Canon imagePROGRAF GP‑4600S (44″)

Canon imagePROGRAF GP-4600S (44")

The Canon imagePROGRAF GP-4600S is a 44" graphic production printer designed for mid to high-volume environments where wide-format colour accuracy, fast poster throughput and robust daily use are non-negotiable. Powered by Canon's 7-colour LUCIA PRO II pigment ink system — including Orange and Grey — it delivers near-Pantone gamut coverage on a machine built for production-grade workloads. From retail display and trade show graphics to banner artwork and franchise print programmes, the GP-4600S handles commercial colour with the kind of consistency that builds client confidence.

Why teams choose the GP-4600S

• 7-colour LUCIA PRO II inks: Orange and Grey channels push the gamut significantly beyond standard CMYK, achieving approximately 96% PANTONE Solid Coated coverage for brand-accurate output.
• 44" print width: produces A0 and B1 posters, wide banners, exhibition panels and retail display graphics at full width without piecing or stitching.
• Dual-roll support: two roll positions allow automatic media switching between jobs, dramatically reducing downtime in environments that print on multiple stocks throughout the day.
• Free-size borderless printing: full-bleed output eliminates trim waste on production poster runs, saving both media and finishing time.
• Mirrored ink layout: Canon's symmetric cartridge arrangement ensures balanced ink delivery across the full 44" width, reducing banding risk during extended production runs.
• Interior LED lighting: clear visibility inside the print chamber for confident media loading and rapid fault identification.
• Automatic nozzle compensation: the printer detects and compensates for non-firing nozzles mid-job, maintaining output quality without stopping the run.
• EPEAT Gold certification: responsible energy use and eco packaging for businesses with sustainability commitments.

Technical specifications

The LUCIA PRO II ink system: Orange and Grey explained

The core challenge in commercial poster printing is reproducing brand colours accurately and consistently. Standard 4-colour CMYK printing cannot hit many of the warm reds, oranges and vibrant hues that appear in brand guidelines and Pantone swatch books. Canon addresses this with two extra ink channels:

• Orange ink: fills the gamut gap between Red and Yellow that CMYK cannot bridge. Corporate oranges and reds, vivid event graphics, warm-toned photography and Pantone spot-colour approximations all benefit directly from this channel. It is why the GP-4600S achieves approximately 96% PANTONE Solid Coated coverage.
• Grey ink: produces neutrally balanced grey tones without the colour cast that results from mixing grey using Cyan, Magenta and Yellow inks. This matters for monochrome images embedded in colour jobs, neutral grey brand elements and shadow detail in mixed graphics work.
• All-pigment chemistry: every ink is pigment-based, giving finished output scratch resistance, indoor light-fastness rated for decades of display, and water resistance that makes the GP-4600S suitable for semi-outdoor and retail window environments.

Who is the GP-4600S for?

The GP-4600S sits at the centre of Canon's GP range — wide enough for full A0 and B1 production, with the throughput and dual-roll capability that serious graphic production requires. Typical users include:

• Sign and display shops: fast poster production with consistent colour across batches, dual media loading for mixed-stock days, and borderless output for full-bleed display graphics.
• Retail and franchise print programmes: centralised or in-store production of point-of-sale graphics, window displays and seasonal campaign materials, all Pantone-matched to brand standards.
• Trade show and exhibition producers: wide-format panel printing, retractable banner artwork and display systems in accurate, vibrant colour at production speeds.
• Marketing service bureaux: short-run and medium-run graphic production for multiple clients from a single machine, with media flexibility and colour consistency that supports a premium service offering.
• In-house corporate print rooms: a step up from desktop production for organisations that need consistent branded output at scale without outsourcing to a trade printer.

Workflow and media capabilities

The GP-4600S accepts a wide range of coated and uncoated media: poster and photo papers, backlit film, plain bond, tracing paper, vinyl-coated stocks and fabric roll media within the supported thickness range. Workflow features that support production efficiency include:

• Auto roll-width detection: the printer reads the loaded roll width automatically, reducing setup time between jobs and eliminating media-mismatch errors.
• Borderless custom sizing: free-size borderless mode produces edge-to-edge output on custom widths, cutting trimming requirements and reducing media wastage.
• USB direct print: PDF and JPEG files print directly from a USB drive, bypassing the print queue for quick jobs or emergency reprints without a connected workstation.
• Queue management: the onboard 500 GB HDD and 3 GB RAM support multi-job queuing, keeping the printer working while the next job is being prepared at the workstation.
• Canon PosterArtist integration: Canon's production-oriented layout software is compatible with the GP-4600S, enabling straightforward poster and signage layouts without a dedicated RIP for standard production workflows.

GP-4600S — Frequently asked questions

What is the maximum print width of the GP-4600S?

The Canon imagePROGRAF GP-4600S prints at a maximum width of 44" (1,118 mm). This covers A0 (841 × 1,189 mm) and B1 (707 × 1,000 mm) in portrait orientation, along with standard banner widths and custom graphic sizes up to the 44" limit. For 60" production requirements, the GP-6600S is the appropriate model in this range.

How does the GP-4600S compare to the GP-2600S?

Both printers share the same LUCIA PRO II 7-colour ink system and core feature set. The GP-4600S is the larger machine at 44" versus the 24" GP-2600S, making it the right choice when you regularly need A0 or B1 output, or where print width is the primary production consideration. Both offer dual-roll capability, borderless printing and EPEAT Gold certification. The GP-2600S is the more compact and cost-effective option for studios where 24" width is sufficient.

What Pantone coverage does the GP-4600S achieve?

With the Orange and Grey ink channels added to the base CMYK set, the GP-4600S achieves approximately 96% coverage of the PANTONE Solid Coated palette on suitable coated poster media. This makes it a practical choice for brand-critical work including retail point-of-sale materials, franchise print programmes and corporate signage where colour accuracy to a specific Pantone reference is required.

Does the GP-4600S come with any software?

Canon includes drivers for Windows and macOS, along with access to Canon PosterArtist — a production-oriented design and layout tool suited to poster and signage workflows. For more advanced RIP and colour management, the GP-4600S is compatible with third-party RIP software from leading suppliers. RGB UK can advise on the right software configuration for your workflow.

What maintenance does the GP-4600S require?

The GP-4600S uses a user-replaceable PF-10 print head, and a maintenance cartridge that collects waste ink and needs replacing periodically. Onboard nozzle-check and automatic compensation routines reduce the frequency of manual head-cleaning cycles compared to older Canon large-format models. RGB UK stocks all maintenance consumables and can provide guidance on servicing schedules based on your print volume.

Is finance or leasing available for the GP-4600S?

Yes. RGB UK offers finance and leasing options for the GP-4600S to UK business customers. A monthly lease spreads the cost and keeps the printer in your operational expenditure rather than capital budget. Contact our sales team for a quote tailored to your usage and term requirements.
