3. A jig might be required according to the shape of the print object (media).
The distance between the print head surface and the print object (media) surface becomes longer upon print
according to the shape of the print object (media). If the distance becomes longer, ink mist is likely to occur,
and the UV lamp light is also likely to be reected. To prevent ink mist and reection of the UV lamp light, you
need to level the surface of the print object (media) as much as possible using a jig. Some examples in which
a jig is required are explained below:
* If the surface of a jig is likely to be reected, it has an adverse eect. Coat the surface of a jig with “matte
black” such as acrylic lacquer.
When a print object (media) has a 2 mm or more difference in the height
If the surface of a print object (media) is uneven and/or curved, and the height dierence is 2 mm or more, a
jig needs to be used.
Example
Even if the actual print area is at, if the print object (media) has a 2mm or more unevenness, a jig needs to be
used. Cover the 2 mm or lower area than the actual print surface with a jig so that the height dierence will be
less than 2 mm. There is no need to use a jig for the areas where the height dierence is less than 2 mm.
Example
When you make a print on a curved surface, you need to use a jig to reduce the height dierence of the print
object (media) to less than 2 mm.
* There are conditions in the height settings when the print object (media) surface has a height dierence.
For more information, refer to
P. 39, "Height Settings When the Print Surface is Uneven".
