3M Dynapro ET 350 Monitor User’s Installation Guide

Creating your own graphic underlay

If you need a custom graphic underlay, it is recommended that you order it from 3M Touch Systems, especially if the underlay will need to withstand temperature and humidity extremes.

Important

For the TouchSurround graphic underlay to withstand the same temperature and humidity extremes that the ET 350 monitor can withstand, you should not attempt to create your own underlay. Instead, order your underlay from 3M Touch Systems.

The monitor is designed to operate in temperatures from 32°F to 122°F (0°C to 50°C), and with humidity up to 95% (non-condensing). If you do not need this level of durability, you may choose to print the underlay yourself. There are two possible methods:

￿Silk screen printing onto a clear, soft, matte finish polycarbonate sheet. 3M Touch Systems recommends that you use a sheet that is 0.015 inches thick and printed on the “back” side (to prevent the printed surface from touching the glass).

￿Inkjet or color laser printing onto paper or a plastic sheet. Avoid having the printed surface in direct contact with the touch screen— under certain conditions it could adhere to the glass. Laminate the underlay with clear matte-finish plastic to prevent contact between the printed surface and the glass.

With either method, make sure the surface in contact with the glass has a matte finish to prevent the optical distortion known as Newton’s Rings.

After installing a new underlay, you will need to define new positions, actions and functions for your buttons or icons. For instructions on doing this, refer to the appropriate software guide (see “Software guides” on page 2).
