Pigments Checker New Version (2.1)

We released Pigments Checker v.2.1. We constantly add features to improve this tool:

It comes with our new Multispectral Imaging calibration card.
Commercial gray cards for photography cannot be used for multispectral imaging since they absorb near UV and violet radiation. We developed a gray card to cover the 400-1000 nm spectral range. It has 6 swatches, pure white, 4 grays and pure black. Their respective reflectance values are (%): 100, 80, 60, 40, 20, 0,5.

Take our Training program and Learn how to use the calibration card with our Multispectral Imaging system.

Rigid support.

We made Pigments Checker more durable adding a rigid finnboard support. We use a pure wood pulped paper (thickness 3 mm).



pigments checker v2 vsPigments Checker is for photographers, conservators and scientists interested in technical documentation of paintingss. It has 54 swatches of historical pigments designed for infrared photography, ultraviolet photography and other technical photographic methods for art examination. Check it out!

Pigments Checker is a collection of 54 swatches of his­tor­i­cal pig­ments that have been applied using gum ara­bic as a binder on a cel­lu­lose and cot­ton water­color paper, acids and lignin free. This paper is not treated with opti­cal bright­en­ers, it’s slightly UV flu­o­res­cent, and it reflects IR. Two cross-hair lines, 0,2 mm (ver­ti­cal) and 0.4 mm (hor­i­zon­tal) are printed on each swatch of paper before the appli­ca­tion of paint, in order to have a means to eval­u­ate the pig­ments’ trans­parency in the IR and IRR imag­ing. Among all the pig­ments and their vari­eties ever used in art these pig­ments col­lec­tion select the most used ones from antiquity to early 1950’.
