With this arrangement, the system and method enables the virtual wear article to stretch, flex, sag, etc., on the virtual model to better approximate the real-life fit and look of the wear article on an object during design of the wear article.

A photo resist composition contains a polymer resin, a first photo acid generator (PAG) requiring a first dose of actinic energy to generate a first photo acid, and a photo base generator (PBG) requiring a second dose of actinic energy, different from the first dose, to generate a photo base. The amounts and types of components in the photo resist are selected to produce a hybrid resist image. Either the first photo acid or photo base acts as a catalyst for a chemical transformation in the resist to induce a solubility change. The other compound is formulated in material type and loading in the resist such that it acts as a quenching agent. The catalyst is formed at low doses to induce the solubility change and the quenching agent is formed at higher doses to counterbalance the presence of the catalyst. Accordingly, the same frequency doubling effect of conventional hybrid resist compositions may be obtained, however, either a line or a space may be formed at the edge of an aerial image. Feature size may also be influenced by incorporating a quenching agent into the resist composition that does not require photo generation.

A method and apparatus for determining a digital signature from an article made of paper, cardboard, plastic or many other material types.
