Independent service for cylinder and rotary screen engraving machines, laser and electromechanical alike. Including platforms where the manufacturer has limited its own support and the control computer has outlived its software.
Cylinder and screen engraving covers machines that do the same job by very different means, and the distinction decides what a service call looks like.
| Technology | How the cell or opening is made | What we work on |
|---|---|---|
| Electromechanical engraving | A diamond stylus cuts each cell into the copper at high frequency | Drive electronics, engraving head, mechanics, control system and its embedded software |
| Laser engraving | A laser removes material directly, with no cutting tool | Laser source, beam delivery, optics, motion, cooling and control |
| Rotary screen laser engraving | A laser opens the mesh or lacquer on a rotary screen | Laser source, beam delivery, optics, drum handling, cooling and control |
We will confirm which class your machine belongs to before quoting anything, because a diamond stylus head and a laser head have nothing in common beyond the frame they sit in.
Daetwyler no longer builds engravers. That lineage passed to Ohio Gravure Technologies, which publicly offers limited support for Ohio Electronic Engravers and MDC Daetwyler equipment and maintains a dated end-of-life list covering the 700 series, M811 and M820, M900, DTG and DTG-700, and the 850, 857 and Type D. In September 2024 it also ended support for the embedded Fedora-based control software and the RTIs that run on it. That last item is the interesting one for an owner: it orphans the control computer rather than the mechanics, and a control retrofit is usually a more realistic answer than chasing a discontinued operating system.
SPGPrints, formerly Stork Prints, has a screen engraving installed base going back to the mid 1980s. The current MAPLE, LARCH and ASPEN platforms replaced bestLEN, ecoLEN, smartLEX, rotaLEN, rotaLEX and the Helios and LE2000 machines before them. SPGPrints publishes that LARCH is field-upgradable to full MAPLE performance, which is worth knowing before anyone quotes a replacement.
Many gravure and screen operations also run digital flexo platesetters. Those are covered on the flexo plate imaging page, including the Esko CDI family and the Hell PremiumSetter.
Pulsed fiber laser cleaning in the near infrared, used to clear cells on anilox rolls and to strip print cylinders. Flexo Wash states that it continues to service its installed LaserX and LaserX2 units, so on those machines we are an option for capacity and response time rather than a replacement for the manufacturer.
Most of the non-Esko engraving and imaging brands in this sector now sit inside a single group. Hell Gravure Systems, Lüscher, Kaspar Graphic Solutions, Schepers, Daetwyler Graphics and Ohio Gravure Technologies are all under Heliograph Holding, which also holds a majority of Glunz & Jensen.
That is a matter of public record and it is not a criticism of any of those companies. For an equipment owner it has one practical consequence worth planning around: a single group relationship covers a large share of the machines in a typical plant. An independent option is useful when that relationship does not fit the timeline, the scope or the budget of a specific job.
Repair on this equipment is not one job. It is a set of different jobs, and which one you need depends on what the evaluation finds. The table below is the honest version of what that work looks like: what gets opened and put right, and what gets taken out and replaced. Which column a given fault lands in is decided by measurement, not by preference.
| Subsystem | What typically gets repaired | What typically gets replaced |
|---|---|---|
| Engraving laser source | Output measured against reference, cooling and connections corrected, protective optics attended to | Source modules, pump diodes, output and protective windows, collimators, fiber cables |
| Modulator and drive | Drive level returned to range, driver boards repaired at component level | Modulator assemblies, driver amplifiers, RF cabling, driver control boards |
| Engraving head and optics | Beam path cleaned and realigned, focus and standoff reset, head mechanics freed and reset | Lenses, mirrors, protective windows, focus assemblies, head optical and mechanical components |
| Cylinder handling and spindles | Runout and concentricity corrected, spindle and headstock alignment reset, clamping restored | Spindle bearings, chucks and clamping hardware, drive belts and couplings, support rollers |
| Motion and drives | Axes recalibrated, pitch and registration corrected, drive tuning restored | Bearings, ball screws, rails, servo motors, drives, encoders, limit switches |
| Extraction and cooling | Debris extraction flow restored, cooling circuits flushed and returned to spec | Blowers, filters, ducting, chiller pumps, heat exchangers, hoses, sensors |
| Control and electrical | Harnesses repaired, I/O traced, engraving configuration restored from your own backups | Control PCs and storage, HMI panels, motion and interface boards, sensors, interlocks, safety relays |
Two rules run through all of it. Anything we replace is documented with what came out and what went in, and anything we repair is validated by measurement afterwards rather than by whether the machine switches on. If a part turns out to be a failed custom assembly with no substitute available, we say so in writing instead of billing an attempt.
A discontinued part is a sourcing and engineering problem, not automatically the end of the machine. Depending on the item, the route is a current-production equivalent fitted and verified, a qualified substitute with the differences written down, a harness or cable made to suit, or a board repaired at component level because the board itself is no longer sold. We tell you which of those we are proposing before you approve it.
Class 4 work is planned and executed under a project-specific laser safety plan, with the engineering controls, personal protective equipment, beam management and facility conditions defined in writing before any energized optical work begins. On a customer site, final hazard analysis and approval stay with the plant's own safety function.
PhaseX Laser Services is an independent third-party service provider, not affiliated with or authorized by Esko, Miraclon, Kodak, Hell, SPGPrints, Domino, Videojet, Markem-Imaje or any other manufacturer named on this page unless expressly stated in writing. Brand and model names identify equipment only.
Both types are in service and they are completely different jobs. The classic HelioKlischograph and the Ohio and Daetwyler engravers are electromechanical: a diamond stylus cuts the cells. Laser engraving of gravure cylinders is a separate, newer class of machine. Tell us the model and we will tell you which you have before anything is quoted.
That is a common position in this market and it does not mean the machine is finished. These are mechanical, optical and electronic systems with identifiable subsystems. The harder problem is usually the embedded control software and the computer it runs on, and that is an area where a retrofit is often more realistic than a repair.
Sometimes. At least one current platform is published as field-upgradable to the performance of the model above it, and older machines can often take a control or drive retrofit rather than a full replacement. Whether it applies to your serial number is established by inspection.
No. We are an equipment service company. We work on the machine that does the engraving, not on producing your cylinders or screens.
Send the machine and model, the serial number, and what the control system is running. We respond with the next step and a fixed evaluation fee before anyone travels.
