- Paper storage
To ensure good production conditions. MGI recommend you to store your paper prior to production
following the above conditions:

The paper to be spot coated should be stored flat to avoid any deformation and curling. They
should stay also with their original packaging until the last moment prior to printing.

The paper should be stored within a room where the temperature never deviates from 20-25°C
(68°-77°F). The relative humidity (RH) should be kept in the range of 35-55% without
condensation. Do not hesitate to use to use air humidification system when the quality of the air
is to dry. If humidity in the paper storeroom or print shop is too low. the material releases
moisture into the room. This leads to unwanted changes in the dimensions of the paper. The
paper then is no longer perfectly flat and cannot be processed efficiently. Doubling. register
differences. wrinkling and distortion are difficulties frequently encountered as a result of low
humidity. If paper is too dry during processing at low humidity. electrostatic charges are created.
The paper sticks together and stops running smoothly through the printing press. This also
applies even more dramatically to synthetic materials such as PVC or polypropylene.

An air conditioning system is also a good solution to keep the air dry when there is too much
humidity (RH). Do not hesitate to ask your paper supplier about the best storage conditions for
its substrates.

Acclimation before production
Before production. the paper should reach the production room to be acclimated. The paper should stay
24-36 hours in the production room prior to production, but keep it away from the heater or a cold wall.
Same parameters apply when printing (ambient air 20-25°C and RH 35-55%).
3.4.7 Precautions when handling varnish
The JETVARNISH 3DS varnish is a skin irritant. Any manipulation in its liquid form needs to be done using
gloves (one box of gloves is provided with the machine), protective clothes (such as a lab coat) and
glasses. During fill up and cleaning. it is recommended to have the use of a table, a trash can and paper
towels. MGI also provides a cleaning solution. After drying. the varnish can be handled with no issue.
3.4.8 Precautions with the UV rays
The JETVARNISH 3DS emits UV rays during production. Those rays are contained within the equipment
by the protective covers, and thus do not present a risk to the operators. However. during maintenance
and adjustment operations. it is imperative that UV filtering glasses be worn. You can order them from
MGI. reference PN 4004.
