The angle of attack to the cylinder can be adjusted from a 90 degree angle to a much sharper 45 degree angle and this facility allows the printer to achieve the optimum position for a clean wipe and the best possible printed result. A rougher and less smooth substrate can have an adverse effect on the ink transfer resulting in missing dots and poor print. One of the problems with the gravure process is a printing defect called ‘dot skipping’ and results in halftone dots being missed on the printed image.This is a result of a poor transfer of ink from the image cells to the substrate. There are three methods of imaging the gravure cylinder; The gravure cylinder comprises of a steel base, then a layer of copper and finally a polished chrome surface which is applied after the imaging process. The self–adhesive label market tends to service the short to medium run markets and the gravure process has never been considered by the label printer as the most suitable. This type of gravure unit is usually incorporated into a dedicated in-line litho or flexo press or a multi-process platform press. (2013). The cell structure of the mechanically engraved cylinder is governed by the shape of the stylus head and is a four sided pyramidal shape, the same as the cell formation on the mechanically engraved anilox rollers used in flexo printing. Unlike letterpress and flexo printing which are relief processes, the gravure process prints directly onto the substrate. The thickness of the doctor blade can also be varied to assist in achieving the best doctoring result. 4.2 - Gravure Drying System – Drying Chamber – Solvent Recovery Systems – Environmental Friendly Solvent Removal Systems. Source- Bobst Rotomec. Beside the printing savings, this could eliminate one pocket in the bindery, saving about $1/M-$1.20/M catalogs printed. After the engraving process is completed it is necessary to chrome the cylinder surface. Every single relevant flaw is mapped and documented. However, this is not the case with laser imaged cylinders as the laser can engrave half a cell, producing a straight edge.This control over the engraving process illustrates the level of print quality that can be produced by the gravure process. Gravure printing is a direct descendent of older intaglioprinting (gravure and intaglio, commonly used synonymously, are different processes; all gravure printing is intaglio, yet all intaglio printing is not gravure—for example, copperplate printing, which is an intaglio process without being considered a gravure process), developed around the same time as Gutenberg was developing relief-based printing … Gravure is an excellent process for applying metallic inks and finishes with a high level of lustre. Gravure and rotogravure. Electro assist generates an electric field in the ‘nip’ area. Adjustments can be made to the speed of the ink drying by the introduction of a faster or slower drying solvent, however this adjustment must be done under tight control as it is important that the correct balance of the solvents which make up the ink formula is maintained. … Gravure printingGravure printing Print methods to choose from – Flexo – UV flexo – UV Letterpress – UV Offset – Rotary (& flatbed) screen – Gravure Film weight / ink deposit depend on print method Litho 1,2-1,5 Letterpress 1,8-2,5 UV Flexo / Flexo 2-4 Screen 8 - 10 Gravure 6 - 10 However the modern doctor blade is now a replaceable item which removes the need for re-sharpening by hand. The impression roller applies the downward  force to the print cylinder. The ink transfer can also be influenced by the absorbency of the substrate being printed. GRAVURE Printing - cylinder engraving Gravure Printing Inks Industry, 2018 Market Research Report - The 'Global and Chinese Gravure Printing Inks Industry, 2013-2023 Market Research Report' is a professional and in-depth study on the current state of the global Gravure Printing Inks industry with a focus on the Chinese market. (See Figure 7.4). The screen process has a similar characteristic. More recently a direct digital laser etching process has been introduced, which will eventually reduce the cost of imaging gravure cylinders. (See Figure 7.4). E.g. • Gravure cum Kiss coating method for very low viscosity coatings Some Modifications of Gravure Printing orSome Modifications of Gravure Printing or coatingcoating • Gravure cum Kiss coating method for very low viscosity coatings 67. Using our tried and trusted flaw detection systems, you can automate your quality control checks and gain 100% transparency of your printing process. The ink from the top surface is wiped off and the ink in the recesses is transferred to the paper (example: engraving, gravure). Figure 7.8 - Gravure unit showing drying head. Direct laser engraved cylinders are imaged using a laser engraving unit that is controlled by a digital file. The chemical composition of the gravure ink can also influence the effectiveness of the electro-static assist system. Security printing eg stamps, banknotes, bonds. (See Figure 7.8). The gravure printing process is done with flat plates or, more commonly, with cylindrical surfaces. An original is scanned into a computer, the various image densities are determined, and lasers etch the cylinder. There are 523 OEM, 456 ODM, 78 Self Patent. Gravure printing is a particularly promising printing technique because it combines high print speed with high resolution patterning. GRAVURE PRINTING IN LABELS. The laser engraves directly onto the zinc surface of the cylinder and is considerably faster than mechanical engraving, producing a cell formation at 70,000 cells per second. Label press configurations and ancillary equipment, Die-cutting and Tooling: A guide to the manufacture and use of cutting, embossing and foiling dies, anvils and cylinders, The digitalization of labels and packaging production, Traditional method photographically using carbon tissue and acid etch called chemical etching, Excellent print quality - excellent sharpness and reproduction, Precise inking with no color variation throughout the print run, Consistent and substantial ink film weight, Wet on dry - excellent half-tone reproduction, Long cylinder life - making repeat runs very economical, Most suitable process for printing of metallic inks, Laser engraving high quality - 70,000 cells per second variable screen, High preparatory and origination costs, but due to improved technology these have reduced, Most gravure ink systems solvent based (environmental issues), Self-adhesive labels. Our core market for many years. Solvent based inks require infra-red and/or hot air drying to drive off the solvent content. The doctor blade is positioned close to the point where the two cylinders are in contact with the substrate which is sandwiched between these cylinders. Labels & Labeling has been the global voice of the label and package printing industry since 1978. An ‘etched’ polymer plate can be produced with indentations of varying depth which ‘hold’ the ink. Gravure inks can be formulated using different types of solvent systems and the printer must ensure that any solvent used is of the correct system. The use of chemical etching for gravure printing within the label industry is very limited and this article will focus on the two main engraving systems used today i.e. Laser engraving removes the problem of image inconsistency when a duplicate cylinder is required. The cylinder, which includes the picture, gets engraved, implying that minor openings are created into the cylinder, which symbolizes the point image. An example of early rotogravure was the introduction of newspaper supplements 1930s –1960s which carried rotogravure printed photographs. The steel doctor blade is supported by a backing blade to give better stability. The facility to produce varying cell size and also cell shapes means that the cells can be tailored to produce very high resolution tonal values, particularly for vignettes with no ‘saw edge’ effect on small text and a much improved ink transfer. These early prints were used by the goldsmiths to display the range of engravings available to the customer. Rotogravure can also be defined as a remedy printing press that utilizes an engraved, repeatedly metal, print container to transmit a design by spinning through ink and onto printing textures. Electro-static assist systems do offer the gravure printer some excellent benefits including improvements in print quality on less expensive stock, faster press speeds and less substrate waste. The ink is transferred to a substrate (paper, plastic, film, and more) using a rotary press.Rotogravure, or gravure, is an old process. Because the gravure ink is a solvented system the sheet-fed press will have an extended sheet delivery system into which a hot air drying system is located, this will also include an extraction system to ensure that the solvent vapor is removed. Printed electronics is a set of printing methods used to create electrical devices on various substrates. Printing Technology using the lower parts of the printing block for ink transfer. The substrates on the rotogravure press go through on average 4~6 meters of distance between color stations; on a flexographic press, goes through 4-6cm. A thinner blade removes slightly more ink from the cell and albeit this is a very small amount it can slightly reduce the density of the color being printed. In this thesis, gravure printing for printed electronics is advanced on multiple levels. The ink on the non-image area is ‘doctored’ clean (wiped) by the doctor blade which is positioned over the cylinder (See Figure 7.7) at a point just prior to the nip area. Those out of tolerance can be marked with the option to be cut and removed later. Sheet-fed gravure is rarely used in self-adhesive label printing. This is called the ‘nip' area and is the point at which the ink from the recessed cells is transferred to the substrate. E-Mail: sales@futeceurope.com The gravure cylinder revolves in a liquid ink with the ink being applied to the whole of the imaged print cylinder i.e. Gravure press configurations fall into three categories: sheet-fed presses, dedicated in-line presses and single units used in combination with other printing processes. Gravure printing is still widely used for the commercial production of post cards, magazines, newspapers, and corrugated cardboard (and other packaging materials). For most purposes, the minimum size is 4 point to 10 point type, but that is a wide range. Stop Scuffing in Its Tracks. Rolls with sub-5 μm resolution can be fabricated utilizing silicon microfabrication. The mechanical engraving of gravure cylinders started around the 1960s and is called a Klischograph system. We find most of the defects which make labels aesthetically unacceptable. Reticulation can be created by inks that are either too thin in viscosity or the solvent balance is incorrect. Gravure has traditionally been used as a long run process for wet-glue labels. applications in gravure printing. The gravure process is advanced in terms of tooling and understanding of printing physics as well as its application to Gravure (noun) a printing plate used in the process of gravure. Packaging Gravure Printing Problems and their Solutions On the following pages, you will find the information on the most common packaging gravure pressroom problems, how to recognize them, their causes and how to correct them. The gravure doctor blade unit is far more sophisticated than the type used in the flexo system. Gravure printing, photomechanical intaglio process in which the image to be printed consists of depressions or recesses on the surface of the printing plate. The surface of the impression roller is rubber covered and the ‘shore hardness’ of the rubber can be varied to increase or decrease the dwell time ensuring that there is maximum dwell at the point of contact between the substrate, impression cylinder and the image cylinder. The invention of photography led to the method of transferring a photo image onto a carbon tissue coated in a light-sensitive gelatine which allowed the etching of an image onto a steel, copper covered cylinder. It is important that the ink is fully transferred from the cell and there is no residual dried ink left in the base of the cell. The positioning of the doctor blade assembly is important. This way, you are always sure about the quality and able to deliver 100% transparency. Every time the stylus penetrates the copper it removes a chip from the surface creating a cell shaped indentation. Figure 7.2 - Principles of gravure process. The web or sheet travels through these two cylinders and considerable pressure is applied between the two cylinders causing the ink in the recessed image cells to be transferred onto the substrate. The unetched areas of the cylinder represent the non-image or unprinted areas. basically a plate is covered with grease where no ink is desired (ink does not adhere to the grease). Highly reflective copper is a poor material choice so alternative special alloys, plastics and ceramics are used. Gravure Printing 4.1 - Structure of Gravure Cylinder: Gravure cylinder parts – Axis, Shaft, Diameter, Circumference and Face length. Gravure printing is a very promising technique for printed electronics that combines high resolution with high printing speed. The deeper the stylus penetrates, the larger the cell, the lighter the penetration the smaller the cell. The ink has either a chemical solvent or it is water-based. Intaglio gravure printing originated with the goldsmith engravers in about 1446. Gravure units are typically added as part of a combination press configuration. Printing typically uses common printing equipment suitable for defining patterns on material, such as screen printing, flexography, gravure, offset lithography, and inkjet.By electronic industry standards, these are low cost processes. Other noteworthy examples are the printing of an OPV on paper reported by Hübler et al. Types of gravure printing block –plate – cylinder Gravure printing Prof. Dr. Ulrich Moosheimer Seite 14 substrate material ink printing cylinder impression cylinder doctor blade The doctor blade is positioned close to the point where the two cylinders are in contact with the substrate which is sandwiched between these cylinders. The intaglio process was further developed in the early 17th century when intaglio printing, also known as gravure printing, began to use metal plates which carried the etched image which was then printed onto the substrate. Figure 7.7 - Location of docter blade on gravure unit. Engravers mastered the art of varying the depth of the engraving or etching which allowed differing shades of color to be achieved-exactly the same principle as today's gravure process. Because the inks are liquid and very fast drying it is necessary for the ink to be constantly circulated through the ink weir, ink trough and the ink pumping system. The drying unit is positioned above the print unit meaning that after the print sequence the web travels upwards into the dryer. The gravure process can be easily identified by the saw tooth or serrated edge visible on the printed text and on the edges of solid color areas. Every gravure printing unit comprises of two cylinders, a printing cylinder which carries the image, and a rubber covered impression cylinder. For example, you can produce a 76-page catalog on offset as three 24-page forms and a four-page cover. They are both designed to be very fast drying. An example of early rotogravure was the introduction of newspaper supplements 1930s –1960s which carried rotogravure printed photographs. However the gravure press will usually have only one printing unit and not multiple print heads and therefore will print only one color at a time. The cell shape of the laser engraved cylinder differs from the mechanical system. Gravure (noun) an intaglio print produced by gravure. This is brought to you as another fulfillment of … The units, which are in a fixed position, are located in the press to give the best position to achieve the optimum printed result for highly reflective metallic inks and special coatings. The goldsmiths not only engraved their products but also developed an etching method useing nitric acid. One of the major differences between the in-line gravure press and the in-line litho and flexo presses is the position of the drying system. Gravure (noun) intaglio printing Figure 7.3 - Principles of gravure process. This saw edge is a characteristic of the process and is created by the outer edge section of the individual cells which make up the image. The type of shore hardness will vary with the type of substrate being printed. This method of engraving requires the image cylinder to be revolving while a diamond tipped stylus, which is oscillating at 4000 times a second, pierces the surface of the image cylinder. Gravure label presses are now used for both wet glue and self-adhesive label manufacture, particularly for the long run paper and filmic label market. It uses a depressed or sunken surface for the image. Featuring the latest technological advances, industry news, case studies and opinions, it is the leading resource for printers, brand owners, designers and suppliers. Tremendous progress has been made towards the use of gravure printing in highly-scaled electronics. The main examples of this printing technology are letterpress which, until a few decades ago, was the dominant printing technology and flexography which, by the middle of this century, had started to be used more and more in packaging printing. The ‘doctoring’ action removes the surplus ink from the non-image areas leaving fresh ink in the cell cavities. As result, the horizontal registration is often much less accurate on the rotogravure press, as the width of the substrate gets wider the accuracy declines. A doctor blade assembly holds the doctor blade, which is in constant contact with the rotating print cylinder. Founded in 1977 in Japan, FUTEC is a pioneer of 100% automatic flaw detection systems for print and surface inspection for commercial, packaging and label markets. Global Site: www.futec-global.com. The images were hand engraved onto copper, gold and silver and the recessed image was filled with a black ink or enamel known as Niello and then pressed onto paper. (See Figure 7.5). Building on earlier printing methods, modern gravure began in the late 19th century, and became widespread in the early 20th century. Figure 7.1 - Modern gravure printing press. wrong copy, mis-register, spots, debris or missing print. Gravure imaged cylinders or sleeves are manufactured with a copper outer surface on a steel base, If the cylinder is to be imaged with a mechanical engraving system then the copper layer is sufficient, however if the cylinder is to be direct laser engraved then an additional zinc layer is required. Scuffs or scratches in the ink are likely caused by the ink itself, the press … (See Figure 7.2). At this stage, irregularities in the process that cause recurrent defects can be determined and an instant warning is given to prevent further defects. The depth and width of the cell determines the volume of ink delivered (see Figure 7.6). Digital PrintingIn an inkjet printer the image that needs to be printed is created by small droplets of … filmic – paper – metallic. Photopolymer plate systems for gravure have been developed as well as computer-to-cylinder systems. Traditionally the doctor blade would be removed and re-sharpened by the printer using an oiled stone, and this would be done at intervals throughout the print run. Find high quality Gravure Printing Sample Suppliers on Alibaba. The drying heads on the gravure press are positioned ‘above’ each print head which means that the web will travel upwards after leaving each printing head. As previously explained the image cylinder rotates in the ink duct coating the whole surface of the image cylinder with liquid ink including the image cells. Gravure is small cells recessed into a cylinder that hold ink. Just be sure: You can control 100% of your product at any stage of the process chain. In Figure 7.2 you can see the configuration of the gravure unit of the type used in a multi-process combination press with the web, after printing, traveling upwards  into the drying head and then passing downwards over a chilled roller and then into the next print unit for printing the next color. This process of chroming gives the image cylinder a much harder surface, extending the life of the cylinder image and improving the doctoring process by ensuring that all the surplus ink is removed from the surface of the non-image area. Depending on the quality, the resulting print may look similar to, or the same as those produced with the traditional photogravure process using etched cylinders. The drying system on the gravure label press differs from the systems used on litho, flexo and screen presses. The image to be engraved is scanned and the data is digitized. The image area on the cylinder is produced by engraving a cell formation that differs in depth and size. Gravure (noun) a printing process that uses an etched or engraved plate; the plate is smeared with ink and wiped clean, then the ink left in the recesses makes the print. In gravure it can be produced as two 36-page froms with a four-page cover. Figure 7.5 - Typical gravure cell formation. Whereas the mechanical cell is a pyramid shape, the laser is a scoop shape. By varying the thickness of the doctor blade  the printer can also control the volume of ink left in the cell. The main examples of gravure printing are Rotogravure printing and, in the area of arts and crafts, copper plate engraving and die‐stamping (also security printing). 4.3 - Doctor Blade –Structure, Types and Mechanisms of doctor blade. Rotogravure – gravure for short – is a type of intaglio printing process which utilizes an engraved cylinder fixed to a rotary printing press. liquid ink) is approximately 80% solvent and 20% solid matter. there are no inking rollers, ink duct or anilox rollers used in the gravure unit. The cylinder is washed with ink; a doctor blade removes the excess, leaving ink only in the cells. Alibaba offers 661 Gravure Printing Sample Suppliers, and Gravure Printing Sample Manufacturers, Distributors, Factories, Companies. Maintaining the correct ink viscosity is critical and the viscosity readings can be made manually or automatically. That is a lot of non-solid material that needs to leave the system quickly. mechanical and laser. The majority of inks used in the gravure process are solvent based, however there are some gravure printed self-adhesive labels that are printed using UV gravure inks. This impression roller is also in contact with an additional roller called the ‘support roller’ which gives additional support to the impression roller.
