Matboard Products

White Core is a high quality mat designed for framers who want the impact of a bright white bevel that will not discolour but do not require the qualities or costs of conservation matboard. With a range of over 220 references in colour, size, texture and designer finishes, PETEBORO WHITE CORE will help you meet all your designing challenges.

It has a unique construction with each component buffered to a pH of 8.2 +/-0.5% and containing a minimum 3% reserve of calcium carbonate to provide years of stability.

The Surface Paper

On over 85% of the Whitecore references Peterboro uses the same Conservation grade surface paper found in the conservation line. The surface paper is buffered and lignin free. It has a high strength quality to minimize surface tearing during cutting.

Core

The core is pure white and has been buffered against acids to ensure bright white bevels and v groves for years to come. The specially designed fibre morphology and density specifications means Peterboro Whitecore cuts cleaner and results in smoother bevels.

Backing Paper

Peterboro is the only company to use high quality conservation backing paper on all our white core. The tensile profile keeps the boards flat and resists tearing while cutting.

Quality

Peterboro WHITE CORE line has one of the highest specifications in the market. The result is a superior mat that will stand the test of time, resisting the effects of acid degradation and remaining bright.

The Core

Peterboro uses high grade virgin Alpha Cellulose as the main ingredient in the conservation core. Alpha Cellulose can be distilled from cotton or wood, the higher the Alpha Cellulose content the higher the purity of the board. Peterboro specifies that PETERBORO CONSERVATION core must have more than 90% Alpha Cellulose, industry specifications call for no less then 84%.

Chemical Ingredients

The conservation quality of a mat can often be affected by the chemical impurities within its materials. For instance the level of iron and copper within the matboard can create tarnishing and discoloration of the mat while the sulphur content can raise acidic levels that attack both mat and artwork. In the manufacture of PETERBORO CONSERVATION Peterboro strictly controls the level of chemical ingredients to ensure that they meet or exceed the PPFA and Fine Art Trade Guild standards for chemical composition.

Surface Paper

To reduce color fade and bleed PETERBORO CONSERVATION uses pigments for surface paper coloration. Peterboro pigments are specified to meet or exceed the fade and bleed test requirements outlined by the Fine Art Trade Guild and PPFA standards. Independent testing shows that PETERBORO CONSERVATION exceeds these requirements.

Backing Paper

Peterboro backing paper is 100 % virgin fiber, buffered with calcium carbonate at a 3% minimum reserve, no optical brighteners, and a smooth finish with even coloration. Peterboro backing paper meets or exceeds the standards as set out by both the PPFA and the Fine Art Trade Guild.

Quality

Independent QC benchmarking shows that PETERBORO CONSERVATON has one of the highest standards of consistent quality in the market.
