Some basic rules of thumb for designing for video

  1. Save your images as 24 Bit RGB Color at 72 ppi (dpi).
  2. Design your image file at 720x540 for NTSC graphics and resize down to
    720x486 for final output. (square to rectangular pixel adjustment)
  3. Design your image file at 768x576 for PAL graphics and resize down to
    720x576 for final output. (square to rectangular pixel adjustment)
  4. A pure white background will flicker on the television, and may cause
    text to flicker. Use an light grey/off white (234,234,234) colored
  5. Use maximum R, G, B values of 234 or less.
  6. Run Photoshop's NTSC video filter on your graphic for it to bring colors
    back into "safe" range.
  7. Action Safe is 90% of your screen size and is considered safe for
    elements other than text that still needs to be seen.
  8. Title Safe is 80% of your screen size and is considered safe for all
    text and elements that "must" be seen.
  9. Account for the Interlaced Scanning found in NTSC and PAL television
    sets. To avoid flickering, make sure all fine lines are at least 2
    pixels wide and that any width is defined in multiples of 2 pixels.
  10. 24 point fonts are best for television readability. A 14 point font,
    bold, is the absolute minimum size to use.
  11. Anti-alias all text to avoid sharp edges.
  12. Leave around a 25 pixel border from the edge of the graphic so that any
    element doesn't appear exactly at the edge of the screen.
  13. Look at your work on a native video monitor (in addition to the computer display) to see how it looks on a television used in someones home. What you see on your monitor will most likely look better then what someone will have on their home TV.

Epson Perfection 4490 Photo - Flatbed Scanner

A premium value for professional quality scans, the Epson Perfection 4490 Photo delivers extraordinary results with 4800 x 9600 dpi resolution and an impressive 3.4 Dmax.

Epson Perfection 4990 Photo

Overall the Epson Perfection 4990 Photo is an excellent all rounder. It should handle any scanning task you throw at it with ease and produce stunning results. That said, it is expensive and this expense can't really be justified unless you're in need of a scanner with high end film scanning functions. If this is what you want then the 4990 can't be faulted.

epson perfection V700 photo Scanner

The big question though is whether the V700 is worth buying. The answer is yes, but only if you're a seriously dedicated photographer and money is no object. There is a corresponding jump in performance for the extra money paid over the 4990's and the V700 undoubtedly offers better quality scans, but the fact is for most people the 4990 should be good enough.

Brother HL-2040

At its default settings, the HL-2040's text quality is perfectly adequate for everyday use. In our tests, I saw some fuzziness in the finest characters and jagged edges on diagonals, but closely spaced bold characters (which challenge so many lasers) remained separate. Line art was too grainy for my liking, and a greyscale image suffered from a blown-out appearance, in which dark areas became too dark and highlights washed out completely.

Brother HL-2140

Quality is actually surprisingly good. You wouldn't want to use the Brother HL-2140 for any kind of serious graphical work - it's fine for printing out street maps and other such drawings, but photos are a definite no-no.
If you're looking to print thousands of pages a month then the Brother HL-2140 definitely isn't a good buy. But provided you won't generally be printing more than a handful of documents a day, you shouldn't end up being too put out by the running costs.
