CAPILLEX CP GRAPHICSCREEN
27 May 2003 - Autotype International
| In process printing, the shape of the screen-printed dot is a key factor in determining the quality of the finished printed article. Unfortunately, it is a fact of life today that many screen printers are still struggling to achieve perfect dot control with fine halftone images.

One exception though is Graphicscreen, a well-established graphics printer with a workforce of 22 employees and just a stone’s throw from Antwerp in Belgium. Luc Lambregts founded the company in 1987 in Mortsel and Graphicsreen soon became a leading supplier of graphic products in their region. Luc started to print four-colour process with solvent-based inks. Although at that time they mainly printed 90 lines/inch, some of the finest halftone images required were at 133 lines/inch and depending on the colour density required on the Polystyrene, PVC or cardboard substrate a 120, 165 or 180 threads/cm polyester mesh was used. In 1999 Graphicscreen abandoned solvent-based screen inks, due to environmental and health and safety reasons, deciding to adopt UV-curable inks. This solved the health and safety problems, but introduced the challenge of controlling ink deposit to reduce skipping and dot gain. Luc attempted to control the problem using conventional capillary film, but the problem of inconsistent print quality remained. It was only when Luc was introduced to the revolutionary new Capillex CP from Autotype that things started to improve. Capillex CP is ‘Controlled Profile’ stencil specifically formulated for ultra fine halftone and line printing. The low stencil profile and optimised Rz-value give superb dot reproduction and sheet to sheet reproducibility was finally achieved. Due to the low stencil profile, ink deposit was kept as low as possible and did not cause skipping and other dot distortion problems. 'A dot looks again like a dot', says Luc Lambregts. As part of their on-press control a standard control strip is printed and now the increased print consistency allows effective corrections to be made using a spectro-photometer. 'This was just not effective when using the other capillary film system due to the sheet to sheet variations caused by skipping', summarises Luc. 'Thanks to Capillex CP, we achieve a consistent and reliable print quality for jobs of 2,000-3,000 prints and we have no hesitation in increasing the line ruling up to 133 lines/inch. In fact, now the criteria for making a decision for either digital or screen printing is not based on print quality, but on print size and quantity.' Where quality and consistency are paramount, you can trust Capillex CP from Autotype.
