gravure printing examples

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 popularity of the Su… 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? (2011) and the use of an industrial gravure printer for OPV preparation by Yang et al. Alibaba offers 661 Gravure Printing Sample Suppliers, and Gravure Printing Sample Manufacturers, Distributors, Factories, Companies. The mechanical engraving of gravure cylinders started around the 1960s and is called a Klischograph system. 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 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. Find high quality Gravure Printing Sample Suppliers on Alibaba. These early prints were used by the goldsmiths to display the range of engravings available to the customer. Global Site: www.futec-global.com. 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. liquid ink) is approximately 80% solvent and 20% solid matter. Figure 7.5 - Typical gravure cell formation. Beside the printing savings, this could eliminate one pocket in the bindery, saving about $1/M-$1.20/M catalogs printed. Source- Bobst Rotomec. The type of shore hardness will vary with the type of substrate being printed. Other noteworthy examples are the printing of an OPV on paper reported by Hübler et al. 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. 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. An example of early rotogravure was the introduction of newspaper supplements 1930s –1960s which carried rotogravure printed photographs. 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. (2013). Whereas the mechanical cell is a pyramid shape, the laser is a scoop shape. 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. 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. Printing Technology using the lower parts of the printing block for ink transfer. That is a lot of non-solid material that needs to leave the system quickly. Figure 7.2 - Principles of gravure process. The positioning of the doctor blade assembly is important. The screen process has a similar characteristic. Gravure press configurations fall into three categories: sheet-fed presses, dedicated in-line presses and single units used in combination with other printing processes. This website uses cookies to improve your experience. The chemical composition of the gravure ink can also influence the effectiveness of the electro-static assist system. The drying unit is positioned above the print unit meaning that after the print sequence the web travels upwards into the dryer. 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. In gravure it can be produced as two 36-page froms with a four-page cover. Types of gravure printing block –plate – cylinder Gravure printing Prof. Dr. Ulrich Moosheimer Seite 14 substrate material ink printing cylinder impression cylinder doctor blade An ‘etched’ polymer plate can be produced with indentations of varying depth which ‘hold’ the ink. GRAVURE Printing - cylinder engraving 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. Historically it was used for the production of wet glue labels but has now largely died out. The configuration of the sheet-fed gravure press is very similar to the litho press with a feeder and sheet delivery system. 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 (See Figure 7.4). The image to be engraved is scanned and the data is digitized. This type of gravure unit is usually incorporated into a dedicated in-line litho or flexo press or a multi-process platform press. The image is transferred directly to the substrate from the recessed image which is etched onto the gravure cylinder (See Figure 7.3). Figure 7.3 - Principles of gravure process. 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 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. 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. Gravure (noun) intaglio printing Gravure (noun) a printing plate used in the process of gravure. Gravure Printing - Here, the printing elements are recessed. FUTEC’s 100% print inspection guarantee: How to automate your quality control on typical defects occurring in gravure, flexo and label printing. A doctor blade assembly holds the doctor blade, which is in constant contact with the rotating print cylinder. Maintaining the correct ink viscosity is critical and the viscosity readings can be made manually or automatically. 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. Just be sure: You can control 100% of your product at any stage of the process chain. 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. The transfer of the ink from the cell to the substrate is a capillary action. basically a plate is covered with grease where no ink is desired (ink does not adhere to the grease). Using our tried and trusted flaw detection systems, you can automate your quality control checks and gain 100% transparency of your printing process. 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. A rougher and less smooth substrate can have an adverse effect on the ink transfer resulting in missing dots and poor print. (See Figure 7.5). Our core market for many years. applications in gravure printing. 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. We find most of the defects which make labels aesthetically unacceptable. Photopolymer plate systems for gravure have been developed as well as computer-to-cylinder systems. The image areas consist of honey comb shaped cells or wells that are etched or engraved into a copper cylinder. The thickness of the doctor blade can also be varied to assist in achieving the best doctoring result. 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. Gravure has traditionally been used as a long run process for wet-glue labels. 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 evaluation process allows all prevention, elimination and documentation of potential printing defects. 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. Tremendous progress has been made towards the use of gravure printing in highly-scaled electronics. Stop Scuffing in Its Tracks. Printed electronics is a set of printing methods used to create electrical devices on various substrates. wrong copy, mis-register, spots, debris or missing print. Electro assist generates an electric field in the ‘nip’ area. Reticulation can be created by inks that are either too thin in viscosity or the solvent balance is incorrect. Figure 7.7 - Location of docter blade on gravure unit. 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. Security printing eg stamps, banknotes, bonds. 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. The ‘doctoring’ action removes the surplus ink from the non-image areas leaving fresh ink in the cell cavities. The ink has either a chemical solvent or it is water-based. 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. They are both designed to be very fast drying. Gravure printing is an example of intaglio printing. Gravure and rotogravure. 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 unetched areas of the cylinder represent the non-image or unprinted areas. The digital information controls the engraving section of the machine. The image area on the cylinder is produced by engraving a cell formation that differs in depth and size. 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). Figure 7.1 - Modern gravure printing press. The depth of penetration of the stylus is controlled by the digital information and follows the tones and densities of the original artwork. Our technology serve as an opportunity to show who you are as a company. Another method of identifying the gravure process is the reticulation that can occur within the solid area of the print.
