If you have ever installed a backdrop or wall mural made of several printed panels, you know the moment of truth. The panels go up side by side, and you find out whether the lettering lines up across every seam. A few millimetres of length difference between panels, or a slight colour shift from one panel to the next, is enough to spoil the finished graphic and send you back to reprint.
For print service providers, tiled jobs are everyday work: event backdrops, hoardings, billboards, exhibition walls and wallcoverings. So when Roland DG launched the TrueVIS AG-640, the world's first latex printer/cutter, we wanted to answer one question before anything else: how well does it tile?
We printed a 6.5 m × 4 m graphic as five panels, joined them on the floor and measured every edge. Here is what we found.
Watch the Test
How We Set Up the Test
- Artwork: one 6.5 m × 4 m graphic with large text running across the full width
- Tiling: split into 5 panels, each about 1.3 m wide × 4 m long
- Print mode: Generic Vinyl · Standard · True Rich Standard
- Inks: CMYK + Orange + Red + Optimiser
- Production: all five panels printed in one run, with the take-up system rolling up the print
After printing, we laid the five panels side by side on the floor, joined them and measured the left and right edge of every panel against the 4,000 mm target. That gave us 10 measurement points in total.
The Results: Every Panel Within 3 mm
| Panel | Left edge (mm) | Right edge (mm) |
|---|---|---|
| 1st (leftmost) | 4,001 | 4,003 |
| 2nd | 4,002 | 4,003 |
| 3rd | 4,002 | 4,002 |
| 4th | 4,003 | 4,003 |
| 5th (rightmost) | 4,002 | 4,003 |
Target length: 4,000 mm per panel.
All 10 points landed between 4,001 mm and 4,003 mm. That is a maximum deviation of 3 mm over 4 metres, which is less than 0.08%. Just as important for tiling, the panels were consistent with each other: no two panels differed by more than 2 mm, and the left and right edges of each panel were within 2 mm, so the joins run straight from top to bottom.
On the floor, the result was what installers want to see. There was no visible colour shift between panels, and the text stayed aligned across every seam.
For a print shop, that consistency means less trimming and adjusting on site, faster installation and fewer reprints of a single panel that does not match the rest.
Print Speed and Ink Cost
| Printing time | 3 h 38 min (218 min) |
| Print area | 26 m² (6,500 × 4,000 mm) |
| Print speed | 7.16 m²/h (77 ft²/h) |
| Total ink used | 129.94 ml |
| Ink per area | approx. 5.0 ml/m² |
| Ink cost for the job | approx. RM76, under RM3 per m² |
Because the artwork was mostly purple with white lettering, nearly all the colour ink was magenta (42.56 ml) and cyan (31.67 ml), with only traces of red and yellow. The optimiser accounted for 55.11 ml, laid down across the printed area to fix the ink to the media.
These figures apply to this test only. Different media, artwork and print-mode settings will give different results.
More Than a Tiling Printer
Tiling accuracy is only part of the story. According to Roland DG, the TrueVIS AG-640 also brings:
- Integrated print and cut: the first latex printer with built-in contour cutting, for stickers, labels and decals without a separate cutter
- 64-inch (1,625 mm) print width for signage, display, vehicle, window and interior graphics
- TA2 water-based latex inks: CMYK plus Orange and Red for a wider colour gamut, and a dense White ink for window and transparent graphics
- Long-life piezo printheads for lower ownership costs and consistent output over time
- Instant-dry prints with no outgassing, so jobs can be finished and installed straight away
- Broad media support, with 120 third-party media tested by Roland DG
- VersaWorks 7 RIP and Roland DG Connect for production management and printer monitoring
Who Should Take a Look
- Print service providers producing backdrops, murals, hoardings and other multi-panel jobs where seams must match
- Sign makers who want latex output and contour cutting in one machine
- Shops short on floor space that would rather run one printer/cutter than a printer and a separate cutter
Frequently Asked Questions
How accurate is the Roland AG-640 for tiled prints?
In our test, five 4-metre panels all printed within 1–3 mm of the target length, with no more than 2 mm difference between panels and no visible colour shift across the seams.
Can the AG-640 print and cut?
Yes. The TrueVIS AG-640 is a latex printer with integrated contour cutting, so you can print and cut stickers, labels and decals on one machine.
What inks does the AG-640 use?
Roland DG TA2 water-based latex inks in CMYK, Orange, Red and White, plus an optimiser.
Do AG-640 prints need drying time before lamination or installation?
No. Latex prints come off the printer dry with no outgassing, so they can be finished right away.
Where can I see the AG-640 in Malaysia?
Contact DPI Technology to arrange a demonstration. You are welcome to bring your own artwork and media.
