The process was later refined through the incorporation of dye imbibition, which allowed for the transferring of dyes from both color matrices into a single print, avoiding several problems that had become evident with the cemented prints and allowing multiple prints to be created from a single pair of matrices.

A receiver print, consisting of a 50 % density print of the black-and-white negative for the green record strip, and including the soundtrack, was struck and treated with dye mordants to aid in the imbibition process ( this " black " layer was discontinued in the early 1940s ).

That same year, the Technicolor lab adapted its dye transfer process to derive matrices and imbibition prints directly from Eastmancolor negatives, as well as other stocks such as Ansco and DuPont color stocks . " Jeff Chandler, was the last American-made feature photographed with a Technicolor three-strip camera.

Essentially, the " Imbibition Agreement " lifted a portion of the " Monopack Agreement's " restrictions on Technicolor ( which prevented it from making motion picture products less than 35mm wide ) and somewhat related restrictions on Eastman Kodak ( which prevented it from experimenting and developing monopack products greater than 16mm wide ).

By the time when " Moonwalk One " was finished, light-sensitive emulsion film had become much better technically and was much cheaper than the Technicolor imbibition process . " Moonwalk One " was one of the last films created using that process, which was shut down forever shortly thereafter.

In 1928, the system was refined by the adoption of dye imbibition, which allowed for the transferring of dyes from both color matrices into a single one-sided print, thus eliminating the complication of attaching two prints back to back and allowing multiple prints to be created from a single pair of matrices.
47.
A receiver print, consisting of a 50 % density silver print of the black-and-white negative for the green component, and including the soundtrack and frame lines, was made and treated with dye mordants to aid in the imbibition process ( the inclusion of a " black " image was discontinued in the early 1940s ).
48.
Dye imbibition was not suitable for printing optical soundtracks, which required very high resolution, so when making prints for sound-on-film systems the " blank " film was a conventional black-and-white film stock on which the soundtrack, as well as frame lines, had been printed in the ordinary way prior to the dye transfer operation.

A late modification to the " Monopack Agreement ", the " Imbibition Agreement ", finally allowed Technicolor to economically manufacture 16mm dye-transfer prints as so-called " double-rank " 35 / 32mm prints ( two 16mm prints on a 35mm base that was originally perforated at the 16mm specification for both halves, and was later re-slit into two 16mm wide prints without the need for re-perforation ).

Among these are his investigation of the periodicity of growth in length, in connection with which he devised the self-registering auxanometer, by which he established the retarding influence of the highly refrangible rays of the spectrum on the rate of growth; his researches on heliotropism and geotropism, in which he introduced the clinostat; his work on the structure and the arrangement of cells in growing-points; the elaborate experimental evidence upon which he based his " imbibition-theory " of the transpiration-current; his exhaustive study of the assimilatory activity of the green leaf; and other papers of interest.
