Offset

OFFSET -material is available in white and clear. Both materials are printable in UV-Offset with UV-Offset inks. Additionally the white material can be printed in traditional offset with oxidative inks.

Product properties

STAFIX®GRIP is a glue-free sticker material that adheres to various clean and very smooth surfaces with a silicon adhesion layer.
The material is removable without leaving any residue and reusable even up to 12 months. The material adheres on the unprinted side only.

STAFIX®GRIP OFFSET is available in white and clear and comes in sheets. The STAFIX®GRIP OFFSET film is printable with UV-curable and Oxidative inks only. The film does not have a receptive primer and therefore it does not absorb any liquid.

SHELF LIFE
In the sealed original package, unprinted material can be stored:

  • STAFIX®GRIP OFFSET White Polypropylene 18 months
  • STAFIX®GRIP OFFSET Clear PET 24 months

Storage

Store the unwrapped STAFIX®GRIP in the original package at 25% to 50% relative humidity and 15°C to 25°C temperature. The material should remain sealed in the original wrap until the STAFIX®GRIP material has warmed up to print-room temperature.
Print-room recommended relative humidity is 50% to 60% and temperature is 18°C to 30°C. After use re-seal the remaining unused material in the original package. Proper acclimatization allows for better feeding through the press.

STORAGE CONDITIONS PRINTING CONDITIONS
Humidity 25% to 50% 40% to 60%
Temperature 15° to 25 °C 18º to 30º

The warming-up time depends on the pallet weight and the temperature difference between the warehouse and the print-room, see table below for more details:

WEIGHT TEMPERATURE DIFFERENCE (°C)
FORMAT KG (APPROX) 10° 15° 20° 25° 30° 35° 40° HOURS

Once the STAFIX®GRIP OFFSET sheets have reached the same temperature as the print room you can open the boxes. Let the material acclimatize with the open box for 2 hours prior to printing for better runnability and efficient feeding. After use, repack the remaining unused material in the original package.

For pictures a raster of 60 – 70 l/cm is recommended. Create the black text of only 100% black for better registration. Avoid heavy deposits of ink for faster drying.

CLEAR MATERIAL
When printing an artwork on the clear material that will be used for window advertising, print the image mirror-wise and apply an additional covering white layer (either printed or a laminated layer) to reduce the transparency.
The sticker or poster is always installed from the unprinted side to the glass. The material adheres only from the unprinted side.

Always run a test with the right inks and right conditions before printing a commercial job, specially for the first time printing on STAFIX®GRIP.

The STAFIX®GRIP OFFSET film is printable with UV curable and oxidative inks specially designed for printing on plastic substrates. The film does not have a receptive primer and therefore it does not absorb any liquid.

ON PRESS
Print with low levels of water. STAFIX®GRIP absorbs no water and therefore very little water is needed (roughly less than half of what would be required with paper). If possible use metal plates that carry minimal water. The plate requires only enough water to keep the surface wet. For oxidative inks keep the alcohol level from 10 to 15% and follow the guidelines from the ink supplier. The acidity of the dampening solution should not be set too high, (PH value approx. 5.5). Do not apply too high print impression pressure in order to avoid stretching of the film.

INK USAGE
Print with low levels of ink density for faster drying and to avoid offsetting.


Drying

TRADITIONAL OFFSET
Do not use IR dryers; the intensity of the IR lamps may cause the film to deform due to excessive heat. This will affect the registration. Additionally it may also extend the drying time. Use a larger grain powder about 40 – 50 microns to facilitate drying. Larger grain powder allows more air to pass between the sheets and therefore means faster drying.

Dry the sheets in stacks of 200-250 sheets. Offsetting can occur if stacks are too large or the powder grain size is too small. Too large stacks may also obstruct airflow slowing down significantly drying time. Plan for 24 – 48 hours of drying time. Make sure the drying room has proper ventilation; this will speed up the drying process.

UV-OFFSET
Adjust the UV-lamps to a level that still cures the inks but does not deform the film. When using a hybrid-printing machine turn off the IR lamps.

COATINGS
Varnish or coatings can be applied, Make sure you use previously tested varnishes and coatings.


Post-press

STAFIX®GRIP OFFSET can be die-cut and kiss-cut. Always round the corners when die-cutting or kiss cutting because the inner-sharp corners might cause the film to tear, Perforating, binding and direct mail inserting is also possible. When trimming, use sharp, nick-free blades.

PACKING & SHIPPING
Protect the products well from dust when sending the finished goods to your client. Pack the material flat and do not fold the sheets.
