Hints and Tips

Leave newly wrapped vehicles indoors overnight

Once you have finished your vehicle wrap, ideally it’s best to keep the vehicle indoors in a controlled temperature environment overnight. This gives the adhesive time to bond. Moving a vehicle from 20 degrees to -4 degrees will be a massive shock to the vinyl and adhesive, which could lead to shrinking. Ensuring the wrap is post heated correctly and kept in overnight avoids any potential issues.

How to store digital print wrap films

Vinyl needs to acclimatise, ideally for 3 hours at room temperature 20-23 degrees before printing to allow optimum print quality. Dry warm conditions are a must for vinyl storage. Damp areas can create problems with paper liners, that can absorb moisture and cause cockling and print head strikes whilst printing.

Use plenty of excess to avoid overstretching

When wrapping to the edge of panels, allow an excess of 150mm either end/side (300mm in total) to cope with the stretching needed to get rid of wrinkles and creases over a larger surface area. By avoiding overstretching the film, the vinyl is under less stress and will not shrink back from the edges. This technique is also useful when applying matt films to avoid glossing, usually caused by overstretching.

Post-heating is critical in any areas that have been stretched

Heat inch by inch, always removing the heat gun before reading the temperature of the vinyl. Use an infrared digital thermometer to ensure the film is post-heated to the correct temperature. 3M recommend post-heating IJ380 Series to over 80ºC for single layers and 120ºC on overlapped areas, whilst using the application roller in recesses to achieve maximum bond. For 3M IJ180Cv3 post-heating should reach 100ºC.

More tips on outgassing

The ideal temperature for outgassing would be 23 degrees. If loosely winding the roll, it is important to circulate air, using a fan to blow away from the graphic. It is still difficult for solvent to escape from the centre of the roll where it will be still relatively tight together. If possible, we would recommend sheeting your graphics and lay them out flat on a bench with constant air flow for 72 hours at 23 degrees. If you’re printing excessively dark areas, it’s advisable to leave latex printed graphics longer before laminating.
