What is flexo packaging?
“Flexo printing” is an abbreviated term for “flexography” – a process that produces printing from a flexible relief plate. This process allows for printing on almost any material such as plastic, metallic films, cellophane, and paper.
What is the meaning of flexo printing?
flexography, form of rotary printing in which ink is applied to various surfaces by means of flexible rubber (or other elastomeric) printing plates. The inks used in flexography dry quickly by evaporation and are safe for use on wrappers that come directly in contact with foods.
What is flexo sleeve?
Flexographic printing sleeves are a technology that allows printing any type of material for both wide and narrow flexographic machines. Vibration filtration, thanks to damping mounting layer. Honeycomb structures enable high rigidity and extremely low density.
What is flexo material?
Originally, flexo plates were made from rubber, but are today made from photopolymer material in sheet form – which differentiates them from the fixed metallic printing plates of offset printing. The plates are flexible enough to be wrapped around cylindrical print/plate rollers.
How is flexography done?
How Does Flexography Work? In flexographic printing, the starting material comes in the form of a roll, which passes through a series of rotary flexible relief plates. A specialized roller feeds each flexible plate with ink, with a single flexible plate required for each individual printed color.
Why is flexographic ink so liquid?
The Reason Behind Water-Based Flexographic Ink Additive: If a specialized product such as silicones or waxes is to be produced, a formulator may need to include additional chemicals or substances to make the ink work. Amine: The chemical(s) used to transform a resin into a liquid state.
What are the advantages of flexography?
An advantage of flexography is that is a fast and economical method to print relatively simple designs on stand up packaging. It supports a range of colors. It can be used with water-based inks as well as oil-based inks. Currently water-based inks are popular because of their non-toxicity.
How is flexography used?
Flexography is a roll-feed web printing process. Flexographic printing is commonly used to print high volumes of labels and packaging. Presses can print on a variety of films, foils, papers, corrugated board, and paperboard and achieve speeds of 500 to 2000 feet per minute.
How is flexo ink made?
A flexographic preprint ink composition, which includes at least 3 weight percent of a pigment; at least 15 weight percent of a hydrolyzed gelatin; and water. The ink composition may also contain conventional additives, such as surfactants and defoaming agents, typically found in flexographic ink compositions.
What ink is used for flexography?
Flexographic printing is done on paper, cardboard, or plastic film. Liquid inks with a low viscosity are used for printing. There are water-based inks, solvent, and ultraviolet (UV)-cured inks among them.
Was ist der Unterschied zwischen Hochdruck und Flexodruck?
Flexodruck. Es ist ein Rollenrotationsdruckverfahren, bei dem flexible Druckplatten, die aus Fotopolymer oder Gummi bestehen, und niedrigviskose Druckfarben verwendet werden. Als Hochdruckverfahren sind die erhabenen Stellen der Druckform bildtragend, während der Druckwerksaufbau einfach ist und dem des Tiefdruckverfahrens ähnelt.
Was ist der Unterschied zwischen Offset und Flexodruck?
Beim Zeitungsflexodruck werden dünnflüssige, farbintensive, wasserbasierende Farben verwendet. Es entsteht ein abriebfesterer und geruchsärmerer Druck als beim Coldset. Der Zeitungsleser hat nach der Lektüre keine Druckerschwärze an den Fingern wie im Offset.
Welche Druckverfahren gibt es?
Der Zeitungsflexodruck stellt ein weiteres Einsatzgebiet dar. In den USA, Italien und Großbritannien werden Zeitungen im Flexodruck hergestellt. Das auf dem Weltmarkt dominante Zeitungsdruckverfahren ist jedoch der Rollenoffset . Das Tauchwalzendruckwerk (Die Rakel wäre bei dieser Laufrichtung ohne Funktion!)
Wie wird eine Druckform hergestellt?
Letztere werden durch Belichtung der druckenden und anschließendem Auswaschen der nicht druckenden Elemente hergestellt. Die Druckform, mit der neben Strich und Text auch Halbtöne durch Rasterung simuliert werden können, wird nach ihrer Herstellung auf den Druckzylinder gespannt.
