18x18 Vincent Pro Raw No 12 Canvas 7/8 Inch Deep #VR-1818

True 1:1 Square Proportion - 18x18 Size

The 18x18 square size is a little less common but gaining in popularity.

The square is perhaps the most intriguing proportion, as it is root of all of the other proportions. It is commonly used in both photography and art. Squares are typically used as the center canvas of a triptych or as a single canvas hung at a 45° angle. The square proportion is long used with medium format professional cameras, and most photographs we see on websites and social media are based on square images. Since all sides of the canvas are the same length, your eye is drawn evenly across the surface of the painting creating a sense of harmony, balance, and a generally a pleasing visual experience. The square format is also a good choice for artists who focus on geometric shapes or patterns in their work, as the regularity of the square shape can help reinforce these elements. Some artists enjoy the challenge of working within the confines of a square format, as it forces them to think creatively resulting in intriguing compositions.

Vincent™ Pro 7/8" Deep Bar • 5/16" Canvas Clearance

5/16" 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 Stretched Canvas Frame.

• Stretcher Bar Profile produces a 7/8" deep stretched canvas
• 1.5" wide Stretcher Bar
• Frames with a dimension of 16" and up have a groove machined in the center inside perimeter to which cross braces attach
• Solid Ponderosa Pine or Fir from the Pacific Northwest

What's so important about keyable canvas frames?

In dry and air conditioned environments, wood can shrink and canvas fibers elongate, thereby making the canvas looser to the point where you might see waves in the canvas. Keyability is an important feature that professionals cherish because it makes it possible to increase canvas tension without having to re-stretch it. There is a risk to re-stretching a canvas as it could apply undue stress on the paint across the surface which could accelerate cracking of the paint, particularly with oil paintings.

With Masterpiece's patented framing systems, you can tap the keys into the corners as well as the ends of the braces, which expands the canvas more equally across the entire surface. The difference between a loose or tight canvas is just 1/8", so even small adjustments with corner and brace keys can improve a stretched canvas.

To increase canvas tension:

1. Remove any staples in the corners above and below the canvas
2. Remove any staples that restrict the keys in the corners and braces
3. Tap all the expansion keys further into their respective slots until desired tension has been achieved
4. Using canvas pliers, tighten the canvas in the corners and staple
5. Canvas tension will be restored

Finger Jointed Wood is not meant for Stretcher Bars

Solid wood makes the most dependable Stretcher Bar, because one homogeneous wood member is going to behave similarly across the entire length of the Bar. Whereas, with finger-jointed wood is made-up of multiple pieces of wood, sometimes on the actual joint itself, presenting multiple points of failure which no one can control.

We only use Solid Wood to build our Stretcher Bars because a solid piece of wood will last indefinitely. When we speak of archival value, it's not just the paint you use and the quality of your canvas and ground, even the wood choices manufacturers add or reduce value to your final painting. The fact is, you don't want problems, and finger joints only increase that risk of the wood falling apart in the future.

The glue used to bind finger joints is a water based adhesive and when that wood is exposed to high humidity environments, particularly with exterior walls, the glue joints can give-up. 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.

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.

Biodiversity in our Forests is the Key to Life as we know it

By using lumber from sustainably managed forests in our products, we can ensure that the forests will continue to thrive and provide valuable resources for years to come. Sustainable forestry practices help to maintain the health and biodiversity of the forest, which benefits not only the environment, but also the local communities and businesses that rely on the forest for their livelihoods.

Specially Dried and Heat Treated Lumber

Our wood is handpicked from a curated group of environmentally responsible lumber mills in the Pacific Northwest. By adhering to our precise drying and heat-treatment standards, these mills produce lumber with nearly half the moisture you'd find in common home improvement outlets or lumber yards. This meticulous process not only enhances the wood's strength—minimizing risks of cracks, splits, or bends—but also elevates its dimensional stability. Such quality, despite its premium, is paramount in creating professional canvases designed to uphold the sanctity of your cherished art throughout the years.

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 Vincent™ Pro 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

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

One of the most celebrated features about Vincent™ Pro canvases is the patently robust framing system that makes it possible to increase the tension in the middle of the canvas, where the tension is needed the most. Our well-made keyable bracing system supports the canvas indefinitely. Braces prevent the stretcher bar frame from bowing-in so the canvas stays tighter long-term.

Painting is silent poetry, and poetry is painting that speaks. ♦ Plutarch

Plutarch, an ancient Greek biographer and essayist, had a keen understanding of the intricacies of human nature and the different mediums through which we communicate our deepest feelings. His writings, rich in historical accounts and moralistic tales, offer profound insights into the psyche of individuals from various walks of life.

Art and poetry, as observed by Plutarch, are interconnected realms of expression. While a painting captures a moment, emotion, or story without uttering a word, poetry breathes life into images through rhythmic language. Both mediums invite us into their world, asking us to feel, reflect, and connect. It's no wonder then that many artists have been inspired by poetic verses, and poets have found muses in visual art. By diving into either, we become part of a timeless conversation, transcending barriers of time, culture, and language. This symbiotic relationship between painting and poetry serves as a reminder of the boundless ways we, as humans, find to express the inexpressible.
