Red River Aurora White and Natural are our recommended replacement for the well-missed Museo Artist Cards, which are unfortunately no longer being imported into Australia. This heavy weight, 100% cotton fine art card stock imbues your prints with a classic, high quality feel perfectly suited for illustrative works and all types of art reproduction. This is a perfect choice for those looking for the fine art look and feel.

The Aurora surface structure is comparable to traditional rag matte fine art papers, smooth and velvety to the touch with a slight texture much like the classic Hahnemühle Photo Rag. This card is 100% archival with no added optical brighteners, giving it a creamy, warm white tone.

Aurora is coated on both sides of the paper, making it suitable for double-sided printing. Due to it's thickness, we recommend purchasing our Red River Card Sample pack to check its compatibility with your home printer. You can also check the list of compatible printers with Aurora on the Red River Papers website.

Red River Aurora is ISO 9706 and ANSI Z 39.48-1992 certified (Permanence of Paper for Printed Library Materials) which means the colours in your printed image will stay vivid and unfaded for many decades if suitably cared for.

Red River Aurora cards come pre-scored for an effortless fold.

(N.B. Accessories are only available in 100 packs).

Please note: Specifications are provided as a guide only.

We try very hard to keep these up to date and correct, but if a particular specification is really critical to you, then please double check the specification directly with the manufacturer. Some features may of course have caveats not fully described here.

To get more information about a particular specification, use the arrow to get a 'Specxplanation'.

  • Construction
    Fibre Based

    Described simple, papers are constructed in two main ways:

    Resin Coated papers are the 'modern' approach. These use less fibre and replace the fibre with resin (a nice name for plastic). This means these papers are relatively cheap, strong and robust, but tend to be less attractive to the touch, and accept less ink. They tend to have a clinical appearance and it's hard to write on the back of them. They tend to be popular in the consumer and wedding/portrait markets. Important to note: these papers are difficult or impossible to recycle because of their plastic content.

    Fibre Based papers are traditional papers made without plastic, using only plant fibres. These tend to accept more ink and have a more attractive appearance, and these are the papers most of our customers favour. These papers are fully recyclable and we thus strongly recommend you use fibre based papers whenever possible.

  • Substrate
    100% Cotton

    What is the paper base made from?

    Possibilities include:

    • Wood Pulp - the most common and cheapest
    • Alpha Cellulose - the best part of wood pulp, separated. Generally tested as archival as cotton etc
    • Cotton - the most common fine art paper fibre
    • Bamboo - an ecologically friendly alternative to cotton
    • Mulberry & more - many other plant fibres can be used to make archival paper
  • Acid Free?

    Is this paper acid free?

    Acid in paper leads to earlier yellowing and the paper will also become brittle more quickly. Thus for a paper to be archival, it needs to be acid free.

    Papers which are not acid free are generally best used for proofing (test printing), and shorter term purposes. That is, they are not considered to be a fine art level product, or suitable for print sales into the art or professional photography markets.

    This does not, of course, mean these papers will vanish or discolour overnight - they generally still have life-spans suitable for commercial work and above or on par with e.g. typical photo chemistry papers. They are thus suitable to markets like signage, or the decor market (e.g. print sales for kiddies bedrooms, for example) - but should be avoided if you're trying to sell your work as a serious art level product.

    In general, papers made from cotton are naturally acid free, which is one reason they are often favoured. Other fibres, like Kozo, are also naturally acid free. High grade wood pulp papers can also be made to be acid free, however, if the lignin/acid is removed from the pulp.

  • Coating

    These days almost all papers are microporous coated - meaning they'll accept inks from both dye based and pigment printers well.

    In years past, some papers had a swellable coating - designed to give a greater life to prints with dye based inks but this approach has fallen out of favour.

  • Paper Weight
    300 gsm

    In 'gsm' - grams per square metre.

    Not, technically, the same as paper thickness, but obviously correlated. The heft of the paper. European art papers are traditionally generally around the 300gsm mark. Asian papers historically tended to be lighter, 100 to 200 gsm.

    Papers with a higher GSM tend to have more opacity, i.e. you see less through them.

  • Thickness / Caliper
    18 mil

    The thickness of the paper, as supplied by the manufacturer. Also known as Caliper (as calipers are used to measure this value).

    Unit are in millimetres (e.g. 0.5mm, half a millimetre), or microns/μm = micrometre, or thousands of a millimetre. I.e. 500 microns (μm) = 0.5mm.

    (Note in many ways this a much more relevant figure than the more often quoated gsm - as it is thickness of a paper, more than weight, which determines how easily a printer feeds a paper).

  • Surface Texture
    Matte, Smooth

    What is the surface texture of the paper?

    We divide this into six groups. We go by the appearance of the actual paper and not what the manufacturer might label the box with!

    • Matte - smooth and texture
    • Gloss - semi, gloss, and high gloss
    • Double Sided - special case papers that are printable to full quality on both sides.
  • White Tone

    What is the white tone of the paper?

    • Cool White - a paper with a distinctly cool (blue) tone
    • Bright White - A paper that is brighter than non brightened papers, but not overly cool
    • White - a natural clean white tone for an art paper - most Photo Rag papers fall here
    • Warm - a distinctly warmer, creamier paper
    • Pearlescent - a distinct warm grey tone (generally found only with metallic papers)
  • Optical Brighteners?

    Does the paper contain chemicals in it to brighten its appearance?

    We're using the value/description the manufacturer supplies (see also the White Tone and White Value specs).

    In many cases, only a small amount is used to even out batches of cotton, and then only in the paper base, not the coating - in these cases, it is generally agreed such use of OBAs is essentially insignificant and will not materially impair the archival life of the paper.

    More on this here.

  • Compatible Inks
    Pigment Inks (use matte black)
    Dye Based Inks

    What ink type (dye and/or pigments) can you use with the paper?

    Also, if using pigment inks and you have a choice, should you use the Matte Black or Photo Black ink?
