Text conversion software specialist Stilo International is planning to invest in "e-book" technology after reporting a sharp rise in pre-tax profits in the half year to 30 June.Sales were flat at £1.1m, but pre-tax profits rose to £92,000 from £50,000 over the same period the previous year. Stilo's margins were boosted by strong sales of Omnimark, a content processing platform used by customers such as the British Library and the Japan Patent office."New Migrate services for automating EBOOK production are scheduled for release in the coming months, as the majority of commercial publishers seek to transition from print to new digital formats supported by a growing range of e-readers, tablets and mobile devices," said chairman David Ashman."The board intends to invest further in this area through additional product development, and by allocating greater sales and marketing resources to capitalise upon this exciting new business opportunity."Last month, Stilo announced a deal with the US IT giant Cisco to convert 20,000 of pages in Adobe format into the DITA (Darwin Information Typing Framemaker) standard.---RG
