PF SCREEN PRINTING 80 images FEBRUARY 2019 are 15 memory pre-sets, allowing the correct exposure time to be selected in seconds. 3. The typical exposure time on the V-Lux is 10-30 seconds, depending on the emulsion type. While waiting for the first screen to expose, the operator can set up a second job on the Spyder II. 4. The second screen is inserted in the V-Lux and the first screen is automatically pushed out the back of the V-Lux unit and onto the moving belt that transports it into the TigerClean Developer. 5. The dual pressure rinse jets in the TigerClean Developer station are said to produce “fast and dependable“ washout results. In initial testing, reports the company, screen washout times of around 60 seconds were achieved. 6. While waiting for the first screen to finish the washout, a third screen can be imaged on the Spyder – and so the cycle continues. This fully CE-compliant, automatic screen exposure and developing system has a vertical, space-saving design and includes a fast, optimised, ‘full array‘ UV exposure system that uses low energy LEDs. The closed process chamber eliminates water vapour in the screen room and special rubber flaps on the exit door Huddersfield-based Kippax has announced a new version of the Inpro TigerClean Developer system that is designed to directly complement the Spyder II computer- to-screen (CTS) and V-Lux exposure systems from Exile Technologies. The new system comprises a ‘docking unit‘ that converts Exile‘s V-Lux Upright UV Exposure cabinet into a fully in-line exposure and washout (developing) system. The modification to the V-Lux cabinet means that after being exposed to UV light in the V-Lux unit, the screen frame is then pushed onto a moving belt that transports it into the TigerClean Developer unit. The TigerClean Developer is a fully automatic screen washout machine that is said to be suitable for all types of artwork, including very fine linework and subtle highlight halftone dots. Fully automated workflow In a typical, fully automated workflow using the new Inpro TigerClean Developer with the Spyder II and V-Lux, the process would work as follows: 1. The screen room operator images a screen stencil on the Spyder II CTS. The typical imaging time for this is one minute or less. 2. The screen is then released from the Spyder and inserted into the V-Lux cabinet where it is exposed. There removes excess water to speed up the screen drying process without damaging the hardened emulsion. For existing V-Lux users, the new system can be retro-fitted to their existing cabinet. “By adding a TigerClean Developer to a Spyder II/V-Lux computer-to- screen setup, the last labour-intensive element of stencil screen-making is removed,“ explains Exile Technologies. “The process becomes almost fully automated.“ It is, says the company, possible for a single screen room operator to run this in-line system, with up to 50 screens an hour said to be achievable. The new integrated system promises to save time and labour Kippax, Inpro & Exile Technologies: Automated In-Line Exposure and Washout System The new Inpro TigerClean Developer can be retrofitted to the V-Lux
