Standardization is a key part of preventing costly quality-control issues on press.

The same general procedure also applies to the separations for the DTS imaging system. The primary difference here is that there is no film to check, so you must be 100% confident that the art is correct prior to sending it to the DTS to ensure that the image being applied to each screen is correct from the start.

The screenroom
The best time to design and engineer a screenroom is during the startup period of the facility. It is at this point that you must determine the required amount of space needed for current production, as well as the amount of additional space needed for future growth. Keep in mind that the screenroom you are currently designing may not only need to double its output in time, but also serve multiple shifts. Therefore, the original design of your screenroom may seem excessively spacious—but with any increase in growth, that space will be used in short order.

Another key element in regards to designing a good screenroom is to plan the environmental aspects into the design. The simplest means for maintaining the proper environmental conditions within your screenroom is to have the screen area added onto the central air system that you use to air condition your office work space. Attempting to use room-air conditions is generally a bad idea because it will dramatically increase the relative humidity and, as a result, hinder the screen-drying process after reclaiming or coating.

Screenroom layout
The layout of the screenroom should be designed for a smooth and even flow of work orders through the department. You do not want people backtracking or, in the case of multiple screenmakers, getting in each other’s way.

The screen department should be broken into individual work areas/rooms if possible. The flow of work passing through the screen department should start with the screen-drying area as the first stage. The department needs to be kept as dust-free as possible, which is why the first area should be used for the screen drying that takes place following screen reclamation. This area can also be used as storage for clean, uncoated screens.
