uniform porosity in the oxide layer, i.e., oxide film, to avoid dirt contamination. Good aluminum oxide immediately print the best, if not immediately printed, soft paper application septum wrapped or dried directly on the shelves, storage time should not exceed one week. The surface of the aluminum oxide layer can absorb dye, water and other salts, it is not something with greasy hands or contact surface when printing. When the ink is printed onto the oxide layer, namely the ink penetrate pores. Heating the next step is to accelerate the ink to penetrate pores until all the pores in the surface of the ink-covered been filled so far.

6, closed: its role is firmly sealed in the ink within the pores, and never rise overflow or diffusion. No ink coverage to complement the site is closed to fill the role of the oxide film is also the gap, making it impervious to enhance corrosion resistance surface. Generally use nickel sulfate solution for blocking. Recipe: Chinese NICKEL 10-12 ml, temperature 80-90 degrees, 10-15 minutes.
