase on intaglio plate unit
Matching.When the printed matter of belling enters between intaglio plate and relief printing plate, opening and closing control mechanism presses intaglio plate and relief printing plate, at this time
Each relief printing plate unit and corresponding intaglio plate unit matching carry out belling operation on the corresponding position of printed matter, keep printed matter corresponding
Position protrusion, form raised picture and text.
Currently, intaglio plate unit generally use metal plate (general processing picture and text are simple, embossing product quantity less can be with
Select photo zincography；Processing picture and text are complicated, embossing product quantity can select greatly copperplate or steel version), fabrication processing packet
Include version base preparation (version base prepares to include the processing such as gravure materials selection, version base surface inspection and cleaning), original copy preparation and transfer
The step such as (original copy prepares and transfer can directly be handled using computer, taking a picture teds, turns over the methods of sample by hand) and printing plate production
Suddenly.Printing plate production can be using different methods such as etch, engraving method and synthesis.Etch is to make version using corrosive liquid
Chemical change occurs for material surface, to form the required concave picture and text structure of printed matter coining.The picture and text that chemical corrosion method is formed
It is recessed shallower, and entire space of a whole page cup depth is consistent, therefore expressive ability is limited.The concentration, temperature of corrosive liquid in chemical corrosion method,
The factors such as the degree of fatigue of etching time and corrosive liquid, stirring have certain influence, therefore corrosion process technique to plate quality
Condition should strict control.Engraving method is by manually or mechanically by means of dedicated tool, requiring for plate to be engraved as according to picture and text
Meet the printing plate of coining processing request, this method large labor intensity, the plate-making period is long, many and diverse printing plate engraving of some picture and text, no
Only technical difficulty is big, and operator is required to have certain fine arts, printing and engraving grounding in basic skills.Synthesis is rotten using chemistry first
Printing plate depressed section is eroded to certain depth by erosion method, on this basis, then it is bright not enough to profile on printing plate using engraving method
Aobvious, picture and text cup depth is also not up to printed matter protrusion and requires or retrofit part is needed to be further processed again, obtains it
Obtain the effect of engraving version.
The production of relief printing plate unit usually carries out after intaglio plate unit is made, the picture and text on relief printing plate unit and intaglio plate unit phase
Instead.The production method of relief printing plate unit is at present frequently with gypsum relief printing plate, high molecular material relief printing plate etc..
Gypsum relief printing plate, main making material are that (land plaster is the plaster of paris to land plaster, is had after the mixed water of powder plastic
Property, and harden fast, and but quality is very crisp after drying, and compressive resistance is not high), other auxiliary materials include gum arabic, paste etc..
The production method of gypsum punch-pin is: the intaglio plate made being sticked on the metal base plate of spreader bar, after smoothing plank, by manila board
It is sticked on coining plate, land plaster is then reconciled into pulp with gummy liquid, and quickly calcium plaster is coated on and imprints lithographic plate table
On the manila board in face；After shakeouing, one layer of thin paper (such as flat envelope, wild goose mulberry paper) is first covered, then cover layer of plastic film, to prevent
Calcium plaster is embedded in cavity plate decorative pattern, in this way, gypsum layer surface just forms convex picture and text after pressurized.Pressurization is carried out in two steps, the
When primary coining, pressure is not answered excessive, as long as showing slightly shadow, main purpose is to obtain apparent picture and text in gypsum layer surface
Mark, using the reference as the inspection space of a whole page, adjustment pressure；Then second of coining is carried out again, and first cushioning one is opened behind intaglio plate
Thicker white board, when gypsic horizon close to it is dry when imprint up again, at this point, gypsic horizon surface picture and text impression will be ten clearly demarcated
It is aobvious.
High molecular material relief printing plate is formed generally using thermoplastic as substrate using single cavity plate mould pressing method.Single cavity plate
Compression molding is after being overlapped prefabricated panels with cavity plate, and in Special forming machine, heated, pressurization makes its molding.Its technique mistake
Journey is as follows: version base surface clean → molding surface coating release agent → frames up upper machine → adjustment temperature, pressure → pressurization into mould → cold
But demould → cut finishing → finished product relief printing plate.The selection of high molecular material relief printing plate, substrate is particularly significant, generally substrate is required to want
There is good mechanical strength, molding quickly, conveniently, and requires molding technological condition not harsh.Relief printing plate after molding is with generally
Double-sided adhesive or general purpose adhesive can obtain enough adjustment of the printing plate fastness.
The technique of above-mentioned production intaglio plate unit and relief printing plate unit is generally complex cumbersome, spends the time longer, production
Higher cost.After making intaglio plate unit and relief printing plate unit, then each intaglio plate unit is fixedly installed on top plate to (above-mentioned top plate is logical
It is multiple for installing the plate of the mounting hole of limit bolt or limited block frequently with being evenly equipped in cellular board, that is, plate face, it is inserted by limiting
Intaglio plate unit is fixedly mounted on top plate by pin or limited block, and limits the position of intaglio plate unit), by the fixed peace of each relief printing plate unit
It is attached on bottom plate, since picture and text concave on each intaglio plate unit must be accurately corresponding with picture and text raised on each relief printing plate unit,
The raised picture and text of satisfactory quality can be formed on the corresponding position of printed matter, therefore, each intaglio plate unit is being installed to top
