How to choose an eco-solvent printer

An eco-solvent printer is chosen by three things, in this order: the widest roll you print regularly, the square metres you print each month, and the room it will work in. Use the selector for a recommendation with the number of heads and the printing hours, or read on: the guide explains how the printer works, which media and print modes to plan for, what happens after printing, and compares the eco-solvent printers we supply using their manufacturer's published figures.

Which eco-solvent printer, and how many heads?

Three questions: roll width, the work you print and your monthly volume. We show the printer, the number of heads and the printing hours it implies.

What is the widest roll you print regularly?

What eco-solvent prints well

Eco-solvent ink bonds into solvent-compatible roll media and stays flexible once dry. That makes it the established choice for graphics that are stretched, rolled or installed outdoors.

Wraps and decals

  • Vehicle wraps, fleet graphics and window decals on self-adhesive vinyl
  • The print stretches with the film over curves and rivets

Banners and mesh

  • Frontlit and backlit banner, mesh for scaffolding and buildings
  • Up to 3.2 m wide in one piece on the UD-3200BE

Posters and point of sale

  • Paper and other coated roll media
  • Indoor prints viewed up close, in standard or quality mode

Know the limits

  • Roll media only: no rigid boards
  • Our eco-solvent models print CMYK, without white
  • Prints need drying time; the room needs ventilation

If you also print rigid boards or need white ink, read our guide to printing technologies first: a UV hybrid or roll-to-roll printer may be the better first machine.

How an eco-solvent roll printer works

Supply rollHeated platenPrint carriageDryer: fan + IRTake-up rollMedia direction
The media unwinds from the supply roll, is held flat and warmed on the platen while the carriage prints across it, then passes the dryer and winds onto the take-up roll. The UD-3200BE has triple media heating and a combined fan and infrared dryer, with the take-up included.
  • The carriage moves across the media and the heads lay the ink in several passes. The more passes, the finer the result and the lower the output.
  • Heating and drying start the evaporation of the solvent on the printer, so the print can be wound up. Full drying continues afterwards, off the printer.
  • Media transport: on a wide printer, keeping the media straight matters most. The UD-3200BE drives its pressure rollers electrically and controls them from four points; the CL models run the carriage on a linear rail, with 8 mm of height adjustment for thicker media and anti-collision guards on both sides.
  • The RIP prepares the files, manages colour and sends the job to the printer. Our eco-solvent printers work with FlexiPrint.

Step 1: choose the print width

Start from the widest job you print regularly, not the occasional one. A wider printer also prints narrow rolls, but it takes more floor space and more media in stock.

Print widthTypical workOur printerMachine size
1600 mmDecals, vehicle graphics and posters on standard vinyl rollsUD-16R2CL, one or two Epson i3200-E1 heads2716 × 718 × 1675 mm, 200 kg

Leave working space around the machine for loading rolls and handling prints, and a separate area where prints can dry before they are laminated or rolled up.

Step 2: print modes and the number of heads

A print mode sets how many passes the carriage makes over each strip of media. Fewer passes print faster; more passes print finer detail and smoother solids. The manufacturer publishes three modes for the CL printers, measured with one head on the 1.8 m model:

ModePassesOutput, one headTypical use
Draft334 m²/hBanners and mesh viewed from a distance
Standard426 m²/hMost signage, decals and vehicle graphics
Quality617 m²/hPosters, point of sale and graphics viewed up close

To size the printer, divide your monthly square metres by the output of the mode you print in most. The table gives the printing hours a month with one head on the 1.6 or 1.8 m printer, before media changes, nozzle checks and maintenance:

Monthly volumeDraft (34 m²/h)Standard (26 m²/h)Quality (17 m²/h)
500 m²about 15 habout 19 habout 29 h
1,000 m²about 29 habout 38 habout 59 h
2,000 m²about 59 habout 77 habout 118 h
4,000 m²about 118 habout 154 habout 235 h
  • One head suits most shops up to about 1,000 – 1,500 m² a month, depending on the mode.
  • Two heads on the UD-16R2CL or UD-18R2CL raise the output when the hours no longer fit your shifts, or when urgent jobs wait behind long banner runs. We confirm the two-head figure for the modes you print in.
  • The UD-3200BE takes one to four heads; in the top configuration it is rated at 118 m²/h in draft mode (3 pass). Choose the heads for the volume you expect in the next years: they are part of the configuration you order.

Step 3: know your media

Eco-solvent needs solvent-compatible media: the ink has to bond into the surface. Before a large order of a new roll, print a test strip and let it dry. The UD-3200BE lists frontlit, backlit, mesh, self-adhesive vinyl and paper among its media.

MediaUsed forMode and settingsAfter printing
Cast self-adhesive vinylVehicle wraps over deep curves and recessesStandard or quality; let the print dry fullyLaminate with a matching cast film before installing
Calendered self-adhesive vinylFlat decals, window graphics, signs and short-term promotionsStandardLaminate when it will be handled or used outdoors; contour-cut

Step 4: plan drying, finishing and the room

  1. 1Print

    Eco-solvent CMYK on roll media, in the mode the job needs.

  2. 2Dry

    Several hours to a day before lamination, by coverage, media and room.

  3. 3Laminate

    Protects wraps, floor graphics and outdoor prints.

  4. 4Cut

    Contour-cut decals and panels on a cutting table or plotter.

  5. 5Install

    Applied on site: on the vehicle, the window or the frame.

From print to installation in five steps: print, let the print dry, laminate, contour-cut, then install on the vehicle, window or frame. Banners usually skip lamination and cutting.
  • Drying: eco-solvent prints need from several hours to a day to dry before lamination, depending on ink coverage, media and room conditions. Laminating too early traps solvent under the film.
  • Ventilation: plan air exchange in the printing room for the solvent odour, as for any solvent-based process.
  • Lamination: wraps, floor graphics and outdoor prints are usually laminated. The L1-1700 roll laminator works up to 1630 mm wide, at up to 52 m/min, and slits the roll in the same pass.
  • Cutting: contour-cut decals and panels need a cutter after printing. The Jwei SL cutting table cuts self-adhesive vinyl, vehicle wrap film, banner and boards, with camera positioning to register the print.
  • Room conditions: the UD-3200BE is specified for 18 – 30 °C and 35 – 65% relative humidity. Keep the media in the same room, so it is at room temperature when it is loaded.
  • Power: the eco-solvent printers in this guide run on single-phase 220 V, at 3.3 – 3.4 kW.

Daily care and maintenance

  • Nozzle check at the start of every shift: print the test pattern before the first job, and clean only when it shows missing nozzles.
  • Keep the printer working: eco-solvent printers prefer regular use; follow the manufacturer's routine for idle days and weekends, which we show at training.
  • Capping station and wiper: clean them on the schedule in the manual; they keep the heads sealed and wiped between jobs.
  • Dust: keep the room clean and the media covered. Dust and fibres on the media are a common cause of head strikes and missing nozzles.
  • Media edges and height: set the carriage height for the media you load, and use the edge guards on thin vinyl, so curled edges do not touch the heads.

Common mistakes

  • Buying for the widest job you might get once a year. Print the occasional oversize job in sections, or buy for it when it becomes regular.
  • Sizing on draft figures for work printed in quality mode. Quality mode prints at half the draft output; compare in the mode you use.
  • Laminating too early. Solvent trapped under the laminate can cause bubbles and lifting later.
  • No space for drying. Without it, finished prints wait on the take-up roll and slow the whole shop.
  • Untested media. Not every vinyl or banner is made for eco-solvent ink; test a strip before a large order.

Eco-solvent or UV on the roll?

If your work is mostly wraps and long banner runs, eco-solvent is the usual choice. If jobs must leave the same day, if you need white ink, or if you also print rigid boards, compare it with UV roll-to-roll and hybrid printers in our guide to printing technologies and our UV printer guide.

Glossary

  • Pass: one movement of the carriage over a strip of media. A 4-pass mode covers each strip in four passes.
  • Draft, standard, quality: the print modes, from fastest to finest.
  • Frontlit and backlit: banner lit from the front, and banner or film lit from behind in a light box.
  • Mesh: perforated banner that lets wind through, for scaffolding and buildings.
  • Cast and calendered vinyl: cast film is thinner and conforms to deep curves; calendered film suits flat surfaces.
  • Take-up: the motorised roll that winds the printed media after the dryer.
  • CISS: continuous ink supply system: bulk ink containers feeding the heads.
  • RIP: the software that prepares files, manages colour and drives the printer.

Before you order

  • Send us what you print, the media, the widest roll and your monthly square metres. We recommend the width and the number of heads.
  • Check the room: floor space for the printer and for drying, ventilation, and a stable single-phase supply.
  • Installation, operator training and technical service are available and quoted per machine and country.
  • You can see printers running in our Bucharest showroom, by appointment.

Frequently asked questions

How many print heads do I need?

Divide your monthly square metres by the output per head in the mode you print in. With one Epson i3200-E1 head, the 1.6 m and 1.8 m printers are rated at 34 m²/h in draft, 26 m²/h in standard and 17 m²/h in quality mode. If the hours do not fit your shifts, add a head.

What does a pass mean, and which mode should I print in?

A pass is one movement of the carriage over a strip of media. Draft (3 pass) suits banners seen from a distance, standard (4 pass) most signage and vehicle graphics, quality (6 pass) posters and prints viewed up close.

Can an eco-solvent printer print white?

Not the eco-solvent models we supply: they print CMYK. For white on transparent or coloured media, look at UV roll-to-roll or hybrid printers with a white channel.

Can eco-solvent print on rigid boards?

No. Eco-solvent printers print roll media. Rigid boards are printed on a UV flatbed or hybrid printer, or with a printed vinyl laminated onto the board.

How long do eco-solvent prints need before lamination?

From several hours to a day, depending on ink coverage, media and room conditions. Laminating too early traps solvent under the film.

Can I print backlit graphics with eco-solvent?

Yes, on backlit banner or film. Backlit prints use a denser ink setting so that the colour holds when the light box is on; check a sample on the light box before the run.

Do I need ventilation for an eco-solvent printer?

Yes. Plan air exchange in the printing room for the solvent odour, as for any solvent-based process.

Which software runs the printers?

Our eco-solvent printers work with the FlexiPrint RIP, which prepares the files, manages colour and sends the jobs to the printer.

Send us what you print, the roll widths you use and your monthly volume, and we will recommend the width and the number of heads.
