Goss Printing Press Maintenance & Relocation: FAQs from a 5-Year Service Engineer

I've been handling Goss press service orders for five years. In that time I've made (and documented) at least a dozen significant mistakes, totaling roughly $18,000 in wasted budget and downtime. Below are the questions I get most often—along with the answers I wish someone had given me before I learned them the hard way.

What does Goss press maintenance actually cover?

It's more than just oiling and wiping down rollers. Full maintenance includes:

• Inking and dampening system calibration
• Roller pressure adjustments (too tight and you wear out bearings, too loose and you get ghosting)
• Color consistency checks—I use a spectrophotometer to verify Delta E is under 2 for brand-critical jobs. Industry standard says Delta E < 2 for spot colors, and I've found that making this a monthly check catches drift before a client rejects a run.
• Lubrication of all moving joints (note to self: don't assume the previous tech did it)
• Web tension control inspection for presses running reels

One mistake I made early on: I skipped the roller pressure check because the press was “running fine.” Three months later the client complained about uneven ink coverage. Turns out the rollers had shifted by 0.5 mm—cost us $900 in reprints plus a 2-day delay. Now I check every press's roller settings at least quarterly, and I keep a log of measured values so I can spot trends.

What's the most common maintenance mistake?

Assuming your press is “fine” because it still prints. I've seen operators run a Goss press for years without recalibrating the registration system, thinking the slight misalignment was “normal.” They heard “the press needs a full service” but only scheduled a quick oil change. The result: ever-worsening color registration until a customer rejected a $4,200 order. That's when they finally did the full calibration—and the press ran perfectly again.

The lesson: If you skip the annual full service, you'll pay for it in waste and rework. I'm guilty of this too—I once ignored the factory-recommended 12-month service interval because the press “seemed okay.” The technician who eventually did it found three rollers out of spec and a worn bearing that could have caused a catastrophic failure. (Should mention: the cost of that emergency repair was five times the regular service fee.)

How risky is relocating a Goss press?

I want to say it's straightforward, but I've seen too many things go wrong. The biggest risk isn't the move itself—it's the re-leveling and recalibration afterward. Goss presses are heavy, precision machines. If the foundation isn't perfectly level (within 0.001 inch per foot, depending on model), you'll have registration problems that are nearly impossible to diagnose later.

In September 2022, I supervised a relocation where the rigging team did everything right except they didn't check the floor slab thickness. They bolted the press down, but the concrete had a hairline crack. The press shifted 2 mm over six months. Cost us $3,200 in diagnostics and re-leveling. If I remember correctly, the manufacturer's manual says to always pour a dedicated concrete pad for a press over 40,000 pounds. The client had skipped that step. (Mental note: add floor inspection to our relocation checklist.)

Can I use 3D printing to make replacement parts for my Goss press?

Short answer: sometimes, but you need the right material. I tried this myself after a customer's plate cylinder clamp broke on a Friday. I thought, “I'll just 3D print a quick replacement.” Used standard PLA. It melted after 30 minutes at 120 °F (the press runs hotter near the dryer section).

What you really need is heat resistant 3D printer filament—something like PETG, polycarbonate, or nylon that can withstand at least 100 °C. I've had success with polycarbonate for non-structural parts (like duct adapters or sensor brackets). But for load-bearing parts like gears or grippers, stick with OEM metal components. I learned that lesson after a PLA cam gear disintegrated and jammed the conveyor—$500 in cleanup plus a missed deadline.

If you're thinking about selling 3D printer ideas: custom fixtures for press maintenance (roller stands, alignment jigs) sell well among print shops. But be honest about your material limitations.

Any 3D printer ideas to sell — besides press parts?

I run a side Etsy shop, so I can share what's worked for me. (Full disclosure: I'm better at Goss presses than 3D product design, but I've made enough mistakes to have opinions.)

The best-selling items I've seen from other printer owners include:

• Custom phone stands with integrated cable management
• Miniature architectural models (architects love these for client presentations)
• Packaging prototypes — print a concept box before going to full offset production (this directly ties back to Goss work)
• Personalized cookie cutters and stamp handles

The key, I've found, is to solve a specific problem. “Just a cute statue” rarely sells. For example, a friend of mine prints replacement knob covers for old industrial equipment (not just Goss) and sells them for $8 each—he's sold over 400. That's a better business idea than generic trinkets.

How do I scan from an HP printer to my computer?

I get this question surprisingly often from press operators who also manage office documents. Here's the straightforward method for most HP multifunction printers (OfficeJet, LaserJet, etc.):

1. Make sure the printer is connected to the same Wi‑Fi network as your computer.
2. Place the document face-down on the scanner glass (or in the ADF).
3. On the printer's control panel, select Scan → Scan to Computer → select your computer's name (you may need to install HP Smart software first).
4. The scan will appear in the default folder (usually Documents/HP Scans).

If you don't see the option, check that the HP Smart app is running in the background. I once wasted 20 minutes because the software was minimized and the printer couldn't “see” my PC. Oh, and for high-volume scanning of proofs, consider using a dedicated scanner—HP's ADF can handle 20 pages, but for 200-page jobs, a sheet-fed scanner is faster. (I really should buy one myself; I've been meaning to for months.)

How do I maintain color consistency on my Goss press?

This is the number one reason print buyers switch vendors. According to industry standards (Pantone Color Matching System guidelines), color tolerance should be Delta E < 2 for brand-critical colors. Delta E of 2–4 is noticeable to trained observers; above 4 is obvious to most people.

To keep your press consistent:

• Calibrate your densitometer/spectrophotometer weekly
• Check ink density at the beginning of every shift
• Use a color bar on every sheet and measure it at least once per run
• Control environmental conditions heat and humidity affect ink tack and drying

I once overlooked humidity after a relocation. The new press room had an HVAC system that kept temperature constant but let humidity swing from 30% to 65%. The color on Monday looked completely different from Friday's output. That mistake cost us a $3,200 reprint plus a week of lost trust. Now I monitor humidity religiously (mental note: buy a second hygrometer for the annex).
