Graphic technology — Process control for the production of half-tone colour separations, proofs and production prints — Part 6: Flexographic printing The flexographic printing plate, or cliché, which is mounted on the printing cylinder, is either made of rubber or more commonly of a photopolymeric material. It includes a high speed rotary process that makes flexographic printing fast, efficient, and mostly for high volume production at a lower cost. In Section 3, the focus is the demand side, concentrating on the desired characteristics of the various printing processes and their primary consumers by use and Unhardened composition is softened and absorbed by an absorbent sheet. Input/Output process diagrams are provided. printing technology, that is, the ink is first transferred to an intermediate carrier (rubber blanket) and from there onto the substrate. Flexo is versatile and consistent, providing quality print and reliable repeatability. Flexographic printing (also known as Flexo), results in a clearly printed image,with sharp colour quality. ... My question is how can we modify or replace flexographic printing press as we are not getting good results with our flexographic printing press. The pre-press process is extremely important for flexographic printing. Printing on these substrates with water was readily successful because of the absorbent nature of the paper fibers. Flexographic printing is a printing method that allows the printer to print on flexible substrates because the process uses flexible—rather than traditional rigid—raised-imaged printing plates. This type of printing is mostly used for non-porous materials like food service paper, plastic, foil, brown paper, and packaging materials. Flexographic printing is unique because it adapts well to different In our operator and engineer trainings I will explain this printing technique. These plates are attached to cylinders, and then inked by a roll that carries low-viscosity inks onto the plate which then transfers it onto the substrate. print ? Flexographic printing [82], [88], [89]: a ink is deposited on a cylindrical flexible relief printing plate to be transferred onto the solar cell (see Figure 2. Waterbased inks have been used for flexographic printing of paper and paperboard since the invention of the process. Flexographic printing is similar to Offset Lithography and Rotogravure printing in the fact that it is a rotary printing method. Flexographic printing can be used to print on materials including paper, plastics, film, synthetic papers, tag stock and more. PRINTING PROCESSES A printing process describes the method adopted by a system to transfer the image on to a substrate (material). Flexible Packaging Printing Processes Overview Slide 25 2009 Consumer Packaging Solutions For Barrier Performance Course ROTOGRAVURE Printing Rotogravure: (typically referred to as Gravure) An intaglio process (in-tal-yo means engraved or cut in) in which a negative image is etched into the surface of a copper printing This involves a specialty process whereby a graphic art file is converted into vector images and then each color within the file is separated onto a separate layer. It relies on rotating cylinders to apply the ink and feed the paper through the printing process. see Figure 1. Presses can print on a variety of films, foils, papers, corrugated board, and paperboard and achieve speeds of 500 to 2000 feet per minute. Flexography is a roll-feed web printing process.

This section describes the working process of printing and specifically that of flexographic printing. Flexographic printing has grown to the most used print technology in the label printing industry today, providing an optimal combination in quality, productivity, and flexibility. Negative-acting photohardenable compositions are useful in flexographic printing plate manufacture without the use of solvent development. SC6-0204 12/9/02 5:31 PM Page 8 Flexographic printing Flexography is a process in which the printing image stands up in relief. IKEA catalogue 2008 Advantage Largest cost blocks Seite 46 Printing technology using the higher parts of the printing block for ink transfer. Yet riding that thin line of consistency is easier said than done, as any number of issues can crop up in your process. ), but it has evolved a great deal over the years and is still one of the most reliable ways to produce great looking labels. plate. 4/17/2018 9 Flexography is the fastest growing conventional printing process, especially in packaging such as corrugated containers and flexible films. FLEXOGRAPHIC INKSFLEXOGRAPHIC INKS DIRTY PRINTING/DOT BRIDGING– Appearance of a dirty, grainy effect as a result of two or more process dots linking together. Improvements to this process are relatively recent and is due to print plates being made to greater precision, through the introduction of computer control and 3D systems. Flexographic Printing Prior to running a flexographic label job, the printer must make (or outsource) the printing plates. Before you can control the process, you have to understand it. The flexible printing form is favourable for printing on rough surfaces, but the high surface tension of the ink may cause printability problems. Flexography: Principles & Practices can help. This also means that a printing system will have a medium that carries the image in the first place before it enables the process of reproduction. Flexography is related to the oldest printing process, letterpress, because both flexography and letterpress print from a raised image. To get the best out of flexographic printing, you need to understand the process … Originally introduced in 1962 and updated significantly throughout its history, Flexography: Principles & Practices 6.0 is a complete re-write of … This is a high speed process, meaning that inaccuracies in preparing the artwork or platemaking can … of the printing industry, including a detailed discussion of the gravure and flexographic printing processes, inputs to each process, the associated products, and costs of production. Flexographic printing has gained steadily in popularity over the past half-century due to its wide range of applications and flexibility with many different substrates. Flexographic printing isn’t exactly a “new” technology (we’ve been using flexographic printing presses since we first got into the label industry over 30 years ago! This makes the flexo printing process popular with the packaging industry and many others. Absorbed composition can be removed from the sheet and recycled. This type of printing is mostly used for non-porous materials like food service paper, plastic, foil, brown paper, and packaging materials. The main difference with both processes is that offset printing is only done on flat surface while Flexographic printing can be used on almost any substrate with a flexible surface. This type of printing can be seen almost everywhere from the supermarket shelves, to shopping bags, tickets, tags and many other applications.
