Printing Terms & Terminology

A sizes
Most common paper size used for general printing, stationery and publications.
See also: B sizes & C sizes

Acetate
A transparent plastic sheet placed over printed originals that are commonly used to protect books.

Against the Grain
Folding at right angles to the grain direction of the paper being used, as opposed to with the grain. This can cause cracking on heavier papers unless the paper is scored or creased.

Artwork
Finished layout or typesetting, drawings or photographs, made up in a form which is ready for the printer to print from.

B sizes
Size that sit between the A-sizes.
See also: A sizes & C sizes

Binding
The physical binding together of leaves of paper or board. There are various types of binding available – for example, saddle stitch, perfect, PUR, wiro, comb.

Bleed
Printing that extends to the edge of a sheet or page after trimming.

Blind Embossing
The process of stamping an image into the paper to produce a depressed effect on the paper surface, without the use of inks.

Block
Used to impress or stamp a design. The design can be blocked in coloured inks, or metal foil, including special effects such as holographic.

Board
Heavier paper (normally over 200gsm) which is usually used for products such as book covers and business cards. Generally, what most people might refer to as ‘card’.

Bulk
The thickness of a paper, normally measured in microns. ‘Bulky’ paper can beus eful, for example, for making publications appear larger without making them heavier.

C sizes
A paper size used for envelopes, designed to take ‘A’ sized paper.
See also: A sizes & B sizes

CMYK
Abbreviation for cyan, magenta, yellow and key (black),the four process colours commonly used when printing.

Capacity
Two creases close together to create a pocket or spine allowing the folder to take extra items such as leaflets or brochure. Normally between 3.5mm and 5mm.

Coated/Uncoated Paper
Paper with a coating improves reflectivity and colour holdout of a print. Gloss and satin are examples of coated paper. Uncoated paper is commonly used for the printing of letterhead and is also referred to a bond or offset paper.

Collating
Arrangement of printed sheets into the desired sequence.

Colour Separation
In photographic reproduction, the process of separating colour originals into the primary printing colour components.

Comb Binding
A plastic comb which is used to bind and grip the spine edge of a book.

Concertina fold
Folding each panel of a leaflet in alternate directions, so that when opened out the finished product is folded in a zigzag fashion.

Crease
An indented line pressed into the substrate to reduce resistance and allow folding without cracking or splitting.

Creep
In a saddle stitched booklet the bulk of the paper causes the inner pages to extend or creep further out than the outer pages when folded. When trimmed the inner pages are narrower than the outer pages, counteracting the creep.

Crop Marks
Lines near the edges of an image indicating portions to be reproduced. Also called cutting marks and tick marks.

Densitometer
A device for measuring the colour density at a specific location on film or printed product either by reflected or transmitted light.

De-bossing
Process of creating a 3D sunken image in paper.
See also embossing.

Desktop Publishing
The creation of artwork for print from your computer.

Die Cut
To cut irregular shapes into a paper or board using a die.

Digital Printing
Printing straight from electronic artwork (no plates used as in Litho print). Typically printed out of four colour process (CMYK). It’s ideal for short runs and faster turnarounds.

DL Envelope
A standard envelope size measuring 110mm x 220mm. They take A4 sheets folded into three.

DPI
Dots per inch that indicates the resolution an image. The more dots per inch, the higher the resolution and the better quality the image.

Drill
Drilling of holes in literature which will allow insertion or a treasury tag or into a ring binder.

Dummy
Mock up of an intended product to give you an idea and feel for the finished item. A dummy will be made with the correct paper and materials.

Duplex
A term referred to when you print on both sides of a sheet of paper.

Embossing
Process of creating a 3D raised image in paper.

Encapsulation
Where a printed matter is sealed in a plastic coating providing a rigid, watertight covering.

Finishing

Printers’ terminology for the accurate positioning of one colour with another on a printed sheet. Also known as register or registration.

Folio
Technical printers’ term for the page number.

Font
A set of letters, numbers or symbols that share a unified design. The design is called a typeface.

Four-colour process printing
Process of combining four basic colours to produce a full-colour final product. A plate is created for each of the four colours in a full-colour job (cyan, magenta, yellow and black (key). The colours are then printed one at a time using lithography and combine to produce the full variety of colours that we see on the finished product.

FSC

A reflective, shiny coat on coated paper, for example, glossy magazines.

Grain Direction
The direction that the fibres in paper become aligned during manufacturing.
 
GSM/Grams
The unit of measurement for paper weight (grams per square metre).

Landscape
A design where the width is greater than the height – (opposite of portrait).

Litho / Lithography
A printing process by which the inked image to be printed is transferred (offset) first to a rubber blanket layer before coming into contact with the paper which takes up the inked areas. This process is normally used for longer runs/larger quantities of a printed matter.

Make-ready
All activities required to prepare a press or other machine to function for a specific printing or bindery job. Also called setup.

Matt paper
Dull coat on paper, the opposite of glossy.

Microns

onto the paper.

Overs
The number of surplus copies printed. Almost inevitable using litho.

Overprinting
Printing onto a sheet which has been previously printed.

Pages (pp – printed pages)
Normally one side of a leaf in a publication – for example an A4 sheet folded in half to create an A5 leaflet would have four ‘pages’.

Pantone
Standard range of colours denoted by a number. Using pantone inks (as opposed to four-colour process) provides a greater variety and more accurate colour when matching spot colours across products. If your brand requires a very specific colour, then you may wish to use a pantone colour (spot colour) in addition to CMYK.

Perforating
Taking place on a press or a binder machine, creating a line of small dotted wholes for the purpose of tearing-off a part of a printed matter.

Personalisation
Where data elements are unique to an individual printed piece. Concept facilitated by digital printing.

Screen printing
Method of printing where ink is forced through a fine mesh and a stencil. Screen printing is particularly suitable for large display posters or for printing onto unusual surfaces such as T-shirts.
