Your label design looks perfect on screen. You hit print and… the image is shifted to one side, there are white lines along the edges, or the print is cut off on one side and has a gap on the other. The design hasn't changed — the print is just not landing where it should on the physical label.
This is a print positioning problem, and it's one of the most frustrating issues with Epson ColorWorks printers (C3500, C4000, C6000, C7500). The good news: there are three ways to fix it. The bad news: the driver method involves digging through multiple settings pages and will likely need readjusting every time you load a new roll.

Why Print Alignment Goes Wrong
There are several reasons your print doesn't land centered on the label:
- Mechanical tolerances — the print head, label path, and sensor all have tiny positional variations. Even printers of the same model can have slightly different alignment.
- Label roll positioning — the roll can sit slightly left or right in the printer. Different rolls from the same manufacturer can vary by fractions of a millimeter.
- Backing paper vs label edge — if the backing (liner) extends beyond the label edge, the sensor may reference the liner edge instead of the label edge, causing a consistent offset.
- Label dimension rounding — if you entered slightly larger dimensions than the actual label, the printer centers the design on the entered size, not the physical label size.
Method 1: Adjust Offsets in the Epson Printer Driver
This is the official way to fix alignment. Epson's driver has dedicated offset controls buried in the Printer Utilities section:
Go to Windows Settings → Printers & Scanners, click on your Epson ColorWorks printer
Click "Printing Preferences"
Click the 4th tab at the top: "Printer Utilities" (or "Utility" depending on driver version)
Click "Printer Preferences" or "Printer Settings" — this opens a separate popup window
In the first window that opens, you'll see three critical adjustment fields:
| Setting | What It Does | When to Use |
|---|---|---|
| Print Start Position | Shifts the entire print vertically (in the feed direction) — earlier or later on the label | Print is too high or too low on the label |
| Horizontal Adjustment of Paper Tip Position | Shifts the print left or right across the label width | Print is shifted to the left or right, white line on one side |
| Cut Position Adjustment | Adjusts where the cutter activates (for printers with a cutter) | Labels are being cut at the wrong position |
Adjust the values in small increments — these are typically in 0.1mm steps. Start with +0.5mm or -0.5mm and test
Print a test label after each adjustment to see the effect
Repeat until the print is centered on the label
This is a delicate process and the values are specific to the current label roll and its position in the printer. When you load a new label roll, the alignment will almost certainly shift slightly — and you'll need to go back into these settings and readjust. For businesses printing multiple label runs per day, this becomes a serious time sink.
Method 2: The Oversize Trick (Simpler & More Reliable)
Instead of fighting with sub-millimeter offset values, there's a simpler approach: make your design slightly larger than the actual label. This causes the print to "bleed" over the label edges, eliminating white lines entirely.
How It Works
If you have a 50mm × 50mm label but your design is also exactly 50mm × 50mm, any tiny misalignment creates a visible white line on one edge. But if your design is 51mm × 51mm, the print extends 0.5mm past each edge — so even with slight misalignment, the entire label surface is covered.
The Scaling Rule
Add 1mm to each dimension, proportionally:
| Actual Label Size | Design Size (Oversized) | Oversize Amount |
|---|---|---|
| 50mm × 50mm | 51mm × 51mm | +1mm each side |
| 100mm × 50mm | 101mm × 50.5mm | +1% proportional |
| 100mm × 70mm | 101mm × 70.7mm | +1% proportional |
| 76mm × 51mm | 77mm × 51.7mm | +1mm width, proportional height |
If your label is 100mm × 50mm (2:1 ratio) and you oversize to 102mm × 51mm, you maintain the aspect ratio. If you did 102mm × 52mm, the design would be slightly stretched vertically. Keep the ratio consistent so your design doesn't distort.
Oversizing eliminates white lines by printing beyond the label edge onto the backing paper. This works great for labels with colored backgrounds or full-bleed designs. If your design has a white background, white lines won't be visible anyway — oversizing isn't necessary in that case.
Method 3: Combine Both (For Persistent One-Side Issues)
Sometimes oversizing alone doesn't fix the problem — if the print is consistently shifted to one side (e.g., always a white line on the left), you need to combine both methods:
Oversize your design by 1mm on each dimension (Method 2)
Print a test label — check if one side still has a larger gap
If the white line is on the left or right, adjust the Horizontal Adjustment in Printer Utilities (Method 1)
If the white line is on the top or bottom (feed direction), adjust the Print Start Position
Test print again and refine until the design covers the entire label
The Real Problem: Every New Roll = Readjust
Here's why this is so frustrating for production environments: offset values are specific to the current roll and its position in the printer. When you swap in a new roll — even the same size from the same manufacturer — the alignment shifts slightly. The roll might sit 0.3mm further left, or the first label might be positioned differently.
This means:
- You adjust offsets perfectly for Roll A
- Roll A runs out, you load Roll B
- Roll B is shifted 0.5mm — your offsets are wrong again
- Back into the driver settings, readjust, test print, repeat
For businesses doing dozens of label runs per day, this offset dance is a real productivity killer.
In LabelInn, offset settings are right in the print dialog — not buried in 4 layers of driver menus. When you test print and see the alignment is off:
- Adjust the vertical or horizontal offset directly in LabelInn
- Hit test print again immediately
- Done in seconds — no driver pages, no Printer Utilities, no popup windows
When you load a new roll, you just tweak the offset value in LabelInn and keep printing. The entire adjust-test-print cycle takes 10 seconds instead of 5 minutes fighting with the driver.

How do I know if I need vertical or horizontal offset?
Look at where the white line or gap is on your printed label. If it's on the left or right side, you need horizontal adjustment. If it's on the top or bottom (the leading or trailing edge in the feed direction), you need vertical (Print Start Position) adjustment.
Will oversizing by 1mm affect print quality?
Not visibly. A 1mm oversize on a 100mm label is a 1% increase — the scaling is imperceptible to the human eye. Your text, barcodes, and images will look identical. The only difference is that 0.5mm of your design extends past each label edge onto the backing paper.
Does LabelInn support offset settings for Epson ColorWorks?
Yes. LabelInn has built-in offset controls for both vertical and horizontal positioning, accessible directly from the print dialog. You can adjust and test print without opening any driver settings.
Why do I need to readjust offsets when loading a new roll?
Each label roll has tiny manufacturing variations — the label position on the backing, the roll width, and how it sits in the printer can all vary by fractions of a millimeter. Since Epson ColorWorks has high precision, even these small variations are enough to shift the print noticeably.
Can I use the oversize trick with die-cut labels?
Yes, and it works especially well with die-cut labels. The oversize portion prints on the backing paper around the die-cut label — when you peel the label, only the label surface is visible, and it's fully covered with no white edges.
