Gelatin vs Resin Coated Darkroom Paper: Which to Choose

Fibre-based and resin-coated papers behave very differently in the tray and on the wall. Compare drying, toning, texture and cost so you can pick the right black and white darkroom paper.
Quick answer
Choose resin coated (RC) paper when you want fast, predictable prints with short wash and dry times, especially for contact sheets, work prints and high-volume darkroom sessions. Choose fibre based (FB) gelatin paper when print quality, toning response and a paper-like surface matter more than speed. Many darkrooms keep both: RC for proofing and FB for final prints.
What the two papers actually are
Resin coated paper sandwiches the light-sensitive emulsion between the paper base and thin polyethylene layers on both sides. The plastic coating stops chemistry soaking into the paper, so wash times are short and the sheet dries almost flat. Fibre based paper, often called gelatin or baryta paper, uses a paper base coated with a gelatin emulsion and a baryta layer. It absorbs chemistry and water, which is why it needs longer washing and careful drying.
The practical difference is not just feel. RC paper sits flat in the easel and dries quickly, while FB paper can curl as it dries and may need weights or a blotter book. Both accept standard black and white chemistry, so the choice usually comes down to workflow, finish and the final look you want.
Handling in the tray and the darkroom
RC paper is the easier material for beginners and for anyone printing in quantity. It tolerates slightly rougher handling, drains quickly and does not need a long wash. That makes it a sensible choice for students learning to expose and develop, and for contact sheets where you are judging frames rather than finishing a print.
FB paper rewards slower, more deliberate work. Because the base absorbs water, development and wash times are longer and the sheet is more fragile when wet. The payoff is a surface that many printers prefer for exhibition work, and a base that responds well to selenium or sepia toning. If you plan to tone, test on a spare sheet first because FB and RC papers can shift colour differently.
Drying, flattening and finishing
RC paper air-dries quickly and usually stays flat enough to mount or store without extra work. FB paper needs a proper drying routine: blot, air-dry face up or between blotters, then press or weight the sheet if you want it truly flat. Rushing this stage is the most common cause of wavy FB prints.
If your darkroom has no drying space, RC is the pragmatic choice. If you have a press or a blotter book and time to use it, FB gives you a print that feels like a traditional photographic print rather than a plastic-coated sheet.
Cost, format and the paper you can actually buy
RC paper is generally cheaper per sheet and available in large packs, which suits proofing and teaching. FB paper costs more and often comes in smaller quantities, so it makes sense to reserve it for negatives you intend to print well. Format matters too: sheet sizes and pack counts vary by product, so check the listing rather than assuming a size is available.
One useful middle path is a variable contrast RC paper such as Ilford Multigrade, which lets you change contrast grade from a single box instead of buying several grades. That reduces waste when you are still deciding how a negative should look.
Trade-offs at a glance
- Speed vs surface: RC paper washes and dries fast and stays flat, but the plastic coating gives a different surface feel from a fibre base. FB gelatin paper needs longer wash and drying time but offers a traditional paper surface. Pick RC for volume, FB for the final look.
- Toning response: FB paper generally responds well to selenium and sepia toning because the base absorbs chemistry. RC paper can tone but the result is less predictable, so test a spare sheet first. If toning is central to your work, plan around FB.
- Cost per finished print: RC is cheaper per sheet and sold in larger packs, which suits proofing. FB costs more and often comes in smaller quantities, so reserve it for negatives you intend to print well. Budget for both if you proof on RC and finish on FB.
Products that show the trade-off
- Ilford Multigrade RC Deluxe Pearl 16 x 20in 10 Sheets: Ilford Multigrade RC Deluxe Pearl is a resin coated variable contrast paper: Multigrade is an Ilford trademark for black and white paper that gives five grades and half grades from a single sheet. You can fine-tune contrast without buying separate grade boxes, which is ideal for contact sheets and work prints where speed and cost control matter more than a fibre base.
- Firstcall Photo Heavyweight Satin (Olmec) A3+ 50 Sheets: Firstcall Photo Heavyweight Satin (Olmec) A3+ is a satin, ultra-white, smooth, water resistant resin-coated inkjet paper recommended for both dye and pigment inks, with a fade resistant micro porous coating. If your final output is digital rather than tray-developed, this gives you a flat, water resistant RC-style sheet in a large format for proofing or display prints.
- Permajet Museum Heritage 310gsm A4 25 Sheets: Permajet Museum Heritage 310gsm is a heavyweight fine art inkjet paper combining cotton and Alpha Cellulose fibres with a textured matt surface and natural mid-white base, suited to fine art work. It shows the fibre-based end of the market: a textured, paper-like surface for final prints where surface character matters more than speed or water resistance.
Which should you choose?
Best for
- Beginners and students learning exposure and development who want fast, forgiving prints
- High-volume darkroom sessions, contact sheets and work prints where speed matters
- Printers without drying space or a press who need flat sheets quickly
- Digital printers wanting a flat, water resistant satin sheet for large-format output
Not for
- Exhibition printers who want a traditional fibre surface and plan to tone
- Printers with a press, blotter book and time to manage longer wash and drying routines
- Anyone wanting a textured, paper-like fine art finish rather than a smooth plastic-coated sheet
