07 / CUSTOM LABELLING — ARTWORK SPECIFICATION
Your artwork on the vial.
Every 10 vials ship seated in a clear plastic clamshell. The clamshell lid carries the compound name, strength, lot number, MFG date and the research-use statement; the vials themselves are unlabelled. Choose custom labelling to add your own artwork to each vial — the clamshell stays labelled as standard. Custom labelling is $1.00 per vial from 100 vials per SKU, chosen on the product page; you see a rendered proof before the line goes in your cart, and Certamer signs the proof off before print.
DIE-LINE AND FILE
| Trim size | 38 × 19 mm |
| Bleed | 3 mm each side |
| Resolution | 300 DPI minimum · 520 × 295 px at bleed · 449 × 224 px at trim |
| Formats | PNG, JPEG or SVG for upload and the on-screen proof. A print PDF can follow by email once the proof is approved. |
| Colour | RGB accepted, CMYK preferred. Screen proofs are indicative. |
| Smallest text | 5 pt |
| Reserved strip | 8 mm on the right edge where Certamer prints the lot number, MFG date and the research-use statement. Your art must not use that strip; it is printed on every vial regardless of design. |
| Die-line status | Current vial stock. Certamer confirms the die-line in writing on every custom-label order before anything is printed. |
The template marks bleed (red), trim (black), a 1.5 mm safe area (green) and the reserved strip.
HOW A CUSTOM-LABEL LINE RUNS
- On the product page choose Custom labelling at 100+ vials, give the brand name and upload the artwork.
- Render the proof: your art on the photograph of the vial we ship, plus the flat label with the reserved strip marked. Approve it to add the line.
- Place the order. The proof and artwork travel with the order line into Certamer’s label queue.
- Certamer approves the proof (or sends it back with a note on the order page) before print. Nothing is printed or applied without that sign-off.
- The lot is allocated, labelled and shipped with its certificate of analysis. The lot number on the strip binds each vial to that certificate.
