Dust starts on the ceiling and works its way downward. The tops of light fixtures, walls, shelving units and everything else outside your field of vision collects dust. Starting with the ceiling, dust everything, and allow it to settle before sweeping the floor, and use a sweeping compound to avoid recirculating the dust. These tools are available with either a washable polymer roller or a roller wrapped in adhesive film that is removed after it becomes dirty to expose fresh adhesive. Keep humidity levels as high as possible or at fixed levels.
Humidity dissipates static because the microscopic water droplets act as ionizing agents.
Though misting systems are rarely necessary for screen printers, keeping humidity levels high can help. If one skid of materials runs better than another, and humidity levels are nearly the same, then by process of elimination, you can start ruling out other problems. It is important that printers and suppliers are conscious of each others' needs. If your film converter, for example, is introducing static into a product during sheeting or slitting, you and the supplier need to pinpoint the source and solution to the problem. However, in a quality-conscious industry, finding the happy medium between what is doable and what is too costly is often necessary.
