Uses of stationery[edit]
Printing[edit]
Best School Stationery Items & Supplies In Cuttack Printing is the process of applying a colouring agent to a surface to create a body of text or illustrations. This is often achieved through printing technology, but can be done by hand using more traditional methods. The earliest form of printing is wood blocking.
Letterpress[edit]
Example of inked letterpress process
Main article: Letterpress printing
Letterpress is a process of printing several identical copies that presses words and designs onto the page. The print may be inked or blind, but is typically done in a single color. Motifs or designs may be added as many letterpress machines use movable plates that must be hand-set. Letterpress printing remained the primary method of printing until the 19th century.
Single documents[edit]
Main article: Computer printer
When a single document needs to be produced, it may be handwritten or printed typically by a computer printer. Several copies of one original paper can be produced by some printers using multipart stationery. Typing with a typewriter is obsolete, having been largely superseded by preparing a document with a word processor and printing the document.
Thermographic[edit]

Main article: Thermographic printing
Thermographic printing is a process that involves several stages but can be implemented in a low-cost manufacturing process. The process involves printing the desired designs or text with an ink that remains wet, rather than drying on contact with the paper. The paper is then dusted with a powdered polymer that adheres to the ink. The paper is vacuumed or agitated, mechanically or by hand, to remove excess powder, and then heated to near combustion. The wet ink and polymer bond and dry, resulting in a raised print surface similar to the result of an engraving process.
Embossing[edit]
Example of an embossed design
Embossing is a printing technique used to create raised surfaces in the converted paper stock. The process relies upon mated dies that press the paper into a shape that can be observed on both the front and back surfaces. Two things are required during the process of embossing- a die and a stock. The result is a three-dimensional (3D) effect that emphasizes a particular area of the design.
Engraving[edit]
Example of a brass engraving plate, showing heavy wear. The plate is hand or machine engraved, inked, and forced into paper at extremely high pressures.
Main article: Engraving
Engraving is a process that requires a design to be cut into a plate made of relatively hard material. The metal plate is first polished so that the design cut can be easily visible to the person. This technology has a long history and requires a significant amount of skill, experience, and expertise. The finished plate is usually covered in ink, and then the ink is removed from all of the un-etched portions of the plate. The plate is then pressed into paper under substantial pressure. The result is a design that is slightly raised on the surface of the paper and covered in ink. Due to the cost of the process and expertise required, many consumers opt for thermographic printing, a process that results in a similarly raised print surface, but through different means at less cost.
