Standard Paper & Envelope sizes
The International Standard paper size standard (ISO 216) is used by most of the countries worldwide. It is a metric-based system with a consistent ratio (approx.: 1:1.4). Each size can be Folded or cut evenly into smaller half sheets. The benefit is that printed materials can easily be reproduced in different sizes without having to crop or change the layout of the item being printed. This optimizes costs by allowing use of the entire parent sheet and prevents excess paper from being wasted.
A series
most common series used in Australia these sizes are all relative to an A4 sheet of copy paper.
B Series
used less these days this is an imperial system used mainly in the USA but can be useful for special projects.
C Series
Reserved mainly for envelopes. as They are slightly larger than the corresponding A series. e.g. a C4 envelope will fit an A4 piece of paper inside without folding.

High Quality Printing Specifications
How to save you files with the minimum requirement to ensure your work is of the highest quality
All images should be converted to CMYK and have a resolution of atlas a minimum 300dpi at the final size of output.. this usually means that the original image would be either a higher DPI and enlarged to fit or a lower DPI but a much larger size reduced to fit.
Most internet images are 72dpi and not usually suitable for high quality output.

Bleed & Trim Explained
To ensure a perfect result with any print job, it is important to add 3mm "Bleed" to your artwork. Bleed is required for any image or graphic element that butts up to the edge of a page. By extending these elements past the "trim" this will compensate for any microscopic movement in the paper due to distortion from the printing process or from the slight drag that occurs when a 100mm stack of paper is cut in the guillotine. Designers must ensure that any graphics or part of a photo that need to remain on the printed item, does NOT extend past the trim, rather just a part of the image that will be trimmed off to insure the overall quality of the final product.
