Bromoil transfer prints were produced by using a bromoil print as a printing plate. The process, similar to lithographic printing, allowed ink to be transferred from the surface of the bromoil print to a piece of paper producing and image consisting of ink on paper. The bromoil print could be re-inked several times to produce multiple copies of an image. Unlike bromoil prints, bromoil transfer prints do not have an emulsion layer. (See Bromoil Transfer) 

Introduced in 1904, Oil process was a predecessor to the Bromoil process. Paper coated with gelatin was treated dichromate salts and then contact printed under a negative. The following steps were nearly identical to the bromoil process. Papers for the oil process could be hand made, but were also commercially available. Differentiating between oil and bromoil prints can be difficult. Oil prints tend to be small than bromoil and the paper fibers are more prominent due to the lack of a baryta layer. 

Like the bromoil transfer, oil transfer were produced by using the oil print as a printing plate transferring the ink image to a paper substrate.
