File types we use

Crop Marks are guide marks added to artwork to indicate where the printed sheet will be trimmed down to it's required final size.

Bleed refers to the extension of artwork beyond the 'crop marks' to ensure the printed image runs to the edge of the finished piece and doesn't fall short of the trimmed edge.

This refers to typeset text that's been converted to 'outlines' thus rendering it as graphics and no longer editable text — this eliminates the need to supply the fonts used when sending us your documents / artwork to print from. It also saves time at our end by not having to install the fonts used to enable us to process your files for print.

CMYK (Cyan, Magenta, Yellow and Key [Black]) is the description for four-colour process printing whether lithographic or digital, commonly used for printed materials that include images, photographs or documents with multiple colours.

RGB stands for Red, Green, Blue and these are the colours your computer monitor projects to display colour images on the screen.

The Pantone® Matching System (PMS) is the most widely used system for specifying ink colours. Pantone® colours are also known as spot colours and are used when a specific colour is required, e.g. our logo is in two Pantone® colours. PMS 433 is our grey and PMS 324 is our blue.

There are 1,755 spot colours in the Pantone® Matching System, the majority of them are referred to using a three- or four-digit number followed by a C or U. There are also a small number of named colours, such as the 18 base colours like Pantone® Reflex Blue C or Pantone® Orange 021 U. The letter suffix refers to the paper stock on which it is printed — a C indicates coated or glossy paper and board or a U indicates uncoated paper and board.

Yes, we can make amendments to the files you supply if they are in an editable format and all of the associated fonts and graphics are present. Please see our list of file formats and software applications.

Given the vast number of digital files we receive everyday, we do not have a policy of keeping your supplied artwork on file. However, we will gladly archive your files if you specifically ask us. We also retain supplied artwork that has required intervention on our part or for any other reason to retain the files for future use.
