Pre-press
Prepress is the term used in the Printing and Publishing industries for the processes and procedures that occur between the creation of a print layout and the final printing. The prepress process includes the preparation of artwork for press, media selection, proofing, quality control checks and the production of printing plates if required. The artwork is usually delivery from the customer as a print-ready PDF file after being created in programs such as Adobe Indesign, Quark Express, Affinity Publisher or Scribus. Processes # Paper Selection is a very important step in prepress. Coated, Uncoated, Gloss, Matte, Silk, Satin, Recycled, Card, Bond or Specialist Papers are normal options available in different thicknesses such as 80gsm, 100gsm or 130gsm. # Binding Selection gives the customer multiple options for the spine of the publication such as Saddle-stitched,Perfect binding vs saddle stitching, paperspecs.com (last checked 2022-12-18) Perfect Bound or Case Bound, als ...

Transparency (graphic)
Transparency in computer graphics is possible in a number of file formats. The term " transparency" is used in various ways by different people, but at its simplest there is "full transparency" i.e. something that is completely invisible. Only part of a graphic should be fully transparent, or there would be nothing to see. More complex is "partial transparency" or "translucency" where the effect is achieved that a graphic is partially transparent in the same way as colored glass. Since ultimately a printed page or computer or television screen can only be one color at a point, partial transparency is always simulated at some level by mixing colors. There are many different ways to mix colors, so in some cases transparency is ambiguous. In addition, transparency is often an "extra" for a graphics format, and some graphics programs will ignore the transparency. Raster file formats that support transparency include GIF, PNG, BMP, TIFF, TGA and JPEG 2000, through either a '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Printing
Printing is a process for mass reproducing text and images using a master form or template. The earliest non-paper products involving printing include cylinder seals and objects such as the Cyrus Cylinder and the Cylinders of Nabonidus. The earliest known form of printing as applied to paper was woodblock printing, which appeared in China before 220 AD for cloth printing. However, it would not be applied to paper until the seventh century.Shelagh Vainker in Anne Farrer (ed), "Caves of the Thousand Buddhas", 1990, British Museum publications, Later developments in printing technology include the movable type invented by Bi Sheng around 1040 AD and the printing press invented by Johannes Gutenberg in the 15th century. The technology of printing played a key role in the development of the Renaissance and the Scientific Revolution and laid the material basis for the modern knowledge-based economy and the spread of learning to the masses.

Comb Binding
Comb binding (sometimes referred to as "cerlox" or "surelox" binding) is one of many ways to bind pages together into a book. This method uses round plastic spines with 19 rings (for US Letter size) or 21 rings (for A4 size) and a hole puncher that makes rectangular holes. Comb binding is sometimes referred to as plastic comb binding or spiral comb binding. Binding process To bind a document, the user first punches holes in the paper with a specialized hole punch. Pages must be punched a few at a time with most of these machines. If hard covers are desired, they must be punched as well. In bulk applications, a paper drilling machine may be used. Then the user chooses a spine size that will match the document. Standard sizes are (for 16 sheets of 20# paper) up to (for 425 sheets). Spine lengths are generally to match the length of letter-size paper. The rings on the spine open and insert into the holes in the page, then rest against the body of the spine, resulting in a closure ...

By December of that year, Adobe Systems released a mobile application of the product for iOS. In 2016 Adobe Sign was introduced as a way to request, receive, and submit e-signatures. The product offers integrations with Dropbox, Salesforce, Workda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prepress Proofing
A contract proof usually serves as an agreement between customer and printer and as a color reference guide for adjusting the press before the final press run. Most contract proofs are a prepress proof. The primary goal of proofing is to serve as a tool for customer verification that the entire job is accurate. Prepress proofing (also known as off-press proofing) is a cost-effective way of providing a visual copy without the expense of creating a press proof. If errors are found during the printing process on press, correcting them can prove very costly to one or both parties involved. Press time is the most expensive part of print media. The main objective of proofing is to produce either a soft or hard copy of what the final product will look like on press. Hard-copy proofing usually involves ink-jet printing or other technologies (i.e. Laminate Proof) to produce high-quality one-off copies of the production artwork. Soft proofing usually involves highly color accurate wide-gam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rasterisation
In computer graphics, rasterisation (British English) or rasterization (American English) is the task of taking an image described in a vector graphics format (shapes) and converting it into a raster image (a series of pixels, dots or lines, which, when displayed together, create the image which was represented via shapes). The rasterized image may then be displayed on a computer display, video display or printer, or stored in a bitmap file format. Rasterization may refer to the technique of drawing 3D models, or the conversion of 2D rendering primitives such as polygons, line segments into a rasterized format. Etymology The term "rasterisation" comes . 2D Images Line primitives Bresenham's line algorithm is an example of algorithm used to render a line. Circle primitives Algorithms such as Midpoint circle algorithm are used to render circle onto a pixelated canvas. 3D images Rasterization is one of the typical techniques of rendering 3D models.

Raster Image Processor
A raster image processor (RIP) is a component used in a printing system which produces a raster image also known as a bitmap. Such a bitmap is used by a later stage of the printing system to produce the printed output. The input may be a page description in a high-level page description language such as PostScript, PDF, or XPS. The input can also be or include bitmaps of higher or lower resolution than the output device, which the RIP resizes using an image scaling algorithm. Originally a RIP was a rack of electronic hardware which received the page description via some interface (e.g. RS-232) and generated a "hardware bitmap output" which was used to enable or disable each pixel on a real-time output device such as an optical film recorder, computer to film, or computer to plate. A RIP can be implemented as a software module on a general-purpose computer, or as a firmware program executed on a microprocessor inside a printer. For high-end typesetting, standalone hardware R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
File Transfer Protocol
The File Transfer Protocol (FTP) is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network. FTP is built on a client–server model architecture using separate control and data connections between the client and the server. FTP users may authenticate themselves with a clear-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it. For secure transmission that protects the username and password, and encrypts the content, FTP is often secured with SSL/TLS (FTPS) or replaced with SSH File Transfer Protocol (SFTP). The first FTP client applications were command-line programs developed before operating systems had graphical user interfaces, and are still shipped with most Windows, Unix, and Linux operating systems. Many dedicated FTP clients and automation utilities have since been developed for desktops, servers, mobile devices, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pre-flight (printing)
{{Unreferenced, date=October 2008 In printing, Preflight is the process of confirming that the digital files required for the printing process are all present, valid, correctly formatted, and of the desired type. The basic idea is to prepare the files to make them feasible for the correct process such as offset printing and eliminate costly errors and facilitate a smooth production. It is a standard prepress procedure in the printing industry (as it is imposition). The term originates from the preflight checklists used by pilots. The term was first used in a presentation at the Color Connections conference in 1990 by consultant Chuck Weger, and Professor Ron Bertolina was a pioneer for solutions to preflighting in the 1990s. Background In a common digital prepress workflow, a collection of computer files provided by clients will be translated from an application-specific format such as Adobe InDesign or QuarkXPress to a format that the raster image processor (RIP) can interpret.

Overprinting
Overprinting refers to the process of printing one colour on top of another in reprographics. This is closely linked to the reprographic technique of 'trapping'. Another use of overprinting is to create a rich black Rich may refer to: Common uses * Rich, an entity possessing wealth * Rich, an intense flavor, color, sound, texture, or feeling ** Rich (wine), a descriptor in wine tasting Places United States * Rich, Mississippi, an unincorporated comm ... (often regarded as a colour that is "blacker than black") by printing black over another dark colour. It is also the term used in the production of envelopes customised to order by printing images (such as logos) and texts (such as slogans) on mass-produced machine-made envelopes; the alternative way of producing such envelopes is to print "on the flat" and then cut out the individual shapes and fold them to form the envelopes. However the latter method is generally only economically viable for large print runs offer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trap (printing)
In printing, trap expresses the degree to which ink already printed on a substrate accepts another layer printed on top of it compared to how well the substrate (e.g., paper) accepts that ink. However, in the era of prepress software, the term came to refer to compensation for misregistration (when two layers of ink are not perfectly aligned) that was traditionally known as "chokes and spreads". Misregistration causes gaps or white-space on the final printed work. Correcting this involves creating overlaps (spreads) or underlaps (chokes) of objects during the print process. Registration Misregistration in the graphical workflow may be caused by human error, inaccuracies in the image setter, the film-to-plate or film-to-film copying steps or instability of the image carrier (e.g., stretch in film or plate), the press or the final media. These issues can be minimized, but not eliminated, given that any mechanical process produces some degree of error. However, the resulting gaps ...

Spot Color
In offset printing, a spot color or solid color is any color generated by an ink (pure or mixed) that is printed using a ''single run'', whereas a process color is produced by printing a series of dots of different colors. The widespread offset-printing process is composed of the four spot colors cyan, magenta, yellow, and key (black) commonly referred to as CMYK. More advanced processes involve the use of six spot colors ( hexachromatic process), which add orange and green to the process (termed CMYKOG). The two additional spot colors are added to compensate for the ineffective reproduction of faint tints using CMYK colors only. However, offset technicians around the world use the term ''spot color'' to mean any color generated by a non-standard offset ink; such as metallic, fluorescent, or custom hand-mixed inks. When making a multi-color print with a spot color process, every spot color needs its own lithographic film. All the areas of the same spot color are printed using ...
