wet gate printingの例文

• Wet gate printing eliminates the refraction itself by filling in the gouges in the substrate with a fluid such as perchloroethene that shares approximately the same refractive index as the substrate.
• It is therefore still diffuse when it exits, ensuring an image of the scratch will not show up as strongly on the new print . ( Only the desired image on the surface of the emulsion ends up being captured in focus . ) However, it cannot remove deep scratches, and is thus less effective than wet gate printing.
