Copper Plate Preparation

• Match your image size to the size of your plate.
• It is preferable to cut the plate to size before adhering the ImagOn film. 
• The plate can be trimmed with the developed ImagOn on the plate but there is a tendency for this trimmed edge to be more jagged than the other edges of the plate. This fact will become more obvious in the finished print. 
• Round edges of plate with a file 

No need to bevel plate if use roofing copper (22 gauge)

Particle Dust Mask REQUIRED

Dry sand only in a well-ventilated space.  It is advisable to use the wet sanding method which prevents sanding dust from becoming airborne.

• Degrease plate with electric palm sander 320 grit sandpaper (wet or dry). 
• Keep bucket of water at sanding station and use the paper wet to reduce dust. Sand plate until the copper has an even sheen.  It is not necessary to remove all of the sanding marks.
• If you want less plate tone, use 600 grit sandpaper after the first sanding with 320 grit.
• Sand edges to make sure the edges cannot cut you or the press blankets.
• Wipe off the dust with a clean rag.
• Do not get fingerprints on the plate

The metal (preferably roofing copper) plate
Sand immediately before laminating the ImagOn
