White rectangular developing tray with ribbed base and pouring lip

Paterson Photographic

Paterson Photographic 16x20" 3" Deep White Print Developing Tray 327

SKU CH-G2JW-ZKGW0

A deep 16 by 20 inch developing tray made from chemical-resistant polypropylene with a patented thermometer holder and large pouring lip for drip-free emptying

  • Large 16x20 inch format handles big prints
  • 3 inch depth holds ample chemistry volume
  • Thick polypropylene resists photographic chemicals
  • Patented base ribbing prevents thermometer sliding
  • Extra large pouring lip minimises chemical splash

Large-format developing tray

The Paterson Photographic 16x20 inch tray is a moulded polypropylene vessel designed for wet darkroom processing. Its three-inch depth holds enough chemistry for full-sized prints while the ribbed base prevents sheets from adhering during agitation. A patented thermometer holder keeps the probe upright and out of the emulsion side.

Darkroom printers needing chemical resistance

Photographers who process fibre or resin-coated paper up to 16 by 20 inches will value the rigid construction and splash-reducing pour lip. Workers who require heated circulation systems or automated roller transport should look at purpose-built machinery instead.

Fits standard bench workflow

The tray sits flat on any level surface and nests with identical units for compact storage. Its generous pour lip allows drip-free transfer back to storage bottles, reducing waste and keeping the work area dry between sessions.

Questions about this item

What sink or bench space do I need to accommodate the 16x20" footprint?

Allow at least 16 by 20 inches of flat, chemical-resistant surface; the tray sits directly on the bench and the extra-large pouring lip extends slightly beyond the moulded edge.

Can I use my existing Paterson thermometer with the patented holder on this tray?

Yes — the moulded thermometer holder is designed to keep any standard darkroom thermometer from sliding into the solution during development.

How do I confirm the base ribbing is preventing prints from sticking after the first batch?

Process a test sheet; if the print lifts cleanly without residue and the ribs show no chemical etching, the anti-stick design is working as intended.
