The First Minister has been urged to make different decisions from Westminster on press regulation ahead of the publication of a Scottish response to the Leveson inquiry.
Liberal Democrat leader Willie Rennie said a system of "carrots and sticks" will be required to bring the press on board with the recommendations of a panel led by Lord McCluskey, which is due to report back.
The five-person panel of legal experts and journalists was appointed in December to consider the recommendations of the Leveson report into press standards.
It was chaired by Lord McCluskey, senator of the College of Justice and a former solicitor-general, with a view for the panel to assess reforms to the Scottish press under Scots Law and make recommendations to the Scottish Government.
Speaking on BBC Radio Scotland's Good Morning Scotland programme, Mr Rennie said: "We need to make some different decisions, for instance about the authentication body that will be necessary, and also the carrots and sticks that will encourage the industry to participate in any system, so we need to see how those things will work in practice before we can make any judgments about how it will be implemented in Scotland."
The First Minister held a cross-party meeting with the Scottish Newspaper Society earlier as part of planned engagements with stakeholders after the publication of the Leveson Report.
A Scottish Government spokesman said: "The meeting gave all of the main party leaders in Scotland the opportunity to listen to the views of the press in Scotland as the Scottish Parliament prepares to respond to the recommendations made by Leveson.
"The report by the expert group, led by Lord McCluskey on how the Leveson recommendations could be applied in the Scottish context, is expected to be published on Friday and we will continue discussions with other parties on the next steps."
The publication of the Scottish document will come the day after David Cameron decided to dodge cross-party consensus on press regulation at Westminster, where he will force a vote on the issue in the House of Commons on Monday.
The Prime Minister said he will publish a Royal Charter to underpin a new self-regulatory system for the press without the need for parliamentary legislation, and Labour in Westminster is expected to publish its amendment for what was being described as a "Leveson-compliant" royal charter.
