This study was to get the optimum conditions on bleaching by mixing of various colored ledgers with white ledger by 50：50 ratio. This bleaching was carried out by two steps, reductive-oxidative process was shown a better brightness compared to oxidative-reductive one. Especially, in reductive bleaching using sodium hydrosulfite, the aging temperature should keep above 6$0^{circ}C$ irrespective of aging time, alkaline condition was more effective than acid one. Final brightness after bleaching and feinting was obtained over 78% to be used by the raw pulp of tissue.
