A technique where graphics, including text, are made to look smoother and so better looking and easier to read. The intensity of some pixels are adjusted to fool the eye into seeing a smooth line.

Auto Density Control
Auto Density Control helps the printer maintain consistent colour.

Auto Trapping
Trapping creates an overlap between adjoining areas of colour. This compensates for registration problems when printing the C, M, Y and K planes of an image. Auto trapping can be switched on and off in the printer's PostScript driver.

Banner Paper
Long sheets of strong paper to allow for bigger printing. Usually used for making a statement, organisation charts, flow charts, statistics and planners. Banner paper is available in both A4 and A3 widths

Bind Margin
An increased margin that accommodates the reduction in paper area when a document is bound.

Black Finish
Black Finish is a printer driver option that controls the way in which black is printed in colour documents. There are two options, true black where black toner is used to print black and composite black where equal amounts of Cyan, Magenta and Yellow toner are used to print black. True black is best used for text whereas composite black is best us…

Black Overprint
Black overprint is when 100% black text is printed over a coloured background without removing the coloured background from behind the text. Black overprint is used to prevent registration problems where a white space can appear around each character.

Bleed
When a printed area extends beyond that required then this is called a bleed. 1) Print outside required area so that, once trimmed, the image extends to the edge of the paper. 2) Overlay colours to minimise any registration issues.

Booklet Printing
Booklet printing refers to a feature where the printed document mimics the format of a book. To do this the pages within the document are re-ordered allowing the printed sheets to be folded to create the book. When printing large documents in booklet format the signature option should be used to create a manageable amount of paper to be folded. Ple…

Chromability
In-house colour printing made easy from Oki. Chromability is about making it easy for everyone in your office to produce professional results in colour.

CMYK

Collate
In a printing context, collate refers to printing pages of a document in their correct order.

Colour Registration
The CMYK (cyan, magenta, yellow and black) printing process uses overlapping inks of cyan, magenta, yellow and black. To produce the best possible output, the colours must print in specific positions so that overlaps are accurate. If the colours are not aligned, the resulting print may appear to be blurred, or have white space around text or produc…

Consumables
In printing terms, consumables or consumable items refer to parts of the printer which have to be replaced once their life has expired. For example, a toner cartridge is classified as a consumable item.

Crop
This is where the edges of a picture or page are trimmed or cropped to make it fit a certain size or to generally just remove unwanted parts of an image or page.

Crop Marks
Markings indicating where cuts should be made e.g. to trim unwanted margins or to separate business cards.

DPI
Dots Per Inch. The number of pixels or Dots per inch of an image. This is also known as 'resolution'. The higher the resolution, the better the quality of print.

Driver
Software that allows your PC to communicate with an external device e.g. a printer driver converts output to the correct format for a printer to produce an image.

Driver Setting
Refers to the options you have set for your printer in the printer driver. For example you can configure the printer to always print on both sides of the paper.

Duplex printing
Print on both sides of the paper.

Duplex Unit
The part of your printer that allows you to print on both sides of the paper i.e. duplex printing [not all printers can print duplex and a duplex unit may need to be purchased separately and installed.]

Gutter
A printing term for space left between two items on a page. E.g. between left and right pages, between columns of text.

Halftone
Halftone refers to the process used to arrange printed dots on a page to simulate shades of either colour or grey. For example when the number of printed dots within an area is higher this creates a deeper colour.

HDD
Some Oki printer models include a Hard Disk Drive (HDD) which can be used to store fonts, templates, overlays as well as being used to store print jobs.

Hue
Hue is the wavelength of light reflected or transmitted from an object. However, hue is more commonly known as the actual colour, such as red, yellow, or blue.

Job Offset
Job Offset is where each printed document in the printer's output tray is offset to either the left or right of the previous printed document allowing each document to be easily identified.

Landscape
In printing terms, Landscape is used when describing the paper orientation. In this case the width of the page is greater than the height.

LED Technology
Oki's printers are electro photographic printers where a light source shines light on a light sensitive drum creating an attractive charge like a magnet. Toner is then attracted to this charge and then transferred to the paper and finally fused in place. The light sources employed by Oki printers are known as Light Emitting Diodes or LED's for shor…

Media Check
Media check is a function that checks that the paper size selected with the print job matches the size of paper in the printers paper tray. If the size does not match, an error message is displayed on the printer's operator panel.

Memory
Oki's printing devices contain various types of electronic memory which provide various functions: RAM - Random Access Memory. The printer uses RAM in a similar way as a PC uses RAM. When the printer receives a print job, the data is stored in RAM while the printer processes it. Certain functions like DUPLEX printing and printing banners are memory…

MFP
In printing, MFP is a commonly used term to represent Multi Function Products which are devices that that have more than one function such as being able to print, scan and fax.

A page description language (PDL) specifies the layout and contents of a printed page. Hewlett Packard's Printer Control Language (PCL) and Adobe's Postscript are the two most commonly used PDLs.

Pagination
Pagination has numerous meanings but in general it refers to defining where separate pages are formed within a document and how they are formatted.

Paper Tray
Paper tray refers to the area within a printer where the paper is stored. The input tray is where the blank paper is stored before printing whereas the output tray is where the printed documents are stored.

PCL
Printer Control Language was developed by Hewlett-Packard to allow applications to control their printers. PCL has also been adopted by other printer vendors including Oki.

PDF
PDF (Portable Document Format) is an electronic file format developed by Adobe. PDF files retain the same formatting as the original document and can be viewed by Adobe Acrobat Reader without the need for the original application.

If equal amounts of red, green and blue are applied, the human e…

Saddle Stitch
Saddle Stitch refers to a finishing process, where the sheets of paper are folded and secured by applying staples along the fold to produce a book format.

Saturation
Saturation represents how pure a colour is. It is the amount or strength of the colour. Saturation is measured as a percentage from 0% to 100%. If a colour has a saturation of 0% then the colour will contain no hue and would appear grey. On the other hand, if the saturation of a colour is 100% then the colour will appear fully saturated.

Secure Print
Secure printing is where a PIN (Personal Identification Number) can be assigned to each print job sent to the printer. The user has to enter the PIN number into the printer's operator panel in order to have the document printed. This feature is useful when a confidential document needs to be printed on a shared network printer. To use this function…

Signature
The signature function is used in conjunction with booklet printing. The spine of a book is made up of numerous smaller booklets which are then bound together. For example, if you fold a sheet of A4 paper in half you can create 4 pages of A5. The signature option limits the amount of pages used to print individual booklets in order to make folding …
