Overview of gravure printing technology
talking about gravure printing, We seem to go back to the ancient times when hand engraving was used. Joepickard, chief economist of ISRI, said: "More rumors indicate that the ban may be more severe. Until the invention of chemical etching plate making process in the 16th century, so that the printing machine to plate making, gravure has been considered as an art form.
in 1875, the use of gelatin photosensitive materials made photographic plate making possible. Until 1930, the photographic concave printing process was only used in the publishing industry.
now, this technology is widely used in various fields, Print magazines, labels, gift packages, product catalogs, etc. It has become a mature printing process, which is widely used in long edition printing with fast speed and exquisite printing quality

due to the use of toluene in gravure printing, this has a great impact on the application of technology, but in the United States, this problem seems to be under control, because most American printers now use solvent recovery devices
types of gravure inks
in the field of gravure printing, you can find the fastest and widest printing machine in the whole printing world, with a speed of 3000 feet per minute
you can imagine that at such a speed, the ink must be instantly dried, so that the next color can be printed in time to avoid ghost phenomenon. This is why until today, almost only solvent based inks are used, mainly based on toluene

the regional distribution of the gravure market has shrinkage resistance due to the shapes of stiffeners, holes, bosses and engraving
the regional distribution of gravure printing machines has some historical and democratic factors
in the North American and European markets, more and more flexographic printing is used. Relatively speaking, gravure is only used for long-term printing, that is, the publishing industry
in Asia, gravure printing is widely used in medium-sized applications, such as packaging
