Flexible printing may refer to: Sign printing, of vinyl banners; Flexography, a form of printing process which utilizes a flexible relief plate;
Flexography (often abbreviated to flexo) is a form of printing process which utilizes a flexible relief plate. It is essentially a modern version of letterpress, evolved with high speed rotary functionality, which can be used for printing on almost any type of substrate, including plastic, metallic films, cellophane, and paper.
The main types of flexographic ink are water based, [2] solvent and UV curable. [3] The printing surface (substrate type) dictates what ink type it is advisable to use.Each type of ink has its advantages and disadvantages, therefore the type of ink used in printing is determined by factors such as price, speed, and the use of the packaging (food, cleaning, or shopping bags).
The most commonly used material is a heavy weight vinyl known as PVC (polyvinyl chloride). The weights of the different banner substrates range from as light as 9 ounces per square yard (310 g/m 2) to as heavy as 22 oz/sq yd (750 g/m 2), and may be double- or single-sided.
Woodcut is a relief printing artistic technique in printmaking in which an image is carved into the surface of a block of wood, with the printing parts remaining level with the surface while the non-printing parts are removed, typically with gouges. The areas to show 'white' are cut away with a knife or chisel, leaving the characters or image ...
In gravure printing, the image is engraved onto a cylinder because, like offset printing and flexography, it uses a rotary printing press. Once a staple of newspaper photo features, the rotogravure process is still used for commercial printing of magazines, postcards, and corrugated (cardboard) and other product packaging.
An anilox roll. In printing, anilox is a method used to provide a measured amount of ink to a flexographic (flexo) printing plate. [1] An anilox roll is a hard cylinder, usually constructed of a steel or aluminum core which is coated by an industrial ceramic, typically chromium(III) oxide powder, whose surface is engraved with millions of very fine dimples, known as anilox cells.
The printing cylinders are usually made from copper plated steel, which is subsequently chromed, and may be produced by diamond engraving; etching, or laser ablation. Gravure printing is known for its ability to produce high-quality, high-resolution images with accurate color reproduction and using viscosity control equipment during production.
