18x72 3D Pro Grenoble Canvas 3-1/2" #DG-1872

True 4:1 Super Panorama Proportion - 18x72 Size

This dramatic 18x72 size is in the 4:1 Aspect Ratio.

The 4:1 Super Panorama proportion has gained interest with a lot of artists, providing even a more dramatic and eye-catching compositional format. The unusual proportion provides the artist with a unique perspective with which to tell their story on canvas. This proportion is called a "polyomino proportion on the order of 4", or a linear tetromino object.

3D™ Pro 2.5 Stretcher Bar • 1/2" Canvas Clearance

1/2" Canvas Clearance is the space between the Bar and the canvas. Generally speaking, more clearance reduces the risk of the canvas touching the wood and creating unsightly lines during painting. Our design provides the optimal clearance so as not to impact your painting, but still leaving enough wood to the maximize strength of the Stretcher Bar.

• Produces a 2.5" deep stretched canvas (Actual depth is slightly thinner)
• 1.25" wide Stretcher Bar
• All Bars have an exclusive groove on the inside perimeter of the frame to which cross braces and Diamond Corner Braces attach
• Solid Ponderosa Pine or Fir from the Pacific Northwest

No Finger Joints!

Solid Wood is far superior to finger jointed wood, which is many small pieces glued together, each with varying grain densities that absorb and shed moisture at varying rates, expanding and contracting non-uniformly as environmental conditions change, and causing the wood to bow and the finger joints to eventually fail.

A single homogeneous kiln-dried solid wood Stretcher Bar outperforms and outlasts a finger jointed Bar whose sole purpose is to save the manufacturer cost, not contribute to the archival value of artwork intended to last a millennium. As a manufacturer, Masterpiece® does its part to conserve as much wood as possible, and still provide a quality product that will out-perform any other in the marketplace.

18x72 2.5" Deep Edge Heavy Frame Offers Maximum Support!

• Drawing depicts the exact frame construction, not the proportion
• 2.5" Deep Edge K2 Heavy Stretcher Bars are precision machined with a unique double tongue-and-groove corner joint that provides rock-solid torsional rigidity that resists warping or twisting, which is an important benefit for such a deep edge canvas
• Two parallel 3/4" thick super strong keyable braces (3.25" wide) provide excellent frame support for this 18x72 size - Braces are permanently installed in the frame, but canvas tension may be increased by tapping-in the keys or wedges that slightly expand the size of the frame
• The Stretcher Bars have an proprietary utility groove on the inside perimeter of the frame which is used to attach braces and other optional frame supports
• The Masterpiece braces feature an exclusive system that allows you to increase the tension to the middle of the frame, where the tension is needed the most; it's so unique it earned us a patent
• To increase canvas tension: 1) remove any staples in the corners and those that retain the brace keys in the middle, 2) tap all of the expansion keys further into their respective slots, 3) tighten and re-staple the canvas in the corners

Canvas Tension is in Your Control

In dry climates or air conditioned environments, the lack of moisture in the air causes wood frames to shrink and the canvas fibers to narrow and elongate making the canvas more slack and resulting in a loss of canvas tension. In some instances, the canvas could have waves on the surface resulting in an unsightly viewing experience.

Our 3D™ Pro 2.5 professional frames provide the functionality for you to slightly expand the size of the frame in the corners and the middle of the canvas, thereby increasing canvas tension all across the surface. The difference between a loose canvas and a tight canvas is just 1/8" of an inch, so a small adjustment using our corner and brace keys makes an important difference in canvas tension.

• Helps to prevent waves that occur in a loose canvas
• Increase canvas tension by tapping-in the corner and brace keys
• True professional class canvases make it possible for you to adjust the canvas tension

Cross Braces Make it Tighter

A tightly stretched canvas on an un-braced frame overpowers the Stretcher Bars causing them to bow inward and thereby lose tension. Sometimes that bow can expose a space in picture frames.

When a canvas is stretched on a properly supported frame, the cross-braces prevent the Bars from bowing thereby achieving maximum canvas tension. To increase the canvas tension even more, simply tap the corner and brace keys further in their slots. Properly supported frames provide you with the control over the canvas tension of your canvas and painting.

Sustainable Forests for Future Generations

Sustainable forestry practices go beyond just planting and harvesting trees. They also involve careful planning, monitoring, and management to ensure the long-term health and productivity of the forest. By using lumber from sustainably managed forests, we can support these important practices and help to ensure that our planet's forests remain healthy and productive for generations to come.

Specially Dried and Heat Treated Lumber

We source our wood from a select group of top-tier environmentally conscious lumber mills in the Pacific Northwest. These mills specially dry and heat-treat the lumber to our specifications, resulting in about half the moisture content compared to wood from typical home improvement centers or lumber yards. This process makes the wood stronger, reducing the likelihood of cracking, splitting, or warping. While the wood we use comes at a higher cost, it ensures a more dimensionally stable end product. This stability is crucial for crafting fine professional canvases that support your invaluable art over time.

MuseumWrap™ Stretching Technique

With more than a half a century of American engineering, Masterpiece® designs and builds its own proprietary stretching equipment that enables us to produce the finest and most tightly-stretched canvas on the market.

• Drum-tight stretch!
• Up to 50% tighter than other methods
• Balanced tension across the surface
• Uncut folded corners make it possible to remove and re-stretch canvas on the same size frame
• Usually the corner folds are on the long sides

Simply touch one of these impressive canvases and the quality of our materials, workmanship, and design will be immediately obvious to you, and to those who will ultimately acquire your art. The canvas you select becomes the foundation of your painting. Your reputation depends upon the quality of your artwork and the integrity of your material choices. Savvy art buyers and art enthusiasts place a higher value on artwork made with quality materials because they expect their investment in your art will last hundreds, if not a thousand years. Using quality paints and a well-made canvas is an investment in your legacy and your brand.

Let's go to Tahiti! But not to sketch, we'll go just to be there. ♦ Paul Gauguin

Paul Gauguin's exclamation about Tahiti captures more than just a desire to escape to an exotic location. It embodies a deep yearning to immerse oneself in an environment, to experience it fully, rather than merely observe it from an outsider's perspective. Tahiti, for Gauguin, wasn't just a place; it was a state of mind, an opportunity to be free from societal constraints and to embrace a different way of living and seeing.

We often seek inspiration from the world around us. We travel, we observe, we immerse ourselves in different cultures, hoping to find that spark. Yet, Gauguin's words remind us that sometimes, it's essential to simply be present. Not every experience needs to be captured, sketched, or painted. Some moments are meant just for us, to be felt and lived. In our fast-paced art careers, taking the time to truly immerse ourselves in our surroundings without the pressure of creating can refresh our perspectives and reinvigorate our passion.
