The Setup: Why I Started This Comparison
When I first got my xtool s1, I was basically convinced that color engraving was a gimmick. Everything I'd read said that for a desktop machine in this price range, you're better off sticking to monochrome—grayscale, simple logos, text. That the color stuff was for industrial units or for people with way more patience than me.
Honestly? I was wrong. But it took me about 9 months and probably around $400 in wasted material to figure out when color engraving on the xtool s1 actually makes sense, and when you're just burning time and acrylic.
To be fair, the conventional wisdom isn't totally wrong. It's just... oversimplified. Color engraving has specific use cases where it's genuinely a game-changer. And monochrome still wins for a lot of standard jobs. The trick is knowing which is which.
I'm not a laser engineer, so I can't speak to the optics science behind it. What I can tell you, from the perspective of someone who's run maybe 150 orders through an xtool s1 and screwed up a fair number of them, is the practical difference.
Dimension 1: Setup Complexity—Color vs. Monochrome
Monochrome Engraving Setup
If you're doing a standard black engraving on acrylic, wood, or leather, the setup is basically:
- Pick your material preset
- Run auto-focus
- Hit go
That's it. I've done this on 50+ orders and I'd say 90% of them require zero tweaking to the default settings. The xtool s1 handles it well. With the 20W laser module, I can do a decent depth engrave on cherry wood in one pass at about 3000mm/min. Fine for logos, text, barcodes.
Color Engraving Setup
Okay, so color engraving on the xtool s1—specifically using the 40W laser module for anodized aluminum or the CO₂ module for coated metals—is a different beast entirely.
First, you absolutely need the right material. Not all "laserable" metal sheets will produce consistent color. I learned this the hard way: On a $320 order where every single item came out with a greenish tint instead of the requested deep blue. The client was, understandably, not thrilled. That was a rush redo and a 1-week delay.
The settings are way more finicky. For color engraving on anodized aluminum with the 40W module, I've found the sweet spot is around:
- Speed: 800-1200mm/min (depending on the shade)
- Power: 80-95%
- Passes: 1-3 (but more passes = higher heat, which shifts the color)
The problem is that tiny variations in material batch or ambient temperature shift the color. I'm not 100% sure, but I think humidity affects it too. I've had two identical settings produce slightly different blues on consecutive days. So setup time jumps from 2 minutes (monochrome) to maybe 10-15 minutes of test passes for color work.
Verdict on Setup: Monochrome wins for speed and reliability. Color requires patience and test pieces. If you're doing production runs, color setup cost adds up fast.
Dimension 2: Material Versatility—What Actually Works
This was the dimension where my initial assumptions got overturned.
Monochrome Material Compatibility
The xtool s1 with the stock CO₂ module can handle a ton of materials: wood, acrylic, leather, glass, slate, cardboard, some plastics. Anything dark on light. It's super versatile. I've engraved cutting boards, coasters, phone cases, dog tags. All in black/white or grayscale.
The limitation? You're stuck with the material's natural color contrast. You can't create a red logo on a walnut cutting board. It'll just be a dark burn mark.
Color Engraving Material Compatibility
Color engraving with the xtool s1 is actually more limited, but for different reasons. The key materials that work well:
- Anodized Aluminum: Excellent color range (blues, reds, golds, greens). The heat bleaches the anodized layer and leaves a colored mark.
- Coated Stainless Steel: Good for dark contrast colors (black, dark blue, silver). Actually, the 40W diode module does a surprisingly decent job here.
- Some Ceramic Coatings: Hit or miss. I've had good results with white ceramic mugs producing dark brown/black text. But true color? Not really.
- Leather (for color burn): This was the surprise. If you use a specific leather with a painted finish, you can burn through the top coat to reveal a different color underneath. Not true color engraving, but a cool effect.
What doesn't work well for color engraving on the xtool s1: raw wood (it just burns), dark acrylic (no contrast), most plastics (melts or yellows unevenly).
Verdict on Materials: Monochrome is more versatile day-to-day. But for items like tumblers, metal signs, or keychains, color engraving adds a premium touch that monochrome can't touch.
I should note—this is based on my experience with the 20W and 40W modules. The CO₂ module behaves differently for some coated metals. Your mileage may vary if you're using a different laser module or a newer material batch.
Dimension 3: Output Quality—The Real Difference
This is where I had a major mindshift. I used to think color engraving would look cheap or inconsistent. In practice, when it's done right, it looks substantially better than monochrome for specific items.
Monochrome Output
Clean, sharp, reliable. For text and simple logos, it's hard to beat. On dark wood, it gives a classic, premium look. On acrylic, it's crisp. The xtool s1 produces very clean edges—no charring if you use the right air assist settings.
The limitation: it's always the same color. You can't do a gradient of blue to green. You can't add a red accent to a black logo.
Color Engraving Output
Done well, color engraving on anodized aluminum can look like screen printing. I've done a run of 50 keychains for a brewery with their logo in a metallic gold. It looked genuinely premium. The client was ecstatic. I charged a 40% premium over my standard monochrome rate.
But—and this is a big but—color consistency is a real issue. I had one order where 12 out of 80 tumblers came out with a visible color shift due to a worn laser module. We caught it when the customer rejected the batch. That cost us $340 in redo plus shipping. Lesson learned: you need to quality-check every single piece in a color run. You can't batch-check like you can with monochrome.
Verdict on Quality: Color wins for wow factor and premium pricing. Monochrome wins for consistency and scalability.
Dimension 4: Cost & Time—The Bottom Line
Let's talk money, because that's what my boss cares about.
Monochrome Cost Profile
- Setup time per order: 2-3 minutes
- Per-piece processing time: Fast (e.g., small logo on wood ~45 seconds)
- Rejection rate: ~1-2%
- Material cost: Standard laserable blanks
- Pricing: $2-5 per piece for simple work
Color Engraving Cost Profile
- Setup time per order: 10-15 minutes (test passes)
- Per-piece processing time: Slower (e.g., full-color logo on tumbler ~3-4 minutes)
- Rejection rate: ~8-12% (based on 50+ orders)
- Material cost: 30-50% more for coated/anodized blanks
- Pricing: $8-18 per piece for custom color work
The math is pretty clear: color engraving can be way more profitable per piece, but you absorb higher risk and slower throughput. On a 200-piece order, a 12% rejection rate means 24 items to redo. That's basically a full extra day of machine time and material.
Verdict on Cost: Monochrome is the safe, scalable workhorse. Color engraving is the premium add-on. Don't build your whole business around color unless you have a high tolerance for do-overs.
When to Use Which (Based on 9 Months of Screwing Up)
Okay, so here are my practical, experience-based recommendations. Take them with a grain of salt—your specific market might differ.
Choose Monochrome When:
- You're doing high-volume orders (100+ pieces)
- The material is wood, acrylic, or dark leather
- Your design is mostly text or simple shapes
- You need fast turnaround (under 3 days)
- The client hasn't specifically asked for color
Choose Color Engraving When:
- The item is a premium product (gift, corporate award, high-end merchandise)
- You're working with anodized aluminum or coated metal
- The design includes gradients, multiple colors, or detailed imagery
- You can charge a 40-100% premium over monochrome rates
- You have time for test runs and quality checks
What About the xtool s1 Laser Modules?
I've used the 20W module for monochrome stuff—it's fine. The 40W module is noticeably better for color engraving on metals (more power = faster passes = less heat bleeding = cleaner color). The CO₂ module is great for acrylic and wood, but I haven't tested it extensively on coated metals for color work.
If you're just getting started, I'd say get the 20W module and stick to monochrome for your first 3 months. Learn the machine. Then add the 40W module if you see demand for color work. Don't buy the 40W upfront unless you already have a client pipeline for metal engraving.
According to USPS (usps.com), as of January 2025, a small package (up to 4 oz) ships for around $4.50 Priority Mail. If you're doing color work, factor in the higher weight of coated metal blanks—freight costs add up.
Final Thoughts
Color engraving on the xtool s1 isn't a gimmick. It's a genuine capability that, when used right, produces stuff you can genuinely upsell. But it's also a pain in the ass compared to monochrome. More setup, more waste, more quality control.
The vendors who list their setup fees and material premiums upfront? I've learned to trust them more than the ones who quote a low price and then tack on "color processing" charges later. Transparent pricing is a green flag in this industry.
Anyway, that's my experience. I'm not a production manager, so I can't speak to optimizing workflow for a full-time shop. But from a small studio perspective, where every hour of machine time matters, this is what I've found works.
Prices as of this writing; verify current rates with your supplier. And don't skip the test passes on color jobs—learned that one the hard way.
