The Antalis move follows on the heels of Map Merchant Group's announcement that it would raise prices by between 5-8% from 4 October (PrintWeek, 9 September).
A number of independent merchants believe they are in a better position to maintain prices, as they are able to look for better deals.
"If mills do apply increases it means I can shop around as there are plenty of mills keen to get into bed with us," said one source.
Antalis marketing director James Jarvis said the group was currently in negotiation with suppliers to mitigate the impact.
However, he said the firm was facing increases of up to 10% dependent upon supplier and grade, from this month.
"We realise any increase will not be welcomed, but we have no alternative but to increase our prices by between 5% and 10% from 11 October."
How many other merchant companies follow Map and Antalis' lead remains to be seen, but the market is set to be active over the next few weeks.
