The advantages of gravure

Gravure is also called rotogravure. Like engraving, gravure is a form of gravure that produces fine, detailed pattes. Like flexo, gravure is often used for high-volume printing on packaging, wallpaper, and gift wrapping. , although less common, gravure can also be used to print magazines, greeting cards and mass advertising pieces. is a durable, high-speed, high-quality printing method for CMYK printing, where each ink color is applied by its own cylinder with a drying step in between. In gravure printing, the patte of each unit is acid-etched for each color on a cylindrical surface of a metal cylinder. Like a gravure or letterpress press, these units are recessed into cylinders where the printed image is lifted or similar to offset printing, with the image level with the plate. Cylinders were etched with cells of different depths. These cells remain in the ink transferred to the substrate.

The size of the cells must be precise, as darker cells produce more intense colors than lighter cells. The cells are filled with ink, and the non-printed parts of the plate or cylinder are wiped off or scraped off the ink. Then, the paper or another substrate is pressed into the ink cylinder on a rotary press, and the image is transferred directly to the paper, unlike in offset printing using an intermediate cylinder. The engraved cylinder is partially immersed in the ink fountain, where it picks up ink to fill the recessed battery with each revolution of the press.

Gravure printing has many advantages: 1. Fewer variables to control than other printing processes, ensuring more consistent print quality during operation. 2. Gravure printing standing pouch bag   provides "consistent colors, even if the run includes millions of copies." 3. Gravure printing is a direct printing process, the image on the cylinder is directly printed onto the substrate, resulting in better ink layout and more faithful image rendering. 4. Color diversity, the image data wrapped around the cylinder can be continuous, so there is no panel seam display, such as wallpaper or gift wrapping.

5. Wide adaptability, wide range of substrates, publication printing: very thin paper or coated paper. Packaging Printing: Cardboard, Plastic Film, Aluminum Foil, Laminate, Vinyl, Non-porous Materials.

6. There is a lot of ink adhesion. The depth and size of the engraved cells determine the amount of ink that can be placed on the substrate. Gravure printing can produce more ink than other processes.

7. High productivity, gravure printing machine runs at high production speed: 3000-3300 feet per minute.

8. The printing plate roller is very durable. It is common to print 2 million to 3 million from one plate roll set. Diamond cutting tools (engraving heads) can cut at 10,000 units per second. From this point of view, gravure printing is indispensable in our lives, and it is also a manifestation of the continuous optimization of printing methods in the new era.
