A term used for coated papers.

The images/text that are to be printed (usually supplied digitally as a PDF). As a general rule, artwork should be supplied as a high resolution PDF at 300 DPI with crop marks and 3mm bleed.

Changes made by the customer, usually at the proofing stage. These are sometimes chargeable.

Larger than A-sizes, most sheet-fed print presses take these paper sizes. It then allows for trimming to A-sizes

B0 – 1000 × 1414 mm
B1 – 707 × 1000 mm
B2 – 500 × 707 mm
B3 – 353 × 500 mm
B4 – 250 × 353 mm
B5 – 176 × 250 mm
B6 – 125 × 176 mm
B7 – 88 × 125 mm
B8 – 62 x 88 mm
B9 – 44 × 62 mm
B10 – 31 × 44 mm

To print on the reverse of a sheet which has already been printed on one side.

Where the image to be printed extends (usually by 3mm) over the crop marks. This makes trimming easier and means the finished documents will run to the edges.

A type of embossing where no ink is used. Instead, the design or text is only visible as a raised area on the paper/card. Also see de-bossing which has the opposite effect.

Where a design is stamped into the cover, usually in a metallic foil.

Strong, uncoated paper often used for stationery.

Thickness of paper measured in Microns, as opposed to the weight see GSM.

A method similar to perfect binding where the text pages are glued in to the cover. In burst binding, slots are cut in to the sections to help the adhesive.

Paper sizes used for envelopes. These correspond to A-sizes (e.g. C4 envelope will hold A4 sheets)

C3 – 324 x 458 mm
C4 – 229 x 324 mm
C5 – 162 x 229 mm
C6 – 114 x 162 mm
DL – 110 x 220 mm (holds A4 folded twice)

Abbreviation of Cyan, Magenta, Yellow and Black. These make up the standard 4 colour process used for printing in full colour.

Paper which has a coating on one or both sides. This can have a gloss or silk (matt) finish. Coated papers are used for the majority of printed products, but not for stationery where an uncoated (or bond) paper is used.

See sealing

Where a line is scored to allow for easier and tidier folding. Any board over 170gsm in weight will need to be creased before folding.

Lines marking where the paper is to be trimmed after printing. These should be part of the artwork.

The custom made cutter used when die-cutting.

Where an image is pressed or stamped into the paper creating a depression as opposed to an embossed, raised impression.

Where an irregular shape is cut from the paper instead of trimming square edges. This can be any shape but requires a die or cutting forme to be made up specially.

Proofs printed digitally. These are suitable for checking layout and pagination but not for colour. The reason being they will be printed on different paper and/or using a different machine to the finished product.

Low cost method of printing best suited for short run jobs. It works directly from electronic data without the need for printing plates. This makes the process very quick but the print quality, although a good alternative is not on par with Lithography but gaining ground as technology advances.

Envelope size to hold an A4 sheet folded twice (or a compliment slip). 220 x 110mm.

Dots per inch, or the image resolution. For print, all images in a document should always be a minimum of 300dpi.

A paper back cover with the text pages glued in (see perfect binding & burst binding).

Where holes are drilled. This is essentially hole punching but on a larger scale.

A Mock Up of the finished product. This can be printed or unprinted, depending on the purpose. See proofs.

Where designs are pressed in to the paper to leave a raised effect.

Where printed material is fully enclosed and sealed in plastic. This leaves a small, clear plastic border around the sheet where it is sealed. Encapsulation is durable and water resistant.

The size once trimmed and folded.

The size before folding, after trimming. Can also be used if a product is to be supplied creased but unfolded.

There are a large number of different folding options. Some common folds are:

  • Concertina or Z fold
  • Gate fold – where left and right edges fold to the centre
  • Roll fold – like a takeaway menu.

Forest Stewardship Council is an independent, non-governmental, not for profit organisation established to promote the responsible management of the world’s forests. Certain paper brands are accredited by the FSC.

Printing in CMYK, as opposed to using spot colours Although you can print full colour with additional spot colours.

These papers have a smooth surface and a high shine, perfect for producing printed promotional items e.g brochures, flyers and leaflets.

The direction of the fibres of paper. It is easier to fold with the grain.

Grams per square metre. This is the standard measurement of weight for paper.

The pages of the artwork are arranged such that after printing, cutting and folding, the pages will be in the correct order. Sometimes seen when an imposition proof is supplied electronically, the pages will not be in chronological order.

To die-cut the top layer but not the backing of a two layered sticker/label.

Where a thin plastic film is fixed to one or both sides of the paper. This can create a silky matt or a high gloss finish, depending on the intended purpose and personal preference. It also acts as a protective barrier if the print needs to be more durable or is likely to encounter a demanding environment.

Where a document is oriented so the long edges are at the top and bottom. As opposed to portrait.

The most popular print process, a metal plate is treated so that the image area attracts the oil-based inks, while the wet non-image areas resist them.

All work associated with setting up the print press before production.

See Dummy.

The files to be printed which make up the artwork Usually a print ready PDF.

One side of a sheet of paper. For example, an A4 sheet has 2 pages. An A4 sheet folded in half to A5 has 4 pages.

See Spot colours.

Portable Document Format. Universal file format which combines images and text.

Where the text pages are glued in to the cover. See also burst binding and drawn on covers.

Pantone Matching System. Followed by 3 or 4 digits to make up a code e.g. PMS 072. See Spot colours.

Where a document is oriented so the long edges are on either side. As opposed to Landscape.

Printed pages. Refers to the number of pages in a document e.g. 12pp (12 pages).

Proofs are an example of what is to be printed so both parties are in agreement. Any errors or amendments should be picked up at this stage. This can take the form of a digital proof, usually supplied as a PDF, or a printed proof. See digital proofs and wet proofs for more details.

Where a document is wire stitched on the spine, better known as stapled.

The oldest method of printing. Ink is applied to a porous silk screen and passes through a stencil or template to leave an impression. Normally used when printing on fabric and banners and when printing on board that is too thick to pass through a standard litho print press.

A coating applied over the print to fix it. This helps prevent set off and smudging.

Where the cover and text pages are on the same paper stock.

This is where the ink from one sheet is transferred on to the reverse of the sheet above. Leaving ample time for the ink to dry and applying a sealer helps to prevent this.

A sheet-fed printing press uses individual sheets, instead of continuous rolls of paper used on web offset presses.

Silk papers have a low surface shine, a smooth finish, but not glossy.

Refers to solid colours which are found in commercially obtainable colour ranges such as Pantone®, these are mostly used in addition to CMYK where CMYK is not available e.g. Printing gold or silver. When using Pantone colours, it is worth bearing in mind for future jobs that should you want to print in CMYK, the chosen Pantone® may not have a suitable CMYK equivalent, which may in turn lead to the expense of using additional plates.

A high gloss finish applied to specific areas of print. This differs from gloss laminating which has to cover the whole sheet.

Paper which has not been coated, not gloss or silk.

A method of printing which uses a continuous roll of paper. They are very fast presses and are only suitable for large print runs on relatively thin paper stocks.

This is a fully made up, printed proof. The same machine and materials will be used as for the finished product. Whilst this is quite expensive, it does leave you with an exact mock up of what is to be printed. This is suitable for colour checking. Only recommended for large runs and specialist items.
