In a diffusion-transfer processor for use with successive pairs of donors and receivers, back-side wetting of the receivers is prevented by (a) passing the meniscus of activator, which collects at the entry nip of the lamination rollers, through a gap between the rollers after exit of each pair from the rollers, and (b) removing the activator passed through the gap from the roller that contacts the back sides of the receivers to dry that roller before contacting the back side of the next receiver.
