India’s Bureau of Indian Standards (BIS) is seeking public consultation on the first revision of its standard for poster colors, which are commonly used in commercial design and artwork. This revision aims to incorporate technological advancements and ensure safer and more reliable products for consumers by regulating the composition and lead content in products.
Lead Limit for Poster Colors
The poster colors should not contain more than 10 parts per million (ppm) of lead.
Content of the Composition
The poster colors should be a semi-viscous paste consisting of water-soluble or dispersible binders, pigments, plasticizers, and preservatives. The pigment should be finely ground and must not separate from the base substance, which typically consists of oils that help the paint to spread evenly.
Packaging and Labeling Requirements
Packaging requirements are also specified, with poster colors to be sold in securely capped glass or plastic containers of various sizes, including 15ml, 30ml, 120ml, 225ml and 450ml. Each container must be clearly labeled with essential information such as product name, color, net content, manufacturing date, manufacturer’s details or trademark, and batch number.
Detailed Color Range
The updated standard focuses on 26 specific colors, including magenta, turquoise green, carmine, mauve, dark green, pink, cobalt blue, permanent yellow, burnt sienna, prussian blue, lemon yellow, burnt umber, cerulean blue, yellow ochre, vandyke brown, ultramarine blue, orange, grey, light green, crimson lake, black, medium green, scarlet lake, white, deep green and vermilion.
This revision aims to protect public health by limiting harmful substances in widely used art supplies, ensuring better quality control and product safety for consumers.
