General handling and transport

Standard Re-board® pallets and sheets are typically from 2.2 m to 3.2 m long (86.6” to 126”) and have the width of either 1.22 m or 1.6 m (48” or 63”).

When transporting Re-board® pallets it’s recommended to use truck forks with a length of at least 2.2 m (86.6”) to avoid damages.

Considering the weight and size of the Re-board® boxes, moving and handling them requires extra caution and attention. Always lift Re-board® boxes at both ends, whilst the opening should always be carried out carefully with the box lying on a flat surface.

After unpacking a pallet, it is of great importance to remove and save each pallet label. The pallet label contains the pallet identification number, which is a prerequisite all tracking and troubleshooting in connection to flaws and imperfections.

Storage and stacking

Re-board sheets have no general “shelf life” and if stored correctly, the sheets can be stored for a long period of time before use.

Temperature and humidity has a big effect on the form stability of Re-board® sheets, hence it is essential that the sheets are stored flat in a controlled indoor environment, avoiding direct sunlight as well as rain.

Optimal storage conditions for Re-board® sheets are relative humidity levels of 50-55 % (RH) and a temperature of 18-23 ºC (64-73 ºF). If there is a risk for large temperature differences remove the protective plastic from the pallet, otherwise condensation may occur.

Pallets of the same size (length and width) can be stacked and stored two and two on top of each other. Never stack pallets with different length and width on top of each other as this can cause damages such as sheet warping. Always use a protection sheet between pallets and make sure that the pallet feet are in line.

Sheet handling

It is crucial to use clean cotton gloves when handling the sheets, both before and after printing. This to eliminate the risk of fingerprints and other contamination's affecting the printing area, or post print ink smudging.

The use of gloves also protects your hands from paper cuts as sheet edges and corners can be rather sharp.
Always lift the sheets at both ends when handling or stacking to avoid scratches and scuffs on the surface.

To ensure a high quality and consistent print, gently brush off any fibre residues and dust from the sheets before printing. Also avoid touching the sheet surface immediately after printing as the printed area needs time to dry.

Acclimatization

Re-board® sheets contain wood fibres which are hydrostatic. Hence rapid changes in temperature or humidity levels may affect the flatness of the sheet and cause bending and warping.

To avoid sheet warping, make sure that to acclimatize sheets before use. It is recommended to let the Re-board® sheets rest for one (1) day before converting, and more specifically letting the sheets acclimatize one (1) hour per one degree of Celsius in temperature difference (1 °C or 1.8 °F).

Example: If sheets are brought from a 0°C storage area into a 25°C printing area, the sheets need to acclimatize for 25 hours before usage.

Tolerances

Format accuracy and form stability within tolerances is one of Re-board’s great advantages. However, temperature and humidity may affect the flatness of the sheets, hence it is essential to store sheets according to instructions and always ensure acclimatization before use. If sheet specifications are to be found outside stated tolerances, make sure to save the pallet identification number (Pallet ID) for tracking purposes. - Sheet width tolerance: +/- 3 mm - Sheet length tolerance: +/- 3 mm - Sheet thickness tolerance: +/- 0,3 mm - Sheet curvature/warping tolerance from flat in acclimatized conditions: max 10 mm at sheet corner
