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.
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).
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.
