A reusable self-inking stamp made from the logo uploaded through the product personaliser.
Upload with confidence
The production file follows the submitted personalisation, so inspect the complete on-page preview rather than relying only on the source logo.
Upload the original file where possible. Avoid screenshots, blur, shadows and surrounding page content.
Keep every letter, line and logo element comfortably inside the impression boundary.
Check orientation, scale, cropping and small detail before ordering the personalised stamp.
Brand colours, gradients and photographs are not printed as they appear on screen. The rubber die creates the design using one selected ink colour.
A small low-resolution image can look acceptable on screen but produce rough or unclear artwork when enlarged for production.
Where it works
Use the self-inking mechanism for consistent one-colour marks on suitable matt surfaces.

Before you order
Use the clearest original file accepted by the uploader. A high-resolution image with a plain or transparent background is preferable to a screenshot, compressed preview or photograph of a screen.
No. A conventional rubber stamp creates the complete design in the selected ink colour. Check that the logo remains recognisable as solid one-colour artwork without gradients, shadows or photographic effects.
Measure the intended stamping space and inspect the smallest lettering or fine detail in the preview. Choose a larger impression if important elements become cramped or difficult to read.
Artwork is checked for engraving suitability before manufacture. You should still review the complete personalisation, spelling, scale, orientation and cropping carefully before placing the order.
No. Standard self-inking ink is water-based and intended for absorbent matt paper and card. It is not suitable for glossy, coated or non-porous packaging, and clothing requires the textile-stamp range.
Self-inking stamps normally use replaceable cartridges. Match the replacement pad to the exact stamp model shown on the product or contact Stamp Ninja before ordering a cartridge.
