Epson 101 EcoTank Cyan Ink Bottle 70ml

Colour printing without compromise is no longer a luxury reserved for large organisations with substantial printing budgets. The Epson 101 EcoTank Cyan Ink Bottle delivers vibrant cyan colour for professional marketing materials, educational presentations, business documents with colour emphasis, and home colour printing — all at a cost per page so low that colour becomes routine rather than rationed. This 70-millilitre bottle of genuine Epson dye-based cyan ink yields up to 6,000 pages when combined with black, magenta, and yellow ink from the same 101 series. For Epson EcoTank L-series printers (L4150, L4160, L6160, L6170, L6176, L6190, L14150, and compatible models), the 101 cyan is the foundation of affordable, professional-quality colour printing. It combines brilliant cyan hue, fast-drying formulation, fade resistance, and the mess-free EcoFit refilling technology that defines the modern EcoTank printer experience.

Why The Epson 101 Cyan Is Essential For Professional Colour Printing

Cyan is the foundation of colour printing. It is the primary colour in sky, water, and ocean imagery. It is essential for vibrant greens when combined with yellow. It is the core of professional branding that demands brand-colour accuracy in marketing materials, business presentations, and company documents. The Epson 101 cyan delivers the brilliant, true-to-life cyan that makes these applications professional-grade rather than amateur-looking.

The EcoTank system fundamentally reimagines colour printing economics. Traditional colour cartridge systems cost pounds sterling per colour cartridge, rapidly accumulating to substantial expense for any office printing more than a few colour pages weekly. The 101 cyan yields 6,000 pages from a single 70ml bottle — equivalent to 20–30 traditional cyan cartridges. For an office printing 5,000 colour pages monthly (moderate colour use), the cyan bottle lasts 5–6 weeks, transforming colour printing from a budget concern into a routine, affordable business operation.

This is not bulk ink or third-party replacement. This is genuine Epson ink formulated specifically for Epson’s Micro Piezo printheads and the latest EcoTank L-series printer systems, ensuring compatibility, colour accuracy, and warranty protection.

Brilliant Dye-Based Cyan — Vivid Colour For Professional Output

The 101 cyan uses genuine Epson dye-based cyan ink, engineered to deliver the brilliance and vibrancy required for professional colour applications. Dye-based inks dissolve fully into the liquid carrier, enabling precise colour control and outstanding colour saturation — the vivid cyan that makes colour graphics pop on the page and gives colour documents professional authority.

This dye-based formulation excels in colour business applications: marketing collateral where colour brand accuracy is essential, business presentations where colour graphics convey information more effectively than black and white, educational materials where colour engages students and enhances learning, product packaging artwork where cyan is core to visual impact, and any colour printing where professional colour reproduction is non-negotiable. The brilliant cyan produced by the 101 ink ensures colour documents communicate professional quality and intentional design.

Ultra-High Page Yield — Up To 6,000 Pages From A Single Bottle

Six thousand colour pages from 70 millilitres of cyan ink is the defining advantage of the EcoTank system for colour printing. For an office printing 1,000 colour pages monthly (moderate colour use), the cyan bottle lasts six months. For schools or creative agencies printing 3,000 colour pages monthly, the bottle provides two months of uninterrupted colour output. This high yield means:

• Fewer interruptions for bottle replacements, enabling continuous colour printing workflows
• Dramatically lower cost per colour page (fractions of a penny for cyan within the overall colour print)
• Simplified colour ink inventory and supply chain management
• Continuous colour printing without supply constraints or budget rationing
• Environmental sustainability through 98% reduction in cartridge waste versus traditional systems

The high yield is achieved through precision: Epson’s Micro Piezo printing technology deposits tiny drops of cyan ink with exact precision, minimizing waste whilst maximizing colour coverage and hue accuracy. The result is economical colour printing that encourages routine use rather than rationing.

Vibrant Cyan Perfect For Colour Photography, Graphics, And Branding

The 101 cyan excels at rendering the full spectrum of cyan-dependent colours. Sky and water in colour photographs emerge with natural brilliance. Ocean imagery displays true-to-life depth and colour. Green and teal tones created by combining cyan with yellow appear vibrant and professional. Blue gradients render smoothly without banding. For any application where cyan is essential to visual impact — digital design colour printing, marketing brochures, business presentations, educational posters, or home colour photography printing — the 101 cyan delivers the brilliance that separates professional colour output from budget alternatives.

The cyan also provides essential shadow and highlight detail in full-colour printing. When combined with black ink, cyan contributes to rich blacks, deep greys, and the colour gradations that make colour photographs look true-to-life rather than flat or artificial.

Wide Printer Compatibility — Designed For Latest Epson EcoTank L-Series

The 101 cyan is compatible with the entire Epson EcoTank L4xxx and L6xxx printer lineup. L-series compatibility spans L4150, L4156, L4160, L4260, L6160, L6170, L6176, L6190, L6270, L6290, and L14150. This comprehensive compatibility means purchasing the 101 cyan is a safe investment that works across multiple Epson EcoTank printers, protecting your colour ink investment through equipment upgrades and multifunction printer deployments across offices.

EcoFit Technology — Mess-Free, Spill-Resistant Refilling

The 101 cyan features Epson’s engineered EcoFit bottle design with a spill-resistant nozzle specifically engineered to prevent spills during refilling. The nozzle geometry guides ink cleanly into the printer’s cyan tank without dripping onto hands, desk, or printer exterior. The nozzle design prevents air gaps and prevents the gurgling that causes spills in poorly-designed bottles.

The bottle is colour-coded bright cyan, eliminating accidental mis-filling into black or other colour tanks. Refilling takes seconds and requires no special tools or technical knowledge. For offices refilling colour ink multiple times weekly, this ease-of-use and spill prevention is invaluable, protecting equipment and workspace from colour staining whilst maintaining printing productivity.

Fast-Drying, Fade-Resistant Cyan — Professional Permanence

The dye-based cyan formulation includes a fast-drying additive that allows printed pages to dry immediately on standard paper, eliminating smudging when pages are stacked, collated, or handled immediately after printing. For offices producing high volumes of colour documents requiring immediate handling, binding, or distribution, this fast-drying capability is essential.

The dye-based formulation is also engineered for permanence. Cyan colour printed by the 101 ink remains vibrant and fade-resistant for years, even when exposed to light. Colour documents printed today remain professionally vivid and readable decades later — important for business branding, educational materials, and archival colour documents.

Genuine Epson Quality — Micro Piezo Precision And Warranty Protection

This is genuine Epson ink formulated specifically for Epson’s Micro Piezo printheads and the latest EcoTank printer technology. Epson’s Micro Piezo technology automatically senses nozzle conditions and adjusts cyan ink delivery to maintain consistent colour quality across thousands of pages. Using genuine Epson cyan ensures this technology operates optimally, delivering the colour accuracy and print consistency required for professional colour output.

Furthermore, using genuine Epson ink maintains your printer warranty. Many manufacturers restrict warranty coverage to genuine consumables; Epson’s warranty explicitly covers EcoTank printers using genuine 101 series inks (black, cyan, magenta, yellow). Third-party or non-genuine inks may void warranty protection and risk printer damage.

Part Of The Complete 101 Colour System — Cyan Plus Black And Colour Inks

The 101 cyan is the colour foundation of Epson’s complete 101 series. Used alone with black, the cyan enables professional colour documents, graphs, and graphics. Used in complete combination with black (101 black), magenta (101 magenta), and yellow (101 yellow), the inks enable full-spectrum professional colour printing at extraordinary economy.

Black yields 7,500 pages per bottle. Cyan, magenta, and yellow each yield 6,000 pages per bottle. This means a single set of 101 inks — one black, one cyan, one magenta, one yellow — delivers thousands of full-colour pages at a cost per colour page that makes professional colour printing routine and economical.

Environmental Responsibility — Sustainability Through Massive Yield

The EcoTank system, and specifically the 101 cyan, is engineered for environmental responsibility. By delivering 6,000 colour pages per bottle instead of 300 pages per traditional cyan cartridge, the system dramatically reduces plastic waste entering landfills. Over a year, an office printing 1,000 colour pages monthly would use 48+ traditional cyan cartridges or just one 101 cyan bottle — reducing cyan cartridge waste by 98 percent.

The concentrated cyan ink means fewer shipments, lower transportation emissions, and simplified supply chain management. For environmentally-conscious organisations, the EcoTank system delivers measurable sustainability benefits with no compromise on colour quality or professional output.

The Cyan That Powers Professional Colour Printing On A Budget

The Epson 101 Cyan Ink Bottle represents the triumph of the EcoTank philosophy for colour printing: professional-quality cyan at a cost so low that colour printing becomes routine and economical rather than a budget concern reserved for high-value documents. Without brilliant cyan, colour documents lack the vibrancy and professional polish that colour is meant to deliver. With the 101 cyan, colour is abundant, affordable, and of genuinely Epson quality.

Recommended Action: If you own an Epson EcoTank L4150, L4160, L6160, L6170, L6176, L6190, L14150, or compatible L-series printer and require professional colour printing for marketing materials, business presentations, colour photographs, educational graphics, or routine colour documents, invest in the Epson 101 cyan ink bottle and gain 6,000 pages of genuine, brilliant, fade-resistant cyan colour printing from a single 70ml bottle that redefines what affordable, professional colour printing truly means.

Stop rationing colour printing because traditional colour cartridges are expensive, stop choosing between colour output volume and budget constraints, stop accepting washed-out or artificial cyan from budget third-party inks — choose the Epson 101 Cyan and gain 6,000 pages of genuine, brilliant, professional cyan from a single 70ml bottle that enables continuous, economical, professional-quality colour printing across your entire organisation.

Professional black printing is the foundation of business documents. Sharp text on invoices, dark text on reports, crisp blacks on forms, and deep greys in graphics — all depend on black ink quality and volume. The Epson T6641 Black Ink Bottle delivers exactly this: 70 millilitres of genuine Epson dye-based black ink yielding up to 5,000 pages of sharp, fade-resistant black text and graphics from a single bottle. This is Epson’s replacement black ink for the EcoTank L-series and Expression ET-series printer ecosystem — a system engineered around the philosophy that high-volume black printing should be affordable enough for everyday office use, not rationed because cartridges are expensive. The T6641 black combines the sharp text clarity that makes Epson inkjet output professional-grade with the massive page yield that makes EcoTank printing economical for any office, school, or business printing need.

Why the Epson T6641 Black Is Essential For Professional EcoTank Printing

Black printing is where volume printing begins. Whilst colour printing grabs attention, black printing comprises the majority of office document production: invoices, reports, forms, reports, memos, and all the routine business documents that require professional appearance and reliability. The T6641 black is engineered specifically for this mission: delivering sharp, permanent black text and graphics that communicate professionalism and authority.

The EcoTank system fundamentally reimagines black printing economics. Traditional cartridge systems yield 300-500 pages at substantial cost; the T6641 yields 5,000 pages from a single 70ml bottle. For an office printing 10,000 pages monthly (busy but not industrial), the black bottle lasts just two weeks — eliminating constant cartridge purchasing, reducing inventory complexity, and enabling business-critical printing to continue without supply chain interruptions.

This is not bulk ink or third-party replacement; this is genuine Epson ink formulated specifically for Epson’s Micro Piezo printheads and Epson EcoTank systems, ensuring compatibility, quality, and warranty coverage.

Professional Dye-Based Black — Sharp Text And Deep Blacks

The T6641 uses genuine Epson dye-based black ink, engineered to deliver the sharpness and depth required for professional business documents. Dye-based inks dissolve fully into the liquid carrier, enabling precise colour control and sharp character reproduction — the definition and crispness that separates professional printing from amateur output.

This dye-based formulation excels in business applications: corporate documents where text sharpness communicates professionalism, financial reports where clarity is essential, contracts and agreements where legibility is non-negotiable, and any printing where black text must remain permanently readable for years or decades. The deep blacks produced by the T6641 ink ensure documents photographed or scanned later remain legible and professional-appearing.

Ultra-High Page Yield — Up To 5,000 Pages From A Single Bottle

Five thousand pages from 70 millilitres of ink is the defining advantage of the EcoTank system for black printing. For an office printing 5,000 pages monthly (moderate office use), the black bottle lasts one full month. For schools or government agencies printing 10,000 pages monthly, the bottle provides two weeks of uninterrupted printing. This high yield means:

• Fewer interruptions for bottle replacements
• Dramatically lower cost per page (fractions of a cent for black)
• Simplified ink inventory and supply chain management
• Continuous business-critical printing without supply constraints
• Environmental sustainability through fewer packaging and waste cycles

The high yield is achieved through precision: Epson’s Micro Piezo printing technology deposits tiny drops of black ink with extreme precision, minimizing waste whilst maximizing page coverage. The result is economical black printing that encourages routine use rather than rationing.

Wide Printer Compatibility — Extensive Epson EcoTank Ecosystem Support

The T6641 black is compatible with the entire Epson EcoTank ecosystem. L-series compatibility spans L100, L110, L120, L130, L200, L210, L220, L300, L310, L350, L355, L360, L361, L365, L380, L382, L385, L386, L405, L455, L475, L485, L486, L550, L555, L565, L575, L605, L655, L1300, L1455, plus L3050, L3060, L3070. Expression ET-series compatibility includes ET-2500, ET-2550, ET-2600, ET-2650, ET-3600, ET-4500, ET-4550, ET-14000, ET-16500.

This comprehensive compatibility means purchasing the T6641 is a safe investment that works across multiple Epson EcoTank printers, protecting your ink investment through equipment upgrades.

Fade-Resistant And Smudge-Free — Permanent, Professional Output

The dye-based black formulation is engineered for permanence. Black text and graphics produced by the T6641 remain legible and fade-resistant for years, even when exposed to light. Documents printed today remain professionally sharp and readable decades later — important for business records, contracts, and archival documents.

The fast-drying formulation means printed pages dry immediately on standard paper, eliminating smudging when pages are stacked, collated, or handled during binding. For offices producing high volumes of documents requiring immediate handling, this fast-drying capability is essential.

Genuine Epson Quality — Micro Piezo Precision And Warranty Protection

This is genuine Epson ink formulated specifically for Epson’s Micro Piezo printheads.

Mess-Free Refilling — Simple, Spill-Resistant Bottle Design

Refilling black ink should be intuitive and clean. The T6641 features Epson’s engineered bottle design with a spill-resistant nozzle that pours cleanly into the printer’s black tank without dripping onto hands, desk, or printer exterior. The nozzle design prevents air gaps and gurgling that cause spills in poorly-designed bottles.

Refilling takes seconds and requires no special tools or technical knowledge. The bottle is colour-coded black, preventing accidental mis-filling into the colour tanks. For offices refilling ink weekly or more frequently, this ease-of-use is invaluable.

Part Of The Complete EcoTank System — Black Plus Colour For Full-Spectrum Printing

The T6641 black is the foundation of complete EcoTank colour printing. Used alone, it enables sharp, professional black-and-white printing. Used in combination with cyan (T6642), magenta (T6643), and yellow (T6644), the inks enable full-spectrum colour printing at extraordinary economy.

Black combined with cyan and magenta creates rich blacks and dark greys. Black combined with colours enables shadow detail in colour photographs. For offices wanting the flexibility to print both pure black and colour documents, the T6641 plus colour bottles provides comprehensive printing capability.

Environmental Responsibility — Sustainability Through High Yield

The EcoTank system, and specifically the T6641, is engineered for environmental responsibility.
