Proses finishing artikel croste omega mempunyai kendala, yaitu pada saat di uji color fastness to rubbing kulit mengalami kelunturan pada felt wet 250 cycle, karena pada artikel kulit ini kondisinya lembab melebihi standar pabrik. Maka dilakukan trial membuat sampel dengan humidity kulit antara 8-30 % dan menguji kadar airnya untuk masing – masing humidity kulit agar mengetahui pengaruh humidity kulit terhadap uji color fastness to rubbing. Berdasarkan sampel yang dibuat dengan humidity kulit antara 8-30%, untuk humidity kulit 20 % dan 30 %.
