8. Kuyika kwa machubu ndi zingwe

Ichi ndi chitsanzo cha kugwiritsa ntchito kutambasula filimu m'munda wapadera.Zida zonyamula katundu zimayikidwa kumapeto kwa mzere wopanga.Kanema wotambasulira wodziwikiratu sangangolowetsa tepiyo kuti amange zinthuzo, komanso achite ntchito yoteteza.Makulidwe oyenera ndi 15-30μm.

9. Kutambasula mawonekedwe a pallet limagwirira ma CD
