Storage Instructions
All Grafiprint materials always need to be stored in their original packing and with the original protection flanges (and preferably stored
vertically).
In order to avoid any loss of quality, the Grafiprint Inkjet Vinyl should also be stored in suitable conditions, that is at a temperature
between 10 and 20°C, and a relative humidity of 50 %. Under these conditions, the vinyl will have a shelf life of 18 months.
Before printing on the Grafiprint materials, we advise you to have them acclimatize for a certain period of time (at least 12 hours) in the
room in which they will be printed.
Laminating
A laminate can prolong the outdoor life of a digital print considerably. This also goes for the prints that have been made on the
Grafiprint MP20 micro‐porous vinyl. As this material does not hold any inkjet coating, it is not necessary to apply the laminate with an
overlap, or to overlaminate the sides. It is sufficient to apply a laminate up to the side of the print. Before applying a laminate on the
Grafiprint MP20, please make sure the inks have dried sufficiently (3 days up to 1 week), as remaining solvents and moisture can lead to
blistering and the laminate coming off.
Removal
MP20 is non‐PVC and will break when you try to remove it after ageing. To avoid problems when removing it, we advise you use the
following work method :
1. Remove the laminate.
2. Moisten the MP20 with a cloth, moistened with isopropanol. Let this absorb for a while.
3. Scrape off the MP20 with a Grafitack squeegee. The material will crumble off completely.
4. Remove the remaining glue with isopropanol.
Important
The information, mentioned in this product data sheet, is based upon tests that were executed by Grafityp, and that we consider to be reliable. The information always
represents an average, a minimum or a maximum value, and should be considered as such. It is only given for your information, and does not give any guarantee. It is up
to the end user to decide whether or not the product is suited for his particular application.
The outdoor life span refers to outdoor use under Central European conditions. The life span of our films is based upon professional application on a dry, degreased and
suitable background. Tropical conditions, or the use near chemical emission, may have a detrimental effect on the life span.
1) The thickness of the Grafiprint materials may vary slightly. The indicated value is an average value, obtained from a series of measurements, in which a tolerance of 10
% is acceptable.
2) The dimensional stability is the shrinkage in %. This value is measured by applying the film on aluminium, and placing it in a hot‐air oven at 70°C for 48 hours. The
indicated value is a maximum value, obtained from a series of measurements.
3) The adhesion strength is measured on glass, and this after 20 minutes and after 24 hours. The film is removed again in an angle of 180° and at a speed of 300 mm/sec.
The indicated value is an average value, obtained from a series of measurements.
