Product Description

Caldron CJ 6800ES and CJ 5500ES solvent printers with 6x Seiko Alfa 25PL printheads, up to 4,500 Sqft/hr speed, 6.8m and 5.5m extra wide format. Best wide format printer for banner printing, hoardings, non-joint flex, large poster printing and vinyl stickers.

Caldron CJ 6800ES / CJ 5500ES | Seiko Alfa 25PL Solvent Printer

If your shop handles outdoor banners, hoardings, and building wraps that are wider than what a standard 3.2-metre machine can handle, the Caldron CJ 6800ES / CJ 5500ES is built for exactly that scale. This solvent printer is a heavy-duty wide format printer and large format printer that gives you a choice between 6800mm and 5500mm media widths — enough to print extra wide non-joint flex in a single pass without seaming panels together.

At its core, this machine runs up to 6 genuine Seiko SPT1024HG Alfa 25PL printheads in a staggered 3x4 layout, pushing out 1440 dpi resolution at speeds up to 4,500 Sqft/hr on the CJ 6800ES. That combination of width and speed makes it a serious piece of digital printing equipment for banner printing, large poster printing, sticker printing, vinyl stickers, and large format printing at a scale most shops cannot reach with smaller machines. It works as a flex printing machine, a printer for vinyl, and a production backbone for print on demand businesses that take on oversized orders. If you are searching for a large format printer or digital inkjet printer that handles the really big stuff — hoardings, billboards, full-building graphics — the CJ 6800ES and CJ 5500ES are among the most capable solvent printer options you can put on a production floor.

Key Features of Caldron CJ 6800ES / CJ 5500ES

✔ 6x Genuine Seiko Alfa 25PL Printheads

Six Seiko SPT1024HG Alfa 25PL heads in a 3x4 staggered layout deliver sharp 1440 dpi output with a longer printhead life — exactly what high-volume large format printing demands from a solvent printer.

✔ Up to 4,500 Sqft/hr Printing Speed

The CJ 6800ES hits 4,500 Sqft/hr and the CJ 5500ES reaches 4,300 Sqft/hr in high speed mode. For banner printing, outdoor banners, and large poster printing at this width, that is serious throughput.

✔ 6.8m & 5.5m Extra Wide Media Width

Choose the CJ 6800ES for 6800mm media or the CJ 5500ES for 5500mm. Both print extra wide non-joint flex in a single pass — no stitching, no weak seams on your flex printing machine output.

✔ 1440 dpi Staggered Printhead Layout

The staggered configuration keeps resolution high at 1440 dpi even when the wide format printer is running at full speed. Your poster printing and vinyl stickers look sharp up close.

✔ Full Infrared Heating & Drying System

Preheating, middle heating, front heating, front drying fans, and infrared heaters dry prints fast and evenly. When your printer for vinyl or solvent printer is running 4,500 Sqft/hr, this drying system keeps up.

✔ Heavy-Duty Industrial Body

A rugged heavy-duty frame keeps the carriage stable at top speed across a 6.8-metre span. For a large format printer running print on demand orders and sticker printing back to back, that stability is essential.

Caldron CJ 6800ES / CJ 5500ES FAQ

The best wide format printer for a print shop depends on the size of jobs you take on. If your shop regularly handles hoardings, building wraps, billboards, and extra wide outdoor banners that smaller machines simply cannot print in one piece, the Caldron CJ 6800ES / CJ 5500ES is one of the strongest options available. Its 6.8m and 5.5m media widths let you print non-joint flex in a single pass, which saves time and eliminates weak seam lines. With 6 Seiko Alfa 25PL heads and speeds up to 4,500 Sqft/hr, this solvent printer handles banner printing, large poster printing, sticker printing, and vinyl stickers at a scale that most large format printer machines cannot match. For shops that want to win the big contracts, this digital printing equipment is the kind of investment that pays for itself quickly.

The best printer for banners and signs needs three things: enough width to handle real-world banner sizes, enough speed for bulk orders, and a drying system that keeps production moving. The CJ 6800ES and CJ 5500ES deliver on all three. As a large format printer and digital inkjet printer, they print outdoor banners at 6.6m and 5.4m widths — no seaming required. At up to 4,500 Sqft/hr, your banner printing and large poster printing orders move fast. The infrared heating and drying system keeps flex printing machine output and printer for vinyl jobs dry and ready to ship. Whether someone finds you through a banner printing near me search or you are supplying signs for a national retail chain, this solvent printer has the width and speed to handle it all from one large format printing machine.

Starting a print shop comes down to a few clear steps. First, decide what you want to print — banner printing, poster printing, vinyl stickers, sticker printing, vehicle wraps, or a mix of everything. Second, find a space with enough room for a wide format printer, a cutting plotter, and material storage. Third, choose your core digital printing equipment — a solvent printer like the Caldron CJ 6800ES or CJ 5500ES if you plan to go after large outdoor banners, hoardings, and large format printing work, or a smaller 3.2m large format printer if you are starting with standard banner printing near me type local orders. Fourth, set up your design workstation with RIP software, get a cutting plotter for vinyl stickers and contour cuts, and add finishing tools like a laminator and grommet machine. Fifth, build a portfolio, set up a print on demand workflow, and start reaching out to local businesses, event organizers, and signage buyers. The key is picking the right printer for vinyl and banner work from day one so you do not outgrow your machine in six months.

Here is a practical list of equipment to start a printing business: a production solvent printer as your main wide format printer — the Caldron CJ 6800ES or CJ 5500ES if you want to handle extra wide outdoor banners and non-joint flex, or a 3.2m large format printer if you are starting with standard banner printing and large poster printing; a cutting plotter for sticker printing, vinyl stickers, and contour-cut graphics; a laminator for protecting prints that need extra durability; a heat press if you plan to add garment printing later; a small digital inkjet printer for short-run poster printing and sample prints; design workstations with RIP software like Maintop; and finishing tools including a grommet machine, trimmers, and a take-up system for your flex printing machine. The CJ 6800ES or CJ 5500ES as a printer for vinyl and large format printing covers the biggest revenue piece of that list — print on demand roll-to-roll production at a scale that wins bigger contracts. Start with the right digital printing equipment and you will not have to upgrade your main printer anytime soon.

The only real difference is width and the slight speed variation that comes with it. The CJ 6800ES handles 6800mm media width with a 6600mm print area and reaches up to 4,500 Sqft/hr. The CJ 5500ES handles 5500mm media width with a 5400mm print area and reaches up to 4,300 Sqft/hr. Both use the same 6 Seiko SPT1024HG Alfa 25PL printheads in the same 3x4 layout, the same solvent printer ink system, the same infrared heating and drying setup, and the same heavy-duty body. The choice comes down to what width your banner printing, outdoor banners, and large format printing contracts actually require. If you regularly print hoardings and building wraps wider than 5.5 metres, the CJ 6800ES is the right wide format printer. If most of your large poster printing, sticker printing, and flex printing machine work fits within 5.5 metres, the CJ 5500ES gives you the same Seiko Alfa performance at a lower price point. Both are serious digital printing equipment and both work well as a printer for vinyl and print on demand production machines.
