TW 5560 Flat Iron Oxide Yellow — Water-Based Poster Ink
TW 5560 Flat Iron Oxide Yellow is an earthy, ochre-gold water-based poster ink from the TW 5500 Multi-Purpose Water-Based Series — a warm, muted yellow based on iron oxide pigment chemistry that delivers the natural, organic golden tones that synthetic yellows simply cannot replicate. Fine art serigraph studios, antique-aesthetic poster printers, and earth-palette design shops reach for TW 5560 when yellow needs to feel aged, natural, and hand-crafted. Press ready, formulated for the full TW 5500 substrate range.
Key Features
Authentic Iron Oxide Ochre Character
TW 5560 is built on iron oxide pigment chemistry — the same pigment family used in earth pigments throughout painting history. The result is a warm, slightly muted golden ochre that reads as natural, organic, and historic rather than synthetic and bright. This is the yellow that makes antique-aesthetic, botanical, and earth-palette printing feel authentic.
Earth Tone Color System Anchor
TW 5560 is the starting point for building the full range of earth tones within the TW 5500 system. Add TW 5525 Black for deep olive and khaki. Mix with TW 5516 Warm Red for burnt orange and terra cotta tones. Add TW 5521 White for warm cream and parchment tints. The iron oxide base keeps all mixes warm, natural, and cohesive.
Rich Flat Finish
TW 5500 Series inks cure to a controlled flat/matte surface that eliminates glare, enhances color depth under gallery and stage lighting, and gives printed pieces a premium hand-pulled serigraph feel.
Press Ready
Supplied press-ready for most applications. Stir well and print. Additives available for specific conditions but not required for standard runs.
Multi-Substrate Adhesion
Adheres to polystyrene, Tyvek®, Tedlar®, polycarbonate, treated polyesters, pressure-sensitive vinyl, and aircraft interior panels — the full flat-stock and specialty print substrate range.
Fast, Clean Cleanup
Water-based chemistry means screens clean with water. No harsh solvents, no hazardous waste from the ink itself. Faster between-run cleanup than solvent systems.
Color Character & On-Press Behavior
Understanding how TW 5560 Iron Oxide Yellow behaves on press — not just what it looks like in the bucket — is what separates professional poster printers from the rest.
Color Bias & Character
Warm iron oxide ochre — muted golden yellow. Natural, earthy character. Iron oxide pigment chemistry distinct from synthetic yellows in the TW 5500 lineup.
Mixing Potential
Foundation for earth-tone mixing. Add TW 5525 Black for deep olive and khaki. Mix with TW 5516 Warm Red for burnt orange and terra cotta. Add TW 5521 White for warm cream tints.
Halftone Performance
Clean halftone behavior. The earthy ochre character produces warm, natural-feeling tonal gradients in organic and nature-palette gradient work.
Print Sequence
Print early in earth-palette builds as the warm golden foundation. Works naturally with reds and darks in mid-sequence passes.
Who Prints with TW 5560 Iron Oxide Yellow?
🌟 Fine Art Serigraph Studios (Earth & Natural Palettes)
Studios producing botanical serigraphs, natural history editions, and antique-aesthetic limited prints rely on TW 5560 for the authentic ochre-gold character that synthetic yellows cannot replicate.
🎤 Concert & Poster Shops (Vintage & Antique Palettes)
Poster shops working in vintage, antique, and folk art aesthetic styles use TW 5560 as the yellow that gives prints the warm, aged quality of historic hand-printed posters. An earthy yellow foundation changes the entire feeling of a poster palette.
🍴 Heritage & Premium POP Display Printers
Heritage brands, craft spirits, artisan food, and premium retail displays that invoke natural or historic authenticity use TW 5560 for the genuine earthy yellow character that synthetic inks cannot fake.
🏛 Specialty Architectural & Environmental Graphic Printers
Environmental applications in heritage buildings, museums, and cultural institutions that require authentic earth-tone palettes for graphic interpretation signage and displays use TW 5560 for its natural pigment character.
On-Press Setup — TW 5560 Iron Oxide Yellow
Mesh Count
200–380 monofilament polyester. Start at 230 mesh for solid spot-color coverage. Use 305–380 for fine halftone and detail work. Higher mesh = finer detail, lower opacity per pass.
Squeegee
70–85 durometer polyurethane, sharp edge. Start at 75 durometer for most applications. Use a harder squeegee (80–85) for fine halftone work. Ensure sharp, clean edge for consistent ink transfer.
Stencil
Solvent and water-proof emulsion only. Murakami Photocure Pro dual-cure photopolymer is preferred for all TW 5500 Series work. For extended long runs, apply Murakami MS Hardener before going to press.
Drying
Air dry: 20–30 minutes at room temperature between color passes. Force dry: a few seconds at 90–150°F for faster production. Allow full dry before stacking prints or applying overprint passes.
Press Preparation
Stir TW 5560 Iron Oxide Yellow thoroughly from the bottom of the bucket before press-up. Off-contact distance of 1⁄16″–1⁄8″ is typical for flat-stock applications. Print a test sheet before committing to the full edition.
Cleanup
Clean screens with water immediately after press-down. Do not allow TW 5500 Series inks to dry in the screen. For stencil reclaim, use a standard water-based emulsion remover after water cleanup.
TW Graphics Additives for TW 5560 Iron Oxide Yellow
TW 5500 Series inks are press-ready for most applications. When press conditions require adjustment, TW Graphics offers a complete additive line specifically engineered for the 5500 Series system. Never use additives from other ink systems — they may cause adhesion, drying, or compatibility problems.

⚠ Over-Reduction Warning
Over-reduction with retarders and thinners can result in blocking and a significant reduction in drying speed. Never exceed recommended additive levels.
⚠ Test Before Production
Always run a test print on the production substrate first. Substrate surface energy, mesh count, and squeegee hardness all interact with final print results.
⚠ 24-Hour Evaluation
Allow at least 24 hours after printing before evaluating adhesion and suitability for the substrate and intended end use.

FREQUENTLY ASKED QUESTIONS
How does TW 5560 Iron Oxide Yellow differ from TW 5596 Saturn Yellow?
TW 5596 Saturn Yellow is a warm golden yellow formulated with conventional synthetic pigments for strong chroma and vivid golden character. TW 5560 Iron Oxide Yellow uses iron oxide pigment chemistry that produces a distinctly more muted, earthy, historical ochre character that reads as genuinely natural rather than brightly synthetic. TW 5596 is the vivid golden yellow; TW 5560 is the authentic earth-tone ochre.
What earth tones can I mix with TW 5560?
TW 5560 is the foundation for a rich earth-tone mixing palette within the TW 5500 system. Mix with TW 5525 Opaque Black for olive and khaki. Add small amounts of TW 5516 or TW 5514 for terra cotta and burnt orange. Mix with TW 5525 Maroon for warm dark brown tones. The iron oxide base ensures all mixes stay in a warm, earthy, natural-feeling range.
Does TW 5560 provide good long-term light-fastness for indoor applications?
Iron oxide pigments are among the most light-fast pigment families in the paint and ink world — they are more resistant to fading than most organic synthetic pigments. TW 5560 provides up to 3 years of indoor light-fastness consistent with the TW 5500 Series specification, and the iron oxide pigment base makes it particularly reliable for long-term display applications where color stability matters.
Is TW 5560 Iron Oxide Yellow press-ready or does it need to be modified before printing?
Press-ready for most applications — stir well from the bottom of the bucket and print. TW Graphics supplies the 5500 Series at correct press viscosity for standard equipment and conditions. You may need to adjust with a small amount of water or TW Z1820 Thinner if your press runs at higher speeds or your shop is warm.
Why is my ink drying in the screen between strokes?
Common in warm shop conditions or on slow edition runs. Fixes in order: (1) add TW Z1822 Retarder at 5% and re-test; (2) increase flood bar frequency to keep ink moving; (3) lower shop temperature or add airflow around the press; (4) switch to TW Z1823 Slow Retarder for extreme heat conditions. Never exceed 5–10% total retarder — over-retarding causes blocking.
I’m seeing pinholes in solid areas on the automatic press. What’s causing it?
Almost certainly foam from the flood bar beating air into the ink at high speeds. Fix: add TW 5100 Defoamer at 1% by weight, stir gently (vigorous stirring defeats the defoamer), and allow 2–3 minutes before going back to press. If pinholes persist, add another 0.5%. Never exceed 2% — over-defoaming causes fish-eye defects.
What substrates does TW 5560 adhere to?
The TW 5500 Series adheres to: fine art serigraph paper and board, polystyrene, Tyvek®, Tedlar®, polycarbonate, treated polyesters (substrate, not fabric), pressure-sensitive vinyl, aircraft interior panels, and skateboards. Always allow 24 hours after printing before evaluating adhesion to a new substrate. The end-user must determine suitability for the specific application before full production.
Can I mix TW 5560 with other TW 5500 colors?
Yes — all TW 5500 Series colors are formulated in the same ink system and mix cleanly together. See the “Mixing Potential” section above for specific color combinations that work well with TW 5560 Iron Oxide Yellow. For exact Pantone matching, TW Custom Pantone Water-Based Inks are also available.
What emulsion should I use with TW 5560?
We recommend Murakami Photocure Pro for TW Graphics water-based poster inks. Dual-cure photopolymer with 38% solids, outstanding resolution, and stencil durability for long poster runs. For extended high-volume runs, treat your Photocure Pro screens with Murakami MS Hardener before going to press for maximum stencil longevity.
