gravure printing examples

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). The impression roller applies the downward  force to the print cylinder. Sheet-fed gravure is rarely used in self-adhesive label printing. Gravure printing is a direct descendent of older intaglio printing (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) Developments exist where vacuum metallised particle inks are reverse printed by the gravure process onto a clear substrate, such as a PP. Rolls with sub-5 μm resolution can be fabricated utilizing silicon microfabrication. wrong copy, mis-register, spots, debris or missing print. 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. These early prints were used by the goldsmiths to display the range of engravings available to the customer. 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. Gravure (noun) intaglio printing Tremendous progress has been made towards the use of gravure printing in highly-scaled electronics. 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. For example, the minimum font sizes used for both positive and reversed serif or sans serif type is based on the type of web press and whether you are printing to corrugated coated paper, uncoated newsprint, a polyester film or other substrates. 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. 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. 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. 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. 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. Direct laser engraving for gravure cylinder imaging is now widely used in the commercial, packaging and label markets. More recently a direct digital laser etching process has been introduced, which will eventually reduce the cost of imaging gravure cylinders. We'll assume you're ok with this, but you can opt-out if you wish. A rougher and less smooth substrate can have an adverse effect on the ink transfer resulting in missing dots and poor print. The cylinder, which includes the picture, gets engraved, implying that minor openings are created into the cylinder, which symbolizes the point image. 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. 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. liquid ink) is approximately 80% solvent and 20% solid matter. One of the biggest opportunities is in supporting and better equipping European flexographic print houses. The popularity of the Su… GRAVURE Printing - cylinder engraving 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. 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. Prior to this newspapers had published very few photographs. 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 transfer of the ink from the cell to the substrate is a capillary action. The type of shore hardness will vary with the type of substrate being printed. The gravure cylinder revolves in a liquid ink with the ink being applied to the whole of the imaged print cylinder i.e. Historically it was used for the production of wet glue labels but has now largely died out. The steel doctor blade is supported by a backing blade to give better stability. (See Figure 7.4). 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. This method gives a very bright and highly reflective appearance  resembling that of foil blocking. In this thesis, gravure printing for printed electronics is advanced on multiple levels. Global Site: www.futec-global.com. filmic – paper – metallic. 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. The gravure printing process is done with flat plates or, more commonly, with cylindrical surfaces. 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. This variation in the cell structure controls the amount of ink and therefore the strength of color being printed, because the ‘cell size’ or ‘dot size’ can be engraved to a very small specification, subtle variations in dot/tonal detail and color strength can be easily produced. Prior to this newspapers had published very few photographs. 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 … The web path of the litho and flexo press travels downwards after leaving each printing head. Maintaining the correct ink viscosity is critical and the viscosity readings can be made manually or automatically. The drying system on the gravure label press differs from the systems used on litho, flexo and screen presses. Find high quality Gravure Printing Sample Suppliers on Alibaba. Whereas the mechanical cell is a pyramid shape, the laser is a scoop shape. Rotogravure – gravure for short – is a type of intaglio printing process which utilizes an engraved cylinder fixed to a rotary printing press. 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. Using our tried and trusted flaw detection systems, you can automate your quality control checks and gain 100% transparency of your printing process. 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. This is brought to you as another fulfillment of … Just be sure: You can control 100% of your product at any stage of the process chain. Gravure Printing 4.1 - Structure of Gravure Cylinder: Gravure cylinder parts – Axis, Shaft, Diameter, Circumference and Face length. All the gravure press configurations used for self-adhesive label manufacture are in-line This means that there is a one printing unit per color and there are no real limitations on the number of printing heads used on an in-line press, (See Figure 7.1). 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. This was the beginning of the modern rotogravure process. Gravure printing is a very promising technique for printed electronics that combines high resolution with high printing speed. This takes the web through the infra-red or UV drying units which are positioned ‘below’ the print unit. E.g. Gravure has traditionally been used as a long run process for wet-glue labels. The drying unit is positioned above the print unit meaning that after the print sequence the web travels upwards into the dryer. Other noteworthy examples are the printing of an OPV on paper reported by Hübler et al. Intaglio gravure printing originated with the goldsmith engravers in about 1446. 4.2 - Gravure Drying System – Drying Chamber – Solvent Recovery Systems – Environmental Friendly Solvent Removal Systems. The unetched areas of the cylinder represent the non-image or unprinted areas. Featuring the latest technological advances, industry news, case studies and opinions, it is the leading resource for printers, brand owners, designers and suppliers. The depth and width of the cell determines the volume of ink delivered (see Figure 7.6). Those out of tolerance can be marked with the option to be cut and removed later. Definition of Rotogravure a process used for printing in which the paper is rolled through a cylinder that has numerous indentions Examples of Rotogravure in a sentence One of my grandmother’s most treasured possessions was a portrait of her parents that was printed in rotogravure … E-Mail: [email protected] Gravure (noun) a printing plate used in the process of gravure. 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. Security printing eg stamps, banknotes, bonds. mechanical and laser. The ‘doctoring’ action removes the surplus ink from the non-image areas leaving fresh ink in the cell cavities. Gravure and rotogravure. Labels & Labeling has been the global voice of the label and package printing industry since 1978. FUTEC’s 100% print inspection guarantee: How to automate your quality control on typical defects occurring in gravure, flexo and label printing. In gravure it can be produced as two 36-page froms with a four-page cover. The gravure doctor blade unit is far more sophisticated than the type used in the flexo system. Electro assist generates an electric field in the ‘nip’ area. Printing Technology using the lower parts of the printing block for ink transfer. 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. Every single relevant flaw is mapped and documented. The image is transferred directly to the substrate from the recessed image which is etched onto the gravure cylinder (See Figure 7.3). It uses a depressed or sunken surface for the image. Gravure units are typically added as part of a combination press configuration. 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. This type of gravure unit is usually incorporated into a dedicated in-line litho or flexo press or a multi-process platform press. Alibaba offers 661 Gravure Printing Sample Suppliers, and Gravure Printing Sample Manufacturers, Distributors, Factories, Companies. 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. 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. The ink from the top surface is wiped off and the ink in the recesses is transferred to the paper (example: engraving, gravure). By varying the thickness of the doctor blade  the printer can also control the volume of ink left in the cell. Figure 7.7 - Location of docter blade on gravure unit. Printed electronics is a set of printing methods used to create electrical devices on various substrates. Figure 7.1 - Modern gravure printing press. Every gravure printing unit comprises of two cylinders, a printing cylinder which carries the image, and a rubber covered impression cylinder. Source- Bobst Rotomec. 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. 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 configuration of the sheet-fed gravure press is very similar to the litho press with a feeder and sheet delivery system. 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. Unlike letterpress and flexo printing which are relief processes, the gravure process prints directly onto the substrate. The ink transfer can also be influenced by the absorbency of the substrate being printed. 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, photomechanical intaglio process in which the image to be printed consists of depressions or recesses on the surface of the printing plate. The gravure process is advanced in terms of tooling and understanding of printing physics as well as its application to 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. The thickness of the doctor blade can also be varied to assist in achieving the best doctoring result. Beside the printing savings, this could eliminate one pocket in the bindery, saving about $1/M-$1.20/M catalogs printed. Gravure and screen imaging cannot produce ‘half a screen’ and therefore cannot produce a straight edge. The file contains all the data required to reproduce the exact tonal values and detail that are required for the correct image reproduction. The cylinder is washed with ink; a doctor blade removes the excess, leaving ink only in the cells. … The depth of penetration of the stylus is controlled by the digital information and follows the tones and densities of the original artwork. 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. (2013). Gravure printing is a particularly promising printing technique because it combines high print speed with high resolution patterning. The digital information controls the engraving section of the machine. The cell shape of the laser engraved cylinder differs from the mechanical system. (See Figure 7.4). 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. 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. An original is scanned into a computer, the various image densities are determined, and lasers etch the cylinder. Stop Scuffing in Its Tracks. Gravure (noun) an intaglio print produced by gravure. GRAVURE PRINTING IN LABELS. However the modern doctor blade is now a replaceable item which removes the need for re-sharpening by hand. 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. Some gravure presses are equipped with an electrostatic assist system which operates by creating a positive and negative static charge between the ink and impression roller and the image cylinder which can assist in giving a smoother and more complete transfer of the ink from cell to substrate. An ‘etched’ polymer plate can be produced with indentations of varying depth which ‘hold’ the ink. 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. 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. 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. Planographic - Operates on the principle that water and oil don't mix. 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 ink is transferred to a substrate (paper, plastic, film, and more) using a rotary press.Rotogravure, or gravure, is an old process. (See Figure 7.8). Gravure Printing - Here, the printing elements are recessed. After the printing sequence the web then travels upwards into the dryer system, and it is important that the liquid ink is completely dry before the next printing sequence. 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. More recently it has made inroads into narrow and mid-web presses for self-adhesive labels where the ability of gravure to apply varnishes , lacquers and top coatings offers  particular advantages. 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 The chemical composition of the gravure ink can also influence the effectiveness of the electro-static assist system. The evaluation process allows all prevention, elimination and documentation of potential printing defects. 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 screen process has a similar characteristic. 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. The deeper the stylus penetrates, the larger the cell, the lighter the penetration the smaller the cell. The mechanical engraving of gravure cylinders started around the 1960s and is called a Klischograph system. Gravure printing has usually been the chosen process most suitable for printing fine tones with a sharp dot formation giving a high quality result and best suited to the long run markets. An example of early rotogravure was the introduction of newspaper supplements 1930s –1960s which carried rotogravure printed photographs. They are both designed to be very fast drying. Photopolymer plate systems for gravure have been developed as well as computer-to-cylinder systems. Figure 7.3 - Principles of gravure process. 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. • 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. Solvent based inks require infra-red and/or hot air drying to drive off the solvent content. There are 523 OEM, 456 ODM, 78 Self Patent. Our core market for many years. Direct laser engraved cylinders are imaged using a laser engraving unit that is controlled by a digital file. Scuffs or scratches in the ink are likely caused by the ink itself, the press … Gravure printing is an example of intaglio printing. Gravure printing can also be affected by the type of substrate being printed; a smooth surface allows a better contact between the image cells and the substrate surface giving a better ink transfer and less dot skipping. Gravure printing is still widely used for the commercial production of post cards, magazines, newspapers, and corrugated cardboard (and other packaging materials). Every time the stylus penetrates the copper it removes a chip from the surface creating a cell shaped indentation. This way, you are always sure about the quality and able to deliver 100% transparency. The gravure printing process is one of the three major processes that are used for catalogs, magazines, newspaper supplements, cartons, floor and wall coverings, textiles, and plastics. The positioning of the doctor blade assembly is important. That is a lot of non-solid material that needs to leave the system quickly. By comparing the master picture with the data of the printed product, the defects can be classified as either in or out of tolerance. applications in gravure printing. GRAVURE PRINTING TECHNOLOGY A TO Z and Quality Trouble Shooting Tips at Hotel Mulia Senayan - Jakarta Nov 19, 2013 ORIENT SOGYO CO., LTD. Hidenori Harada GRAVURE PRINTING TECHNOLOGY A TO Z What is happening in Japan Gravure printing industry? 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. Gravure is an excellent process for applying metallic inks and finishes with a high level of lustre. Figure 7.2 - Principles of gravure process. A doctor blade assembly holds the doctor blade, which is in constant contact with the rotating print cylinder. Reticulation can be created by inks that are either too thin in viscosity or the solvent balance is incorrect. The ink has either a chemical solvent or it is water-based. At this stage, irregularities in the process that cause recurrent defects can be determined and an instant warning is given to prevent further defects. (2011) and the use of an industrial gravure printer for OPV preparation by Yang et al. 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. This website uses cookies to improve your experience. Because gravure inks are a solvented system and dry very rapidly, it is necessary to keep the distance between the doctoring process and the print ‘nip’ to a minimum, ensuring that the ink remains as open and liquid as possible. The goldsmiths not only engraved their products but also developed an etching method useing nitric acid. Building on earlier printing methods, modern gravure began in the late 19th century, and became widespread in the early 20th century. 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. For most purposes, the minimum size is 4 point to 10 point type, but that is a wide range. This is called the ‘nip' area and is the point at which the ink from the recessed cells is transferred to the substrate. Figure 7.8 - Gravure unit showing drying head. 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. This impression roller is also in contact with an additional roller called the ‘support roller’ which gives additional support to the impression roller. Gravure Printing MachinesGravure Printing Machines 4/19/2018 69 68. (See Figure 7.2). Our technology serve as an opportunity to show who you are as a company. The ink used in Flexographic and Gravure printing (aka. The image area on the cylinder is produced by engraving a cell formation that differs in depth and size. In about 1640 a German engraver by the name of Von Seigen employed a new method called mezzotint and this was used to reproduce paintings in black and white and also in color. However the use of gravure in the label industry has been increasing, particularly as the facility to produce highly reflective metallic inks and specialised coatings by the gravure process means that gravure units are now used as individual units on combination label presses. The metallised particles are easily suspended in the solvent medium used in the gravure process and align smoothly and easily to the clear label substrate. Another method of identifying the gravure process is the reticulation that can occur within the solid area of the print. Produce ‘ half a screen ’ and therefore can not produce ‘ half screen...
