GEDAKOP is a simple system for producing your own single or multi-coloured anodised aluminium panels. The dye is added to the anodised layer of the aluminium and the finished panel sealed in hot water. This 'subsurface' imaging produces permanent scratch and solvent resistant aluminium panels. The GEDAKOP aluminium is available from stock in sizes up to 500 x 1000mm and thickness' from 0.2 to 3.00mm. It is ideal for 'one offs' or short production runs.
Standard GEDAKOP has a matt aluminium finish. 'Polished' finish material available on a non-stock basis for approximately 20% extra.
“All sizes are nominal only. Due to the limitations of the anodising process it may not be possible to apply dye right to the edge of the panel. Please allow a 15mm border for waste.”
Nine simple steps - All that's needed to produce an anodised aluminium panel!

| 1. Produce an Artwork Design the panel using dry transfers or CAD outputting to a pen plotter or laser. Any opaque image on a transparent or translucent carrier will suffice. Our LaserStar film produces superb artworks. |
|
|
|
2. Cut material Select a piece of GEDAKOP and cut to size using one of Mega's shears. |
| 3. Expose to U.V. Place the positive artwork on top of the GEDAKOP panel and expose in a UV unit. For optimum results use a Mega AY vacuum UV unit. |
|
|
|
4. Develop the image Develop the exposed image by placing the panel under running water. Blot the panel with newspaper and dry with a hot air blower or hair dryer. |
| 5. Dye the panel Apply the appropriate colour dye or dyes to the panel. Remove excess dye and dry with a hot air blower or hair dryer. |
|
|
|
6. Strip the Photoresist Remove the Photoresist from the panel using the stripper. |
| 7. Seal the panel Place the stripped panel in a Mega Sealing Tank for 45 minutes minimum. This will offer excellent protection sealing the dye within the anodic layer itself. |
|
|
|
8. Punch the panel Add any required holes using a press. |
| 9. Finish Trim to final size using a Mega Shear and apply radius corners with a Corner Rounder. |

Stainless Steel Sealing Tanks
HB320 – max panel size 400mm x 500mm
HB1000 – max panel size 510mm x 1000mm
A completed Gedakop or ANO Transfer panel should be immersed in 98°C water for at least 45 minutes to seal the dye molecules in the surface of the aluminium, thus protecting the panel from scratching or by chemical attack from solvents etc. To carry out this process two Sealing Tanks are available. These tanks consist of a stainless steel inner tank and hinged bright stainless steel lid both of which are supported on a powder coated black steel frame.
The inner tank has 20mm thick high temperature thermal cladding between it and the supporting frame. The outside cladding is white polypropylene sheet attached to the outside of the supporting frame.
The front control panel houses an illuminated rocker switch and a digital temperature controller which is set to 98°C +/- 1°C. This temperature can be changed by the user if necessary.
The tank is also fitted with a low level cut out device to prevent it from being run if the liquid level falls below the top of the heater. A drain tap fitted to the bottom of the tank to enable it to be easily emptied.
Each tank is supplied with 5 basket holders.

Sealing Consumables
Gedaseal solution needs to be added to the water used in the sealing
tank. It helps seal the panels and prevents excessive ingress of dye into the
sealing water. 'Seno' universal solvent is needed to remove the protective seal
and clean the fin-ished sealed panel. The solvent can also be used to thin the
Gedalu screen printing pastes.
