While errors should be corrected during the Color Proofing and proofreading stages, the main purpose of a press check is to make sure that the color on press comes as close as possible to the color proof. Color proofs are valuable guides, but due to the inherent differences between color proofing techniques and printing itself, proofs will match the printed sheet with varying degrees of exactness.

Areas that are commonly evaluated at a press check are: [1] [2] [3]

Post press check

While some printing jobs are delivered as printed, most printing is usually not complete until it is converted into a "finished" product. Post press includes various types of finish work such as trimming, embossing, foiling, die-cutting, scoring, folding and bindery. Post press checking can include:

A book is a medium for recording information in the form of writing or images, typically composed of many pages bound together and protected by a cover. It can also be a handwritten or printed work of fiction or nonfiction, usually on sheets of paper fastened or bound together within covers. The technical term for this physical arrangement is codex. In the history of hand-held physical supports for extended written compositions or records, the codex replaces its predecessor, the scroll. A single sheet in a codex is a leaf and each side of a leaf is a page.

In the field of computing, a printer is considered a peripheral device that serves the purpose of creating a permanent representation of text or graphics, usually on paper. While the majority of outputs produced by printers are readable by humans, there are instances where barcode printers have found a utility beyond this traditional use. Different types of printers are available for use, including inkjet printers, thermal printers, laser printers, and 3D printers.

Printmaking is the process of creating artworks by printing, normally on paper, but also on fabric, wood, metal, and other surfaces. "Traditional printmaking" normally covers only the process of creating prints using a hand processed technique, rather than a photographic reproduction of a visual artwork which would be printed using an electronic machine ; however, there is some cross-over between traditional and digital printmaking, including risograph.

<span class="mw-page-title-main">Printing</span> Process for reproducing text and images

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 evolved from ink rubbings made on paper or cloth from texts on stone tablets, used during the sixth century. Printing by pressing an inked image onto paper appeared later that century. 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.

<span class="mw-page-title-main">Flexography</span> Form of printing process

Flexography is a form of printing process which utilizes a flexible relief plate. It is essentially a modern version of letterpress, evolved with high speed rotary functionality, which can be used for printing on almost any type of substrate, including plastic, metallic films, cellophane, and paper. It is widely used for printing on the non-porous substrates required for various types of food packaging.

<span class="mw-page-title-main">Paper embossing</span> Process of creating either raised or recessed relief images and designs in paper and other materials

Embossing and debossing are the processes of creating either raised or recessed relief images and designs in paper and other materials. An embossed pattern is raised against the background, while a debossed pattern is sunken into the surface of the material but might protrude somewhat on the reverse side.

<span class="mw-page-title-main">Digital printing</span> Method of printing

Digital printing is a method 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.

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 often provided by the customer as a print-ready PDF file created in desktop publishing.

<span class="mw-page-title-main">Offset printing</span> Printing technique

Offset printing is a common printing technique in which the inked image is transferred from a plate to a rubber blanket and then to the printing surface. When used in combination with the lithographic process, which is based on the repulsion of oil and water, the offset technique employs a flat (planographic) image carrier. Ink rollers transfer ink to the image areas of the image carrier, while a water roller applies a water-based film to the non-image areas.

<span class="mw-page-title-main">Security printing</span> Field of the printing industry for banknotes and other security products

Security printing is the field of the printing industry that deals with the printing of items such as banknotes, cheques, passports, tamper-evident labels, security tapes, product authentication, stock certificates, postage stamps and identity cards. The main goal of security printing is to prevent forgery, tampering, or counterfeiting. More recently many of the techniques used to protect these high-value documents have become more available to commercial printers, whether they are using the more traditional offset and flexographic presses or the newer digital platforms. Businesses are protecting their lesser-value documents such as transcripts, coupons and prescription pads by incorporating some of the features listed below to ensure that they cannot be forged or that alteration of the data cannot occur undetected.

<span class="mw-page-title-main">Letterpress printing</span> Technique of relief printing using a printing press

Letterpress printing is a technique of relief printing for producing many copies by repeated direct impression of an inked, raised surface against individual sheets of paper or a continuous roll of paper. A worker composes and locks movable type into the "bed" or "chase" of a press, inks it, and presses paper against it to transfer the ink from the type, which creates an impression on the paper.

Imposition is one of the fundamental steps in the prepress printing process. It consists of the arrangement of the printed product’s pages on the printer’s sheet, in order to obtain faster printing, simplify binding and reduce paper waste.

A wedding invitation is a letter asking the recipient to attend a wedding. It is typically written in the formal, third-person language and mailed five to eight weeks before the wedding date.

<span class="mw-page-title-main">Folding machine</span>

A folding machine is a machine used primarily for the folding of paper. Folding is the sharp-edged bending of paper webs or sheets under pressure at a prepared or unprepared bending point along a straight line according to specified dimensions and folding layouts. Paper can be folded with either a buckle or a knife; thus, there are generally three types of folding machines: buckle folders, knife folders or a combination of these two types. Whilst buckle folding is the more popular of the two methods, knife folding is sometimes preferable. Folding machine models vary in sophistication, with high-end machines capable of processing more complex folding jobs and unusual paper forms. Organizations required to undertake mass mail-out campaigns often employ folding machines to improve efficiency. However it is very commonly used finishing process across the printing industry.

<span class="mw-page-title-main">Galley proof</span> First proofs printed from type, usually before breaking into pages

In printing and publishing, proofs are the preliminary versions of publications meant for review by authors, editors, and proofreaders, often with extra-wide margins. Galley proofs may be uncut and unbound, or in some cases electronically transmitted. They are created for proofreading and copyediting purposes, but may also be used for promotional and review purposes.

<span class="mw-page-title-main">Origami paper</span>

Origami paper is used to fold origami, the art of paper folding. The only real requirement of the folding medium is that it must be able to hold a crease, but should ideally also be thinner than regular paper for convenience when multiple folds over the same small paper area are required.

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 newspaper production process begins with gathering news stories, articles, opinions, advertorials and advertisements to printing and folding of the hard copy. Usually, the news items are printed onto newsprint. The whole production process can be divided into four parts: Content gathering, Pre-press, Press and Post-press. The term production process should not be confused with manufacture as Production process is the stage at which many taxes are levied and collected in almost all countries. Manufacture is the stage at which the product becomes marketable and therefore the term also includes the stages of packaging and packing.
