The first issue of the free 16-page, full-colour tabloid will become available in local newsagents and shops on 30 May with an initial print run of 10,000. Trinity Mirror will print the newspaper on a fortnightly basis at its Cardiff plant.
Journalist Richard Gurner, who launched the Caerphilly Observer in 2009, said: "Publishing a fortnightly newspaper is hard work, but I am convinced it is the right move.
"The response we’ve had to the website from readers and business alike has been overwhelmingly positive, but the question they keep asking us is when are we going into print?
"Despite huge traffic numbers, there are still large parts of our community unfamiliar with the Caerphilly Observer. A print edition will expand our audience and grow our brand to reach people not already online."
The website currently attracts an average of 50,000 page views and 20,000 unique visitors a month, which it claims is more than the traffic to local Caerphilly newspaper Campaign’s website.
Gurner said that he was addressing a gap in the market for a newspaper dedicated to the entirety of the Caerphilly county borough.
He obtained a business grant from Caerphilly County Borough Council to help with the first four editions of the newspaper, which is part funded through the European Agricultural Fund for Rural Development (EAFRD) and the Welsh Government.
Caerphilly Observer to launch print edition
The Caerphilly Observer, a website covering news from the Welsh county, is to launch a print edition in response to demand from its readers for a paper counterpart.
