Acid free paper
It can be made from any cellulose fibre as long as the active acid pulp is eliminated during processing. … Acid-free paper addresses the problem of preserving documents and preserving artwork for long periods. Acid-free papers are good for archival purposes and won’t turn yellow or fade over time.
Paper intended for permanent records and usually subject to a specification covering strength and chemical properties.
Basis weight of Paper
The basis weight or grammage is basic physical property of paper and paperboard. The Basis weight of paper is calculating by the weight per unit area. It is mainly expressed as GSM (grams per square meter)
The substance (gsm) when paper becomes known as board varies a great deal between manufacturers and can vary from as low as 200gsm to as high as 400gsm. The lower substance definition usually refers to text paper.
Bulk & Bulky Paper
Bulk is applied to the GSM, feel and thickness of a paper.
Chain of Custody
Tracing the origin of the product from forest to end-user. i.e it starts from the forest (origin of the tree ) – pulp mill- paper mill- paper supplier-customer and – end-user. The chain carried by invoice, when ownership passes from one person to another.
Do I need to use only recommended media on my digital machines?
Some OEM’s only test limited papers prior to launching their digital machines and only list those to their customers. More often than not there are many alternatives if not the same quality under a different name. It is against the trade practice act that OEM’s can’t stop you using the alternative products which are similar quality.

What does FSC certified paper mean?
FSC® certified paper is paper that has been harvested in a responsible manner. … FSC is an acronym for the Forest Stewardship Council®, which is an independent, non-governmental, not-for-profit organization that was established to promote the responsible management of the world’s forests
What does PEFC certified mean?
The Programme for the Endorsement of Forest Certification (PEFC) is an international, non-profit, non-governmental organization which promotes sustainable forest management through independent third party certification. It is considered the certification system of choice for small forest owners.
What is bleaching of paper?
1The primary reason for the bleaching of pulp is to remove the lignin content since it causes a brown discolouration in the final paper.
What is the difference between coated and uncoated paper?
Coated papers are papers that are coated with glossy, semi-gloss, or matte finishes. Coated paper has an agent added to its surface in order to improve brightness, smoothness, or other printing properties. Once coating is applied to the paper, rollers help to “polish” the paper. It fills in the tiny pits and spaces between the fibres, giving it a smooth, flat surface. Coating makes the printed material more shiny and bright, which is why it is typically used for brochures, glossy photos, booklets, and more. It is more resistant to dirt, moisture, and wear, which will help it to last longer.
Uncoated paper does not have a coating to fill in between the fibres. It is generally rougher than coated paper and tends to be more porous, which makes it very absorbent. Images printed on uncoated paper will be softer and less crisp. Uncoated papers are great options for novels or books that you will be writing in.
What is the difference between FSC and PEFC?
FSC® sets specific standards that have to be met by suppliers in the timber trade. PEFC is an umbrella brand incorporating different national certification schemes. The end goals of both bodies are the same. Both provide schemes to protect forests and ensure end users get the responsibly sourced timber they requested.
What is wood free paper mean?
Wood Free” is a confusing term used for a long time in the paper and printing industry. It is really a shortened description of “Mechanical Wood Free“. Mechanical wood paper is made from trees mechanically ground up to make fibres small enough to make into paper. Some chemical bleaching is also applied to this pulp but fibres still contain Lignin, the natural polymer that fills the spaces between the wood’s cell walls (Wikipedia has a good article on Lignin). Lignin is brown in colour so paper made from mechanical wood is usually a brownish white. Newspapers, paperback books and some magazines are made from paper using mechanical wood. On exposure to light the brownish colour develops and becomes stronger so this type of paper is only really used for products intended for a short lifespan.
The woodfree paper contains no unbleached mechanically ground wood fibres. All the fibres in the papers have the lignin and other impurities removed by bleaching with a chemical. Chemicals used are either hydrogen peroxide, sodium hydrosulphite which are less harmful to the environment. Chemical bleaching adds costs to the paper but the whiteness of the paper and the fact that it is less likely to discolour over time make it desirable for many applications. So, your paper is certain to contain wood pulp but not unbleached mechanically ground wood.
All our papers are woodfree paper, less likely to discolour over time make it desirable for many applications.
