Block printing has become popular because the simple process can create intricate designs in rich and vibrant colors. Bagru printed fabrics were once only making use of organic colours and vegetable pastes which are eco-friendly, skin-friendly, fast, and retain their brilliance for most of the lifetime of the fabric. Time and easy availability have caused a shift in the use of colors which now include the use of chemical or man-made dyes.
The fabric is printed with natural dyes or colorants which are derived from plants and animals. Different blocks with different colours are used for the different parts of the overall design. Since a majority of the natural dyes are from plants, Bagru Prints are also referred to as ‘eco-friendly’ prints. The primary colours are available from the following substances. Blue is available from Indigo, with desired shade got from increasing the concentration or diluting it. Green is available through indigo mixed with pomegranate. Red is through the Madder Root, while yellow is from turmeric.
After the fabric is completely block printed it is dried and later put in vats of boiling water containing alum and other agents. The solution with fabric in it is constantly stirred to prevent sticking to any portion of the vessel. The process is complete with the fabric being washed again to remove excess colour and any other sticking impurities.
