Millimetric grid, silkscreen printed in blue on 200µm (0,2mm) polyester clear film.
The thickness gives a very good strength.
Indication of centimeters, 5mm & millimeters.
Made for registering marks on etching press bed and for mounting films on light table.
We recommend to place printed side face down on the bed and to use permanent marker to draw marks (washable with alcohol) on the non printed side.
Take care to bevel lightly the edges of the back of the plate not to cut the polyester by pressure. It is possible to place a second film that will avoid scratches.
