If your image or background colour is to print right to the edge of the paper, we require 3mm extra on each edge. A4 finished size is 210x297mm, so A4 BLEED size is 216x303mm. We will trim 3mm from each edge to give you the required finished size. (Ensure text or images are not too close to edge).


This is the thickness of the paper on which your artwork will be printed. Often referred to as “weight” it stands for “Grams per Square Metre”. Standard weight for A4 copy paper is 80gsm, Business Cards is usually 300-350gsm.


RGB Colour

RGB stands for Red, Green, Blue. These are the colours used by electronic screens such as televisions, computer monitors and mobile phone screens. By overlaying these three colours as small dots a full colour image appears on the screen. By default most work created in Microsoft applications such as Word is RGB in colour.

CMYK Colour

CMYK stands for Cyan, Magenta, Yellow and blacK. These are the colours used in printing: both digital and offset printing. By overlaying these four colours as small dots a full colour image appears on the printed sheet. The dots are created by ink (offset printing) or powdered toner (digital printing) being applied to paper or card.
CMYK colour viewed on a monitor or screen is converted to RGB colour.


The Pantone Colour Matching System® enables printers throughout the world to have a precise method of reproducing an exact colour tone. Pantone inks are solid colours, mixed from base inks very much like mixing a tin of paint. It allows corporates such Coca Cola to have the same red used throughout the world.


DPI (dots per inch) refers to the output resolution in printing which is typically 300dpi with artwork at same size to printed item. Images from the internet are usually in the range 60-90dpi and often unsatisfactory for printing.

Paper Sizes?

In Australia paper sizes are measured in metric. A4 is 210x297mm, while US “Letter” is measured in inches (81/2″ x 11 inches) which translates to 215.9×279.4mm. This will affect margins when “Letter” artwork is printed on A4 paper. Typically metric paper is referred to A0 (841x1189mm), A1 (594x841mm), A2 (420x594mm), A3 (297x420mm), A4 (210x297mm), A5 (148.5x297mm), etc.


Invented by Adobe Systems and perfected over 20 years, Portable Document Format (PDF) is an open standard for electronic document exchange. It is preferable to convert your file formats (Word, Excel, PowerPoint, Publisher, etc.) to a “Press Quality” Adobe PDF file before forwarding. A word document can change its attributes when opened on a different computer to the computer on which it was created.

Offset vs Digital printing?


Offset printing uses CMYK (aka Process or Full Colour) and Pantone spot colour (PMS). This process uses ink and plates to transfer an image onto paper. It produces high quality cost effective results for long print runs. A single page A4 brochure would require a minimum quantity of 1500 copies to be cost effective via offset. A colour proof is generated from the approved file to be checked before printing commences, however it is not printed on the chosen stock, so final colour matching is still made ‘on press’ as the job is run.


Digital printing can print both CMYK and RGB, although here at Print Plus we only print CMYK. Short runs of any quantity less than 2000 copies are typical for digital printing. As a digital printer requires no printing plates, there is less time and expense involved in setting up a file to print. This means that a finished file can be proofed and final quantity run within a short time period. Proofs are also able to be printed on the final stock choice for accurate colour checking.

Which process?

The differences between the two processes can decide how to print certain jobs. Price based on quantity required and available time are obviously key considerations, but as offset offers the ability to specify PMS colour, this may be the better choice to achieve the desired result. However here at Print Plus we are able to match PMS colours quite accurately on digital prints. While offset printing still often results in slightly better quality prints, digital methods are being worked on at a fast rate to improve quality and lower costs.

Large Files?

The size of files that can be sent via email is dependent on the service provider. Typically up to 10MB may be possible. As a service for our customers, Print Plus will receive your multiple files up to 2GB via


Consider adequate margins to allow for binding (usually minimum 10mm). We suggest equal margins left and right for double sided pages to optimise back-up.

Laminate vs Celloglaze?

Laminate can offer a thicker plastic protection than celloglaze, but laminate generally requires a sealed edge beyond the page size, whereas cello glaze can be trimmed to page edge.

Ring Binders Capacity?

Based on 80gsm sheets of paper the following capacities are available: 19mm (150 sheets); 25mm (200 sheets); 38mm (300 sheets); 50mm (450 sheets); 65mm (600 sheets).
