摘要 |
<p>Production of identical particle distribution images comprises visualizing a real lead particle distribution using a known chemographic method, digitizing and binarizing the distribution image, using the binarized image for adjusting a screen printing mask and applying the distribution onto material using a standard screen printing method using a polyvinylalcohol displaced with finely ground lead particles. Preferred Features: Nitrocellulose particles are used in place of lead. Other screen printing base pastes are used in place of polyvinylalcohol.</p> |
