I forgot I had these 5x7 hard rubber trays, Ace brand, inherited when a friend gave me a box of photo stuff.
As I am about to print, small at first, any reason not to use them?
They have recessed grooves, instead of raised ridges, and seem to need at least 350 ml of solution.
I do like the vintage feel...
I have 8x10 classic trays as well, may just be more comfortable, and better at washing?
I have a set of 5X7 trays, never use for prints, I on occasion use for 4X5, well not in years other than last step when using Photo Flow (?) before hanging to dry. I guess If was going to print 4X5 I would use them. When I print 5X7 I use 8X10 trays, 8X10 in 11X14, and 11X14 and larger I use paper drums.
