LabelCal: Exact Size Print

Ziro Labs

About this app

Stop guessing where your printer will land.

LabelCal is an exact-size label printing and printer calibration workbench. Measure the real output of your printer, save its correction, define physical label stock in millimetres, arrange a full sheet, and check every warning before you print.

CALIBRATE YOUR PRINTER
• Print a clear registration target
• Record horizontal and vertical offset
• Correct printer scale on both axes
• Verify the residual against a visible tolerance
• Reuse the calibrated printer and stock profile

BUILD PRECISE LABEL SHEETS
• Work in true millimetres from setup to output
• Set page size, rows, columns, label dimensions, margins and gaps
• Import an image or vector PDF with the Android system picker
• Create a text label directly on the sheet
• Fill all cells for a batch or edit individual labels
• Zoom, pan and select cells on a physical paper workbench

PROOF BEFORE USING PAPER
• Catch geometry that leaves the page
• See missing artwork and low-resolution warnings
• Confirm calibration status before a production run
• Review the complete A4 label sheet at a glance

PRINT OR EXPORT AT EXACT SIZE
• Print through Android's native print framework
• Save a precise A4 PDF with the correct physical media box
• Share the PDF with another device or printer
• Keep printer profiles and label projects available offline

PRIVATE BY DESIGN
LabelCal has no account, analytics, tracking or developer-operated cloud. It requests no network permission. Your project stays on your device, and artwork is accessed only when you choose a file with Android's system picker.

One upfront purchase. No subscription.

For accurate output, print at 100% or Actual Size and disable fit-to-page or printer scaling.
