About two-thirds of the world’s printed fabric market is accounted by rotary printing technology. A cylindrical screen with perforations is used to apply colour in a continuous printing process. The print media is pushed through the screen and onto the fabric by a squeegee device inside the screen as it rotates.
For decades, textile printers have been able to increase efficiency, production, and profitability through the use of rotary screen fabric printing. It’s easy to see how a rotary textile fabric printing machine can enable you to boost your productivity.
Rotary presses are made of two cylinders that rotate in opposite directions: the plate cylinder has curved printing plates connected to its surface, and the impression cylinder presses the paper against the inked plates as it travels between them.
A rotary printing press produces what kind of print?
The images to be printed are bent around a cylinder in a printing press known as a rotary printing press. Paper, cardboard, and plastic are just a few of the many substrates that can be used for printing.
Types of Rotary Ink
The ink used for letterpress printing on books, magazines, and other printed materials is known as this sort of printing ink. Rotating ink is available in book and heatset forms. The surface hardness (and other features) of the book paper on which it is to be printed affect the tack and consistency of book inks, which are fluid in nature. For letterpress printing, heatset inks are made from a combination of synthetic resins and low-volatility hydrocarbon solvents with boiling points between 400°F and 500°F, which evaporate rapidly.
Working
Using a simple two-color rotary printing machine, two sequential plate cylinders are used, each with a different typographic shape and inking mechanism. As the paper travels through the press, it obtains two separate imprints of two different colours on the same side of the sheet of paper.
Using varied combinations and successions of printing plates and cylinders, a rotary printing press can print in three, four, or even five colours on a sheet of paper.
Highly automated rotary presses are capable of producing extraordinarily high volumes of product at a rapid pace.
The cylinders of these machines are large enough to hold two or more plates, so that each revolution of the cylinder prints two or more copies of the same page.
Brochure printing can be done in-house by many companies because the installation costs are relatively modest. The pad printing method is also quite simple to master, as the equipment does not necessitate a large amount of floor space.
The following are some of the most important aspects of the
• Method of printing in which the ink is applied continuously
Long runs of the same pattern, complicated patterns, surface treatments such as glitter, glue, sequins, pearlescent, metallic, 3D particles, and rotating screens with perforations are all good candidates for this method.
Advantages
Versatile design and special effects possibilities • Fastest printing process • Quick changeover of patterns
• Low-cost for large-scale manufacture
Disadvantages
Printing at a higher speed might produce registration issues, making it unsuitable for fine detail printing and therefore not economically viable for small runs.
