Description
Technical field
The patent of invention is related to a kind of intaglio printing and digital ink-jet printed innovative combination, and the combined application is in reel
The printing stamp of paper, film.The machine incorporates the advantages of traditional intaglio printing and modern digital ink-jet printing, also mutually more
The shortcoming for having mended gravure sum number print becomes revolutionary upgrading again and leading hair in textile industry transfer printing paper field
Exhibition.
Background technique
The calico paper in the field all uses intaglio press to complete before, and the flower-shape after print on calico paper passes through hot roller hair
Flower-shape on paper is transferred on cloth by blanket transfer, and figured cloth produces.Paper is just used as an instrumentality.With the development of technology
It develops, digital ink-jet printing technology is trend of the times, and intaglio press faces unfrequented largely reduce.The two compares, and still has each
There is feature, but digital spray printing advantages for development are huge.First from the point of view of advantage comparison：Digital printing, which has, does not need plate-making saving system
Version cost, using computer input method can, personalized strong, output is fast, three-dimensional sense is strong, small, the adaptation pattern variety that occupies workshop and
The small lot production advantage.The sector solves batch production, the big single amount production mesh of single variety using more units substantially at present
It is preceding also to be produced by the way of intaglio printing.Intaglio printing has that speed is fast, yield is big, printing cost is low, color difference is stable.The two
Level caused by print principle difference and aesthetics all have very big advantage.The two compares there is also shortcoming simultaneously, counts
Code：Speed is slow, yield is small, and ink is at high cost, and color difference is big, cannot repeat double exposure, is not suitable with big single amount production, and product cost is high.
Gravure：Plate-making and management cost are big, and production workshop is big, and less than number, flower-shape designs output for sample and small single amount pattern variety
Process is some etc. slowly.
Defect existing for both complementary mode of printings of the invention, the effect number being unable to reach such as gravure can reach
It arrives；Conversely, what number can not be accomplished, gravure may be implemented.Therefore, which has gathered the two advantage, while making up the two not
A new generation's product leading in the industry of foot.
Summary of the invention
