Tanji's Art Supplies will be continuing to manufacture the full range of canvases over the shutdown period. However, shipping and courier of orders is at this time unclear as our prefered shippers - PBT have indicated that Essential Services and distribution of materials from essential businesses have priority.

We will be able to fill local orders without any face-to-face contact. Please place your order either over the phone (07 579 9384), by email - using the contact page on this web site, or by using our on-line ordering facility. Once we have received your order, we will email you a invoice confirming the items ordered and the amount. Once the order has been made or completed, then we will notify you either by email or phone that your order is ready for collection - during this time, we will not be doing any deliveries.

Understandably, priority must be given to essential services and the distribution of essential products whilst attempting to keep everybody safe. Until further notice, we will be unable to ship any orders by courier or truck.

Large Format Canvases

Masterart is one of New Zealand's leading producer of very large artists stretched canvases. As a dedicated manufaturer of artists surfaces, we produce all of our own canvas supports in-house which means that we can customise our products to suit the requirements of our artist clients.

In New Zealand, the fine arts industry is quite unique to most of the rest of the world. New Zealand artist tend to want to spend their time painting or 'doing what they do best' which means that artist prefer to buy their surfaces ready to use without the time consuming requirement of having to assemble, stretch, size and prime their surfaces. Masterart Ltd has developed to become an expert producer of high quality artists surfaces, supplying to many of the leading artists in New Zealand, Australia and the Pacific Islands.

There is something special about really big artworks. While Masterart does produce stretched canvases up to 4800 mm long, most large format canvases are not that big. However, serious consideration needs to go in to the construction of large canvases as the stresses and strains of constantly adjusting tension needs to be accomodated.

The textiles utilised to produce Large format canvases need to be sufficiently strong to support the paint film. Masterart Utilises its own unique pre-primed canvases to produce large format stretched canvases that are designed to enable a degree of expansion and contraction.

Timber has been the material most commonly utilised to manufacture canvas supports. It is readily available and relatively cheap. However wood tends to have inherant properties that can cause issues such as twisting and bowing as a result of temperature or humidity fluctuations even quite some years after installation.

Masterart DURA-STRETCH aluminium stretcher bars are a uniquely designed canvas support made specifically to over come many of the issues that are related to timber stretcher bars. Because Masterart DURA-STRETCH stretcher bars are so much stronger and stiffer than traditional wooden frames, they are more suited to large format canvases. However, many New Zealand artists now utilise DURA-STRETCH canvases exclusively as they are ideal for shipping overseas without concerns for biosecurity issues and are suitable for environments that have high humidity or subject to large temperature and humidity fluctuations which can cause deformation and deterioration of the canvas.
