Style of Painting: The main difference between a quality thangkha and a commercial one is in terms of proportion. In a quality thangkha the dimensions are perfect and correspond accurately to instructions given in the sutras (Buddhist texts)
Quality paintings in most cases are shaded in 'Kamdang' style (dry shading), while commercial thangkhas are shaded in 'Lemdang' style (wet shading). 'Kamdang' can be clearly identified as small horizontal strokes of paint in the sky and on the hills, and as small soft dots of colour on clouds and flowers. It is a long procedure where a square inch of area could take perhaps a day to be filled. Lemdang can be identified as a smooth gradation of colour and is quickly accomplished. The outline of the eyes, face, fingers, and feet in quality thangkhas are detailed, accurate and perfect. The commercial paintings will not have such details. The halo of the deities for quality thangkha painting will have a perfect circle whereas some irregularities can often be found in commercial paintings. The gold decoration on the painted surface of a quality thangkha will shine when tilted against light whereas the artificial gold on a commercial thangkha will not.Field: The traditional paithani has a coloured silk (sometimes cotton) field; 'the field contains a fair amount of supplementary zari patterning'. The field is now commonly woven of pure silk; earlier, silk and metal (gold thread) end-panels (pallus) and borders were sometimes woven separately and attached to fabrics of pure cotton.
Borders: 'The borders are created using the interlocked-weft technique, either with coloured silks or zari'. 'A wide band of supplementary warp zari (in a mat pattern) is woven upon the coloured silk border. In borders woven with a zari ground, coloured silk patterns are added as a supplementary-weft "inlay" against the zari....'
Endpiece: The end-piece has 'fine silk warp threads...[and] the weft threads are only of zari, forming a "golden" ground upon which angular, brightly coloured silk designs are woven in the interlocked-weft technique, producing a tapestry effect.'
