Exploring Industrial Printing Techniques

1. Printing Types The main industrial printing processes are: Offset lithography. Flexography. Digital printing: inkjet & xerography. Gravure. Screen printing.

2. Relief Printing In relief printing the image to be transferred to paper (or other surface) is raised above the surface of the printing plate. Ink is applied to the raised surface then rolled or stamped onto the substrate. The relief printing process is similar to using an ink pad and stamp such as in rubberstamping. Flexography and letterpress are forms of relief printing.

5. Flexography Frequently used for printing on plastic, foil, acetate film, brown paper, and other materials used in packaging, flexography or flexographic printing uses flexible printing plates made of rubber or plastic. The inked plates with a slightly raised image are rotated on a cylinder which transfers the image to the substrate. Flexography uses fast-drying inks, is a high-speed print process, can print on many types of absorbent and non-absorbent materials, and can print continuous patterns (such as for gift wrap and wallpaper). Some typical applications for flexography are paper and plastic bags, milk cartons, disposable cups, and candy bar wrappers. Flexography printing may also be used for envelopes, labels, and newspapers.Watch https://youtu.be/vuGptR330VU

9. Intaglio Intaglio (/ɪnˈtæli.oʊ/ in-TAL-ee-oh; Italian: [inˈtaʎʎo]) is the family of printing and printmaking techniques in which the image is incised into a surface, and the incised line or sunken area holds the ink. It is the direct opposite of a relief print.

11. Gravure Gravure is a printing method in which an image is applied to a printing substrate by use of a metal plate mounted on a cylinder. Unlike other processes, gravure uses a depressed or sunken surface for the desired image. The image to be reproduced is etched into the metal plate, sometimes with the use of a laser . The metal plate is bathed in ink during the process and then wiped clean before application to the substrate. While gravure printing can produce high-quality results rapidly, the costs are significantly higher than other printing methods, including flexography or various forms of digital printing .

14. Etching

15. In traditional pure etching, a metal (usually copper, zinc or steel) plate is covered with a waxy ground which is resistant to acid. The artist then scratches off the ground with a pointed etching needle where he or she wants a line to appear in the finished piece, so exposing the bare metal.

21. Digital printing Digital printing refers to methods of printing from a digital-based image directly to a variety of media. It usually refers to professional printing where small-run jobs from desktop publishing and other digital sources are printed using large-format and/or high-volume laser or inkjet printers.

22. Digital Printing • It is not Just Your color Ink jet Printer • Xerography, also known as electrophotography, is a printing and photocopying technique that works on the basis of electrostatic charges. The xerography process is the dominant method of reproducing images and printing computer data and is used in photocopiers, laser printers and fax machines. • A dye-sublimation printer is a computer printer which employs a printing process that uses heat to transfer dye onto materials such as a plastic, card, paper, or fabric.

25. Silkscreen/ Serigraphy Silkscreen process is a a printmaking technique in which a mesh cloth is stretched over a heavy wooden frame and the design, Photo emulsion painted on or affixed by stencil, is printed by having a squeegee force color through the pores of the material in areas not blocked out by a glue sizing.
