Sludge is considered by many to be a factor limiting the usefulness of monobaths. A particular film-monobath combination was tested for the effects of sludge on sensitometry, granularity, and acutance. It was found that the presence of sludge did not alter the sensitometric characteristics; however, through solution usage, the acutance and granularity decreased. Removal of the the sludge by filtration during usage resulted in improved image quality over the comparison solution in which sludge was allowed to accumulate.
