Types of Printing
The leaflet printing industry has been around for many years. In the 15th century, the invention of the printing press made it possible to print books in large quantities. Previously, books were copied one at a time. Although newspapers have shifted online, books still have a place in society. This article will discuss the different types of printing, including Offset lithography, Digital printing, Flexographic printing, and Woodblock printing.
Woodblock printing is a traditional art form that uses a wooden block to create a design. The block is inked with an oil-based ink and the paper is placed on top of it. It is then printed by hand using a rubbing tool or with a printing press. The ink is applied in layers, with the first layer sitting on top of the second. In Japanese woodblock printing, rice starch printing paste is used in place of oil-based ink. Humid paper is placed onto the block, and the block is rubbed down with a printing tool known as a baren.
Unlike traditional printing, woodblocks can produce multiple impressions. A single block can produce several different colors. In addition to this, multiple blocks can be used to produce the same design. For example, if a print is to be produced with multiple colours, a different woodblock may be carved for each successive colour.
Offset lithography printing works on a simple principle. It involves printing images on flat, dampened printing plates. The images are then transferred from the plates to the paper or rubber blanket. The process is different from gravure and letterpress printing. Offset lithography relies on water-based inks, which adhere to the image areas and not to the surrounding non-image areas.
Offset printing offers a high-quality print with an extremely fast turnaround time. The process consists of two parts: the pre-press stage, and the printing stage itself. The pre-press stage involves the breakup of the digital file into separate color separations. This is then laser etched onto decoded aluminum plates. The plates are then loaded into offset printing machines, which then use rollers to transfer the ink to the paper.
Flexographic printing is a technique for printing on a wide variety of substrates. It is not as volume-intensive as screen or gravure printing, and the ink used is less viscous. However, it has the benefit of being inexpensive, resilient, and easily producible. In addition, flexographic printing allows for the printing of non-porous materials.
Flexographic presses are used to print on a variety of materials, including uncoated and coated paper. They are also used to print on different types of plastics, non-woven fabrics, and foil. They can also be used to produce self-adhesive labels.
