The 21 x 21 cm square is highly popular. It corresponds to a DIN A 4 format (210 x 297 mm), cut to a square.
Strength: 1,5 mm
The most popular material thickness for a bevelled passepartout. In combination with most paper thicknesses of pictures, it fits into any type of frame without having to adjust the insertion depth of the magnetic frame individually.
Color Cardboard: White
The brightest of our three white colours. With its optical brightener, white is the ideal cardboard colour tone for offset and similar papers with a high degree of whiteness. If your paper is rather warm-toned, antique white or natural white is usually recommended.
The passe-partout is a museum cardboard with a window opening made to measure, manufactured with a bevelled cut. In terms of design, it puts the picture in the centre and creates a distance between the picture and the glass.
A passepartout allows the work to unfold on multiple levels. At the same time it prevents the object from touching the glass. A carefully carried out bevel cut at the inner edges gives it more depth and avoids shadows. The distance to the frame makes the framing overall larger. A thick passe-partout intensifies the effect. HALBE only uses certified passe-partouts by KLUG Conservation. They are ageing-resistent, protect the art and give it a more valuable appearance. The cutting with one or more cut-outs is done according to your requirements (up to 1800 x 2500 millimetres).
