Complete Guide to Thermal Shipping Label Cropping & Warehouse Packing
Learn how high-volume Indian sellers on Flipkart, Meesho, Amazon, Myntra, and Ajio format 4×6 inch thermal labels, eliminate wrong shipments with SKU sorting, and maintain 100% barcode scan rates.
Guide #1
Flipkart Seller Hub & E-Kart Logistics
How to Crop Flipkart Shipping Labels for 4×6 Thermal Printers Without Losing SKU Details
When you download shipping labels from the Flipkart Seller Hub, Flipkart generates an A4-sized PDF document where the top-center rectangle contains the E-Kart Logistics shipping label (including the customer address, 2D QR code, vertical AWB barcode, and SKU ID table) while the bottom half contains the customer's GST Tax Invoice.
If you try to print this default A4 PDF directly onto a 4×6 inch (100 × 150 mm) direct thermal printer, the entire page shrinks to become unreadable, and the courier pickup executive's scanner will fail to scan the E-Kart barcode.
Step-by-Step Flipkart Cropping Workflow:
- Download Your Batch PDFs: In Flipkart Seller Hub, go to Orders → Active Orders → Generate Labels and save the PDF files to your computer.
- Select the Flipkart Preset on Skyzoon: Open the Flipkart Label Cropper tab. Our smart boundary detector automatically locates the top
STD | E-Kart Logistics border down to the Not for resale / Printed at footer line.
- Enable Sort by SKU (Recommended for 20+ Daily Orders): Select Sort by SKU so all identical sarees, garments, or electronics print sequentially.
- Download & Print: Click Prepare & Download Cropped Labels PDF. Because Skyzoon uses lossless vector PDF cropping, every barcode line stays razor-sharp at 203 DPI and 300 DPI.

Meesho Supplier Panel Workflow
Meesho Shipping Label Cropping & Automatic SKU / Size / Quantity Stamping
On Meesho, orders are shipped via courier partners like Valmo, Delhivery, Xpressbees, Shadowfax, and Ecom Express. A common challenge for Meesho suppliers is that product details (such as SKU, Size, Color, and Quantity) are often printed in the bottom Tax Invoice section rather than inside the top shipping label box.
When you crop off the bottom tax invoice for a 4×6 thermal sticker, your warehouse packers might not know which size (`M`, `L`, `XL`, `XXL`) or quantity belongs to that label.
How Skyzoon Solves the Meesho Packing Problem:
- Automatic Text Extraction: Before removing the bottom invoice, our browser engine reads the PDF text layer and extracts the exact
SKU, Size, and Quantity.
- Clean Footer Stamp: When you enable Stamp Extra SKU & Qty Footer Bar on Label, Skyzoon prints a bold, readable strip at the bottom of the 4×6 label showing the exact item to pack.
- Multi-Quantity Order Alerts: If a customer ordered 2 or 3 pieces in a single sub-order, enabling Highlight Multi-Quantity Orders adds a `[MULTI-QTY]` warning badge so your staff never short-ships an order.

Hardware Setup & Calibration
Troubleshooting Blurry Barcodes & Configuring 4×6 Thermal Printers (TSC, Xprinter, TVS, Zebra)
Even with a properly cropped vector PDF, incorrect printer driver settings in Windows or macOS can cause barcodes to print faintly or skip blank labels. Use the reference table below to configure your thermal printer for maximum scan reliability:
| Printer Parameter |
Recommended Setting |
Why It Matters |
| Paper / Roll Size |
4 × 6 inches (100 mm × 150 mm) |
Standard e-commerce shipping sticker dimension across India. |
| Print Speed |
3.0 in/sec to 4.0 in/sec |
Slower speed allows the thermal head to heat evenly for dark barcode bars. |
| Darkness / Density |
10 to 12 (out of 15) |
Prevents faded barcodes while avoiding thermal smudge. |
| Dithering / Halftone |
None (Threshold / Black & White) |
Ensures solid black barcode lines instead of dotted gray patterns. |

Cost Saving for New Sellers
How to Print 4 Shipping Labels on 1 A4 Sheet Without a Thermal Printer
If you are a new seller on Flipkart, Meesho, or Amazon and do not yet own a dedicated 4×6 thermal barcode printer, printing 1 order per A4 sheet wastes 75% of your paper and toner.
Inside the Skyzoon Label Cropper tool, simply change 2. Thermal / Printer Page Size to A4 Paper — 4 Labels on 1 Sheet (2×2 Grid). The tool automatically places 4 cropped shipping labels onto a single A4 page with subtle center cut lines—compatible with standard 4-quadrant self-adhesive A4 sticker sheets available on Amazon and Flipkart.
