Anybody know of a product that handles the recurrent screenshot nightmare
of illegible text?
A virtual friend in New Zealand mailed a tip from Dov Issacs of Adobe
which was posted to another forum.
The answer is to shoot the screenshot and start a new document window
which Photoshop automatically sizes to the dimensions of what's on
the clipboard, of course.
From here on out no destructive JPEG and no descructive downsizing of
the screenshot dimensions:
Use binary EPS as format and set Image Interpolation in the PS6 EPS
export dialog. This enables an image dictionary key that tells PSL2,
PSL3 and Acrobat to do a practically perfect interpolation to the
rendering resolution of the actual device whether a monitor or a
printer.
When the PDF is created, downsampling is set to OFF (a screendump is
72 dpi already) and compression to ON in InDesign, Illustrator or
Distiller.
Dov's original post says to enable PostScript Color Management and
embed CMYK, RGB, gray, but as enabling PSCM in any case converts to
Lab whether in InDesign or Distiller, that step might as well be done
right off the bat, and then neither embed ICC nor CSA information.
The PS6 Color Settings dialog unfolded to show Advanced Mode, placed
in ID152 and exported with maximum quality compression: As Lab 100
Kb; as ICCBased gray: 184 Kb; as deviceGray: 94 Kb.
The effect is incredible. You can zoom in to 200% ... 400% and it's
still perfect.
