Thread: Dark Streaks on RA4

    Re: Dark Streaks on RA4

    Thanks for the recommendations on chemicals.

    @duolab123 I did level out the unit when I set it up initially. My problem is forgetting to adjust the support rollers to the correct orientation when switching between drums of different diameters. I blow one sheet about every time I switch from film to print processing. Luckily I haven’t made the same mistake on film.

    I finally got to do some printing today, and used the stop+ rinse. 3 prints in and no streaks!

    The acetic acid can change the pH of the blix, especially if you reuse the blix. The water rinse helps reduce that effect.
