Product properties

STAFIX®STATIC is a glue-free sticker material that adheres to almost any clean surface with a static charge. The material adheres on average for 3 months and is easy to apply and removable without leaving any residue. The material adheres on the unprinted side only. STAFIX®STATIC INDIGO is available in white and clear and comes in sheets. The material consists of two layers:

• 50 microns thick, polypropylene film. (Top layer)
• 200 g/m2 paper backer. (Bottom layer)

The film is fully attached to the paper backer by a low-tack glue. STAFIX®STATIC INDIGO is designed for printing in sheet-fed HP Indigo® presses, the film has a special receptive coating for HP Indigo®s’ ElektroInks™, the coating allows excellent ink transferability and ink adhesion. STAFIX®STATIC film is 100% recyclable as a grade 5 plastic and doesn’t release toxic gases into the environment if incinerated. The cardboard used for the backer is PEFC & FSC certified. SHELF LIFE In the sealed original package, unprinted STAFIX®STATIC sheets can be stored up to 12 months following our storage guidelines.

Packaging and formats

FORMAT TOLERANCE Sheets: Size tolerance is 0 / +5mm in machine and cross direction Sheet flatness tolerance is 8mm Rolls: 0,5% in length CUSTOM SIZE ORDERS For larger quantities, cost efficiency can be achieved by producing tailored size sheets. Please consult us regarding minimum quantities and delivery times.

Storage

Store the unwrapped STAFIX®STATIC INDIGO in the original package at 25% to 50% relative humidity and 20°C to 27°C temperature. The material should remain sealed in the original wrap until the STAFIX®STATIC material has warmed up to print-room temperature. The print-room recommended relative humidity is 50% to 60% and the temperature is 20°C to 27°C. 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:

Once the STAFIX®STATIC material have reached the same temperature as the print room you can unwrap the pallet. Let the material acclimatize without the wrap / plastic bag for 2 hours prior to printing. STAFIX®STATIC INDIGO sheets are packed in a plastic bag within the box. After use re-seal the remaining unused material in the original package. Sudden changes of temperature and/or humidity may cause the cardboard to change size, and this could wrinkle the film.

This segment is intended to help the designers and the prepress department as well as machine operators to improve the printability and performance of the STAFIX®STATIC products.

Do not use a Total Ink Coverage (TIC) greater than 240%. Use the Under Colour Removal (UCR) and Grey Component Replacement (GCR) if needed. Heavy deposits of ink should be avoided, especially near the edges of the artwork, to prevent the film from curling or rippling. Leave an unprinted border at the edges of the artwork if possible. Do not overlap a combination of two or more solid colours. Heavy layers of ink may cause the film to swell.
For pictures a raster of 60 – 70 l/cm is recommended. Create the black text of only 100% black for better registration.

Please see the table below for the maximum printable area by product:

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 to reduce the transparency. Rasterize the covering white to 95%. Additionally to the covering white you can use 240% maximum TIC on the colour build.
The sticker or poster is always installed from the unprinted side to the glass. The material adheres only from the unprinted side.
Not all the presses have white inks available; consult with your printing house beforehand.

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

On press

Fan the sheets properly prior to loading Place the sheets in the drawer for thicker substrates
For the 3000’s and 5000’s series set the blanket temperature to 145° -150°C.
The best registration is achieved by using “one shot mode” when printing.
When using “one shot mode” the blanket temperature can be set at 160° to 165°C

If you do not have “one shot mode” available, in order to improve printing registration run the material using a null cycle before printing.

STATIC ELIMINATORS
Do not use any antistatic devices including sprays, tinsel, or on-press electronics. These will reduce the static charge loaded in the material.

COATINGS
Do not use any varnish or aqueous coatings! Coatings will eliminate the static charge and curl the material.

Post-press

STAFIX®STATIC can be die-cut and kiss-cut. Avoid long thin shapes as they might curl away from the surface and round the inner corners because the inner-sharp corners might cause the film to tear, always round the corners when die-cutting or kiss cutting. Perforating, binding and direct mail inserting is also possible. When trimming, use sharp, nick-free blades.

PACKING & SHIPPING
Protect the products well from humidity and dust when sending the finished goods to your client. Avoid packing the material with products that emit VOC’s (Volatile Organic Compounds / Solvents) as they will reduce the static charge. Do not pack the material using vacuum-sealed packaging; the freshly printed ink can also emit VOC’s. Ship the materials flat.
