I know the pad code
Match the complete code printed on the existing pad cassette, including every letter, slash and Q.

The safest match uses two checks: the full E-code on the existing cassette and the COLOP model on the stamp casing. Never rely on the number alone.
E/30 and E/Q30 are different. Every letter and symbol matters.
Read the full code
E / 30pad code + stamp model
Example code only — match the code on your own cassette.
01
Read the whole E-code
Letters, slash, Q and number identify the pad family.
02
Confirm the casing model
Cross-check it against the current product compatibility list.
03
Choose an offered colour
Options vary by pad and live availability.

Do not match by shape
Similar-looking cassettes are not necessarily interchangeable.
Find the safest route
What information can you read on the stamp?
Use the full pad code first, then confirm the casing model.
I know the stamp model
Use the COLOP model name and number, then confirm the compatible pad code on the product page.
Find by stamp model →I have a Printer Q model
Square Q stamps use E/Q pads. The Q is part of the code and distinguishes them from rectangular pads.

| Pad code | Common family | Useful match | Important check |
|---|---|---|---|
| E/10 | Printer 10 / C10 family | Small rectangular COLOP models where the live compatibility list confirms E/10. | Do not choose from physical resemblance alone. |
| E/20 | Printer 20 / C20 family | Compatible Printer 20 and related rectangular models. | Read the exact model and listing before ordering. |
| E/30 | Printer 30 / C30 / Compact 30 family | Compatible medium rectangular models listed on the product page. | E/30 and E/Q30 are different shapes. |
| E/40 | Printer 40 / C40 family | Compatible wider rectangular COLOP models. | Confirm the complete code rather than only the number 40. |
| E/50 | Printer 50 / C50 family | Compatible larger rectangular COLOP models. | Model families and generations can differ; use the live listing. |
| E/60 | Printer 60 / C60 family | Compatible large rectangular COLOP models. | A large cassette that looks close is not sufficient evidence. |
| E/Q family | Square Printer Q models | The matching square Q model when the full E/Q code agrees. | The exact Q number must match; Q is not optional. |
Compatibility can vary across model variants and generations. Confirm both identifiers before purchase.
Three-step match
Read, cross-check, choose.
Two independent identifiers make an accidental mismatch much less likely.
Remove and read the old cassette
Look for the moulded or printed E-code. Copy the full code exactly, including E/, Q and the number.
Cross-check the stamp model
Read the COLOP model on the casing and make sure it appears in the replacement pad's current compatibility information.
Choose colour and fit carefully
Select an offered colour, keep ink away from clothing and insert the cassette in the same orientation as the original.
Most common mistake
Do not ignore the Q in an E/Q pad code.
A rectangular E/30 and a square E/Q30 are not substitutes. Copy the complete cassette code and compare it with the current compatibility list.
E/30 ≠ E/Q30

Replacement-pad FAQs
Avoid the easy-to-make matching errors.
A few seconds checking both codes can prevent the wrong order.
Where can I find the COLOP replacement-pad code?
It is normally printed or moulded on the removable ink-pad cassette. Remove it carefully and look for a complete code such as E/30 or an E/Q code.
Is E/30 the same as E/Q30?
No. E/30 is a rectangular pad code and E/Q30 denotes a square Q-family pad. Match every character in the complete code.
Can I choose a pad by its dimensions or appearance?
That is risky because several cassettes can look similar. Use the exact pad code and cross-check the compatible stamp model on the live product page.
Which replacement-pad colours are available?
Common listing options may include black, blue, red, green, violet or dry, depending on the pad. Check the current product selector because options vary by model and availability.
What does a dry replacement pad mean?
A dry cassette is supplied without ink for a suitable specialist setup. Do not assume every bottled ink is compatible with the stamp, pad or intended surface.
Should I replace the pad or the whole stamp?
Replace the pad when the casing and rubber impression remain sound but the ink supply or pad is worn. Replace the complete stamp if the mechanism, casing or impression plate is damaged.
Have the full pad code and stamp model?
Open the replacement-pad range and confirm both against the current product information.
