Need external tray dimensions for paterson 20x24 trays

[wildbill]

I need to know how much space these take up. If someone could measure one for me. I'm building a new sink and I know from experience that paterson trays are larger than many because of the spout.
Thanks

wildbill,

I asked the same question a while back. If you look for posts by "semi-ambivalent" you'll find the thread. I believe 20x24 was mentioned in it. If not I bet you could get you answer with an email to the great folks at Freestyle.

s-a

No answer on that thread. I'd rather get my answer here, no one can read a ruler like an apuger

External dimensions are:

25" (side-to-side to spout) x 29 1/4" (front-to-back to spout) x 4 3/8"

Excellent, I was going to build the sink 30" deep anyways. I doubt I'll print 20x24 in trays (probably use jobo) anyway but need to prepare for the unexpected. I could always put a mattress in the sink if my wife gets mad at me as well.

If you process FB prints in a Jobo tank you’ll likely spoil it.

Jobo drums are made to just accept color prints that are fully encapsulated in a waterproof resin. Since they are waterproof, RC prints don’t expand because the paper doesn’t get wet.

A Jobo 3063 20” x 24” print drum will hold the print with the opposite ends just about touching. As an FB print gets soaked with the water component of processing solutions, it increases size significantly. The paper is constrained end-to-end and by the periphery of the drum. The expanded print will buckle like the corrugated layer of a corrugated cardboard shipping box.

In some cases, the emulsion will be sharply and permanently creased by this buckling. The print can be flattened later, but any sharp creases that form are permanent. B&W RC prints can be processed in a Jobo drum, but FB is best done in trays or a trough.

Now that's interesting. Do you know how much the print expands?
My first thought is to have a 1/4 inch border and pre soak the print and them make sure it overlaps in the tank.

Each paper would expand and shrink different amounts. Most expansion is across the grain. I remember using a thin Kodak paper which out of the box was 42" wide. When wet it was over 43" wide.
