Rectangular Printer cartridge
For COLOP Printer 20 and Printer C 20 / Compact 20.
Illustrative shape only—match the printed code
Exact fit
Use this list together with the model printed on your stamp body. Similar dimensions do not make a cartridge interchangeable.
This is a rectangular-family cartridge. A square E/Q cartridge with the same number is a different shape and fit.
Current options
Standard pre-inked colours are water-based and intended for absorbent matt, uncoated paper and card. Do not use them as a general solution for glossy packaging, coated stock, plastic, metal or other non-porous surfaces.
E/20 note: use the specifically named textile/fabric-marking black variant for the intended fabric-marking application; the ordinary colour variants remain for paper and card.
Dry – No Ink: supplied uninked. Add only an ink confirmed as compatible with the pad, rubber text plate and intended surface.
Clean replacement
Work over scrap paper and avoid touching the inked pad surface. Exact lock positions vary slightly by stamp model.
Press the stamp down only a few millimetres—just enough to release pressure from the cartridge.
Use the side locks while the stamp is held slightly compressed. Keep fingers clear of the rubber text plate.
Push the old cartridge out from one side while guiding the new E/20 pad in with the inked face down.
Release the locks, make several impressions on scrap paper and allow the ink to distribute evenly.
Check that the cartridge is fully seated and correctly oriented. Remove dried paper fibres or debris from the rubber text plate carefully, then test again without adding excess ink.
Fit a fresh matching cartridge at the same time. The previous design can leave a lasting depression in the old pad and cause uneven inking on the new text plate.

Useful answers
This product is currently sold as a pack of three genuine COLOP replacement pads. Check the quantity and selected colour shown in the basket before completing the order.
Not necessarily. Match the complete E/ code and exact stamp model. The casing, rails and depth can differ even when two pads look similar or produce a similar impression size.
Standard pre-inked colours are water-based and intended for absorbent matt, uncoated paper and card. They are not a general solution for glossy, coated or non-porous surfaces.
The cartridge is supplied without ink. Add only an ink confirmed as compatible with the pad, rubber text plate and intended surface; an unsuitable ink can damage the stamp or produce poor impressions.
A fresh matching pad gives more even ink distribution and avoids overfilling. COLOP recommends replacing the cartridge rather than repeatedly refilling an old, compressed or contaminated pad.
The previous rubber design can leave a lasting depression in the pad surface. A new cartridge helps ink the replacement text plate evenly from the first impression.
