Flexographic Printer
The Basics A flexographic printer follows a routine sequence of steps to create a final product. The paper is fed though the printer from a roll and is then pulled through a series of print stations. Flexographic printers use four shades of color to create images: cyan, yellow, magenta, and black. The process can be broken down into four primary steps. Image Preparation This step begins with obtaining a design. The design can be mechanical or electronically produced. These images are then made into positive or negative films to be placed on the plate. Plate Making The next step involves creating a plate for the pcmd flexographic printers. First an engraving is made and then placed in a mold press. This method is used to create relief plates. These plates have the image raised and are attached to a roller so ink can be applied. Plates can be created by a photomechanical, photochemical or laser engraving process. Printing Presses There are five types of presses for the best flexographic printers. All types use a plate cylinder to roll ink onto the plate and ink pan. This cylinder is often called a anilox roll. Ink All flexographic printers, including used flexographic printer use ink that is fast drying and is not very viscous. The inks are applied to surfaces and are designed to solidify when the solvents are removed. The solvents are generally removed by heat, unless a UV curable ink is used, which has fewer solvents. Finishing Once the substrate is done with the printing process it can be finished in any number of ways. For example, it may be folded, binded, coated, cut, or any combination of the operations. Applications Because a flexographic printer can print on many types of substrates it has a wide variety of applications. Some flexographic printer’s specialize in publication materials. They create newspapers, catalogs, comics, and directories. Other cheap flexographic printers concentrate on packaging. They make labels, packaging materials and folding cartons. These printers also commonly print envelops, food and candy wrappers, adhesive tapes, plastic bags, disposable cups, paper sacks, and milk cartons. There are even flexographic printers for diapers. Flexography is a popular printing process that continues to grow.
