Description
Technical Field
The invention relates to the technical field of product printing processes and equipment, in particular to a method for changing gravure pearlescent ink into online flexo printing.
Background
With the continuous development of the printing industry, various printing modes and printing processes are developed, and a plurality of new elements are added to printing equipment, printing processes and the like on the basis of the tradition. The original gravure and flexo printing belong to two completely different printing modes, through continuous development, the two modes with different attributes are softened, the finally achieved effect is the same, and meanwhile, the cost can be saved. For the printing product with the pearly luster base, the spreading printing of pearly luster ink is required before the printing and coloring, and then the coloring printing is carried out. Because the spreading printing of the pearl ink belongs to gravure printing, and the subsequent printing belongs to offset printing, different printing modes must be finished by working procedures, so that the production of single working procedure and multiple working procedures inevitably causes various cost increases, and the rejection rate is increased. For the flat paper printing, the printing speed has obvious difference, the production efficiency of the single intaglio printing is about 5000 sheets/h, the printing production efficiency of the offset printing is about 10000 sheets/h, and the difference is two times of the production efficiency, so that the offset printing cannot be recognized by production enterprises.
Therefore, we propose a method of changing gravure pearlescent ink into line flexo printing so as to solve the problems mentioned above.

s3: selecting an anilox roller: firstly, estimating and selecting anilox rollers with the number of lines per inch to meet the ink amount of a print according to the inking areas of various colors of pictures and texts of a printed matter by daily experience, and secondly, observing the hue, saturation and the like of each color print in the primary plate correcting overprinting process according to the ink absorption amount of a printing material, and selecting a proper anilox roller;
s4: replacing the gravure printing unit: because the spreading printing of the pearl ink belongs to gravure printing, and the subsequent printing belongs to offset printing, different printing modes must be finished by different processes, the production of a single process and multiple processes inevitably causes various cost increases, and the rejection rate is increased, so that an intaglio printing unit on a printing unit is replaced by a flexographic printing unit;
s5: adding an offset printing unit: an offset printing unit which works in cooperation with the flexographic printing unit is added on the flexographic printing unit of the printing equipment, and transfer printing is carried out through the offset printing unit, so that the production efficiency and the yield can be improved;
s6: printing operation: the method comprises the following steps of firstly carrying out coil feeding and paper feeding, then carrying out adjustment and deviation rectification on a printing material to ensure subsequent normal feeding, then adjusting the pressure between a printing plate roller and an anilox roller and an offset printing roller to enable the three rollers to carry out printing normally, then carrying out the inking of pearlescent ink, and then carrying out the processes of impressing, drying, die cutting, slitting, rolling and the like to finish the flexographic printing.
Preferably, the method for supporting the printing plate by heating and pressing the natural rubber or synthetic rubber material using the mold includes the steps of firstly making a metal original plate, i.e. a metal relief plate, then making a resin intaglio plate (a casting template) by using a thermosetting resin (such as a phenolic resin), finally making a rubber original plate by heating and pressing on a hot press, and then grinding the rubber original plate to form the flexographic printing plate.
Preferably, the technology for forming the plate graph and text by utilizing the photopolymerization process of the monomer and the polymer comprises the steps of firstly forming a solid photosensitive resin plate by a protective film, a photosensitive resin layer, an adhesive layer, a plate base and a protective layer, and then completing the manufacturing of the photosensitive resin flexible plate through negative preparation, back pre-exposure and main exposure processes.
Preferably, the anilox roller is matched with the flexo pearl ink.
Preferably, the pearlescent ink is firstly conducted to an anilox roller in an ink groove, the pearlescent ink is transferred to a flexographic roller by the anilox roller, a printing pattern is transferred to an offset printing roller by the flexographic roller, and finally the pattern is printed on a printing stock by the offset printing roller.
Compared with the prior art, the invention has the beneficial effects that: the method for changing gravure pearlescent ink into connection line flexo printing changes the gravure printing mode into the flexo printing mode, thereby changing the mode that the gravure printing and offset printing are completed in different working procedures in the working process, for the flat paper printing, the printing speed has obvious difference, the production efficiency of single gravure printing is about 5000 sheets/h, the printing production efficiency of offset printing is about 10000 sheets/h, the difference is two times of production efficiency, and the production efficiency can not be accepted by production type enterprises, therefore, the connection line flexo printing production is completed by combining the flexo printing and the offset printing, the cost can be greatly saved by adjusting the printing ink and changing and combining the printing mode, and the production efficiency and the yield are improved.
