Lawrence Wallis in today's Printweek is realistic about change and the headline even finds a welcome for changes in technology. It is suggested that moving upmarket to higher quality is only a short term remedy when new techniques become possible. Two examples are given. "Most seismic was the onset of desktop publishing (DTP) in 1985 that rocked and destabilised the prevailing pre-press establishment." There, that is enough direct quoting. You can't just copy stuff out of Printweek as if it was something from the blog of Roy Greenslade.
The second example given is colour repro on personal computers sometime later. Once described as "good enough" this is now apparently widely accepted.
There is still professional pre-press of course but at IPEX the term most widely used was "pre-media". There is still some video editing kit that is not available at Currys Digital.
But for DTP it is now possible to imagine that the technology available at home is good enough for most purposes. Amazon probaly stock most of what anyone would need.
