Abstract: A method for producing an article which is made of a transparent material and devoid of visible surface lines consists in producing a substrate which is made of a transparent material having a refractive index , whose at least main face is machined and polished in such a way that the Ra value thereof ranges from 0.001 to 0.1?m, but has visible surface defects in the form of thin individual scratches, in deposing, a liquid polymerisable composition of a masking coating, whose contact angle with said substrate main face is equal or less than 30° and which is formed by polymerising a masking coating having a refractive index such as 0.01
