The document discusses different printing techniques, including screen printing, which is used for t-shirts and billboards. Digital printing uses inkjet or laser printing without plates. Engraving creates raised surfaces on paper using a metal die. Flexography uses flexible plates to print on packaging materials like bags and cups. Gravure and letterpress are older techniques, while offset lithography uses plates to transfer images to paper. Reprographics involves duplicating images electronically or mechanically. Thermography applies powder to adhere ink in stationery printing.

- 5. ENGRAVING Engraving creates araised surface on paper while inking. A metal die is created with an impression which is cut into the surface and filled with opaque engraving ink. When pressed against the paper, it creates raised areas which are coated with ink.
- 6. FLEXOGRAPHY Used for productpackaging, it uses plastic or rubber printing plates that are flexible, to print on foil, plastic, brown paper, acetate film and all types of packaging materials. Typical applications are milk cartons, candy wrappers, plastic bags, disposable cups and all types of paper such as envelopes, newspapers and labels.
- 7. GRAVURE Commonly used forpackaging and labels in extremely large catalog and magazine runs gravure is a process that is mostly used for fine art prints.
- 8. LETTERPRESS Letterpress is theoldest printing technique known, pioneered in the 15th Century by Johannes Gutenberg. Ink is applied to a raised portion of the plastic or metal printing plate, which is applied to the paper, leaving an inked impression.
- 9. OFFSET LITHOGRAPHY This processof printing uses printing plates on flat surfaces. Water and ink is applied to the image on a printing plate which is chemically treated so that only the colors, types and shape on the plate will accept ink.
- 10. REPROGRAPHICS A term forduplication or photocopying images that are a virtual likeness of the original. The process can be electronic, mechanical or photographic such as xerography, photocopying, scanning or digital printing.
- 11. THERMOGRAPHY Thermography is commonlyknown as “poor man’s engraving” and is used for stationery printing. A special powder is applied to a document which adheres to the ink on the paper.
