Pura Smooth is a 300gsm matte fine art paper with a luxuriously smooth surface ideal for high resolution photographic imagery. It is able to produce extremely crisp and accurate detail as a result of its leadership (when measured against other fine art papers on the market today) in tonal range value, line quality, line contrast, and raggedness.

Pura Smooth is Breathing Color's latest innovation, tailor-made for the demanding and discerning photographer who values superior print quality and the best longevity available.

Key Features

UNRIVALED COLOUR GAMUT - With a proprietary inkjet receptive coating that delivers exceptional numerical readings in dmax and colour gamut, Pura Smooth represents the new age of fine art papers from Breathing Color.

DELIVERS EXTREMELY DEEP BLACKS - The dmax on Pura Smooth is exceptional. If you print black & white photography, this paper is a must see.

BEAUTIFUL SKIN TONES - Just wait until see your portrait photography on Pura Smooth. It might be the most pleasing reproduction of skin tones you have ever seen on a fine art paper.

INCREDIBLE RESOLUTION - Pura Smooth will bring a new perspective to the finest detail contained in your photographs. Photographers spend a lot of money to buy the right camera and equipment that will enable them to capture every detail of their vision. It's time to use a paper that can do the same.

OBA-FREE, YET STILL BRIGHT WHITE - Called "Chromata White", this breakthrough technology has set Breathing Color apart for years. Normally, OBA-Free products have a yellowish surface. Our "Chromata White" technology, which we released in 2005, forever changed this by delivering OBA-Free with the desired white surface. This answered the needs of our customers to maximise the longevity of their prints while maintaining the most popular and desired look. Pura Smooth delivers a bright but slightly warmer white than the bright cooler white Optica One which does contain OBA's.

WATER RESISTANT FOR LAMINATION - Pura Smooth will accept a water based liquid laminate or water based varnish and is compatible with Timeless laminate allowing users to display their fine art prints without glass. See how here.

How should I handle Breathing Color media? What about storage? 

To prevent the transfer of oils and dirt from your hands to the inkjet receptive coating of the media, white cotton gloves should be worn when handling the media. When not using the media, you should store it in its original packaging, exactly how it was shipped to you. Read more about our recommended handling and storage best practices on Breathing Colors blog, The Art of Printmaking.

How long should I let my prints dry before coating/framing?

When printing on canvas or fine art paper, it is critical that the prints be allowed to dry and outgass fully before they are coated or framed behind glass. Typically this takes 24 hours. Finishing these prints prematurely can cause a whole host of problems from splotchy glass when framing, to pin holes and bubbles while coating in preparation for stretching. Read more about dry time and outgassing on Breathing Colors blog.

What is a safe way to clean my coated fine art prints?

Cleaning fine art prints that are coated with our Timeless or Glamour II varnish is quite easy. Simply use a damp cloth to gently wipe the surface of the coated print to remove dust or dirt. Read more about cleaning your coated fine art prints here on Breathing Colors blog, The Art of Printmaking.

How can I remove edge curl from my fine art prints?

Edge curl is something that most users have learned to deal with, but there are ways to remove it. We have found an easy and affordable method for flattening your prints. The best part is you can use supplies you already have in your print shop! Here are the supplies you'll need:

- An empty 3" core (save the core from your last roll of fine art paper)
- 2 sheets of foam packing material
- Tape

I am seeing "banding" on my prints. What is causing this?

There are a few different things that can cause banding. Most commonly, you will see banding occur when there is a clogged nozzle or something else hardware related. Please follow the steps below to help identify the issue:

Ensure that your printer can handle the thickness of the media you are attempting to print on. In your printer's user manual, or by calling the manufacture, you can find the maximum weight that your printer will accept; make sure that the media doesn't exceed this maximum specification.

See Breathing Colors blog about doing a nozzle check and other maintainance on your printer.

If the nozzle check results look fine, proceed to check your platen gap settings and making sure other print settings are correct.

Testing & Evaluation - Trial Rolls 

For testing and evaluation, we offer short trial rolls of all of our inkjet canvas, inkjet fine art paper, inkjet decor paper, and inkjet signage products that are sold at cost. Typically, trial rolls are 17"x10 feet. The purpose for this is to allow our customers to conduct a comprehensive evaluation of our products, cost effectively. There are several steps that should be taken when testing any new digital substrate for your printing business.

1. The substrate should be tested with several different images to be sure the product performs well with everything image-type that you intend to use it for (try a portrait photograph, a vibrant fine art print, a black & white piece, etc.). Make sure you are selecting images that are fairly different from one another with respect to color and tonal gradation for a thorough evaluation.

2. Show a few of your most important customers a print of their own work on the media you are testing. Maybe provide an example of your current media to illustrate a comparison. Explain the physical and archival attributes of the new substrate and the reasons that you are considering a switch. It is the printmakers job to educate their artists about all things printing-related, especially media.

3. Trial rolls provide enough media to create custom profiles, for those who are capable. Breathing Color also offers a free custom profile service, which requires approximately two square feet of printed media.

4. It is important to have enough media to leave a margin for error in case the first attempt had not been printed correctly (print settings, profile, platen gap, etc.).

5. For inkjet canvas: coating, stretching, and hand embellishment should also be tested.

Matte Black vs. Photo Black

Matte Black (MK) ink is designed for Matte Papers and Photo Black (PK) ink is designed for glossy papers. The difference between these two black ink types is simple; MK prints a very dull, flat black, while PK prints a highly glossy, shiny black. Think in terms of flat black spray paint vs. glossy black spray paint. Generally speaking, the very best results and the deepest blacks for that particular substrate will be achieved by using PK with glossy substrates and MK with matte substrates. Your Epson printer manual will also provide you with a decent explanation of when they recommend using matte black ink or photo black ink.

That being said, wide-format Epson printers present a problem for those who wish to maximize their output potential by offering both matte and glossy papers as available substrate options. This is because Epson machines are built to run either the PK or the MK, rather than allowing the printmaker to switch blacks from print to print. As a result of this quandary, those who own wide-format Epson printers must make an important decision What type of prints do I want to be best at? In other words, if 80% of your printmaking business is fine art on matte papers and matte canvases, naturally you will want to run your Epson with MK, which will render the highest black density on your primary substrate line. Likewise, if you are a photo lab for example and mostly reproduce photography on glossy papers, the PK is the more intelligent choice as it will render the glossiest black, which is most desirable on glossy substrates (to avoid a gloss differential).

Traditionally, most all inkjet printable substrates, matte or glossy, will work with the PK ink. Though the maximum black density (DMAX) would be significantly less, the print is otherwise unaffected. This is not true of the MK ink. When most glossy or semi-glossy papers are introduced to the MK ink, the ink will run and bleed, rendering the print completely unusable.

Inkjet Fine Art Paper - General Information

If you are selling fine art gicle prints your quality driven customers will demand using an acid-free pH-neutral archival inkjet fine art paper. Museums and fine artists with rigid standards will require this class of fine art paper. So if you are looking for a wide format media you can trust, Breathing Color fine art papers have become the most popular solution for fine art printmakers and publishers worldwide. 

There are several good reasons to use the fine art papers available from Breathing Color. First and foremost, your business requires nothing less than the best quality paper available so that your customers are guaranteed to maximize potential colour gamut and dmax. 

Cheap papers are suitable for normal printing for pictures to share with friends and family and also have their use for proofing pictures you intend to print for sale or display on more expensive materials.

Choosing a Surface of a Fine Art Inkjet Paper

You may not like the particular inkjet fine art paper surfaces that you have tried thus far, which could have been the papers you received with your Epson printer. Although the range provided by, for example Epson, is large enough to be confusing, the fine art papers included in it actually only cover a fairly small range of what is available. Using fine art papers from a "third party manufacturer" gives you a much wider choice, including many different smooth and textured inkjet papers and shinier gloss finishes as well as some unusual materials including some non-paper surfaces including fabric such as an inkjet printable silk as well as signage and inkjet banner products such as adhesive vinyl. All of these fine art inkjet papers are available at much more competitive prices and are, in many cases, superior in performance.

Choosing a Weight of a Fine Art Inkjet Paper

The traditional measurement of fine art paper thickness is given in grams per square meter (gsm). Normal typing paper is around 80 gsm, and typical inkjet fine art papers may range from 120-310 gsm. More expensive fine-art papers are usually on or over 300gsm, while the lesser expensive ones are on or below 210gsm. Heavier fine art papers can cause problems with the paper feed in some printers. Small-format models that have a significantly curved path for the paper through the machine are particularly unlikely to be able to use such heavyweight papers. However, despite what the printer manual says, usually double the maximum weight specified with some printers will print fine art without problems.

Archival Qualities of Inkjet Fine Art Paper

Three factors - paper, ink and paper coating - interact to determine print lifetimes, as well as the environmental factors including storage and display conditions. Good fine art papers are likely to lead to longer lifetimes, and as with most other media, this generally means acid-free materials.

Cheaper fine art paper generally will not last well, breaking down over time to give acidic materials that will attack the image. Acid-free papers usually perform better.

The best fine art papers are generally made from 100% cotton rag rather than wood pulp, and these tend to be expensive - at least a dollar for a sheet.

Inkjet Fine Art Paper Confusing Issues

There are actually relatively few manufacturers of high quality papers. The distributors sell many papers made by some manufacturers under different brand names, which makes for some confusion. Claims by some of these re-branders that they specify different coatings for the paper they sell often - if not always - appear to be untrue. The aim of this re-branding is to lock the user into using paper supplied by them, when the same material (but under a different name) may be available more cheaply elsewhere. Breathing Color does not participate in such a strategy and our customers appreciate the exlcusivity and uniqueness of our product line.

Glossy Inkjet Fine Art Papers

Gloss papers are generally made for non-archival use. They range from highly reflective plastic films to materials with a relatively low gloss, that are almost closer to a pearl or lustre finish.

Pigment printers seldom produce good results on gloss surfaces, often giving very slow drying and patchy results.

How do optical brightener additives (OBA) effect longevity of fine art prints?

Optical Brightener Additives (commonly referred to as OBA's) are widely used in paper coatings, textiles, and laundry detergents to increase the perceived "whiteness" of the treated products. OBA's work by absorbing light from the (invisible) ultra-violet end of the spectrum and emitting light in the (visible) blue/white range of the spectrum. This shift in the frequency of light energy, results in a whiter and brighter appearance of the treated product.

Many digital inkjet printmakers, who print using Epson 9800, Epson 7800, Epson 4800, and/or Canon imagePROGRAF iPF9000 prefer a bright white surface to print on, to the true surface color of their naturally-yellow substrate. As a result, paper manufacturers are adding OBAs to the digital inkjet receptive coating (IRC) used on their fine art papers and inkjet canvas'. The reflection of white light emanating from the OBAs will completely overwhelm the paper's natural color, creating a higher perceived whiteness, which artificially enhances the maximum color gamut and black density of the printed image. Popular rag papers that contain OBAs are the Hahnemuhle Photo Rag, Somerset Velvet, and Breathing Color Elegance. These papers are known for their bright white surface and excellent color gamut and black density.

While OBA's appear to be an effective solution for enhancing the whiteness and overall image quality of inkjet paper, this conclusion is slightly premature. The fact is, that OBA's can pose a serious threat to the integrity and longevity of a fine art print by accelerating metamerism and causing color shifts, and yellowing over time. Let us explore each of these issues in further detail.

What is metamerism? Harald Johnson defines metamerism as a normal phenomenon relating to how the human eye perceives color. It occurs when "two different color objects have the same color appearance to a normal human viewer under one light source (metameric match) but look different under another light source (metameric mismatch)." (*1) To a printmaker, this means that the painstakingly precise color information applied to each print will be compromised whenever that print is viewed under a different light source. Thus, one primary goal of any printmaker should be to avoid metamerism in order to validate the time spent on color management and to uphold the integrity of the reproduction. After all, what good is a reproduction if it does not closely match the original?

Now that we understand metamerism and why it should be avoided, how do OBAs fit into the picture? When OBAs are exposed to UV light, the treated paper appears brighter and whiter. When OBAs are not exposed to UV light (in the evening), the OBA's "lose activity", causing your eye to actually see the paper color without OBAs - which will look creamy or somewhat yellowed. This amount of "OBA activity loss" will vary constantly depending upon how much exposure the paper has to UV light. Picture the lighting conditions inside of an art gallery and how they will change depending upon the time of day. This will have a subsequent effect on the art itself, as it is exposed to various levels of UV light throughout the day. For example, your print could be displayed in a gallery near a window where direct or indirect daylight may be illuminating the print. In a case like this, where there is a high UV component, inkjet papers that contain OBA's will strongly fluoresce and will appear bright white. However, in the evening when the same print is displayed with low or non-existent UV component (or incandescent tungsten illumination), the OBAs will not fluoresce, making the paper appear yellow, therefore causing your eyes to see the image color differently.

How does this happen? Think about it. Your "bright white" paper is profiled to your printer so that the computer can translate color information accurately to the substrate. Anyone with experience creating color profiles will tell you that the "white point" of your substrate is an integral component of a profile's accuracy. If the whiteness of your paper changes, so must your profile. This is precisely how OBAs are constantly working against your color management. As the perception of whiteness of the paper is constantly changing, so do the perception of colors. Here's a good test. If you can find a paper offered in both bright-white and natural-white, try using the natural-white paper printing profile on the bright-white paper. You will be surprised by how different your results will be.

Next, take both papers and observe the whiteness in broad daylight. The paper with optical brighteners should look extremely bright white, while the paper without optical brighteners will look creamy. Then, take the two papers indoors where they are exposed to no sunlight and observe the whiteness. You probably will not be able to tell a difference between the two. At the very least, you will notice that the paper with OBAs no longer looks so white and bright. Many times, the OBA-Free paper will appear whiter. Nevertheless, the important point is that your OBA-Free paper has remained consistent under both lighting conditions, while the paper with OBAs has been inconsistent. This inconsistency directly correlates to the inconsistency that your image color will have under different lighting conditions. Still, overall white point is only one of the risks associated with using substrates that contain OBAs.

Another problem with OBAs is that they have been known to decompose over time and can cause yellow stains to appear on your prints. It is possible to avoid this issue with UV inhibiting products and overcoats that are designed to reduce the UV activation of OBAs, but their effectiveness in this regard has yet to be proven. Therefore, regardless of the post-print protective coating that can be applied, the fact remains that any fine art print made on a paper manufactured with OBAs is a print at risk. To quote Henry Wilhelm from the Wilhelm Research Institute, "When long-term image permanence is an important consideration - or may eventually become an important consideration - fluorescent brighteners should be avoided".

This associated risk is precisely why OBA-Free papers have rapidly gained popularity in recent years despite their "Natural White" color, which could be considered creamy or even yellow. Of course some printmakers have chosen to use OBA-Free papers because they specifically like the warm tone of the paper, but the majority of the market is avoiding papers manufactured with OBAs because they (1) enhance metamerism and (2) they are a potential risk to the longevity and integrity of a substrate. A few examples of popular OBA-free papers are Epson's Ultrasmooth Fine Art Paper, and Breathing Color's Sterling Rag 210.

Printmakers who use OBA-Free papers simply eliminate the entire element of what can be called "OBA-associated Risk" from their business. These printmakers know that metamerism is a problem that should be minimized whenever possible - certainly never enhanced. Furthermore, OBA's have degradation potential and up to this point there is no guarantee that anything will last. Nevertheless, if an artist or photographer specifically requests that their artwork be printed on a paper manufactured with OBA's, a disclaimer should be issued, clearly explaining the facts and associated risks. Ultimately the customer should be left with the decision of how they want their art to look.

In an industry so obsessively tied to color accuracy and long-term print stability, it is a wonder why OBA-Free papers are not more commonly used than papers manufactured with OBA's. Art sells because of how it looks and in this business there is no room for error. Therefore, anyone who is involved in this relatively infant industry of selling printed art has genuine incentive to make color integrity a top priority. As further research is performed on the subject of OBA's, this industry will become more educated which will most likely cause a shift towards the widespread use of OBA-Free papers.

It is for this reason that Breathing Color has been conducting a great deal of research and development in quality paper manufacturing, which has resulted in the latest technological breakthrough "Chromata White". The Chromata White technology allows Breathing Color to create a highly stable white base paper/canvas without the use of harmful OBA's or any other fluorescent brightening additives. Color shifting is reduced by stabilizing the whiteness of the base substrate with a special anti-oxidation technology that even further protects printed images. Furthermore, metamerism is minimized by quenching the ultraviolet excitation wavelengths resulting in a more stable illumination of an image under different spectral power distributions.

By using Chromata White inkjet papers and canvas', printmakers now have the opportunity to get the best of both worlds. They eliminate all OBA-associated risk, and they have bright white surfaces to make beautiful prints that uphold the highest standards of color integrity that are possible today.

When stacking coated prints what kind of interleaving paper should I use?

The best way to protect coated prints when stacking or sending out to ship would be to wrap the print in Glassine paper. You do not want to separate your prints with paper that contains acid in it. If acid comes into contact with your print it may cause the print to turn yellow. You can find many different types of Glassine papers online, or at your nearest art supply store. The main thing to keep in mind when looking for this type of paper is to make sure the paper has a neutral pH level, or acid free.
