EUmark Set 03 — etch marking kit built for continuous use
Most marking systems arrive with sample quantities of everything. The samples run out during the first real job, the reorder takes a week to arrive, and the machine sits on a shelf in the meantime. Set 03 is built so that does not happen.
It is the full marking unit with the 58 mm stencil printer, shipped with six rolls of stencil tape and two marking felt sheets — a working stock, not a starter sample. This is the configuration to specify when marking is going to be part of the daily routine from day one, not something you’re evaluating.
The full machine, not the compact one
Set 03 runs both marking modes:
- Black oxide marking — shallow, high-contrast dark mark. What most identification work calls for.
- Deep etch, light marking — a recessed mark with real depth, for identification that has to survive further finishing, handling, media blasting or years of service wear.
The compact sets — 05, 06 and 07 — produce black marking only. If a drawing calls out etch depth rather than contrast, or the mark has to outlast abrasive handling, the full machine is what covers it.
What the P58D printer is good at, and what it is not
The 58 mm printer produces excellent text, serial numbers, part numbers, date codes and fine line artwork. Thin strokes transfer cleanly, which makes it the right tool for the identification work most shops actually do, and for outline logos.
It is not the printer for machine-readable symbols. QR codes, barcodes, thick strokes and large solid black areas should be avoided at this width — they do not transfer reliably. If your marking has to carry a scannable code, SUPER SET 04 and Set 07 use the wider printers and the software built for it.
Why six rolls, not one
A single roll of stencil tape gets a shop through evaluation and the first few jobs. It does not get a shop through a quarter of production marking. Set 03 ships with six — enough that consumables stop being something you have to think about for months, and enough that the two marking felts included will not outlast the tape supply, which is the usual failure point in a starter kit.
If Set 02 is the version of this machine you try, Set 03 is the version you run.

Step up to SUPER SET 04 if you need the wider 100–115 mm printer, a 108 m tape roll and full 200 ml bottles of every electrolyte instead of the standard fill — the configuration built for high-volume production and for shops that also need scannable codes.
What the process does to the part
| Property | Effect | Why it matters |
|---|---|---|
| Heat input | none | No HAZ to disposition on heat-treated or age-hardened alloys |
| Recast layer | none | No micro-cracking initiation site on cyclically loaded parts |
| Residual stress | none added | Fatigue allowables unchanged |
| Material removal | ~0.001″ surface conversion | Safe on thin wall sections and finished dimensions |
| Burrs and raised edges | none | No deburr operation after marking |
| Hardness and temper | unchanged | Marking happens last, on the finished part |
| Corrosion resistance | preserved | Neutralize with N11, then passivate to your existing procedure |
The four fluids
Marking units are broadly similar across the industry. Electrolytes are not, and they are where the result actually comes from.
| Fluid | How it behaves | Reach for it when |
|---|---|---|
| M21 | Self-cleaning. Gets a high number of marks out of one wetting of the felt. | Running a batch. The operator is not stopping to re-wet or wash the felt between parts — which is where the real cycle time in manual marking gets lost. |
| M22 | Very dark mark, and the fluid used for deep etch. Requires the felt to be washed after use. | Maximum contrast, or a print calling for etch depth rather than surface contrast alone. |
| M23 | Non-corrosive, formulated for marking highly corrosion-sensitive materials. Wipe with a dry cloth after marking — that is the whole post-process. | Corrosion-critical hardware, or any part where a wet neutralizing step is impractical. |
| N11 Neutralyte | Protects the marked surface after etching. | Standard finishing step after M21 or M22. |
Read this before you order: the table is a recommendation, not a specification. Alloy, condition, finish and prior processing all change the outcome, so trial marking on your own material is a required step. Send a coupon and we will run the first trial for you.
Every fluid ships with a safety data sheet. Quality and EHS functions need those for incoming inspection, hazard communication and the audit file — in a regulated shop an undocumented consumable does not get approved for the floor, however well it performs. The fluids are formulated to the requirements applied in medical, aerospace and food-contact manufacturing. A 200 ml bottle delivers up to 20,000 marks.

Artwork that works
Thin lines, outlined text and open lettering reproduce best, whether printed or photo-etched. Thick strokes and large solid black areas should be avoided: the electrolyte does not pass evenly through them and the mark comes out patchy. Where a logo is heavy, an outlined version marks far better than a filled one. Strokes below about 0.008″ (0.2 mm) tend to close up.
For long-life photo stencils, send artwork as SVG, DXF, AI or EPS with the part finish, and we will tell you what will hold before you commit.
Running the numbers
Six rolls at 10 m each is 60 m of stencil tape — at a typical stencil length, several hundred printed stencils before a reorder. A 200 ml bottle of electrolyte covers up to 20,000 marks. For a shop running a few hundred parts a month, consumables stop being a line item worth tracking closely for the better part of a year.
Questions we get
What’s the real difference between Set 02 and Set 03?
Consumable stock. Same machine, same printer, same electrolytes. Set 02 ships with one roll of tape and one marking felt; Set 03 ships with six rolls and two felts. If you are evaluating the process, Set 02 is enough. If you already know you’ll be marking regularly, Set 03 is the better buy for a small difference in price.
Can I mark hardened and age-hardened parts?
Yes, and that is the main reason customers move to this process. There is no thermal or mechanical input, so hardness, temper, geometry and fatigue life are unaffected. Marking is performed on the finished, final-inspected part.
Can the printer produce a data matrix or QR code?
Not reliably at 58 mm. Codes need the wider printers in SUPER SET 04 or Set 07. The P58D is a text and fine-line printer, and it is very good at that.
Does marking affect corrosion resistance on stainless?
Not when the marked area is neutralized with N11 and passivated along with the rest of the part under your existing procedure. Confirm it once on a coupon during qualification and record the result.
Where does it ship from, and what will landed cost be?
Orders dispatch from Serbia and ship worldwide. Duties, tariffs and import handling vary by destination and change often. Tell us the delivery country before you order and we will provide the tariff classification, the shipping method and a landed cost estimate in writing.
Before you buy
Send the alloy, part geometry, mark content and annual volume, and we will confirm the right configuration — including telling you if a different set fits better.
